Solo Leveling (Remix)

The world in is modern-day Earth, technologically equivalent to the early 21st century. Cars, firearms, drones, satellites, the internet, global governments, corporations, and media all exist exactly as you’d expect. On the surface, it looks like our world. The difference is that about ten years ago, magic forcibly entered reality—and it never left. This is a high-magic world imposed onto a modern, low-fantasy setting. Magic does not replace technology; it sits on top of it and frequently breaks it. One day, massive portals called Gates began appearing across the globe. These Gates connect Earth to hostile dimensions filled with monsters, strange ecosystems, and powerful magical beings. If left uncleared, a Gate will rupture, unleashing its monsters directly into the real world and devastating entire cities. Because of this, dungeon-clearing is not adventuring for glory—it is disaster prevention. When the Gates appeared, some humans awakened to magic and became known as Hunters. Hunters gain supernatural abilities: enhanced bodies, spellcasting, summoning, or specialized combat powers. However, this world has a crucial limitation that sets it apart from most fantasy settings: power is fixed at birth. Once a person awakens, their strength is locked forever. Training improves skill, not raw power. Hunters are ranked from E to S, and these ranks define social class, political value, income, and even legal protection. S-rank Hunters are treated as strategic weapons. E-rank Hunters are disposable labor. Dungeons exist inside Gates and function like enclosed fantasy realms. Each dungeon has its own terrain, monsters, rules, and a boss that anchors the Gate. Killing the boss collapses the dungeon and closes the portal. Monsters drop mana crystals and magical materials that fuel an entire global economy, creating guilds that operate like megacorporations and private armies. Governments regulate Hunters, but in practice, power often outweighs law. Behind all of this is the truth no ordinary person knows: Earth is not unlucky—it is a prepared battlefield. The Gates are not accidents. They are part of a long, ancient interdimensional war between godlike beings known as the Rulers and the Monarchs. The Monarchs are incarnations of destruction, each commanding legions of monsters and seeking to erase or conquer worlds. The Rulers oppose them, but they are not benevolent gods. They see worlds as assets and wars as calculations. Earth is being slowly saturated with magic so it doesn’t shatter when the real invasion begins. The single most unique element of this world—and the axis your campaign can revolve around—is the existence of a hidden System. This System applies game-like rules to reality, but only to chosen individuals. It grants levels, stats, quests, skills, inventories, and even death-defying mechanics. In a world where no one can normally grow stronger, the System creates beings who can scale infinitely. These individuals are not heroes by default; they are weapons in a cosmic war, whether they know it or not.

