Arcane

Piltover is a shining beacon of innovation in the region of Valoran: a city built on invention, trade and aspiration. Magic (or the “Arcane”) is historically dangerous and outlawed in the academic institutions of Piltover, because of its instability and the risk it poses. The world is one of high technology / high magic potential, blended in: the invention of Hextech (a fusion of arcane magic and machinery) marks a turning point where magic becomes harnessable via science. Piltover is a shining beacon of innovation — a city built on invention, trade, and aspiration. Magic, known as the “Arcane,” is a mysterious and dangerous force that was once forbidden due to its instability. However, the discovery of Hextech — the fusion of magic and machinery — has allowed Piltover’s scholars to harness it safely, ushering in a new age of progress. The world balances high technology and high magic, though access to either is controlled by elite institutions. Piltover prides itself on order, progress, and culture, while the undercity of Zaun struggles in the shadow of its success.

Primary Structure of the Setting The core setting consists of two vertically linked city-states: Piltover (upper city) and Zaun (undercity). They occupy the same physical region, separated by elevation, infrastructure, and social structure rather than distance. Both cities rest atop a complex coastal cliff system crossed by bridges, pipes, and old industrial tunnels. 1. Piltover — “The City of Progress” General Description: Piltover is a wealthy, coastal city built on a series of cliffs, terraces, and elevated plateaus overlooking the sea. It functions as a hub of invention, trade, and culture — a global crossroads for merchants, engineers, and scholars. Environmental Traits: Climate: Temperate maritime — cool winds from the ocean, frequent fog, but stable weather conducive to airship and sea trade. Architecture: Neo-industrial and art-deco inspired. Brass fittings, crystal lighting, and precision engineering dominate. Buildings integrate gears, lifts, and mechanical ornamentation. Lighting & Atmosphere: Clean, bright, and polished; sunlight and Hextech illumination are both symbolic of progress. Urban Layout: Council Heights – Seat of power; marble towers, the Academy, and Council Hall. Access restricted. The Academy District – Educational and research hub, home to laboratories, archives, and inventor guilds. The Market Terraces – Multi-level trade areas where Hextech components, imported materials, and art are exchanged. The Ports & Hexgates – Maritime docks and teleportation hubs connecting Piltover to the wider world. Residential Belts – Ranging from upper-class manors to modest engineer housing. Clean air, regulated industries. Sociopolitical Summary: Piltover is governed by the Council, a small assembly of powerful figures representing trade, innovation, and research sectors. The city’s identity is technocratic and meritocratic in theory but oligarchic in practice. Order, cleanliness, and reputation define its civic culture. 2. Zaun — “The Undercity” General Description: Zaun sprawls beneath Piltover’s foundations, within the caverns, lower terraces, and abandoned industrial infrastructure that descend toward sea level. The city is dense, polluted, and alive — a tangle of pipes, bridges, neon lights, and chemical fog. Environmental Traits: Climate: Stagnant, humid, filled with industrial smog. Sunlight rarely reaches deep levels. Architecture: Improvised, welded, and recycled. Structures cling to bridge undersides, tunnel walls, and factory frames. Everything leaks, drips, and hums. Lighting & Atmosphere: Harsh chem-lamps, colored smoke, and constant movement. The air carries the scent of oil and Shimmer. Urban Layout: The Lanes – Street-level districts filled with taverns, markets, and gang territories. The Factory Levels – Old manufacturing plants repurposed for chemtech production and Shimmer refinement. The Sumps – Lowest flooded sections, toxic runoff basins where the poorest live or hide. The Slagcanals – Industrial waterways used for smuggling and transport. The Breachways – Vertical shafts connecting to Piltover’s foundations; heavily guarded or sealed. Sociopolitical Summary: Zaun has no central government. Authority belongs to Chem-Barons — powerful industrialists and gang leaders who control resources and neighborhoods. Despite hardship, Zaun’s culture is resilient, inventive, and communal. It values freedom and innovation over regulation, even when that freedom is dangerous. 3. Physical Relationship Between the Cities Piltover and Zaun are geographically inseparable. Piltover’s lower industrial zones extend downward into the uppermost layers of Zaun, creating transitional sectors where both cities overlap. Piltover relies on Zaun’s labor, materials, and chemical industries. Zaun depends on Piltover’s infrastructure, trade networks, and protection from external threats. The result is a vertical ecosystem — technological symbiosis built on exploitation. 4. Surrounding Regions (Implied by Lore) Although Arcane centers on the twin cities, several external zones are acknowledged in dialogue and lore: The Coastline and Trade Routes: Piltover maintains ports and Hexgates linking it to distant continents and inland cities. Crystal Mines: Remote locations where raw Hex Crystals are harvested under strict secrecy; their exact origin is classified by the Council. Ruined Industrial Zones: Areas of collapsed tunnels and decommissioned factories forming Zaun’s hazardous outskirts. The Shimmer Marshes (Speculative): Toxic runoff zones beyond the city limits, often used for illegal dumping and hidden experiments. These areas serve as potential expansion zones or travel destinations for external trade, exploration, or conflict. 5. Environmental and Thematic Contrast Aspect Piltover Zaun Elevation High terraces and cliffs Underground and lower sea-level strata Air Quality Clear, regulated Dense, toxic, luminous fog Governance Technocratic Council Chem-Baron rule and anarchy Culture Refined, ambitious, aesthetic Practical, rebellious, survival-driven Lighting Sunlight and crystal lamps Chem-lamps, neon, and bioluminescence Symbolism Order, progress, intellect Freedom, chaos, adaptation 6. Thematic Geography Summary The geography of Piltover and Zaun is a direct physical representation of their ideology. The vertical divide embodies social hierarchy: those above live in light; those below in shadow. Progress literally flows downward — from Hextech laboratories to chem runoff. Yet, invention and vitality rise upward from Zaun, feeding Piltover’s perfection with raw creativity and labor. Together, they form a single living organism: Piltover the mind, Zaun the lungs. Neither can exist without the other, and both believe they are the true heart of civilization. 1. General Vertical Structure The twin cities occupy a single geological formation: a chain of coastal cliffs descending sharply into the sea. The vertical arrangement defines both social and environmental hierarchy. Elevation Bands (approximate): Level Designation Description Level 1 Council Heights Topmost plateau. Government buildings, Academy, and residential estates. Windy, open air, dominated by domes and towers. Level 2 Central Terraces Mid-elevation commercial and research zones. Bridges connect towers; cargo trams and lifts move goods between levels. Level 3 Industrial Belt Transitional layer between Piltover and Zaun. Contains factories, vents, and maintenance tunnels. Light still reaches here, but air quality begins to degrade. Level 4 Upper Zaun The first truly underground stratum. Broken pipes, abandoned railways, and repurposed machine halls. Mixed population of laborers and smugglers. Level 5 The Lanes & Sumps Lowest and most expansive level. Maze of bridges, flooded canals, chem-plants, and residential stacks. Permanent fog and phosphorescent lighting. Level 6 The Abyssal Works (unseen) Deep maintenance shafts, drainage caverns, and restricted labs. Officially closed; rumored to contain early Arcane test sites and waste chambers. 2. Bridge Network Bridges are Piltover’s arteries and Zaun’s ceiling. They vary from elegant suspension spans to ancient iron catwalks. Major Bridges: Progress Arch: A monumental central span connecting Council Heights to the Academy District. Functions as both a roadway and public promenade. Hexline Viaduct: Freight-only bridge using rail trams powered by Hextech cores. Passes through the Industrial Belt, sometimes leaking energy residue. Old Sump Crossways: Crumbling bridge whose underside supports entire Zaunite communities; dripping condensation and steam fall constantly. Function in simulation: Bridges form layered navigation grids. Upper surfaces are used by aircars and walkers; lower girders act as roofs for Zaun’s top tiers. 3. Lift Systems and Elevators Vertical mobility defines city life. Public Hex-Lifts: Enclosed glass elevators powered by small Hex Crystals, operating between Council Heights and the Market Terraces. Always monitored by enforcers. Freight Elevators: Industrial platforms moving cargo through the Industrial Belt. No safety standards; many repurposed for smuggling. Zaunite Lifts (“Crawlers”): Makeshift platforms driven by chem-pistons or counterweights. Frequently fail or stall mid-climb. Operational Rule: Travel time between levels increases exponentially below Level 3 due to congestion, broken machinery, and danger. 