World Overview
THE CORE PREMISE OF SANDS OF THE SUNLESS REACH
"The world has stopped spinning. One half burns beneath a sun that never sets. The other lies frozen beneath an eternal night. Between them, in the twilight strip called the Shatterbelt, the last civilizations wage war, scrape by, or go mad."
🔮 MAGIC LEVEL: Mid to Low Magic (but Weird as Hell)
Magic exists, but it is scarce, dangerous, and often misunderstood.
Few true arcanists remain; those who wield magic often do so through machine remnants, forbidden lore, or Carcosan corruption.
Divine magic is filtered through twisted ideologies — sun cults, frost mystics, dream worshippers.
Magic often alters the world unnaturally — time loops, hallucinations, gravity shifts.
Spells can mutate, especially near Carcosa or the Gyrosoul.
Magic is a resource — sometimes revered, sometimes feared. It is not convenient. It’s mythic, volatile, and alive.
⚙️ TECHNOLOGY LEVEL: Post-Arcane Apocalyptic Diesel-Fantasy
Imagine if Eberron had a baby with Mad Max and then that child read The King in Yellow by candlelight during a sandstorm.
Key Features:
Arcano-mechanical technology litters the landscape — broken world-engines, derelict airships, radio towers that whisper madness.
Functioning tech is cobbled together from relics of ancient, godlike civilizations.
Vehicles are sacred, cobbled beasts powered by solar coils, blood-fuel, or psychic batteries.
Firearms exist but are rare and unreliable (think black-powder revolvers, rune-scorched rifles).
No internet, no industry, no printing presses — communication is by radio signal or wandering lorekeeper.
The world is a scrapyard of forgotten miracles and half-recalled nightmares. Progress is about rebuilding what the gods abandoned.
🧭 UNIQUE WORLD ELEMENTS
Here’s what truly sets Sands of the Sunless Reach apart from other D&D settings:
🔥 Tidal Lock World
The planet does not rotate.
One half is scorched by an eternal sun (The Burning Wastes).
The other is frozen in pitch-black night (The Sunless Reach).
The only “livable” zone is the Shatterbelt — the volatile dusk band in between.
Travel between regions is life-threatening — heatstroke, frostbite, and planar instability await.
🎭 Carcosa's Influence
A cosmic-eldritch presence haunts the world.
Whispers of a Mirror Sun — visible only in reflections and dreams.
The King in Yellow is not just a figure — he is a force, a script, a fate.
Dreams bleed into reality. Some NPCs repeat lines from future events. Masks have power.
Carcosa represents the fractal edge of madness, the final truth behind reality.
Reality itself is untrustworthy. Even the sun may be a lie.
⚙️ The Gyrosoul
An ancient, mythic planetary engine — long buried and half-forgotten.
Said to have once rotated the world.
Can be restarted… or fed to the Mirror Sun.
At the heart of the campaign’s core moral dilemma: Balance or Rewrite?
🚗 Sacred War Machines
Vehicles are not just tools — they are temples, weapons, homes, and avatars.
Each faction has their own war machines — powered by tech, magic, blood, dreams.
Players can build, upgrade, or even bind with their vehicles.
Entire battles and heists revolve around vehicular strategy.
🧠 Dreams, Sanity, and Time Loops
Dreams are often shared, prophetic, or manipulated by Carcosa.
Sanity is a real mechanic — or at least a narrative tool.
Time is not stable. The closer players get to Carcosa or the Gyrosoul, the more nonlinear events become.
Players might encounter versions of themselves from alternate timelines… or past lives.
🎭 TONE: A Theater of Sand, Madness, and Broken Gods
Imagine Mad Max: Fury Road as directed by David Lynch, written by Neil Gaiman, with a script edited by Robert W. Chambers.
Characters live on the edge of desperation, often forced to choose between survival and sanity.
The game swings between:
High-octane action (vehicle chases, wasteland raids)
Introspective horror (dream sequences, philosophical madness)
Political intrigue (faction choices, betrayals, regional power dynamics)
Surreal mythic revelations (visions of suns that don’t exist, cities that remember)
🎮 PLAYER EXPERIENCE
Players begin as scavengers, survivors, or mercenaries, gradually rising to world-changers, mythic figures, or masked dream-avatars.
Every choice matters — factions react, the world shifts, the ending is determined entirely by player actions.
You can lean heavily into:
Cinematic vehicle combat
Moral decision-making
Mystery unraveling
Exploration of surreal, hostile biomes
Geography & Nations
The World of Diros
A planet frozen in tidal lock, scorched on one side, frozen on the other, and torn by war in between.
🌗 THE SHATTERBELT
The Twilight Zone Between Flame and Frost
The livable strip between the Burning Wastes and the Sunless Reach. A mix of shattered civilizations, scavenger outposts, warring caravans, and miracle-hunting factions.
🛞 Sanctum Veloce — The Rolling City
A colossal nomadic fortress-city that crawls across the Shatterbelt on tank treads.
Divided into strata (the Spires, the Crankbelt, the Forgegut, etc.)
Ruled by Governor Thorne, who maintains control through scarce fuel, iron laws, and strategic trade.