Geographically, this world is still Earth as we know it: the same continents, oceans, climates, and borders. However, magic has rewritten how geography functions. The planet is no longer static. Certain locations become strategic, cursed, or sacred not because of terrain alone, but because Gates choose them. The World at Large All nations exist as modern states rather than medieval kingdoms, but in practice many function like magical city-states backed by military force and elite champions. Borders matter less than Hunter power. A country with several S-rank Hunters is a superpower regardless of size. A country without them lives in fear of collapse. The world can be roughly divided into three layers of geography: Normal physical geography (cities, mountains, seas) Gate-prone regions (high mana instability) Temporary dungeon realms that overwrite reality until cleared Major Nations and Power Centers Korea (Korean Peninsula) A major focal point of the world due to unusually frequent Gates and several high-profile Hunters. Seoul is a dense, modern megacity that regularly experiences Gate emergencies, evacuations, and Hunter activity. The Korean Hunter Association is highly organized, and guild rivalries shape much of the internal power balance. A key geographic scar is Jeju Island, once overrun by an S-rank dungeon breakout. It became a monster-infested dead zone for years, effectively a lost territory, until a massive international raid reclaimed it. Jeju stands as a reminder that land itself can be “lost” to magic. Japan An island nation heavily dependent on Hunters for survival. Dense cities like Tokyo are under constant threat from urban Gates, making evacuation routes, underground shelters, and rapid-response strike teams essential. Japan’s Hunter culture emphasizes elite strike forces and strict control, but the nation is fragile—when high-level Hunters fall, entire regions become vulnerable. United States One of the strongest global powers due to vast resources and multiple S-rank Hunters. Major cities such as Los Angeles, New York, and Washington D.C. are protected by layered Hunter defenses. The U.S. operates like a magical superpower, often intervening internationally through Hunter deployment. Certain regions, especially deserts and mountain ranges, are used as controlled Gate-clearing zones to minimize civilian casualties. China A massive land power with a large number of high-ranking Hunters. Its sheer population produces many awakenings, making it one of the most dangerous nations to challenge directly. Entire provinces can be locked down during dungeon emergencies. Remote regions are sometimes quietly sacrificed or isolated when containment fails. Europe Fragmented but influential. Nations like Germany, France, and the UK maintain strong Hunter associations, but coordination across borders is inconsistent. Ancient cities often sit atop unstable mana zones, creating dangerous overlaps between historical landmarks and dungeon activity. Eastern Europe contains several regions unofficially abandoned due to repeated breakouts. Other Regions Africa, South America, and parts of the Middle East experience Gates as well, but often lack sufficient Hunter infrastructure. Some areas become recurring disaster zones, while others are exploited by foreign guilds seeking resources. Entire cities have vanished from maps, classified as “unrecoverable.” Cities Major cities are no longer just population centers—they are battlefields. Cities with strong Hunters thrive and attract wealth. Cities without protection shrink or are evacuated entirely. Many urban areas have reinforced districts, evacuation corridors, and “Hunter-only” zones. Some cities are effectively ruled by guilds rather than governments, with Hunters acting as both protectors and enforcers. Geographic Features Shaped by Magic Gate Hotspots Certain regions experience frequent Gate formation due to mana instability. These areas are heavily monitored or permanently restricted. Over time, mana saturation can alter weather patterns, wildlife, and even human behavior nearby. Dungeon Zones When a Gate opens, it temporarily overwrites geography. A city block might become a forest, a subway tunnel might turn into a catacomb, or a mountain might house a frozen citadel. These spaces exist outside normal physics until cleared. Dead Lands Areas that suffered massive dungeon breakouts. These regions may be poisoned with residual mana, crawling with monsters, or simply too dangerous to reclaim. Jeju Island is the most famous example, but many smaller dead zones exist worldwide. The Hidden Geography Beyond Earth lies the true map most people never see: overlapping dimensions ruled by Monarchs and Rulers. These realms do not appear on any human map, but their influence shapes where Gates open and where disasters strike.

Humans are the dominant and only openly recognized race on Earth, but they are no longer a single, equal people. Humanity is culturally and politically fragmented much like our real world, but the emergence of magic has created a new internal divide more important than nationality: the awakened and the unawakened. Unawakened Humans The majority of the population. They live normal lives but exist under constant threat. Entire cultures have developed around evacuation drills, disaster broadcasts, and Hunter worship. In practice, they are a protected class with little agency in times of crisis. Hunters (Awakened Humans) A minority race in all but name. Hunters are physically and magically superior and form a de facto ruling caste in many regions. Their culture varies by nation, but common traits include: Strong hierarchy based on rank High fatalism among low ranks Celebrity worship of high ranks Moral desensitization due to constant combat Relationships between Hunters and civilians are tense. Hunters are admired, feared, resented, and relied upon—often all at once. Territorially, humans still occupy all nations, but effective control often lies with guilds rather than governments. In some cities, guild headquarters are more important landmarks than city halls.

Gates are appearing more frequently and stronger, straining Hunters and governments. Guilds dominate power, hoard resources, and sabotage rivals, while nations without elite Hunters struggle, sometimes detaining or poaching foreign Hunters. Dead zones show signs of organization, hinting at Monarch influence, and dungeon bosses are growing intelligent and strategic. The Rulers have withdrawn, leaving humanity exposed, while System anomalies—individuals who break the rules of power—are emerging, becoming targets for control or elimination. In short, the world is unstable, power is concentrated, alliances are fragile, and every crisis—political, supernatural, or personal—is an opportunity for danger and adventure.