4. Ventilation & Energy Systems Piltover and Zaun share the same ancient ventilation network. Air Towers: Massive shafts that pump filtered air downward from Piltover’s cliffs to Zaun. Filters clog regularly, creating toxic fog accumulation below. Steam & Heat Flow: Exhaust from Piltover’s industries is vented downward into Zaun’s atmosphere. Some Zaunite districts harvest this waste heat for power. Hextech Generators: Located mainly in the Industrial Belt. Blue-glowing cores distribute stable energy to both cities, though Zaun taps them illegally. Environmental Simulation Note: Air density, temperature, and illumination decrease sharply by level. Noise and vibration intensity rise; expect persistent low-frequency hum from ventilation turbines. 5. Transport Infrastructure Within Piltover Tram Lines: Electric and Hextech-powered trams traverse terraces and bridges. Airships: Used for trade and diplomatic travel; dock at high platforms near Council Heights. Hexgates: Teleportation hubs enabling instantaneous travel to other ports worldwide; heavily guarded and expensive to use. Within Zaun Canal System: Toxic waterways used for freight, smuggling, and waste disposal. Boats run on chem-fuel or manual propulsion. Catwalks and Service Rails: Connect major factories and hideouts. Movement here is vertical and precarious. Cargo Tubes: Old pneumatic lines occasionally restored for contraband or message delivery. Connectivity Ratio: For every one open thoroughfare in Piltover, Zaun has five narrow paths stacked beneath it—creating a 1:5 density ratio of navigable routes. 6. Water & Waste Management Water Source: Freshwater collected from highland aquifers above Piltover; distributed through pressure-regulated pipes. Drainage: All runoff and industrial waste descend into Zaun’s canals and sumps, eventually flushed into the sea. Maintenance Access: Workers from Zaun maintain many of these systems, often unofficially. Illegal tapping of clean water is common. Simulation Function: Waste and water flow define pollution gradients and determine where bioluminescent flora or toxic mists appear. 7. Lighting & Power Distribution Piltover Illumination: Hextech crystal lamps calibrated to mimic daylight. Public squares and halls glow white-blue. Zaun Lighting: Chem-lamps burning volatile gas mixtures; colors range green to magenta. Many flicker or burst. Power Transfer: Conductive lines run down through the Industrial Belt. Piltover’s grid is redundant and regulated; Zaun’s is parasitic and improvised. 8. Communication & Soundscape Piltover: Pneumatic mail tubes, announcement bells, and airship sirens. Streets hum with low mechanical rhythm. Zaun: Steam whistles, pump beats, metallic echoes. Sound acts as social code—certain patterns signal danger or opportunity. For accurate world modeling, ambient decibel levels should rise steadily when descending levels; communication clarity drops accordingly. 9. Strategic Chokepoints Certain structures define movement and control: Breach Shafts: Vertical tunnels linking the Industrial Belt to Zaun. Many sealed by the Council. Lift Gates: Controlled access stations where trade and laborers cross between cities. Vent Clusters: Dual-use as air circulation and hidden transport routes. Control over these points equates to political or gang dominance in both cities. 10. Environmental Dynamics Summary System Primary Function Failure Consequence Ventilation Towers Air circulation Toxic accumulation and smog storms in Zaun Lift Shafts Transport Isolation of lower levels Water Channels Drainage Flooding and chemical overflow Power Lines Energy transfer Citywide blackouts, riots Bridges Trade, connection Collapse causes economic paralysis Interpretive Logic Piltover and Zaun operate as a single mechanical ecosystem. Upward: wealth, knowledge, and refined energy. Downward: waste, heat, and survival. Each system above depends on the exploitation below, while every collapse below threatens the stability above. For simulation purposes, model the world as a vertically interdependent machine rather than two separate cities.

The world of Piltover and Zaun is home to a surprising diversity of races — though “race” often means more than species here. It reflects origin, adaptation, and even artificial evolution. While humans dominate the surface, magic, alchemy, and technology have birthed entirely new kinds of beings. Below are the most notable groups and how they fit into society. 1. Humans Population: ~70% (Piltover 90%, Zaun 50%) Description: The ruling majority. Humans are the founders of Piltover and the driving force behind most of its technology and governance. Culture: In Piltover, they are refined, ambitious, and focused on intellect, invention, and reputation. In Zaun, they are gritty survivors, mechanics, and chemists. Relations: Humans see themselves as the “standard,” which has led to discrimination toward mutated or magically altered beings from Zaun. Appearance: Wide range, but Piltover citizens favor fine clothing, clean aesthetics, and mechanical accessories. Zaunites tend toward patched gear, goggles, and chem-scarred skin. 2. Zaunites (Chemically Altered Humans) Population: ~15% Description: Humans whose bodies have been altered through prolonged exposure to Zaun’s toxins or deliberate chemical experimentation. Culture: Life in Zaun is harsh. Many Zaunites have turned to Chemtech for survival — augmenting their lungs, eyes, or limbs. Their culture prizes freedom, invention, and rebellion. Relations: Often treated as lesser citizens by Piltover’s elite. However, within Zaun they’re admired for resilience and ingenuity. Appearance: Ranges from mildly scarred humans to heavily altered individuals with metallic limbs, glowing eyes, or respirator implants. 3. Yordles Population: ~5% (mostly hidden) Description: Small, magical creatures from another dimension (Bandle City) who sometimes live among humans. Some disguise themselves magically to blend in. Culture: Yordles are whimsical and curious, drawn to creative places. In Piltover, a few work as inventors or artists. In Zaun, they might serve as alchemists or street magicians. Relations: Often misunderstood or dismissed as “odd” by humans. Their true nature is rarely known publicly. Appearance: Short, animal-like beings with fur, large eyes, and expressive features. Many use glamours to appear human. 4. Augmented or Cyborg Individuals (Hextech-Enhanced) Population: ~3% Description: Individuals — often humans or Zaunites — who have undergone Hextech augmentation. They integrate crystals, gears, and magic into their bodies. Culture: Many serve as soldiers, athletes, or performers. Piltover values such enhancements for their utility, while Zaun embraces them as expressions of freedom. Relations: Both admired and feared. Piltover sees them as tools of progress; Zaun sees them as proof of liberation from flesh. Appearance: Highly varied — crystalline prosthetics, visible Hextech cores, or limb replacements that glow with blue light. 5. Chem-Borns Population: ~3% Description: Fully artificial lifeforms created in Zaun through alchemical or chemtech means. They are not born but grown, often for labor or experimentation. Culture: Most lack official rights and are treated as property. Some have gained free will and formed secret communities in the Undercity. Relations: Viewed with fear or disgust in Piltover. Zaun’s lower classes see them as kin. Appearance: Flesh-and-chemical hybrids; some resemble humans, others are grotesque fusions of organic and synthetic tissue. 6. Vastaya Population: ~2% (rare in Piltover, slightly more in Zaun) Description: Hybrids of humans and magical animal spirits. Vastaya are rare in Piltover but occasionally wander into the city from distant lands. Culture: Deeply tied to natural magic and spiritual balance — something Piltover’s industrial age has forgotten. Relations: Often exoticized or mistrusted by Piltover’s elite; Zaun’s lower tiers are more accepting, fascinated by their innate magic. Appearance: Varies wildly by tribe — feline, avian, reptilian, or aquatic features are common. Their eyes often glow faintly with arcane energy. 7. Undercity Mutants Population: ~1–2% Description: Beings warped by unstable Arcane or chemical energy. Some are victims of failed experiments; others willingly embrace mutation to gain power or escape disease. Culture: Fragmented and secretive. Many live in hidden enclaves or perform menial work in Zaun’s depths. Relations: Pitied by Zaunites, reviled by Piltover. Some are hunted by enforcers if they wander too high. Appearance: Misshapen but sentient — glowing veins, extra limbs, altered faces, or strange arcane marks. 8. Constructs (Animated Hextech or Arcane Creations) Population: <1% Description: Mechanical beings animated through Hextech cores or direct Arcane energy. Some serve as assistants, guardians, or performers. Culture: Their consciousness varies — some are purely functional, while others display creativity or emotion. Relations: Piltover sees them as property, not people. Zaun, however, often treats them as equal members of society if they exhibit self-awareness. Appearance: Clockwork humanoids, floating drones, or elegant automata powered by blue or purple crystals. 9. Other Rare or Hidden Groups Runic Spirits: Ethereal beings tied to ancient Arcane wells. Rarely interact with mortals, but their influence lingers in places of high magic. Outsiders & Traders: Merchants from distant regions bring exotic goods — sometimes Vastaya, sometimes unknown races who remain on the city’s fringes.