Home base in Act I. A neutral ground (for now).
“It does not rest. It only slows to kill.”
⚖️ The Ten Thousand Path Camp — Pilgrimage Enclave of the Duskbound Caravan
A roving, tent-based settlement of mystics, monks, and lorekeepers who follow the principle of balance.
Moves seasonally — always avoids conflict zones.
Known for oracles, desert monks, and a sacred library cart said to contain a copy of every book ever burned.
📻 The Echo Spires — Dead Signal Towers That Broadcast the Future
Cluster of ancient towers along a broken mountain ridge.
The Echoed Voice broadcasts cryptic prophecies from here — often referencing events yet to happen.
Explorers who reach the summit often disappear… or return changed.
🪨 The Black Spiral — Gyrosoul Surface Ruin
A crater-pocked ruin at the center of the Shatterbelt.
A known place of temporal instability, guarded by automated constructs and gravitational anomalies.
Contains surface access to the Gyrosoul, though deeper control cores are buried beneath.
🔥 THE BURNING WASTES
The Sunward Hemisphere
A land of scorched glass dunes, firestorms, bone-blasted deserts, and tyrannical war-kings. The sun never sets, and even stone melts if left exposed too long.
🔥 Scorchspire — Seat of the Solar Clergy
A colossal obsidian tower that focuses sunlight into divine energy.
Home to the Solar Tyrant Kel’Zun and his fire-priests.
Filled with archives of altered scripture and weaponized theology.
Holds one of the Gyrosoul Keys: the Solar Core.
“The sun does not set. That is heresy.”
🛠️ The Crucible Fields — Manufactories of the Chrome Ascendancy
Endless foundries and machine-farms powered by solar furnaces.
Population lives in heat-resistant bunkers or within mobile siege-creches.
Headquarters of the Chrome Ascendancy: techno-zealots who believe machines are avatars of the Undying Sun.
🏜️ The Rattlemaze — Living Dunes of Shifting Scrap
A region where massive rusted automatons crawl beneath the surface.
Metal dunes shift constantly, swallowing anything that dares cross them.
Home to the Sandborn Tribes, nomadic raiders who claim to speak to the buried machines.
🪞 The Temple of the Glare — Sun-Driven Mind Control Cult
A place where sunlight is concentrated into psionic induction rays.
Converts the minds of prisoners into loyal flame-chanters.
Rumors say the temple has a mirror that shows a second sun — and that only one priest dares look at it.
❄️ THE SUNLESS REACH
The Frozen Hemisphere
A place of perpetual night, freezing windstorms, psychic snow, and ancient ruins swallowed by silence. The stars here are wrong — some shimmer with yellow flame, and others seem to weep.
❄️ Lake Hali — Frozen Mirror of the Dreaming Sun
A massive lake of glacier-glass, partially buried in frost.
Shows reflections not of the present, but of other realities.
A Gyrosoul Key, the Frost Heart, is buried in its depths.
Glimpses of Carcosa are visible through the ice.
“Do not look too long. The lake looks back.”
🧊 The Cracked Dome — Abandoned Star Observatory
A shattered facility once used to track stars — before the stars began changing.
Filled with arcane telescopes, dream-writing machines, and hollowed-out scientists.
One telescope points directly at a constellation that shouldn’t exist.
🎭 The Forgotten Stage — Carcosan Ruin in the Ice
A stone amphitheater uncovered from beneath the glacier.
Covered in golden masks and indecipherable play scripts.
At night, masked actors appear and reenact scenes — some with the players in them.
🕯️ Penance Spiral — Frostwrought Undead City
Built in concentric rings around a dead god’s skeleton, now frozen upright.
Inhabited by the Frostwrought, undead beings guided by dreams of a world reborn.
Peaceful, but profoundly disturbing. They speak in prophecy.
🎭 POCKET REALITY: CARCOSA (Layered Onto the Real World)
Carcosa is not a place in the traditional sense — it is layered beneath and within reality.
Appears through mirrors, dreams, reflections on snow and glass, and psychic bleed.
Key locations overlap with real-world places, becoming accessible via dream, madness, or mechanical breach.
Notable locales within Carcosa:
Carcosan Location Description
The Yellow Court The throne chamber of the King in Yellow — filled with masked courtiers frozen in place.
The Spiral Library A library that contains every version of every possible decision the players might make.
The Mirror-Sun Skyfields A desert of stars and twin suns. Walk long enough, and you might find your reflection... waiting.
🪐 PLANETARY CORE: THE GYROSOUL
Located deep beneath the Black Spiral.
A partly sentient machine of rotating rings, celestial engines, and living metal.
Access requires all three Gyrosoul Keys.
Inside, time fractures and the players may meet alternate versions of themselves.
The final decision of the campaign happens here.
“You may turn the world again… or let it stay broken. Or feed it to the sun behind the sun.”
🗺️ REGIONAL TRAVEL CONSIDERATIONS
Region Hazard Type Travel Advice
Burning Wastes Fire, dehydration, sunstroke, solar beams Travel underground or at dusk; bring coolant
Sunless Reach Frostbite, madness, psychic storms Use light magic, avoid mirrors, limit exposure
Shatterbelt Faction warfare, sandstorms, political risk Fast travel via rigs or caravans; maintain neutrality unless aligned
🧭 MAP OPTIONS & WORLD SIZE
While Diros is not Earth-sized (you may scale it as needed), the three regions are vast. Use a hex-grid map if you want sandbox travel.
