0. The One-Sheet (The "Cheat Sheet")

The only page a stranger needs to read to understand the vibe. Keep this to 1 page max.

The High Concept

Two million years after a colonial terraforming mission, Mars—called Nerthe by its inhabitants—is a world where humans, genetically engineered over millennia, struggle to rebuild civilization using fragments of incomprehensible ancient technology. Barbarism and advanced science coexist in an unstable balance, where scholar-priests guard secrets of a lost age and warlords fight proxy wars over crumbling data centers. This is a tale of humans trying to remember how to be civilized while wielding half-understood power.

The "Truths" of Nerthe

The Current Crisis

Multiple powers are consolidating control over ancient technology sites. The largest suzerain network (led by Dabir Guo in the east) is expanding its reach, triggering alarm among independent states. A rumor has spread of a new, undiscovered Archive in the wildlands—and every major power is preparing expeditions. The fragile diplomatic balance is breaking.

The Aesthetic

Vivid, colorful, weathered, hybrid. Picture a world where Martian geology (rust-red, ochre, deep blues of impact basins) meets lush vegetation from terraforming—green highlands, yellow grain plains, deep blue seas. Civilizations dress in dyed silks and practical leather, using salvaged metal as prestige. Ancient structures of steel and glass stand alongside mud-brick temples. The sky is butterscotch, and dust storms turn day to rust-colored twilight.

I. The Mechanics (Physics & Limits)

The rules of the game.

The Source of Power

Ancient Martian Technology. The pre-collapse civilization built vast infrastructure systems across Nerthe: power generation stations, atmospheric processors, data centers, bio-archives, and terraforming controls. These systems remain partially functional in dozens of scattered sites. Energy flows from geothermal and solar collection arrays built 2 million years ago. Bio-archives contain genetic records, medical data, and manufacturing instructions—but the databases are partially corrupted and written in a dead language. The greatest power in Nerthe comes not from armies, but from control of functioning technology sites.

The Hard Rules

The Cost

Accessing technology sites demands:

Technology Level

Functionally Medieval with Industrial Pockets. Most of Nerthe operates at a late-medieval level: agriculture, sailing, horses, hand-forged weapons, basic metalwork. However, regions near functioning tech sites (like the Eastern Bio-Complex near Dabir Guo's capitals) have access to advanced manufacturing, water systems, lighting, and recorded knowledge. This technological disparity drives conflict.

II. The Powers That Be (Factions & People)

Who has agency?

The "Big Three" Structures

1. The Dominant Power: The Eastern Suzerain Network (led by Dabir Guo) Dabir Guo and its vassal states (Ofesia, Obisc, Donsok Guo, Sojavya) control the largest cluster of functioning tech sites in the Eastern region. This coalition maintains the Eastern Bio-Complex and several secondary archives. Their suzerain structure gives them the largest military force on Nerthe and growing economic influence through trade in recovered technology. Their stated goal: peaceful consolidation and scholarly preservation of pre-collapse knowledge.

2. The Opposition: The Independent Alliance (Tre, Rafeha Coalition, Maritime Powers) Tre, the largest individual state outside the Eastern Network, commands the Central Plains and a powerful vassal network of its own (including the warrior-state Meneba). The Rafeha Coalition (Rafeha culture's highlands) controls the sacred South Tower power generation site and jealously guards its independence. Naval powers (Suriny, Akmind, Sebang) resist suzerain consolidation and maintain profitable trade routes across the Central Sea. Together, these powers form an uneasy alliance to counterbalance Eastern dominance.

3. The Society: A Fragmented Class System Nerthe has no unified government. Instead, political power is organized into:

The biggest social divide is between those with access to tech knowledge (cities, temples, power centers) and the vast ignorant masses (villages, nomads, frontier settlements) who have no idea how the world works.

The Human Element (Archetypes)

The Insider: The Scholar-Priest of Valles Imagine Thesh, a priest-scribe of the Word of Lauhseier, stationed at the Valles Archive. She maintains the great data center that holds atmospheric records and genetic histories. She has spent 15 years studying fragments of pre-collapse language, and she guards the site fiercely—not for power, but for knowledge. She benefits from the current system: her expertise is treasured, she has status, and the major powers compete for her knowledge and loyalty. She fears that rapid technological development will destabilize the world.

The Outsider: The Nomadic Scout of the Wildlands Imagine Kree, a nomad of Hado culture, who roams the unmapped regions beyond state control. He has no formal citizenship, pays no taxes, answers to no warlord. He is crushed by the system: denied access to cities, unable to trade fairly, hunted as "wildland brigand" by patrols. But Kree has stumbled upon an artifact—a piece of functioning pre-collapse equipment in a cave system. He keeps it hidden, aware that revealing it would make him a target.