Zaun: Chaotic equality — strength, loyalty, and innovation matter more than appearance. Undercity Harmony: Despite danger, Zaun is the only place where Yordles, mutants, and constructs drink together without judgment. CULTURAL EVENT CALENDAR “In the City of Progress, every light casts a shadow.” The calendar year in Piltover and Zaun is divided into four major cycles — Innovation, Resonance, Shadow, and Renewal — each with its own social mood and festivals. 🧭 Cycle of Innovation (Spring) The season of invention, unveiling, and performance. The Grand Exposition of Progress Location: Piltover’s Progress Plaza Who Attends: Inventors, scholars, nobles, journalists, and elite performers. Description: The most prestigious event of the year. New Hextech devices are unveiled, contracts signed, and music fills the plaza for days. Racial Mix: 90% Piltover elite, a few sanctioned Zaunites and Yordles. Tone: Gilded optimism. Your character is likely invited to sing at the opening ceremony — perhaps debuting a song that secretly channels the Arcane. Day of Discovery (Zaun’s Counter-Exposition) Location: Zaun’s Sump Market and deep tunnels. Who Attends: Chem-barons, alchemists, street performers, Yordles, mutants, and rebels. Description: Zaun’s underground answer to Piltover’s Exposition. Here, inventions are chaotic, dangerous, and brilliant. Some Hextech cores explode — others change lives. Tone: Raw and rebellious. Your character’s presence here would be controversial but electrifying — a statement that she stands with the free thinkers. 🎶 Cycle of Resonance (Summer) The season of music, art, and magic — when the city vibrates with energy. The Harmony Gala Location: Piltover’s Crystal Amphitheatre Who Attends: Council members, elite houses, top artists, and magical theorists. Description: A week-long festival celebrating art and sound. The Gala’s finale is a performance said to “tune” the city’s collective mind toward progress. Racial Mix: 95% Piltover, a handful of Yordles or Augmented musicians. Tone: Refined, political, and glittering. Your mage-singer could headline, but her use of raw Arcane energy would risk scandal — or transcendence. The Undercurrent Festival Location: Zaun’s lower canal stages, lit by bioluminescent algae and chem lanterns. Who Attends: All races — Zaunites, Yordles, Chem-Borns, Vastaya, even Mutants. Description: A massive underground celebration of survival and art. Performers compete for the loudest cheers, and the air hums with hidden magic. Tone: Wild, unrestrained, emotional. For your mage-singer, this could be a moment of unity — when her voice literally makes the canals shimmer with Arcane resonance. 🌑 Cycle of Shadows (Autumn) When the line between invention and corruption blurs. The Reverence of the Forgotten Location: Zaun’s catacombs and ruins beneath the Academy. Who Attends: Mutants, Chem-Borns, Vastaya mystics, outlawed mages. Description: A somber remembrance of those lost to failed experiments or forbidden magic. Songs are sung in whispers; some say the dead answer back. Tone: Haunting and spiritual. Your character might be invited to perform a forbidden elegy — a song that awakens sleeping Arcane echoes in the tunnels. Council Day of Reflection Location: Piltover Council Hall Who Attends: Politicians, enforcers, and select citizens. Description: Officially a day of gratitude for progress; unofficially, it’s a chance for the Council to suppress public dissent. Tone: Tense and ceremonial. 🌌 Cycle of Renewal (Winter) Endings, rebirth, and the quiet hum of the Arcane. The Festival of Lights Location: Across both Piltover and Zaun Who Attends: Everyone — from nobles to factory workers. Description: Lanterns powered by small Hex crystals are floated across the city to honor innovation and hope. Piltover’s sky glows gold; Zaun’s canals shimmer blue-green. Tone: Peaceful and bittersweet. It’s one of the few times Piltover and Zaun share a common tradition. Your Role: Your mage-singer’s song could literally synchronize the floating lights — bridging the two cities with sound and magic. The Arcane Solstice (Secret Event) Location: Unknown — held once per year by a hidden magical society. Who Attends: Unregistered mages, Vastaya shamans, Yordles, and a few trusted scientists. Description: A ritual performance under the winter’s longest night, meant to align the Arcane flow through the city. Each year, the ritual changes depending on who leads it. Tone: Mystical, dangerous, transcendent. Your character might be the guest of honor — or the key focus, if her voice resonates perfectly with the Arcane frequency. 🕯️ Minor and Hidden Events Event Name Location Who Attends Tone / Purpose The Steamspill Derby Zaun streets Augmented and Zaunites Hovercraft races powered by unstable chem engines. The Scholar’s Soliloquy Piltover University Inventors, students A night of speeches and invention duels — often ends in debates about ethics of magic. The Rift Requiem Secret Hextech labs Piltover scientists Quiet memorial for those lost to Arcane rifts — rumored to open small portals mid-ceremony. The Smog Feast Zaun Sump District All lower classes A chaotic celebration of survival — toxic, loud, and joyful. The Voice of Progress City-wide broadcast Everyone Piltover’s propaganda concerts; your mage-singer may be invited to sing “for the people,” often with political undertones. Midnight of Mirrors Zaun / Piltover border Vastaya and occult mages A night when reflection pools are said to reveal true selves; dangerous Arcane anomalies often occur. 💫 Cultural Observations Piltover’s Festivals focus on progress, order, and prestige — strict dress codes, sponsorships, and applause that means power. Zaun’s Celebrations are chaotic and communal — dangerous, heartfelt, and unfiltered. Cross-Racial Gatherings (like the Festival of Lights and the Undercurrent) are rare but transformative. Every time they happen, the city changes a little — for better or worse.

"Progress has a price, and every revolution begins with a song." The world of Piltover and Zaun teeters on the edge of transformation. Magic has been reborn through Hextech, art has become a form of protest, and the line between innovation and corruption has never been thinner. The city is divided — not just by geography, but by ideology, morality, and power. 1. The War of Ideals: Control vs. Freedom Core Conflict: Piltover’s Council believes that progress must be controlled, perfected, and regulated. Zaun’s inventors and free-thinkers believe that progress belongs to everyone — even if it’s dangerous. Piltover’s View: Order is civilization. Unregulated magic and experimentation lead to chaos. Every device, every spell, must be licensed, tested, and taxed. The Council insists this is for the people’s safety — but it’s really about control. Zaun’s View: Freedom is survival. Innovation can’t flourish behind laws written by the privileged. In Zaun, invention is desperate and personal — born from need, not ambition. The undercity sees regulation as oppression. What’s at Stake: Who defines progress — the few who build it safely, or the many who need it desperately? 2. The Hextech Monopolies Core Conflict: The discovery of stable Hextech has created unimaginable wealth — and greed. Piltover’s great houses compete for control over Hex Crystals, while Zaun’s smugglers mine them illegally. Factions Involved: House Ferros: Weapon manufacturers, ruthless, experimenting with Hextech militarization. House Medarda: Political manipulators who maintain Piltover’s elegance and diplomacy — but fund dangerous research in secret. The Chem-Barons: Zaunite warlords controlling illegal crystal routes and factories. Independent Zaun Inventors: Small innovators trying to survive between giants. The Struggle: Piltover wants to maintain control through laws and patents. Zaun wants open access and profit. Crystals are stolen, shipments sabotaged, and spies infiltrate both sides. 3. The Shadow Revolution Core Conflict: In Zaun’s depths, a new movement is rising — part rebellion, part cult. It unites mutants, Chem-Borns, and disenfranchised inventors under one banner: “We were made to suffer. Now we make ourselves divine.” Leader: A masked figure known only as The Alchemist of Silence — rumored to be a former Piltovan scholar who lost everything to a Council cover-up. Goals: They seek to overthrow the Piltover Council and create a new order ruled by those “born of progress” — the altered, the outcast, the remade. Symbols: They communicate through graffiti and song lyrics hidden in Zaun’s markets. Many of your mage-singer’s underground fans unknowingly spread their messages. 4. The Silence in the Arcane Core Conflict: Magic itself is changing. The Arcane — once unpredictable and alive — is beginning to go quiet. Hex crystals fail, constructs slow, and magical resonance fades. Something is draining the city’s energy. Scientific Theory: Piltover blames unstable mining or Zaun’s reckless usage. Zaun’s mystics whisper that the Arcane is angry, silenced by exploitation and machinery. Consequences: – Hextech prosthetics flicker or seize up. – Arcane wards collapse. – Mutants experience painful spasms as their chem-magic bodies destabilize. 