Alternatively, build modular region maps:
One for the Shatterbelt (Act I)
One for each extreme zone (Act II)
One abstract dream map for Carcosa travel (Act III)

Races & Cultures
SUNBOUND RACES — The Fire-Scarred
These peoples have evolved or adapted in the Burning Wastes, enduring the unrelenting sun.
Ashborn Humans
"We are not descended. We are forged."
Sun-scarred, calloused skin, often covered in ash tattoos.
Culturally tied to the Chrome Ascendancy and the Solar Clergy.
Fire-resistant rituals grant them advantage on Constitution saves vs. heat.
Strong caste systems: scav-worker, flame-scribe, fire-knight.
Worship the Undying Sun as a god of purity and flame.
Territory: Scorchspire, Crucible Fields, Rattlemaze
Relations: Distrustful of frostbound cultures; see Carcosa as a heresy or corruption.
Cinderspawn Tieflings
"The blood of fire runs thin, but it runs true."
Lineage twisted by generations of exposure to solar overcharge.
Horns often cracked and glowing, skin like scorched ember.
Naturally resistant to fire; many possess unstable flame-like sorcery.
Held as divine mutants by the Solar Clergy.
Territory: In and around Scorchspire; often held in high regard or feared.
Relations: Respected and feared by Ashborn. Hunted by Black Veil inquisitors.
Scrapkin Goblins
"Steel is our skin. Oil is our blood."
Goblins that have adapted into scrapwrights, expert scavengers and engineers.
Commonly pilot and maintain war rigs.
Worship ancient engines as gods; often semi-feral, but brilliant with tech.
Run pit crews, salvage guilds, and explosive worship cults.
Territory: Crucible Fields, deep in the Wastes, inside crawling junk-fortresses.
Relations: Trade with Chrome Ascendancy; hated by Carcosan cults who view tech as impure.
❄️ FROSTBOUND RACES — The Ice-Touched
Shaped by the Sunless Reach, these people live in darkness and know how to read dreams, survive blizzards, and resist Carcosa's calls — or succumb to them.
Glacierborn Elves
"We hear the stars scream. We write what we can remember."
Pale-blue skin, often hairless, with glowing eyes.
Long-lived, but most suffer echo-dream syndrome — remembering other timelines.
Serve as scholars, navigators, and loreweavers.
Closely tied to the Black Veil, sometimes bred for memory precision.
Territory: Ice monasteries, deep Reach ruins, frozen observatories.
Relations: Feared by sunbound races; respected by the Duskbound Caravan.
Veilmarked Drow
"We are not what we once were. That is a comfort."
Drow who fled the Underdark centuries ago and adapted to the surface cold.
Now psychically sensitive to Carcosa's whispers.
Many wear yellow-veined masks to protect themselves from dream-breach.
Steeped in prophecy, often serving as navigators through the unreality zones.
Territory: The Frozen Spiral, Lake Hali outskirts, the Cracked Dome.
Relations: Seen as cursed. Shunned even by other frostbound. Valuable, but dangerous.
Frostwrought (Undead)
"We died. We woke. We walked toward the sun behind the sun."
Semi-sapient undead whose minds are shared across distances.
Not evil; some seek peace, others spread Carcosa.
Immune to cold. Some retain memories of past lives — often from other timelines.
May serve as prophets, guards, or secret agents of the Yellow Court.
Territory: Penance Spiral, mirrored halls under the snow.
Relations: Abhorred by the Solar Clergy. Tolerated by the Black Veil.
🌗 TWILIGHT RACES — The Shatterborn
Those who live in the Shatterbelt are neither wholly flame nor frost — they are balance-born, but often broken.
Ironblood Dwarves
"The world broke. We did not."
Live inside rolling engine-clans — mobile fortress-factories.
Skin often stained with oil and soot. Eyes modified with arcane lenses.
Master engineers, but more religious than scientific. Believe in the divine soul of machines.
Developed mech-scripture: a theological language made from gear-turns.
Territory: Mobile forge-clans in the Shatterbelt, some allied to Sanctum Veloce.
Relations: Neutral — respected by all, feared when provoked.
Sandwalker Halflings
"We go where others fear to fall."
Desert nomads who travel the sand alone or in tight family packs.
Experts at water-finding, storm-dodging, and dream-mapping.
Believe the Mirror Sun is part of the cycle, not a threat.
Some are Mask-Bearers, dream-guides able to enter others’ visions.
Territory: Mobile dune-camps, caravans, deep desert.
Relations: Welcomed by the Duskbound; wary of Chrome Ascendancy.
Mirrorborn (Homebrew Lineage)
"I was not born. I was… reflected."
PCs with this lineage are created through exposure to Carcosa — they are reflections, timelines that broke free, or "dream-versions" of people who never lived.
Appear human or elven, but something is off: asymmetrical eyes, wrong-shadowed, bleed ink.