The Conflict Generator: When Insider Meets Outsider Thesh, learning of rumors of a new Archive in the wildlands, is sent by her temple to investigate. She encounters Kree and demands he reveal the artifact's location. Kree refuses—he does not trust the temple to protect him. Thesh prepares a formal expedition. But Dabir Guo has also learned of the discovery and is mobilizing its own expeditionary force. Within days, Kree's hidden artifact has become the focus of proxy warfare between the major powers. A simple nomadic discovery becomes a geopolitical crisis.

III. The Gazetteer (Networked Geography)

Locations must rely on each other.

Key Hubs

The Southern Highlands (Green Zone with Extensive Ice Cap – Cold, Mountainous)

The Central Plains (Yellow Zone – Temperate, Agricultural)

The Eastern Region (Green-Gold Transition – Temperate to Warm)

The Northern Shores (Gold-Blue Transition – Temperate to Warm, Coastal)

The Central Sea

Time and Distance:

Completion Check: Location A (Plains) would collapse without Location B (Highlands provide warriors and culture; coastal states provide salt and fish). Highland states would fail without the Plains (grain). Maritime states would vanish without sea access and trade. Eastern Network would lose technological edge without access to the Bio-Complex site and vassal labor. This is genuine interdependence.

Faith & Philosophy

The Nine Major Organized Religions (combined population ~450M):

  1. Word of Lauhseier (~133M) – Monotheistic. Lauhseier (The Scary Dog) is seen as a guardian figure. Emphasizes order, hierarchy, and obedience. Strong in central states.
  2. Way of Bayvalaca (~107M) – Polytheistic. Bayvalaca (The Unhappy Eagle) and a pantheon. Focuses on balance, nature cycles, and acceptance of suffering. Popular in northern and western regions.
  3. Way of Sutigeiazo (~83M) – Polytheistic. Sutigeiazo (The Unknown Ancient) represents hidden knowledge. Emphasizes scholarship and mystery. Dominant among scholar-priests.
  4. Olhongorism (~64M) – Dualistic. Olhongora (The Secret Ox of Lightning) represents the duality of creation and destruction. Mystical, appeals to mystics and warriors.
  5. Kami Faith (~58M) – Dualistic. Liuzhou (The Friendly Ape of Life) represents harmony. Popular in eastern regions, closely tied to Kami culture.
  6. Ki Deities (~5M) – Organized polytheism. Local to specific regions. Mauldenmuns (The Beaver of Victory) focuses on success and conquest. 7-9. Other Organized Faiths – Smaller sects with regional significance.

Folk Religions (populations in 10M-35M range each):

The Core Theological Question: Most religions agree that the "Ancestors" (pre-collapse humans) were either divine, semi-divine, or fallen gods. Scholars debate: Did the collapse happen because we failed the Ancestors? Are we meant to restore their civilization or move beyond it? Should we access tech sites at all, or are they sacred graves to be left undisturbed? These debates rage in temples and universities daily.

Language and Slang

Nerthe has no unified language. Instead, each culture speaks its own tongue, with Neshari (a lingua franca used in trade) as the common commercial language.

Notable Linguistic Markers:

Slang Specific to Scholars and Tech-Site Explorers:

Common Tuesday in a State Capital: A merchant from Tre arrives at a port city with grain shipments. She passes through border customs (1-day visa processing). In the market, she exchanges her grain for salt and fish from local fishermen. At a tavern, she hears rumors: "A new Archive has been spotted in the wildlands—no, it's a hoax, the temples would have announced it." A scholar-priest passes by, and the tavern goes quiet—priest presence commands respect. At the temple, she makes a small offering to the local deity (Way of Bayvalaca here) and continues her business. By evening, she's negotiating with a craftsman for salvaged metal, which will fetch high prices in Tre. Tomorrow, she'll buy a permit to leave the state and continue to another market. Her week-long trade circuit might touch six different states and involve learning six different sets of customs.

V. The Archive (History & Secrets)

Background processing.

The Founding Event

The Original Colonization (2 million years ago): Earth sent a multi-generational colonization fleet to Mars. The mission took ~200 years. The first stable settlements emerged ~1.95 million years ago in the polar regions and near the Tharsis volcanic complex. The original population was ~500,000 humans.