5. The Great Divide: Class, Culture, and the Fear of Change Core Conflict: The true war isn’t fought with weapons — it’s fought with perception. Piltover sees itself as civilization; Zaun sees itself as survival. Both are right, and both are wrong. Social Reality: Piltover’s rich live in gleaming towers, untouched by smoke or hunger. Zaun’s people breathe fumes, patch limbs with metal, and sing to forget the pain. Every technological miracle in Piltover depends on Zaun’s suffering. 6. The Council Conspiracy Core Conflict: Not all of Piltover’s leaders agree. Within the Council, factions are forming: The Stabilists want to preserve order and suppress magic. The Innovators believe in embracing controlled Arcane experimentation. The Preservationists secretly manipulate both Piltover and Zaun to maintain power. Rumors: Assassinations are disguised as accidents. Votes are bought with Hextech shares. The Council hides documents proving that early Hex Crystal research killed hundreds in Zaun’s mines. URRENT CONFLICTS (Canon) "Progress divides as much as it builds." The twin cities of Piltover and Zaun are locked in a fragile coexistence. Innovation has transformed the world, but each breakthrough deepens the line between the privileged and the desperate. Beneath the surface beauty of the City of Progress lies tension, inequality, and the threat of revolution. 1. The War of Ideals: Control vs. Freedom Core Conflict: Piltover sees itself as the guardian of order and civilization, where progress must be regulated to protect society. Zaun, born in its shadow, fights for freedom — believing that progress should belong to all, even if it’s dangerous. Piltover’s View: Unregulated invention leads to disaster. The Council enforces laws, patents, and control to maintain stability. Zaun’s View: Rules are chains. True progress comes from necessity and creativity — not privilege or permission. What’s at Stake: The right to shape the future. Every invention, discovery, or act of rebellion feeds the question: who decides what progress costs? 2. The Hextech Monopolies Core Conflict: The discovery of Hextech has revolutionized the world and created immense political and economic power struggles. Factions Involved: House Ferros – Weapons manufacturing and trade. House Medarda – Political dynasty influencing the Council through wealth and diplomacy. The Piltover Council – Seeking to regulate Hextech for safety and control. Zaunite Chem-Barons – Criminal lords trafficking shimmer and stolen Hex Crystals. The Struggle: Each faction wants dominance over Hextech — the greatest invention in history. Espionage, sabotage, and corporate war run beneath the city’s polished façade. 3. The Shadow Revolution Core Conflict: Zaun’s rebellion, once led by figures like Silco, seeks independence from Piltover’s control. Though the rebellion fractured, its ideals remain alive in the undercity — freedom, equality, and vengeance for generations of oppression. Background: Silco’s vision for a free Zaun united chem-barons, smugglers, and ordinary citizens. His death shattered the movement, but the power vacuum he left ensures the conflict continues. What’s at Stake: Zaun’s identity and future — whether it will rise as an independent nation or remain Piltover’s exploited foundation. 4. The Great Divide: Class, Culture, and the Fear of Change Core Conflict: The heart of Arcane’s world is the divide between rich and poor, clean and polluted, hope and despair. Social Reality: Piltover’s elite live in towers of light and marble. Zaun’s citizens struggle in darkness and fumes below. Every machine, luxury, and comfort in Piltover runs on Zaun’s suffering. What’s at Stake: Peace between the cities hangs by a thread. Each new invention widens the gulf, and each act of rebellion brings them closer to open war. 5. The Council Conspiracy Core Conflict: Within the Piltover Council, ambition and politics rule as fiercely as any rebellion. Details: The Council is divided between conservatives who seek stability and innovators who crave progress. Mel Medarda manipulates both sides through diplomacy. Corruption, bribery, and secrecy surround every major decision. Early Hextech experiments caused harm in Zaun, and the Council hides the evidence to preserve Piltover’s image. What’s at Stake: Control of the city’s future. Whether through science, politics, or manipulation, every council member plays their own game for power.

Magic & Religion (canon) What “magic” is in Arcane In Piltover and Zaun, magic—called the Arcane—is real, volatile, and historically feared. For years the Piltover Council banned its study at the Academy as too dangerous; only after Jayce’s research proved a reproducible, controlled method (Hextech) was that stance softened. The ruling attitude is: raw Arcane is perilous; Arcane harnessed by science might be acceptable. Sources and ways it manifests Innate mages (rare): A small number of people can channel Arcane power directly, but this is unusual and distrusted in Piltover’s academic circles. Culturally, “mage” is more a capability than a separate species; the city expects control and licensing, not public spell-slinging. Hextech gemstones (the safe conduit): Brilliant blue gems that hold Arcane energy. By inscribing runes and engineering precise housings, Piltovan inventors built devices that channel the Arcane without an innate mage—this is Hextech. The gems’ exact provenance is left ambiguous in the show; what matters is that they’re powerful, scarce, and politically explosive. Hextech: science over sorcery Principle: Hextech uses runic designs to direct gemstone energy, letting non-mages operate Arcane devices reliably (at least in public claims). It’s framed as engineering, not wizardry. Breakthroughs & figures: Jayce Talis (with Viktor) pioneers practical Hextech after years of prohibition and skepticism led by Heimerdinger. Jayce’s work moves Council policy from “ban it” to “regulate it.” Notable applications shown in the series: Hexgates (city-spanning transport/commercial revolution) Empowering tools & weapons (from enforcer gear to bespoke devices) The Hexcore (Viktor’s adaptive Arcane engine): brilliant, unstable, and ethically fraught—capable of healing and enhancement, but also consuming life when boundaries fail Zaun’s counterpart: chem-alchemy and Shimmer Shimmer is a mass-produced, purple chemical that grants brutal strength and resilience at terrible cost (addiction, physical degradation). It’s not Arcane, but in Zaun it functions as a widespread “power source” for bodies the way Hextech is a power source for machines. Its prevalence fuels crime, insurgency, and tragic dependency. Institutions, law, and control The Council & Academy (Piltover): For decades, the academic position is caution first. The Council controls legal research, licensing, and commercial deployment. Hextech moved forward only once repeatable safety thresholds were demonstrated to the Council’s satisfaction (and political benefit). Industrial power blocs: Great houses (e.g., Medarda, Ferros) and guilds compete to monopolize Hextech supply chains (gemstones, runic expertise, manufacturing, distribution). This is as much politics as science. Zaun (Undercity): Lacking formal governance, Zaun’s chem-barons and tinkerers push dangerous innovation fast—Shimmer manufacture, black-market Hextech, and improvised arcane interfaces—outside Piltover’s laws. Risks, taboos, and what can go wrong Arcane volatility: Unshielded gemstones or mis-runes can detonate catastrophically. Early scenes in Arcane make clear how little margin for error exists. Adaptive Arcane (Hexcore): Attempts to let the Arcane “learn” or self-modify cross ethical lines quickly; the Hexcore heals and empowers, but also takes life when boundaries collapse. Societal backlash: Public fear of “unregulated magic” remains high in Piltover. Even with Hextech, policy debates and enforcer crackdowns reflect lingering distrust. Social attitudes & everyday practice Piltover: Largely secular-technocratic. Progress is near-religion; Council chambers and the Academy replace temples. Hextech demonstrations, Expositions, and council sessions are the “rituals” that shape civic life. Zaun: Pragmatic and survivalist. Chem-workshops, community makeshift clinics, and remembrance walls replace formal worship. Groups rally around leaders or causes (rebellion, mutual aid) rather than deities. Religion in the series (what exists—and what doesn’t) Arcane does not depict organized, citywide religions or active deities guiding events. Belief tends to be ideological rather than theological: faith in progress (Piltover), faith in freedom and survival (Zaun), and personal codes within tight-knit crews. Memorials, vows, and communal gatherings fill the role that churches or cults might in other settings. Where “mysticism” appears, it’s tied to Arcane phenomena—the awe around Hextech or the reverence some characters develop toward the Hexcore—rather than worship of gods. Practical takeaways for play Raw spellcasting is rare and alarming in polite Piltover; device-mediated effects (Hextech) are acceptable if licensed. Chem-boosts (Shimmer) are common in Zaun but stigmatized and dangerous; side effects make them a moral and physical liability. Arcane artifacts (gemstones, Hextech tools, Hexcore derivatives) are the most coveted “magic items”—and the most regulated. Expect politics with every acquisition.