Gain Carcosan resistances and abilities (dream-walk, illusion affinity, immunity to madness once per day).
Only 1 per party recommended.
Territory: None. They do not belong.
Relations: Universally feared. Recognized by dream-priests. Hunted by the Echoed Voice (or worshipped by it).

Magic & Religion
MAGIC IN SANDS OF THE SUNLESS REACH
"Once, magic flowed like water. Now it burns like oil, freezes like guilt, and dreams like a god who forgot its own name."
🧬 MAGICAL NATURE: Fractured, Scarce, Volatile
Magic in Diros is not a natural force anymore — it is warped, weaponized, and untrustworthy. The cataclysm that stopped the world also shattered the weave that once held reality and magic together.
Key Features:
Arcane magic is unstable and often requires mechanical conduits, ancient glyph-engines, or relics to function properly.
Divine magic is filtered through ideologies, corrupted dogma, or dream-born avatars.
Dream magic and Carcosan sorcery function outside reality’s laws — fueled by madness, identity erosion, and reflected timelines.
💡 High-Level Concept:
Magic is like electricity in a post-apocalyptic world — still usable, but only in fragments, with risk, and interpretation.
📚 WHO CAN USE MAGIC?
1. Traditional Casters (Wizards, Sorcerers, Clerics, etc.)
Still function as normal, but their origin and flavor are changed by the setting.
Wizards:
Use glyph-rigs, scrap grimoire systems, or arcane terminals instead of books.
Most belong to machine-cults, scholar-cults, or the Black Veil.
Sorcerers:
Viewed as mutants, dream-touched, or sunborn.
Their magic often has visible mutations: glowing veins, frost-smoke breath, words spoken backward.
Clerics & Paladins:
Serve ideological avatars, not traditional gods.
Their domains are deeply shaped by their faction (see below).
Must maintain symbolic purity — breaking faith corrupts or warps their magic.
Warlocks:
Often draw power from Carcosa, the Gyrosoul, or the Sun Behind the Sun.
Pact Boons are carved into flesh, dreams, or machines.
2. Psionics & Dream Magic (Homebrew/Optional)
Represented through reskinned subclasses or custom mechanics.
Often practiced by Veilmarked Drow, Mirrorborn, or the Echoed Voice.
Abilities focus on memory manipulation, non-Euclidean illusions, and scripted prophecy.
3. Technomagic
Combines arcane energy with ancient relics or machines.
Common among Scrapkin Goblins, Ironblood Dwarves, and Duskbound Engineers.
May require fuel, cooldowns, or instability checks.
🛠️ SPELLCASTING FLAVOR
Depending on your faction or source, magic looks different:
Magic Source Visuals Notes
Solar Clergy Blinding flame, golden scripture, voices in static Radiant or fire spells are filtered through sun-iconography
Black Veil Pale light, slow-motion gestures, dripping runes Spells feel too silent — as if reality holds its breath
Carcosa Masks appear mid-cast, reality flickers, deja vu May alter time, identity, or geography unpredictably
Duskbound Caravan Sand glyphs, balanced energy, musical hums Spells are woven with ritual precision to preserve balance
Chrome Ascendancy Mechanical sparks, overclocked effects, burning symbols Spells often damage the caster as much as the target
Mirrorborn Double shadows, reversed speech, reflections moving wrong Magic often bypasses normal components entirely
😱 MAGIC RISKS & MUTATIONS (Optional Rules)
Magic isn’t just power — it’s dangerous in a world so fractured. You may choose to implement the following mechanics:
Rule Effect
Flux Zones In unstable regions, magic misfires (Wild Magic Surge tables or custom effects)
Burnout Overuse of spell slots may cause magic fatigue, corruption, or hallucinations
Dream-Bleed Using too much Carcosan magic may alter your memory or appearance
Glyph-Lock Certain spells require machine-runes or ritual tokens to function
🛐 DIVINE POWERS & AVATARS
"The gods we remember are not the gods we buried."
In Diros, there are no known creator gods, but divine power persists — filtered through belief, myth, ideology, and dream.
There are no official pantheons, but instead, avatars, symbols, or powers worshipped by various factions and cultures.
🔥 MAJOR DIVINE AVATARS
🌞 The Undying Sun
Worshipped by: Solar Clergy, Chrome Ascendancy
Domains: Light, War, Order
Nature: A symbolic fusion of the eternal sun and a machine-god.
Dogma: Purity through fire. Stillness is stagnation. Heat is holiness.
“When the sun burns away the world, only the righteous will shine.”
❄️ The Frozen Thought
Worshipped by: Black Veil, some Glacierborn Elves
Domains: Knowledge, Death, Twilight
Nature: A mythic consciousness frozen at the end of time.
Dogma: Preserve the truth. Destroy the lie of warmth. Ice remembers.
“In stillness, we see. In silence, we hear.”
⚖️ The Axis That Turns
Worshipped by: Duskbound Caravan, Ironblood engineers
Domains: Balance, Time, Forge
Nature: A conceptual deity — possibly the Gyrosoul itself.
Dogma: Restore the motion. Balance the extremes. Protect the mechanism.