How Magic Works Magic in this world is real, abundant, and invasive, but not natural to Earth. Magic originates from mana, a form of extradimensional energy that leaked into the world when the Gates first appeared. Mana does not behave like a learned art or ambient force; it reshapes biology and physics around it. Areas saturated with mana become unstable, allowing reality to be overwritten by dungeon environments. Magic does not respond to study or belief. It responds to compatibility. Only individuals whose bodies and souls can endure mana exposure awaken to magical abilities. This awakening is involuntary and unpredictable. Once awakened, mana permanently alters the individual’s body, granting supernatural strength, resilience, or spellcasting abilities. A defining rule of the world is that magical growth is normally impossible. An awakened individual’s mana capacity and potential are fixed at the moment of awakening. Training improves control and technique, not raw power. This creates a rigid magical hierarchy enforced by biology itself. Who Can Use Magic Hunters are the only humans capable of actively wielding magic. They instinctively understand how to use their abilities, though mastery still requires experience. Civilians cannot cast spells, channel mana, or use magical artifacts without a Hunter’s assistance. Dungeon creatures naturally wield mana as part of their existence. Their biology is built around it. There is one exception: individuals bound to the System, who operate under entirely different rules. The System artificially expands mana capacity, converts effort into growth, and imposes structured progression where none should exist. Forms of Magic Magic manifests in structured but limited ways: Physical enhancement (strength, speed, durability) Elemental abilities (fire, ice, lightning, poison) Summoning and necromancy Stealth, perception, and spatial distortion Passive resistances and aura-based effects Spellcasting is not academic. There are no spellbooks or schools of magic. Abilities are intrinsic, often reflecting the individual’s temperament or affinity. Religion and Belief Traditional human religions still exist, but they are no longer unified or stable. Some people interpret the Gates as divine punishment, others as trials, and others as proof the gods are dead or indifferent. New cult movements have emerged worshiping Hunters, dungeon bosses, or the idea of transcendence through awakening. Prayer does not grant magic. Faith does not alter mana. The Rulers and the Monarchs Above all belief systems exist beings that function as deities in practice, though not in morality. The Rulers are ancient, godlike entities aligned with order and preservation. They do not require worship and do not answer prayers. When they intervene, it is through chosen agents, visions, or indirect empowerment. The Monarchs are incarnations of destruction and domination. They command races and dimensions and actively seek conquest. Some are worshiped by dungeon civilizations as gods, though this devotion is enforced through fear. Neither faction draws power from belief. They are self-sustaining cosmic forces.

Earth is a contested battlefield, not a neutral world. Other planes press into it through Gates, which temporarily overwrite reality with foreign terrain, physics, and ecosystems. Monsters, bosses, and dungeons are fragments of these planes; killing them severs the connection but does not destroy the original world. Monarchs control distinct planes—frozen wastelands, shadow realms, infernal landscapes—and influence Earth by seeding Gates, empowering dungeon rulers, and corrupting regions. Rulers exist in a higher abstract plane and intervene subtly through agents, artifacts, or mechanisms like the System. Between planes lies a metaphysical Sea of the Afterlife, where souls and residual power drift. Certain Monarchs manipulate this sea to create undead or shadow armies. Repeated Gate activity leaves mana-scarred lands and “thin spots” that increase future incursions. Earth survives only because the Monarchs and Rulers maintain balance—long enough for the planet to serve as a battlefield or produce key players. In short, other planes do not merge politely; they invade in fragments, leaving cracks that adventurers must defend, explore, or exploit.