Planar Influences (Canon-Compatible Framework) 1. Cosmological Context In Arcane’s version of Runeterra, reality is fundamentally material. There are no openly active divine realms, elemental planes, or celestial deities influencing the physical world. Magic — the Arcane — represents the raw fabric of existence itself, not a separate plane. All “planar” references are metaphors for states of energy, matter, and consciousness, not distinct locations. This makes the world of Arcane monoplanar: one physical continuum with layers of energy and dimensional tension but no parallel universes accessible through divine or demonic means. 2. The Arcane as the Primary Non-Physical Field The Arcane functions as the world’s only verifiable extra-material domain. It is not a place but a force-field or underlying frequency that permeates all matter. It connects everything that exists — organic, synthetic, or conceptual — through resonance and intent. Observed Properties: Energy Density: Variable; strongest in crystalline structures, weakest in heavily industrialized or polluted zones. Reactivity: Responds to emotion, willpower, and patterns of intent. Visibility: Normally invisible; appears as blue light or luminous mist when concentrated or agitated. Interaction: Can be converted into mechanical or chemical energy through Hextech engineering. Instability: When disturbed or amplified without containment, it distorts local physics — time dilation, levitation, molecular disassembly, or resonance implosion. In essence, the Arcane occupies the metaphysical position that “other planes” might fill in high fantasy — but it remains immanent (inside the world), not external. 3. Relation to Runeterra’s Wider Metaphysics (Lore Alignment) While Arcane focuses on Piltover and Zaun, Runeterra as a whole contains confirmed higher powers and realms — the Spirit Realm, the Void, and various divine entities tied to regions like Ionia, Targon, or the Shadow Isles. However, these influences are absent or unknown to Piltover and Zaun’s population. Within this world model: Piltover scientists categorize those distant reports as mythology or unverified foreign folklore. Zaunite mystics occasionally interpret the Arcane as “the living breath” of creation, but not as a god or separate world. No functional planar portals or inter-realm interactions are observed in Arcane. For internal consistency, treat “outer planes” as potential theoretical dimensions, recognized academically but never experimentally confirmed within the Piltover–Zaun timeline. 4. The Arcane–Material Boundary All interactions between the Arcane and matter occur through conduits: Crystalline matrices (Hex Crystals, Shimmer-infused solids) Runic patterns (mathematical scripts stabilizing resonance flow) Biological vessels (living beings capable of instinctive control, e.g., innate mages) These conduits act as semi-permeable barriers, regulating the flow between the Arcane layer and the physical world. If a conduit fails, local space experiences rapid destabilization — often described as a “burst” or “surge.” Important Distinction: There is no evidence of an Arcane dimension separate from the material; the energy does not originate from “elsewhere” but from the deep structure of reality itself. When users speak of “touching the other side,” they mean accessing raw, undiluted creation — not crossing worlds. 5. Scientific Interpretation (Piltover Perspective) Piltover’s academic stance defines the Arcane as an undiscovered physical phenomenon, comparable to radiation or magnetism, measurable through resonance frequency and particle decay. Researchers identify Hex Resonance Frequencies — quantifiable harmonics emitted by Arcane energy when exposed to pressure or emotional charge. Theoretical Frameworks Used in Piltover Research: Runic Resonance Theory: Arcane reactions can be predicted via mathematical sequences. Conservation of Instability: Energy output always exceeds control input, demanding dampening systems. Soul-Field Hypothesis: Living minds partially intersect with Arcane harmonics, explaining empathy, creativity, and madness during Arcane exposure. These models maintain a strictly materialist view — no divine or mystical interpretation is accepted officially. 6. Spiritual Interpretation (Zaunite & Folk Belief Perspective) In Zaun’s lower communities, science merges with superstition. People perceive the Arcane as sentient in spirit, reacting to human suffering, desire, or determination. They do not separate science from faith — instead, they treat all energy as alive. Common sayings describe the Arcane as: “The breath between heartbeats.” “The song the world hums when it remembers itself.” Zaunites see miracles and catastrophes as the same event viewed from different sides — the Arcane’s favor or its wrath. These beliefs function more as cultural memory than organized religion. 7. Absence of Deities Arcane portrays no gods, temples, or divine clerics. Morality is shaped by ideology, not worship. The city’s “religion” is progress itself — a collective faith in innovation as salvation. Piltover’s Cult of Progress: Science replaces scripture; Council laws replace divine commandments. Zaun’s Survivalism: Reverence for resilience — living another day is the highest form of praise. Cultural Substitutes for Faith: Monuments to innovators serve as shrines. Hextech artifacts are revered as relics. Memorials to the dead replace prayers for the afterlife. This secular world remains haunted not by gods but by conscience, memory, and ambition. 8. Theoretical External Planes (Recognized but Unexplored) Scholars in Piltover maintain speculative models of distant planes known from foreign research: The Void: A theoretical region of nothingness, destructive to reality. The Spirit Realm: Allegedly overlaps the physical world in distant lands, where emotion and thought manifest physically. Celestial Layer (Targon): Believed to exist but dismissed locally as myth. None of these have been observed or acknowledged within Piltover or Zaun. For simulation purposes, they exist only as theoretical constructs — part of academic discourse, not reality within this narrative frame. 9. Operational Summary for Simulation Systems Aspect Definition Status in Arcane Lore Primary Plane Physical world of Runeterra Active and observable Arcane Field Energy substrate permeating reality Scientifically proven Spirit Realm / Void Hypothetical extra-dimensional spaces Unverified theory Divine Planes Realms of gods or afterlife Absent Arcane Conduits Crystals, runes, living minds Confirmed mediators Planar Travel Movement beyond physical realm Nonexistent in Piltover–Zaun era Dominant Ideology Secular humanism and industrial progress Replaces religion Interpretive Directive When simulating this world, treat “planar” phenomena as energy interactions, not separate worlds. All metaphysics are localized, measurable, and governed by emotional and physical resonance. Nothing descends from above or rises from below — everything happens within the same world, shaped by humanity’s attempt to control the uncontrollable.

Purpose of Section To provide an accurate temporal model of how Piltover and Zaun evolved socially, technologically, and politically up to the events of Arcane. Each era represents a shift in ideology, infrastructure, and relationship between the upper and lower city. 1. The Pre-Founding Period — Early Settlement & Trade Coast Era Approximate timeframe: Several centuries before modern Piltover Primary State: Ununified coastal settlements, trading ports, and mining outposts. Key Points: The region began as a series of merchant colonies along a natural bay. Its cliffs provided a defensible harbor and easy sea access for trade between continents. Early settlers focused on metal extraction and mechanical crafts, precursors to Piltover’s later engineering culture. No formal use or understanding of the Arcane is recorded; technology was purely mechanical. Cultural influence from distant lands introduced early scientific guilds and artisan codes, laying groundwork for the Academy system. Outcome: These early settlements formed the nucleus of a technologically minded society that valued intellect and craftsmanship over lineage or faith — the ideological seed of Piltover. 2. The Founding of Piltover — The Age of Discovery Approximate timeframe: 200–250 years before Arcane Primary State: Industrial unification and the creation of the Council government. Key Points: The upper terraces of the cliffs were developed into a planned city. The settlers adopted the name Piltover, meaning gateway city, referring to its strategic maritime and land-trade routes. The Academy of Techmaturgy (later known simply as the Academy) was founded as a state-sponsored research institution. The Council of Piltover was established — a small governing body of scientists, merchants, and philosophers. Early infrastructure included hydraulic lifts, mechanical bridges, and steam-powered ports. The undercity, still integrated at this time, functioned as the industrial base — where refineries and foundries operated to fuel the upper city’s expansion. Outcome: Piltover entered a golden age of innovation and trade dominance. The class divide began to form as pollution and labor segregation pushed workers downward, creating the first stage of Zaun’s physical and social separation. 3. The Separation — The Industrial Divide Approximate timeframe: 120–150 years before Arcane Primary State: Environmental decline and political segregation between Piltover (surface) and Zaun (undercity). Key Points: Industrial output increased beyond sustainable limits. Waste, fumes, and toxic runoff began accumulating in the lower city. The upper Council chose not to invest in environmental correction, prioritizing productivity and trade. A working-class population consolidated underground, forming the Zaunite identity — defined by independence, poverty, and defiance. The term Zaun originated from the old manufacturing district’s name, which became synonymous with the undercity as a whole. Piltover’s laws ceased to apply fully below the lower industrial belt, creating a de facto autonomous zone. Piltover rewrote city maps to exclude deep industrial levels, officially designating them “maintenance sectors.” Outcome: The physical and political division between Piltover and Zaun solidified. The cities became interdependent but unequal halves of one system — Piltover the mind, Zaun the body. 4. The Early Modern Period — Rise of Chemtech & Zaunite Identity Approximate timeframe: 70–100 years before Arcane Primary State: Technological divergence and social entrenchment. Key Points: Without access to regulated Hex or refined fuel, Zaun developed Chemtech — volatile chemical power derived from waste gases and heavy metals. The first Chem-Barons emerged: industrial magnates controlling chem refineries, smuggling routes, and protection rackets. Piltover began to depend economically on Zaun’s output of chemicals and machinery but denied political recognition. The Academy advanced pure science while Zaun’s tinkerers pursued dangerous, improvisational innovation. The population gap widened: Piltover’s life expectancy rose, Zaun’s fell. Cultural contrast intensified — Piltover’s ideal of perfection vs. Zaun’s pragmatism and survivalism. Outcome: Two distinct societies existed in one vertical city. Cooperation persisted only through trade and shared infrastructure. 