“Turn the wheel, and the world turns with you.”
🎭 The King in Yellow / The Mirror Sun
Worshipped by: Carcosan cults, Mirrorborn, rogue warlocks
Domains: Madness, Trickery, Knowledge (Dark), Dreams (Homebrew)
Nature: Not a god — a script, a mask, a fatal idea.
Dogma: You do not choose. You are chosen. The play has already begun.
“He does not come. He remembers.”
Mechanic: Clerics who serve the King in Yellow may receive future visions, cast dream, mirror image, or modify memory as domain spells. But they gain madness rolls as they level.
⚙️ OTHER DIVINITIES, SYMBOLIC FIGURES, AND LIES
These are local or cultural icons:
Name Role Worshippers
The Masked Prophet Alleged founder of the Duskbound Caravan Pilgrims, desert mystics
The Gear-Saint Deified engineer who “heard the voice of the Gyrosoul” Ironblood Dwarves
The Flame That Screams A literal fragment of a burning god trapped in a Chrome reactor Ascendancy radicals
The White Veil A martyr-figure whose death “froze the sunlight” Veilwardens
The Echoed Voice Possibly a future AI, god, or collective memory Radio-cults, wanderers, warlocks
Historical Ages
THE CHRONOLOGY OF DIROS
“The world has stopped turning. But the wheel of history never did.”
⚙️ ERA I: The Axis Age (~30,000 years before present)
“The world spun. The sky was blue. The gods built with hands of stone and stars.”
Summary:
The original age of motion — a time when the world spun normally, climates shifted, and a golden age of magic-mechanical civilization thrived. This was the age of the First Gyrosoul, the Axis Lords, and the Great Pacts between mortals and cosmic powers.
Key Characteristics:
High magitech: flying cities, continent-bridging skyrails, intelligent automata.
First contact with the Mirror Plane — initially seen as a harmless arcane curiosity.
Planetary equilibrium maintained by Gyrosoul, a core engine built by mortals and gods alike.
Event that Ended It:
The Sundering of the Mirror, when the Mirror Plane was breached too deeply. Something looked back.
The King in Yellow first appeared. A city on the mirror’s edge vanished.
Time trembled. Dreams began to echo.
Legacy Remnants:
Gyrosoul Vaults — sealed facilities housing forgotten technologies and pieces of the planetary engine.
Floating cities fallen from the sky, overgrown and guarded by AI-driven ghosts.
Axis Runes — language of reality-writing, etched into the walls of time-lost temples.
The Sun of Motion — a mythical fragment of the original sun, buried somewhere in the desert.
🩸 ERA II: The War of Masks (~20,000 years before present)
“The world turned. The script was written. The stage was blood.”
Summary:
As contact with the Mirror Sun intensified, mask-magic became an arcane art — a way to explore fate, memory, and persona. But over time, masks began to possess, rather than reflect. Civilizations collapsed as identity warfare erupted. Every face could be a lie.
Key Characteristics:
Rise of Scriptmages, who could rewrite fate using enchanted masks.
Entire kingdoms fell to dream-infiltration — leaders overwritten mid-speech.
Carcosa became mythologized, spreading as an idea-virus.
Time fractures began to appear — towns lived backward, cities blinked out for centuries.
Event that Ended It:
The Maskfall, when seven cities simultaneously rewrote themselves into Carcosa’s play and vanished.
The Sun stuttered, and the first signs of planetary slowing began.
Legacy Remnants:
Mask Graves — buried vaults of intelligent masks that whisper when unearthed.
Lost Scripts — reality-altering plays that, if read aloud, overwrite the present.
Echo Plagues — ruins where past versions of people still roam, unaware they died eons ago.
The Theatre Below — a subterranean city with an audience of frozen time.
🧊 ERA III: The Age of Ice and Fire (~10,000–2,000 years before present)
“The spin slowed. The world cracked. Fire met frost and neither blinked.”
Summary:
The world gradually slowed its rotation, forcing civilizations to migrate toward the twilight zone for survival. Those who remained on the day side were burned into ash-cults; those in the night froze into dream-cloistered mystics.
This was the age of mass extinction, new religions, and the birth of the Solar Clergy and the Black Veil.
Key Characteristics:
Emergence of heat and frost gods — personifications of entropy and memory.
Technomagic fractured — some fused flame with machinery; others turned to dreams and cold-stasis.
The first Masked Wars between sun and frost.
Event that Ended It:
The Death of Motion: the Gyrosoul shut down, possibly sabotaged or corrupted.
The planet stopped spinning.
One half froze. One half burned. The Shatterbelt was born.
Legacy Remnants:
Flame-Forges buried in scorched ruins — still alive, but insane.
Dream tombs where the dead sleep in frozen time, still dreaming.
War engines rusted into mountains.
Sunburst Blades and Cryohelms — relics of the divine-technological arms race.
🔍 ERA IV: The Era of Masks and Memory (~2,000 years ago to Present Day)
“The sun stopped. The shadows grew long. The past became the most dangerous thing of all.”
Summary:
The current era — defined by fragmented factions, ritualized memory, dreamborne cults, and the slow resurgence of Gyrosoul myths.