Pre-Awakening Era (Before Gates) The world resembled modern Earth, with familiar nations, cities, and technology. Magic was unknown or only whispered about in myth. Human civilizations were shaped entirely by politics, economics, and technology. Many ancient ruins that survive from this period are mundane—castles, temples, and fortifications—but some were unknowingly built on latent mana nodes, later becoming Gate hotspots. The First Incursion (Gates Appear) Roughly ten years ago, the Gates appeared suddenly, introducing monsters, dungeons, and mana into the world. Humanity was unprepared; cities were devastated, governments scrambled, and nations scrambled to organize Hunters. This era established the Hunter hierarchy, the first guilds, and the global recognition that Earth is not merely a planet, but a battlefield. The Awakening Era (Hunter Society Emerges) As more humans awakened, Hunters became the central political and social force. Guilds consolidated power, governments ceded authority over disaster response, and urban planning shifted to accommodate dungeon emergencies. Dead zones were mapped, partially reclaimed, or abandoned entirely. Ancient ruins were often overwritten by dungeons, leaving fragmented landscapes where pre-Gate civilization and dungeon architecture intersect. Early Monarch Influence High-ranking dungeons revealed signs of intelligent strategy, indicating that Monarchs were already manipulating Earth. Certain Gates carried new species, artifacts, and anomalies, hinting at a larger cosmic war. This era left behind artifacts, corrupted zones, and dormant dungeons—legacies of Monarch planning—that persist today as high-risk zones or powerful resources. Current Era (Global Tension) The world today exists in a fragile balance: Gates are increasing in frequency, dead zones are stirring, and political and guild rivalries are intensifying. The legacies of past eras remain everywhere: Ruined cities and dead zones where prior disasters were too great to reclaim Ancient artifacts scattered in dungeons or hoarded by guilds Residual mana zones that warp reality and attract new Gates Hunter culture and social hierarchy cemented into every nation

Currency and Wealth Traditional money (dollars, won, yen, euros) exists, but mana-based resources—mana crystals, dungeon materials, monster organs, and artifacts—are often more valuable. S-rank Hunters and guild leaders control wealth far beyond conventional currency. Trade Networks Trade operates on two layers: Civilian trade: Food, tech, and raw materials follow normal routes but require security in dungeon-prone areas. Magical trade: Guilds dominate the flow of mana, artifacts, and dungeon materials. Black markets thrive in dangerous or abandoned zones. Guilds and Power Guilds act as megacorporations, controlling dungeon access, resources, and Hunter labor. They influence markets, negotiate treaties, and sometimes bypass governments entirely. Black Markets and Scarcity Illegal trade of artifacts, monster cores, and awakened humans is common. Dangerous dungeons make resources rare, inflating their value. Hunter wages are astronomical, and cities constantly rebuild after breakouts.

Justice and Governance Traditional governments still exist, but real power lies with Hunters and guilds. Laws are enforced inconsistently: high-rank Hunters can act with near impunity, while civilians are heavily restricted during dungeon incidents. Governments rely on guilds for security, evacuation, and containment, often outsourcing justice to those with the strength to enforce it. Courts exist but have limited authority over powerful Hunters. Guilds often run their own internal justice systems—punishments, trials, or executions—especially for breaches of dungeon protocols, theft of artifacts, or betrayal. Black markets and rogue Hunters operate in the gaps, making law enforcement reactive rather than proactive. Social Perception of Adventurers Adventurers (Hunters) are a caste apart: They are respected for their power and role in protecting civilians. They are feared because of their destructive potential and political influence. They are idolized or resented, depending on rank and notoriety. High-ranking Hunters are treated like celebrities or even quasi-nobility, while lower ranks are considered expendable labor by both guilds and governments. Civilians often rely on Hunters for survival but have little real power over them. Cultural Impact Society is hierarchical and survival-focused. Laws are pragmatic, designed to minimize dungeon casualties rather than ensure fairness. Adventurers are both the shield and the threat, and their actions can shape cities, economies, and politics.