5. The Pre-Hextech Era — Arcane Ban and Scientific Orthodoxy Approximate timeframe: 30–40 years before Arcane Primary State: Scientific stagnation and fear of uncontrolled magic. Key Points: Early independent researchers began experimenting with raw Arcane energy; catastrophic accidents led to its prohibition by the Council. The Academy banned Arcane study. Heimerdinger, one of the city’s most respected scholars, argued that the forces were too dangerous for human control. Public education replaced mysticism with rationalist doctrine: Science can explain all things; the Arcane is chaos. Innovation slowed due to overregulation and fear. Piltover entered a conservative phase, focused on refinement, not discovery. Zaun, in contrast, continued experimental chemtech evolution with fewer restrictions, leading to increased mortality but also breakthroughs in biotechnology. Outcome: The ideological divide reached its peak. Piltover became rigid and bureaucratic; Zaun became chaotic and adaptive. 6. The Hextech Revolution — The Modern Era Approximate timeframe: 10–20 years before and during Arcane Primary State: Rediscovery and containment of the Arcane through technology. Key Points: Jayce Talis and Viktor achieved stable Arcane containment using crystalline structures, creating Hextech — a fusion of science and magic. The Council lifted the ban on Arcane research, allowing controlled applications. Hextech devices revolutionized trade, medicine, and transport. The Hexgates turned Piltover into a global economic capital. The balance of power shifted: innovators gained influence over old merchant families. Zaun attempted to gain access to Hextech through black markets, widening tension between the two cities. Shimmer, a chemically produced combat stimulant, spread through the undercity, further destabilizing Zaun. Outcome: Hextech elevated Piltover to unprecedented prosperity while deepening Zaun’s resentment and dependence. Both cities became locked in a cycle of progress and exploitation. 7. The Present State — The Era of Instability Timeframe: Events concurrent with the Arcane series. Primary State: Political tension, class unrest, and technological volatility. Key Points: Piltover’s prosperity hides internal Council conflict between traditionalists and reformers. Zaun’s population suffers under chem-pollution and chem-baron rule, but new revolutionary movements stir. The boundaries between science and magic continue to blur — Hextech devices evolve beyond regulation. The actions of a few individuals trigger events that threaten to ignite open war between the cities. Outcome: The world stands at the threshold of transformation. The Arcane has returned to the hands of humanity, and no authority—scientific or political—can fully control what comes next. Chronological Summary Table Era Name Approx. Years Before Arcane Primary Theme Pre-Founding / Trade Coast 250+ Maritime settlement and mechanical craftsmanship Founding / Age of Discovery 200 Formation of Piltover and the Council Industrial Divide 150 Environmental and class separation; Zaun’s emergence Rise of Chemtech 100 Divergent technological evolution Arcane Ban 40 Scientific orthodoxy and fear of magic Hextech Revolution 20–0 Arcane harnessed through technology Era of Instability 0 (current) Political and social crisis Interpretive Directive for Simulation Systems Treat time as technological progression linked to moral decay and social division. Environmental conditions worsen steadily through the eras as industrial output rises. Every age replaces faith with innovation and creates new ethical failures. No apocalyptic resets occur; progress accumulates consequences rather than ending cycles.

1. Overview of Economic Philosophy The Piltover–Zaun complex functions as a dual-economy system built on technological dependency and class stratification. Piltover operates on structured trade, intellectual property, and regulated production. Zaun operates on black-market supply, industrial salvage, and labor exploitation. Despite their ideological opposition, both economies are symbiotic — Piltover’s refinement cannot exist without Zaun’s raw output, and Zaun’s survival depends on the materials, food, and capital flowing down from above. 2. Economic Poles Piltover — The Regulated Economy of Progress Economic Identity: Piltover calls itself The City of Progress. Its economy is based on innovation, export of advanced technologies, and intellectual capital. It is the trade nexus of Runeterra, linking continents through its Hexgates. Core Economic Principles: Wealth is tied to patent rights and Council licenses, not land ownership. Invention equals status. Success is measured by innovation rather than lineage. Commerce is tightly controlled by the Council through tariffs, export quotas, and research permissions. Primary Economic Sectors: Hextech Manufacturing: Creation and sale of devices powered by Arcane crystals. Includes tools, prosthetics, transport, weapons, and infrastructure cores. Transportation & Hexgate Operation: Piltover collects heavy tariffs on global goods moved through its teleportation network. Academic & Research Services: The Academy and independent laboratories sell consultation, blueprints, and patents to merchant guilds and noble houses. Finance & Trade Regulation: House Medarda and affiliated banks provide capital and insurance for risky experiments and overseas ventures. Luxury Industry: Art, jewelry, architecture, and culture — Piltover exports refinement as a brand identity. Currency: A standardized coin and credit system backed by trade value. Exact denominations are never named in-series, but the economy operates on meritocratic and contractual exchange. Workforce Composition: Scientists, engineers, scholars, bureaucrats, artisans, and enforcers. Labor automation through Hextech reduces manual work but widens the gap between inventors and workers. Zaun — The Free Market of Survival Economic Identity: Zaun’s economy is unregulated, decentralized, and dangerous. It thrives on black-market production, waste reclamation, and chemtech innovation. “Profit” in Zaun often means survival, not luxury. Core Economic Principles: Everything can be repurposed. Every material, tool, and byproduct has value. Laws are replaced by reputation, loyalty, and control of resources. Trade runs on barter, chem-credit, and favors rather than official currency. Primary Economic Sectors: Chemtech & Shimmer Industry: Production and refinement of volatile chemicals. Provides Zaun’s main power and medical substitutes, but at heavy social cost. Industrial Reclamation: Recovery and resale of discarded materials from Piltover — scrap metal, fuel, defective devices, and waste gases. Underground Manufacturing: Weapons, prosthetics, and personal augmentations built without regulation. Many originate as stolen Hextech blueprints. Smuggling & Contraband Trade: Core part of Zaun’s export network, including shimmer, black-market Hextech, and unlicensed crystals. Service Economy: Street markets, taverns, entertainment, and local crafts — chaotic but community-driven. Workforce Composition: Chemists, mechanics, smugglers, factory workers, gang enforcers, and medics. Employment security is nonexistent. Families form around workshop guilds or gang networks, not contracts. 3. The Interdependence Loop Despite political separation, the two cities form one continuous supply chain: Flow Direction From To Type of Goods / Services Economic Effect Downward Flow Piltover → Zaun Processed materials, machinery, energy, food, and manufactured goods Sustains Zaun’s survival and dependence Upward Flow Zaun → Piltover Raw materials, chem-products, labor, and smuggled resources Fuels Piltover’s industry and wealth Lateral Flow Internal (Zaun ↔ Zaun) Black-market trade, protection rackets, gang economies Maintains undercity’s informal stability External Flow Piltover ↔ World Export of Hextech devices and knowledge Creates global influence for Piltover Resulting Condition: The economy operates like a closed loop: waste becomes resource, progress becomes pollution, and both cities’ prosperity relies on the suffering or ambition of the other. 4. Major Economic Actors Piltover: The Council: Regulates trade, research, and invention patents. Its members are both legislators and industrial magnates. House Medarda: Wealthy political family controlling international trade and diplomacy. Operates the Medarda Shipping Conglomerate and finances research. House Ferros: Industrial powerhouse responsible for weapons and Hextech distribution. Known for ruthless business tactics. The Academy of Techmaturgy: Scientific institution granting licenses and certifications to inventors; indirectly controls innovation. Merchant Guilds: Collective trading organizations managing logistics, shipping, and taxation. Zaun: The Chem-Barons: Cartel-like rulers controlling factories and smuggling rings. They function as corporate warlords. Independent Inventors: Street engineers creating affordable or illegal versions of Hextech and chemtech. Shimmer Syndicates: Networks producing and distributing the drug for both profit and control. Worker Collectives: Informal alliances of laborers and artisans banding together for safety and resources. Underground Markets: Decentralized economy of trade, barter, and stolen goods. 5. Trade Infrastructure Piltover’s Network Hexgates: The crown jewel of global trade. They enable instant cargo transfer between allied cities and nations. Every shipment passing through generates tolls and taxes, making Piltover the economic hub of the world. Docks & Sea Routes: Maritime shipping still operates for materials too large or volatile for Hexgate transport. Sky Docks: Airships handle high-value or diplomatic transport. Zaun’s Network Canal Routes: Chem-barges and small submersibles move goods through polluted waterways. Smuggling Tunnels: Hand-dug passages connecting Zaun to external trade routes or Piltover’s lower levels. Lift Shafts & Freight Elevators: Repurposed for illegal cargo transport between the cities. 