Carcosa’s whispers grow louder.
The world is stuck.
Everyone remembers a different history.
Some remember futures that haven’t happened yet.
Key Characteristics:
Major factions: Solar Clergy, Black Veil, Chrome Ascendancy, Duskbound Caravan, Carcosan Cults.
Adventurers become free agents of change, disrupting the careful balance.
Ruins stir. Dream-creatures awaken. Masks whisper of a coming final act.
Legacy Remnants (Current Campaign Setting):
Gyrosoul Shards surfacing in wasteland sinkholes.
Mirrored Suns appearing in puddles, seen only by some.
Chrono-Divers — explorers finding ruins that shift through time.
Caravan cities tracing ancient pilgrimage routes between power sites.
Ongoing Gyrosoul Resurrection Race — every faction wants the engine back… but for different reasons.
🛑 THE FUTURE ERA (Unwritten) — Act V: The Turning That Never Was
“When the play ends, only the actors remain.”
The next era is prophesied — or perhaps scripted — as Act V.
No one knows what it entails. But some claim:
The world will spin again… but not in the direction we remember.
The King will step from the mirror.
Everyone will become someone else.
Adventurers will be the final line.
This may be the end — or the beginning of the rewritten world.
🏺 ARTIFACTS & PLOT HOOKS BY ERA
Era Artifact/Remnant Adventure Hook
Axis Age Gyrosoul Core Fragment Found in a derelict sky-vault. Can power or destroy an entire city.
War of Masks Unread Script of Act III Reading it aloud begins changing PC backstories in real time.
Ice & Fire Age Sun-Chain Gauntlet A lost weapon that controls flame mechs — now in the hands of a Carcosan cult.
Mask & Memory Soul-Frozen Oracle Trapped in dream-stasis beneath a Shatterbelt ruin, speaks only in future tenses.
Act V The Final Mask A unique artifact said to grant the wielder power to “choose the ending.” Only one exists. No one knows who wears it.

Economy & Trade
CURRENCY SYSTEMS
There is no universal currency. Diros is too fractured, ideologically divided, and hostile to sustain a centralized economy. Instead, regions and factions use localized currencies, bartering, and resource-based trade.
🔧 Trade Standard: “Scrip”
Issued by Sanctum Veloce and adopted in most of the Shatterbelt.
Small metal rectangles (like dog tags) stamped with gyro-inscribed seals.
Backed by stored arcane energy (glows faintly when whole).
Accepted in most neutral or Duskbound settlements, but often rejected in zealot territories.
1 Scrip is roughly equal to a D&D gold piece, but value is fluid based on scarcity and region.
⛽ Fuel Shards
Shards of refined arcane oil, essential for powering machines, rigs, or spell-tech devices.
Common currency among Chrome Ascendancy, Scrapkin, and warlords of the Wastes.
Can be used as currency, barter, or literal power source.
Comes in vials, cubes, or crystalline rods.
1 Fuel Shard ≈ 10–25 scrip (in vehicle-centric areas).
❄️ Frostglass
Slivers of psychically resonant ice harvested from Lake Hali or the Cracked Dome.
Used by the Black Veil, psychics, and dream-cults as both currency and ritual material.
Stores thoughts or visions if properly etched.
Illegal in Chrome territory (possessing it = heresy).
1 Frostglass sliver ≈ 50–100 scrip, but dangerous to carry unshielded.
📜 Echo Credits
Broadcasted barter tokens traded through radio signal, used by Echoed Voice loyalists.
Cannot be held physically — exist as encoded phrases or spoken deals.
Tied to radio towers; some have dangerous backdoors (“debt recalls”).
Used by shadow traders and info-brokers.
⚖️ Barter & Sacred Trade
Still the most common method of commerce, especially in the Reach and Wastes. Water, weapons, medical supplies, relics, machine parts, food, dreams, and labor are all valid currencies depending on context.
A rusted water filter may be worth more than a bag of diamonds.
🛤️ 2. TRADE ROUTES
"The world no longer spins — but the wheels of trade do."
Despite the chaos, trade still flows between the three major zones — often through mobile cities, guarded convoys, and smuggler skims. These routes are dangerous, political, and full of opportunities for adventure.
🚚 The Spine Route (Shatterbelt Trade Artery)
Connects Sanctum Veloce to Duskbound enclaves, nomad camps, and the Black Spiral ruins.
Mostly overland convoys or sand-skimmers.
Attacked frequently by Chrome raiders, sand beasts, and bandit-cults.
Key Trade Goods:
Fuel shards
Water casks
Machine parts
Medical fungus (cultivated in the Shatterbelt's few bio-domes)
🔥 The Furnace Path (Burning Wastes Route)
A high-risk smuggler road into Scorchspire, through Rattlemaze and Chrome territory.
Open only during the “cool hours” (twilight), and guarded by fire-zealots.
Often used for weapon smuggling and black-market relic trade.
Key Trade Goods:
Flame-reactive metal
Solar scripture pages (forgeries and originals)
Sunforged weapons
❄️ The Pale Drift (Frozen Reach Convoy Route)
Ice-rail and sledge routes across the glacial bridges to the Veil monasteries and Lake Hali.