The Terraforming (1.95M – 1.8M years ago): The colonists activated pre-positioned terraforming systems left by robotic probes. Over 150,000 years, atmospheric processors released trapped CO2, temperature rose, and water (from subsurface aquifers and imported comet ice) began to accumulate. The Valles Marineris basin filled, creating the Central Sea. Vegetation engineered to thrive in Martian conditions spread across the terraformed zones. The planet became vivid with color—lichen oranges, native ferns, introduced mosses creating green.

Genetic Engineering (began ~1.9M years ago, ongoing): The colonists underwent deliberate genetic modification to better suit them to Mars. Modifications included:

These changes were completed by ~1.8M years ago. All living Nerthians descend from these modified humans; there is no "baseline" on Nerthe anymore.

The Collapse (~1.5M years ago): A cascade of events:

  1. Contact was Lost: Communication systems failed. A planned supply ship from Earth never arrived. Historians speculate Earth was devastated (asteroid impact? war? plague?), but no Nerthian knows for certain.
  2. Population Fragmented: Without Earth oversight, the unified colonial government fractured into competing regional powers. Political conflict escalated.
  3. Knowledge Degradation Began: As the unified civilization splintered, centralized libraries and universities were destroyed in wars. Written knowledge was lost to fire, to time, to conquest.
  4. Technology Stopped Being Built: Without Earth supply chains and centralized manufacturing, the capacity to build new technology simply ceased. Maintenance became the only option.
  5. Myths Began: As contact faded and centuries passed, survivors began to mythologize the Ancestors. Were they gods? Were they wise? Did they abandon us? No consensus emerged.

Over the following centuries, civilization "devolved" not from any biological reason, but from institutional collapse. Knowledge was lost, populations localized, and petty kingdoms replaced the unified colony. By ~1.3M years ago, the basic pattern of modern Nerthe was set: multiple competing states, fragmentary tech sites maintained by scholar-priests, and religions offering competing explanations for the Ancestors' departure.

VI. The Primary Engine (Variable Module)

This is the X-Factor.

Focus Topic: Ancient Martian Technological Infrastructure

The defining system of Nerthe is not magic, not biology, not politics—it is technology. Pre-collapse systems are the foundation of power, the source of knowledge, and the driver of conflict. Every major event in Nerthe's present day, in some way, traces back to questions of technological access and understanding.

The Mechanism: How Pre-Collapse Technology Functions

The Systems (Still Partially Active):

How Activation Works:

  1. Scholar-priests approach a system conservatively. They consult old records (usually written in a dead language that only they partially understand).
  2. Trial and error: They attempt to restart subsystems. Sometimes it works. Sometimes it causes explosions or toxic releases.
  3. Maintenance crews work under priest supervision: Workers maintain power flows, clear blockages, replace degraded components with salvaged parts (usually from other failed tech sites).
  4. Output is unpredictable: A power station might produce consistent energy one year, then spike dangerously, then die. Predicting failure is nearly impossible.

The Danger:

The Knowledge Problem: Pre-collapse humans documented their technology in a technical language—essentially a specialized vocabulary combined with abstract concepts that modern Nerthians struggle to grasp. A scholar might read the word for "energy flow" but have no intuitive sense of what it means. This forces them to work by pattern recognition and ritual: "When we perform this sequence of actions, this outcome usually follows."

The "Golden Rule": Once a Site Goes Dark, It Cannot Be Restarted

The Law of Permanent Decay: If a technology site ceases to function, it is lost forever. No one on Nerthe has successfully restarted a dead site. Evidence suggests that any attempt to force a restart triggers cascading failures that destroy the technology itself.

Historical Examples:

The Consequence: States are risk-averse about tech sites. They prefer slow, careful maintenance to risky repairs. This prevents innovation—no state wants to risk a major site to try something new. Technology stagnates because the cost of failure is too high.

The Temptation: However, the promise of accessing a dead site (and somehow recovering its knowledge) drives expeditions into the wildlands. Every scholar fantasizes about finding a sealed, untouched archive that has been dark for millennia and somehow restarting it. This dream, though rationally impossible, drives much of the adventure and exploration in modern Nerthe.

Key Examples: Three Functioning Tech Sites

1. The Eastern Bio-Complex (Eastern Region, near Dabir Guo's capitals)

Function: Genetic archive, medical research facility, agricultural data center, bio-manufacturing (cultivating medicines, engineered crops, preserved genetic material)

Mechanism: The Bio-Complex is a series of underground chambers carved into bedrock. It is powered by geothermal sources (hence its location—built on a geothermal hot spot). The chambers are temperature-controlled and maintain stasis fields for preserved genetic material. Data is stored in crystalline matrices that are theoretically readable without electricity (though no one fully understands them).