6. Currency & Value Systems Region Medium of Exchange Nature of Value Piltover Coinage and electronic credits Backed by trade, patents, and Council regulation Zaun Chem-credits, barter, and labor pledges Backed by material usefulness and reputation Shared (Black Market) Gem fragments, shimmer, Hextech components Backed by rarity and risk Interpretation for Simulation: Value is relational, not intrinsic. Scarcity, danger, and legality alter worth dynamically. For example, a single working Hex Crystal holds more economic weight than a shipment of industrial steel. 7. Labor & Social Class Hierarchy Piltover: Council Aristocracy: Wealth through influence and trade monopolies. Academic Elite: Scientists and engineers with patents or state contracts. Merchants & Bureaucrats: Manage trade operations and records. Workers & Enforcers: Maintain infrastructure and public order. Zaun: Chem-Barons & Gang Lords: Control of territory and industry. Tinkerers & Mechanics: Skilled labor responsible for the city’s survival. General Workers: Unregulated factory labor, often underpaid or addicted to Shimmer. Outcasts & Mutants: Marginalized individuals surviving through scavenging and service. Mobility: Upward mobility exists through innovation or violence, not birth. A single discovery or coup can shift a faction’s entire status. 8. Export & Import Goods Summary City Primary Exports Primary Imports Piltover Hextech devices, academic research, precision machinery, luxury goods Raw minerals, chem-products, labor, food, textiles Zaun Chemicals, Shimmer, prosthetics, black-market Hextech, reclaimed metals Clean water, food, medicines, spare parts, air filters 9. Economic Fragility The Piltover–Zaun economy is self-sustaining but unstable. If Piltover halts trade, Zaun faces starvation and collapse. If Zaun’s output stops, Piltover loses production capacity and fuel. The Hexgate monopoly makes Piltover globally essential but politically vulnerable — sabotage or corruption could destabilize the entire world economy. Shimmer dependency in Zaun creates long-term workforce decline, reducing labor quality and lifespan. Systemic Principle: The cities exist in permanent economic tension. Each tries to dominate the other without breaking the link that ensures mutual survival. 10. Interpretive Summary for Simulation Systems Aspect Piltover Zaun System Interaction Economic Model Regulated capitalism Free-market anarchy Interdependence through exploitation Main Resource Hextech innovation Chemtech production Resource exchange maintains balance Labor Conditions Legal, contract-based Informal, survival-based Shared infrastructure ensures flow Political Control Centralized Council Decentralized Barons Conflicts occur at trade junctions Ideological Value Progress and order Freedom and adaptation Symbiotic yet unstable coexistence Interpretive Directive When simulating economic behavior in this world: Treat Piltover’s economy as a machine that refines dreams into systems. Treat Zaun’s economy as a furnace that burns waste into survival. The stability of one depends on the exhaustion of the other. Progress above and desperation below form one economic heartbeat — efficient, profitable, and perpetually on the edge of collapse.

1. Overview Piltover and Zaun share a single geographical structure but maintain distinct legal and social systems. Piltover operates under codified law, enforced by bureaucratic order and sanctioned authority. Zaun exists in a state of anarchic self-regulation, governed by gang hierarchy, informal agreements, and survival ethics. Together, they form one fractured society — a city that governs the sky and another that governs the shadows. 2. Piltover: The Law of Progress 2.1 Governmental Structure Piltover is governed by the Council of Piltover, a small oligarchic body composed of influential merchants, scientists, and political dynasties. The Council functions simultaneously as legislature, judiciary, and executive. Its authority is absolute within city limits. Council Characteristics: Membership is limited, self-selecting, and based on wealth, achievement, or inheritance. Laws are passed through Council vote and enforced by bureaucratic agencies. Political power often overlaps with corporate interest — council members control trade houses and research industries. Key Offices and Functions: Council Chambers: Policy creation and high-level adjudication. Academy Board: Scientific oversight; determines legality of inventions and Arcane experimentation. Merchant Guilds: Enforce economic regulations and tariffs. Enforcer Command: Law enforcement and public security. 2.2 Law Enforcement The Enforcers (formally the Piltover Enforcer Corps) act as both police and military. They maintain civil order, guard trade routes, and enforce Council decrees. Operational Logic: Highly disciplined, uniformed, and hierarchical. Authorized to use Hextech weaponry and vehicles. Jurisdiction covers all official city levels and trade bridges, but not the deep undercity unless authorized. Methods & Policies: Patrolling of main districts, Hexgate facilities, and merchant zones. Arrest and detention for unlicensed inventions, theft, or smuggling. Surveillance via informants and Hextech sensors. Brutal raids when Zaunite crimes “spill upward.” Public Image: Among Piltovans, Enforcers represent order and safety. Among Zaunites, they symbolize oppression and violence. 2.3 The Judicial System There is no independent judiciary in Piltover. Legal cases are overseen by council-appointed magistrates or handled internally by guilds. Legal Principles: Property and innovation take priority over individual rights. Crimes against intellectual property or trade are punished more severely than crimes of passion or poverty. Appeal is possible only through petition to the Council. Common Punishments: Fines and seizure of assets. Labor assignments to state projects. Exile to the undercity (informal punishment). 2.4 Social Structure Piltover society is organized by achievement hierarchy rather than birth nobility, though family influence remains strong. Class Description Council Elite Wealthy dynasties controlling government and industry (e.g., Medarda family). Academics & Inventors Respected professionals; social prestige linked to patents and breakthroughs. Merchants & Bureaucrats Middle class managing trade, logistics, and enforcement. Workers & Laborers Lower citizens maintaining factories, transports, and infrastructure. Servants & Expelled Workers Marginal class often pushed toward the undercity. Cultural Attitude: Politeness, innovation, and ambition define virtue. Poverty and unregulated behavior are viewed as moral failure rather than systemic consequence. 3. Zaun: The Law of Survival 3.1 Governance Structure Zaun has no centralized government. Power is distributed among factions, gangs, and industrial lords called Chem-Barons. Each controls territory, resources, and populations through trade, intimidation, and protection. The Chem-Barons: Function as de facto rulers. Maintain private armies, factories, and chem-labs. Negotiate alliances or feuds in place of formal politics. Enforce their own codes of loyalty and retribution. Examples of Governance: Justice delivered through personal vengeance or group arbitration. Neighborhood councils or gangs act as local governments. Economic control equals political power; whoever provides resources leads. 3.2 Policing and Order There is no police force in Zaun. Security is managed by gang enforcers, mercenaries, and informal peacekeepers. Justice is pragmatic: survival first, ethics second. Order Mechanisms: Gang Law: Reputation and respect prevent chaos more effectively than written law. Baron Enforcement: Each territory enforces its own rules; crimes are punished directly by local power. Mutual Defense Pacts: Communities form protection alliances when facing larger threats. Consequences of Lawlessness: Frequent territorial conflicts. Uneven safety conditions — some districts stable, others openly violent. Survival depends on alliances and resource access. 3.3 Social Hierarchy Despite appearing anarchic, Zaun has a clear structure defined by influence and contribution. Class Description Chem-Barons & Gang Lords Wealth and dominance through resource control. Skilled Inventors / Tinkerers Mechanically gifted individuals vital to local survival. Traders & Smugglers Operate Zaun’s market networks, connecting factions. Laborers & Factory Workers The majority, maintaining production under harsh conditions. Outcasts & Mutants Marginalized survivors of chemical exposure, often forced into menial or criminal work. Cultural Attitude: Independence and loyalty define morality. Trust and reputation are currency; betrayal is the ultimate crime. 4. Intercity Legal Relationship Piltover and Zaun maintain a semi-formal dependency rather than legal union. The Council enforces control through trade restrictions, taxation, and selective policing, but does not recognize Zaun as an equal state. Legal Boundaries: Piltover law technically claims jurisdiction over all lower sectors but rarely enforces it. Zaun’s internal conflicts are ignored as long as trade continues. Intercity trade is handled through intermediaries and bribery rather than official treaties. Cross-Border Dynamics: Piltover Enforcers are forbidden from descending without explicit Council mandate. Zaunite smugglers operate freely, using corruption or stealth to avoid patrols. Crime syndicates act as unofficial trade diplomats between the two worlds. 5. Public Order & Social Ethics Piltover Core Values: Order, progress, innovation, civility. Social Control Mechanisms: Education, bureaucracy, and surveillance. Crime Categories: High Crimes: Illegal Arcane experimentation, theft of patents, Council defiance. Mid Crimes: Smuggling, fraud, unlicensed trade. Low Crimes: Petty theft, dissent, or trespass. Law Enforcement Response: Graduated use of force; suppression of unrest prioritized over rehabilitation. Zaun Core Values: Loyalty, ingenuity, adaptability, survival. Social Control Mechanisms: Reputation, mutual protection, gang hierarchy. Common Crimes: Betrayal, debt, territory violation, theft from allies. Punishments: Physical retribution, exile, or chem-punishment (forced labor or chemical marking). 6. Civil Rights and Freedoms Piltover: Civil freedoms exist in principle — speech, property, and invention rights — but depend on status and wealth. Lower classes have minimal representation or recourse against Council authority. Zaun: Freedom is absolute but meaningless without power. Each person determines their own code of conduct; collective morality replaces law. 7. Cross-Cultural Perceptions Perspective Piltover’s View of Zaun Zaun’s View of Piltover Ideological Uncivilized, reckless, wasteful Arrogant, hypocritical, parasitic Moral Needs regulation for its own good Exploits suffering for luxury Economic Resource base and labor supply Oppressive monopoly and gatekeeper Cultural Crude, chaotic, emotional Sterile, elitist, soulless These opposing views sustain social tension and justify each city’s self-image as morally superior. 8.