Frequently disrupted by froststorms, psychic anomalies, and Frostwrought raids.
Often requires passage through Carcosa-bleed zones.
Key Trade Goods:
Frostglass
Dream-lanterns (contain navigable dreams)
Lost knowledge (memory glyphs, lore scripts)
📻 Echo Routes (Secret Dream-Networks)
These are non-physical trade routes: dream-pacts, info-pirates, and radio-delivered contracts.
Used by information smugglers, Carcosan infiltrators, and the Echoed Voice itself.
Dangerous — sometimes cost more than they're worth.
Key Trade Goods:
Blackmail secrets
Prophecy fragments
Scripted futures
🏙️ 3. ECONOMIC ZONES & TRADE CITIES
🛞 Sanctum Veloce

Uses scrip, but accepts all other currencies at negotiated rates.
Markets: Chrome Bazaar, Coil Exchange, Bone Auction Hall.
Legal and illegal trade exist side-by-side, monitored by Governor Thorne’s “Burnt Coin Guard.”
❄️ Penance Spiral
Home to undead traders, frostbound mystics, and dream-pact merchants.
Trades in frostglass, philosophy, and soul fragments.
High risk — trades often include memory forfeiture or dream services.
⚖️ Ten Thousand Path Camp
Nomadic but stable economy; favors balanced trade, fair exchange, and ritual bargaining.
Uses scrip, barter, and sacred tokens.
Overseen by Trade-Saints, who memorize every deal ever made in the camp.
🔥 Scorchspire Markets (Controlled)
Closed market city under Solar Clergy control.
Only sun-approved trade is allowed — mostly fuel, weapons, armor.

🎭 Mask Markets (Illegal, Mobile)

Only those who bear a dream-token can access them.
Trade in masks, scripts, forbidden magic, lost names, and prophecy.
🧠 4. TRADE FACTIONS & GUILDS
⚙️ The Coil Exchange
Relic-hunters and antique engineers who trade in ancient machine parts, spell cores, and Gyrosoul fragments.
Neutral but heavily watched by Chrome and Black Veil.
Trade is handled via contract-oaths, enforced by glyph-scribes.
🛡️ The Rattle Kings
Warlords of the Wastes who protect or raid convoys.
Will trade protection for tribute — or take tribute by force.
Recognizable by their bone-studded armor and rig banners.
🧵 The Silken Sigil
Discreet caravan guild that deals in non-material goods: dreams, memories, identities, and fate-stamps.
Members always wear veils or illusion masks.
True origins unknown — may be tied to the King in Yellow.
⚔️ 5. CAMPAIGN OPPORTUNITIES FROM ECONOMIC SYSTEMS
Scenario Hook
Caravan Escort Protect a critical fuel shipment across the Spine Route while evading Chrome raiders and Carcosa cultists.
Market Intrigue Infiltrate a forbidden Mask Market to retrieve a stolen prophecy scroll — but beware, your reflection may try to kill you.
Currency Collapse Sanctum Veloce’s scrip stockpile has been counterfeited using dream magic — can the players find the source before the economy implodes?
Trade War Broker peace between the Duskbound and Chrome smugglers… or ignite a trade war that burns half the Wastes.
Auction of Forbidden Names A name belonging to one of the PCs is up for auction in a dream-bazaar — and whoever buys it can rewrite their past.
✅ SUMMARY: ECONOMICS AT A GLANCE
System Notes
Scrip Arcane-tagged metal tokens, default Shatterbelt currency
Fuel Shards Currency and fuel, highly valued in Wastes
Frostglass Dream-trade currency, dangerous, valuable
Echo Credits Broadcast economy used by Carcosa-friendly traders
Barter Still the most reliable method of trade
Trade Routes Often controlled by factions, ripe for conflict
Black Markets Operate under dream laws and mask rituals
Law & Society
THE RULE OF LAW IS FRACTURED
There is no universal legal system in Diros. Instead, each major power enforces its own doctrine of justice — shaped by their culture, gods (if any), and perception of order.
Justice is administered in ways that reflect their philosophy of survival.
🏛️ SYSTEMS OF JUSTICE BY REGION / FACTION
🔥 Solar Clergy (Burning Wastes)
Law Is: Flame. Sin Is Heat That Does Not Rise.
Justice is religious dogma, enforced by Sun-Inquisitors.
Courts are theatrical rituals — public confessions, followed by symbolic immolation or purification.
Heresy (including contact with Carcosa, the Mirror Sun, or the Frost) is punishable by death by light.
Merciful “sentences” involve branding, exile into the Wastes, or conversion into Sunbound servitude.
Execution Method:
Solar lens-beams, burning masks, or sentencing to the Furnace Pits.
View of Adventurers:
Tolerated if useful, especially if aligned with the flame.
Treated as expendable firewood: burn bright, die clean.
Heretical adventurers are branded “Twilight Seeds” and hunted.
❄️ The Black Veil (Sunless Reach)
Law Is: Memory. Sin Is Falsehood.
Justice is administered by Mind-Seers, who extract true memories and cross-reference identity threads.
Trials take place inside Dream Rooms, where participants re-live events — watched by Veil Scribes.