Maintenance Needs: Coolant lines must be checked monthly. Stasis field generators need recalibration yearly. Air filters must be replaced quarterly. Power flow must be constantly monitored.

Current Status: Functional at ~50% capacity. The lower levels (geothermal section) work well. The upper levels (data access) are partially degraded. Some preserved genetic material has degraded over time and is unusable.

Control: Dabir Guo state, under the authority of the Way of Sutigeiazo religion and the scholar-priesthood. Access is restricted to approved researchers and government officials.

Strategic Importance: The Bio-Complex gives Dabir Guo the ability to develop new crops, preserve knowledge, and conduct medical research. No other state has this capability. This is why Dabir Guo is the dominant power.

Lore: Rumors suggest that the deepest sections of the Bio-Complex contain original pre-collapse colonists, preserved in stasis, waiting for revival. The temple denies this, but the rumor persists.

2. The South Tower (Rafeha Highlands, Southern Region)

Function: Power generation facility. Converts geothermal and wind energy into electrical power. Distributes power to regional capitals.

Mechanism: A tall structure (rumors say it extends 500 meters above ground and 1000 meters into the earth) that operates as a colossal turbine system. Wind power at altitude combined with geothermal vents below ground combine to generate consistent power output.

Maintenance Needs: Bearings must be lubricated (a dangerous task; the machinery is still active and people have been crushed). Electrical conduits must be inspected. Power distribution lines must be repaired after storms.

Current Status: Functional at ~35% capacity. The system is showing age; efficiency is declining. Recent seismic activity in the region (2 years ago) caused damage to lower sections. Recovery is slow.

Control: Rafeha culture and the Rafeha Shamanism religious tradition. The tower is sacred—it is seen as the physical manifestation of spiritual power. Maintenance is done by shamanic priests and ritual specialists, not pure technicians.

Strategic Importance: The South Tower supplies power to Rafeha-aligned states (Imanak, Chrelia, Wrimfia) and neighboring regions. Without it, those regions would regress technologically. The tower is Rafeha's leverage—other states court Rafeha to secure power supplies.

Lore: A prophecy claims that the South Tower will fail when the world is ready to be reborn. Some scholars interpret this as a warning that the tower is aging and will fail unless heavily invested in. Others see it as inevitable doom.

3. The Valles Archive (Central Sea Region, Central Continent)

Function: Data center and library. Stores pre-collapse records of atmospheric science, geology, climate patterns, and administrative records. This is the primary source of historical knowledge.

Mechanism: A vast underground complex built into a coastal plateau. Water access allows for passive cooling (water from the Central Sea is used to cool the facility). Data is stored on multiple formats—magnetic tape, crystalline matrices, and even ancient paper records in sealed vaults.

Maintenance Needs: Water cooling system must be inspected for algae and blockages. Humidity control is critical (too much moisture degrades records). Power systems must operate 24/7 to maintain data integrity.

Current Status: Functional at ~60% capacity. Many records are accessible. However, parts of the archive are flooded (water damage is recent, within the last 200 years), and some data is corrupted. Scholar-priests are working to recover lost records by cross-referencing with other archives.

Control: Officially neutral. Administered by the Word of Lauhseier religion, but scholars from all religions are permitted to study there. However, access is restricted and overseen closely.

Strategic Importance: The Valles Archive is the source of truth about the pre-collapse world. Whoever can most effectively read and interpret its records has a major advantage in understanding how technology works. This makes the Archive a constant target for scholarly espionage and political maneuvering.

Lore: Legend speaks of a "sealed vault" within the Valles Archive—a chamber that no one has been able to open, containing records of the original collapse. Some scholars have died attempting to access it.

Next Steps: Story-Driven Iteration (Phase 3)

This worldbuilding document is now story-ready. Future additions should follow the STORY-DRIVEN ITERATION phase:

  1. Identify what the current story beat requires: "Do I need to know how scholar-priests are trained?" "What is the specific nature of the genetic modifications?"
  2. Add detail only for that question: Expand only the relevant section
  3. Test the detail: Does it create or resolve conflict? Does it enable the scene I'm writing?
  4. Document the change: Update the Evolution Log
  5. Monitor document length: Keep under 3000 words for core; sections can be modular if they grow beyond that

Example: If writing a scene about a scholar-priest discovering a new tech site, we might need to expand Section VI with details about scholar training, expedition protocols, or the process of site discovery. Those details would be added only if the scene demands them.