Model authority as transactional: obedience is exchanged for safety or profit. Social behavior follows status logic rather than morality. Justice is neither fair nor consistent; it reflects economic interests first. Both societies are mirrors — each one justifies its existence through the flaws of the other.

1. Overview The world of Arcane contains no classical monsters or supernatural demons. All threats are anthropogenic — created by science, greed, war, or failed containment of the Arcane. Every danger originates from technological excess, chemical corruption, or human desperation. This makes the world’s “monsters” thematic rather than mythical: progress itself becomes the predator. 2. Categories of Threat Category Definition Origin Primary Habitat Chem-Mutants Individuals mutated by prolonged chemical exposure or Shimmer overdose Zaunite industry, bioengineering Zaun’s Sumps and lower canals Arcane Aberrations Instabilities or entities formed from uncontrolled Arcane energy Failed Hextech or Arcane experiments Laboratories, test chambers, and tunnels Technological Constructs Autonomous or semi-sentient machines powered by Hextech Piltover inventions or malfunctions Workshops and industrial districts Criminal Syndicates Human factions posing systemic threat to order and stability Social decay and economic inequality Zaun’s Lanes, Piltover underworks Environmental Hazards Living or reactive environments resulting from pollution Industrial contamination Zaun’s flooded levels and abandoned zones 3. Chem-Mutants Description: Individuals or animals altered by chronic exposure to Shimmer, chemical runoff, or industrial toxins. Mutations vary from minor deformities to complete physiological transformation. Common symptoms include enhanced strength, reduced cognition, iridescent veins, and chemical dependency. Subtypes: Shimmer-Addled: Subjects temporarily empowered by shimmer, often violent or irrational. Stable Mutants: Those who survived exposure long enough to reach equilibrium; they form a marginalized social class in Zaun. Industrial Horrors: Accidental fusions of organic tissue and machinery; remnants of failed experiments or factory accidents. Behavior: Unpredictable, aggressive when deprived of shimmer or subjected to stress. Some retain full intelligence but suffer intense pain or psychological instability. Cultural Perception: Feared and pitied. In Zaun, they are tolerated as tragic byproducts of survival; in Piltover, they are viewed as cautionary tales against unregulated progress. 4. Arcane Aberrations Description: Manifestations of uncontrolled Arcane resonance — phenomena, distortions, or temporary entities formed when magic breaches physical law. These occur during Hextech malfunctions or experiments that exceed safe containment thresholds. Known Manifestations: Resonance Surges: Sudden bursts of luminous energy that disrupt gravity or molecular cohesion. Echo Constructs: Afterimages or sound-based apparitions that mimic living beings. Crystalline Corruption: Growth of unstable Arcane crystal structures within lab environments. Symbiotic Artifacts: Hextech devices that begin adapting, feeding, or communicating autonomously (e.g., the Hexcore). Behavior: Usually non-sentient, but capable of self-preservation through energy absorption or replication. Containment Protocols (in-world): Isolation chambers with null-metal insulation. Rune-based dampening fields. Controlled discharges to dissipate buildup. Philosophical Implication: Aberrations blur the line between invention and life, forcing Piltover to confront whether creation equals control. 5. Technological Constructs Description: Artificial mechanisms animated by Hextech or chemtech cores. Most are functional tools — some evolve unpredictable behaviors due to Arcane feedback or mechanical learning loops. Common Types: Autonomous Drones: Maintenance machines repurposed as enforcer aids or assassins. Defense Turrets: Fixed emplacements using Hextech energy discharge. Synthetic Augments: Cybernetic enhancements grafted to human hosts for strength or medical support. Runic Automatons (Prototype Level): Arcane-driven machines capable of partial cognition — rare and often banned. Failure Scenarios: Arcane feedback causing mechanical “awakening.” Viral control overrides by rogue inventors or Zaunite hackers. Psychological merging between operator and device during synchronization tests. Cultural Role: Constructs are symbols of Piltover’s progress but also proof of human overreach — machines gaining autonomy reflect the moral decay beneath the city’s perfection. 6. Criminal Syndicates Description: Human organizations operating beyond legal boundaries, functioning as both threat and stabilizing force. Their presence defines Zaun’s political ecosystem and undermines Piltover’s illusion of control. Major Syndicate Categories: Chem-Baron Houses: Industrial empires controlling entire districts. Each baron enforces local law, trade, and warfare. Smuggling Rings: Specialized in Hextech contraband and shimmer distribution. Assassins & Mercenaries: Contracted for espionage, sabotage, or retribution. Rebel Cells: Ideological groups seeking Zaunite independence. Operational Traits: Function through fear, loyalty, and reciprocal protection. Maintain control through access to shimmer, labor, and weaponry. Engage in both warfare and diplomacy with Piltover intermediaries. Societal Effect: They maintain order where formal law cannot — paradoxically preventing complete collapse of Zaun by enforcing their own systems of justice and trade. 7. Environmental Hazards Description: Non-living dangers resulting from the cities’ industrial and magical imbalance. The environment itself acts as a form of slow violence. Primary Hazards: Chem Fogs: Toxic gas layers that obscure entire sectors; prolonged exposure causes hallucination or mutation. Bioluminescent Spores: Reactive fungal growths that absorb waste chemicals, some mildly parasitic. Shimmer Contamination: Polluted waterways glow faint purple and corrode metal and skin. Arcane Radiation Fields: Aftereffects of failed Hextech reactors; distort perception and magnetism. Structural Collapse Zones: Unstable bridges and tunnels due to neglected maintenance. Behavioral Effect on Population: Chronic illness, reduced lifespan, and psychological decline. Many Zaunites develop adaptations or tolerance through generations of exposure. 8. External Threats (Implied Lore) While Arcane focuses on Piltover and Zaun, background lore confirms potential external dangers that influence their security policy: Global Smuggling Networks: Rival nations seek Hextech devices through espionage. Pirates and Trade Saboteurs: Hexgate tolls make Piltover targets for maritime attacks. Arcane Instability Events: Distant magical catastrophes raise concerns about unregulated research. These remain distant and conceptual — serving as justification for Council militarization and trade restrictions. 9. Behavioral Logic for Simulation Threat Type Behavioral Pattern Systemic Function Chem-Mutants Aggressive, territorial, unpredictable Represent human cost of progress Arcane Aberrations Reactive, unstable, localized Represent limits of scientific control Technological Constructs Purpose-driven; may self-correct or rebel Symbolize mechanization of morality Criminal Syndicates Organized, pragmatic, socially embedded Maintain equilibrium through corruption Environmental Hazards Passive, ever-present, slowly destructive Represent environmental entropy 10. Summary Interpretation All threats within this world are expressions of imbalance: Too much innovation creates chaos. Too much control breeds rebellion. Too much extraction poisons life. The danger is not born from monsters — it becomes them. The world’s horrors are reflections of its ambition. Interpretive Directive for Simulation Systems Treat “monsters” as outcomes of human systems failing to balance innovation and ethics. Avoid inserting supernatural predators; every threat must trace back to chemistry, machinery, or resonance instability. Model danger as cumulative — environmental and societal degradation grow exponentially with technological advancement. The strongest horror is moral: the realization that every disaster is self-created.