Punishment for lies is erasure of memory, rewriting of identity, or imprisonment in stasis-dreams.
Execution Method:
Dream-sealing (being written out of memory), neural freezing, or casting into Lake Hali.
View of Adventurers:
Regarded with cautious respect, especially those with dream immunity.
Adventurers are seen as unreliable narrators — watched, but rarely trusted.
Some are used as “Wild Factors” — unpredictable pieces in strategic dream-games.
⚙️ Chrome Ascendancy (Machine-Enforced Wastes)
Law Is: Code. Sin Is Error.
Justice is technocratic — crimes are logged by data-scribes, tried in logic courts, and enforced by Iron Judges (constructs).
All citizens are tagged with compliance runes at birth; adventurers are foreign objects and must register.
Trials are swift, emotionless, and algorithmic.
Execution Method:
Reprogramming, neural reconditioning, brainburn, or recycling into parts.
View of Adventurers:
Considered useful anomalies.
Allowed limited rights under “Wanderer Protocols” if they carry proper certifications.
Unauthorized casters are seen as wildcode and marked for purge.
⚖️ Duskbound Caravan (Shatterbelt)
Law Is: Balance. Sin Is Imbalance.
Disputes are handled by ritual tribunal, often with symbolic acts of restitution.
Offenders may pay in oaths, dreams, or service — sometimes even blood-weighing, where your blood is measured for truth.
Serious crimes are tried by Trade Saints, memory-bound judges who never forget any contract.
Execution Method:
Exile, balance duels (ritual combat), memory-branding (you carry a mark that tells your crime).
View of Adventurers:
Treated as outside the system, but respected if they honor their word.
Seen as instruments of imbalance or correction.
Invited into “deed-pacts” — where an adventurer’s action becomes part of the law.
🛞 Sanctum Veloce (Mobile Trade Metropolis)
Law Is: The Wheel Turns. Sin Is Rust.
Justice is mercenary and transactional — handled by the Burnt Coin Guard, city-enforcers bound by debt-oaths.
Crimes are punished or forgiven based on economic impact — steal food? Death. Steal relics? You’ll be promoted.
Trials are rare. Bribes are common. Justice is a gear in the machine, not a virtue.
Execution Method:
Rig exile (forced to walk the Wastes), chain-collars, explosive obedience runes.
View of Adventurers:
Celebrated if they stimulate the economy (e.g., sell relics, win fights, protect trade).
Feared if they disrupt power structures.
“Famous” adventurers may become media icons — or targets.
🗡️ JUSTICE IN THE WILDS
Outside of structured zones, justice is administered by:
The sword
The pack (caravans)
The coin (bribes)
The story (reputation)
In lawless areas — caravans, nomad camps, bandit strongholds, or cursed zones — justice is tribal, personal, or violently symbolic.
A dream-theft might be punished by stealing a year of your memories.
Killing a loved one might invoke a bone duel, where your enemy gets your skeleton after death.
🔎 CRIMES THAT MATTER IN DIROS
Crime Common Punishment
Dream Corruption (e.g., planting false memories) Dream erasure / brain-burn / exile
Unauthorized Carcosa Worship Burning, dream-prison, or memory deletion
Theft from a Trade Saint Blood-forfeit or oaths for seven generations
Mask Wearing (Unlicensed) Public unmasking (painful), or reflective execution
Casting Near a Gyrosoul Relay Treated as sabotage or heresy depending on region
Killing a Veil Seer Echo Exile: forced to relive your crime forever in loop-space
⚔️ ADVENTURERS: HEROES, MERCENARIES, OR THREATS?
"Adventurers are like sandstorms. Sometimes they clear the rot. Sometimes they bury a town alive."
Adventurers are:
Feared by structured governments (especially the Clergy and Chrome).
Watched by intelligence networks and spy-factions.
Exploited by trade cities, who treat them like celebrity gladiators.
Revered by the desperate — especially in remote ruins, nomad camps, or outposts where help never comes.
Their reputation is currency.
🎭 Titles Adventurers May Earn
Title Meaning
Sandwrought A survivor of Wastes trials. Often feared or respected.
Balancebreaker Someone who disrupted a major economic or ideological power.
Scripted One Someone believed to be written into the Carcosan play. Dangerous. Watched.
Gyrosoul-Touched A rare mystic — often worshipped, hunted, or both.
Dreamgutter One who has severed Carcosan dreams from others — often revered by the Black Veil.

Spread through masks, dreams, and “auditions.”
Use mirror portals, identity theft, and scripted events.
Leaders:
Director of Act IV – masked being with time-altering powers.

🔻 The Axial Heresy
"The world spins. The world bleeds. Make it bleed again."
Believe the Gyrosoul is a living god, imprisoned by the sins of civilization.
Want to “bleed the world into motion” — a cataclysmic ritual of rotation that would destroy the Shatterbelt entirely to restart planetary spin.

Use gravitational weapons, magnetic implosions, and ritual quakes.
Secretly infiltrating Duskbound communities with glyph-priests.
Leader:
The Bearing – a floating robed figure, always spinning, who speaks in mechanical clock-chimes.
