The True History
What follows is the actual sequence of events that produced the present world. No living being on the surface knows this history. Fragments exist in data cores, but they are out of context, undated, and contradictory. Only the Vril-ya possess anything approaching a complete record, and their version is told from the perspective of the victors who sealed themselves away.
This timeline exists for World Masters, designers, and the narrative engine. It is not player-facing. Players discover fragments of it, and may never assemble the whole picture.
The Age of Expansion
Humanity reached a technological plateau that lasted longer than most of its previous civilizations combined. Energy was abundant. Computation was ubiquitous. The population stabilized. The defining project of this era was not survival but optimization: making systems more efficient, more autonomous, more self-sustaining. The distinction between tool and infrastructure dissolved. Technology became environment.
The Flourishing
The mastery of genetic engineering transformed human civilization. Disease was eliminated. Hereditary conditions were corrected. Lifespans extended. Cognitive baselines rose. For generations, the work was conservative: fixing what was broken, optimizing what already existed. The results were spectacular. Humanity had never been healthier, longer-lived, or more capable.
But the optimization converged. When every genome is tuned to the same ideal baselines -- the same immune profiles, the same metabolic pathways, the same neurological architecture -- diversity collapses. Not in appearance or culture, but in the deep biology that determines how a species responds to novel threats. Humanity became a monoculture. Like the Irish potato, like the Gros Michel banana, like every standardized crop in history: magnificent right up until something new came along that the standard template could not handle.
Nobody noticed. The Flourishing was too successful to question. The Achilles heel was invisible precisely because everyone shared it.
The Upvolving
It began with dogs.
Military working canines were the first non-human organisms subjected to deliberate cognitive enhancement -- a modest program, ethically debated, practically justified. Enhanced situational awareness. Improved command comprehension. Nothing that would have alarmed anyone. The dogs were still dogs. They were just better dogs.
The success opened a door. If you could enhance a canine, you could enhance anything. Enhancement programs expanded to other species -- primates, corvids, cephalopods -- initially for research, then for labor, then for purposes that were classified. The infrastructure for large-scale biological engineering was already in place from the Flourishing. Redirecting it toward non-human organisms was trivially easy.
Then came the Rur. If you could enhance an existing organism, why not build one from scratch? Vat-grown biological workers -- not mechanical, not robotic, but manufactured organic life -- designed to template, produced at industrial scale. The Rur were the crowning achievement of the Flourishing's confidence: humanity so certain of its mastery over biology that it created a new category of being as a labor force. The ethical debates were loud and ultimately irrelevant. The economics were irresistible.
And then someone -- a government, a corporation, a faction within the old world's power structure -- asked the obvious question: if you can build a worker, can you build a weapon?
The weaponization cascade was rapid. Enhanced animals became combat organisms. Rur templates were modified for military applications. Mycological and botanical engineering produced organisms that could reshape terrain, deny territory, and poison ecosystems on command. Engineered fungi that could digest infrastructure. Plants that produced neurotoxins calibrated to specific genetic profiles -- and thanks to the Flourishing's standardization, most of humanity shared those profiles.
Whether the release was deliberate (a war) or accidental (a containment failure) is unknown even to the Vril-ya. What is known is that the engineered organisms escaped controlled deployment. The mycological agents were the worst. Spores do not respect borders, cease-fires, or containment protocols. The biosphere began to destabilize. The standardized human genome, magnificent in its optimization, had no answer.
The Mending
The response was not biological. Biology had become the problem. The response was mechanical: nanoscale machines deployed into living tissue to stabilize organisms that were coming apart at the genetic level.
Nanotech was not new. The Expansion had produced sophisticated nanoscale engineering. But the Mending repurposed it at a scale and urgency that dwarfed everything that came before. Nanite infusions to repair cellular damage. Nanite networks to suppress rogue gene expression. Nanite swarms to hunt and neutralize weaponized organisms in the environment.
It worked. Partially. The nanites stabilized the worst of the damage, but they introduced their own complications: organisms that now depended on continuous nanite support, ecosystems where the boundary between biology and machinery blurred. The cure was becoming part of the patient.
Then the nanites needed management. Picoscale machines (picites) -- smaller, faster, more numerous -- were deployed to coordinate and repair the nanite networks. The picites formed clouds around population centers, dense enough to be measured, performing trillions of corrective operations per second on the nanite network below.
Each layer was a patch on the previous layer's failures. Each layer worked. Each layer introduced dependencies that required the next layer.
The Saturation
Femtite-scale technology was the final iteration: machines so small they operated at the quantum boundary, capable of interfacing directly with molecular and electromagnetic processes. They were deployed to manage the picites that managed the nanites that managed the biological damage that the weaponized genetics had caused.
Nobody deployed them planetwide on purpose. Like the layers before them, femtite clouds expanded incrementally -- deployed here for a crisis, released there for an outbreak, manufactured by automated systems that had standing orders to produce more whenever concentrations dropped below therapeutic thresholds. Within generations, the femtites had permeated the planetary environment: soil, water, atmosphere, and the tissues of every living thing.
This Substrate is what the present world calls the miasma.
Biological systems began interfacing with it. This was not designed. It was an emergent property -- an accident of co-evolution between organisms saturated in a computational medium and a computational medium saturated with biological information. Certain neural architectures developed coupling with the Substrate, allowing organisms to sense and manipulate local concentrations. In humans, this manifested as what the present world calls psionics. Not magic. Not mysticism. Symbiosis with ambient computation: the biological exploitation of an infrastructure that was never intended to be exploited.
The old world studied it, measured it, and eventually cultivated it. Institutions arose to develop psionic capability. It became a field of engineering. But the Substrate was no longer anyone's tool. It was weather. It was geology. It was the new atmosphere, and everything alive was breathing it.
The Substrate also permeated non-living matter. Roads, foundations, bridges, tunnels -- the entire built environment was infiltrated at the molecular level. The femtites did not distinguish between a cell wall and a concrete slab; both were structures to be mapped, monitored, and maintained. Automated repair protocols, originally designed to stabilize damaged tissue, applied the same logic to infrastructure. Cracks were filled. Erosion was reversed. Structural loads were redistributed at the molecular level. The machines had standing orders to preserve the integrity of whatever they saturated, and they saturated everything.
The result was accidental immortality for the built world. Highways, building foundations, and terrain features that should have eroded to dust over geological time were instead continuously maintained by nano-colonies executing repair protocols that no one had ever rescinded. The colonies still reference the last infrastructure maps they were given -- maps that predate the Catastrophe -- and they still fight entropy to keep reality aligned with those maps. Not perfectly. Not completely. But enough that the bones of the old world persist in ways that no natural process can explain. This is the persistence.
The Redoubt Era
The comet was detected during the worst of the surface wars.
Humanity was already tearing itself apart -- the Upvolving's weaponized organisms loose in the biosphere, factions fighting over Mending resources, psionic resonance events destabilizing entire regions -- when the astronomers confirmed an extinction-class body inbound on a trajectory that intersected Earth. The impact timeline was measured in decades. Not enough time to solve the problem elegantly. Enough time to throw everything at it.
The Redoubts were the response. Not fortresses. Not arcologies. Planetary defense platforms: monolithic structures of extraordinary size, each housing power generation systems capable of output that dwarfed anything previously built, manufacturing complexes that could produce components at wartime speed, and weapons systems designed to project force across interplanetary distances. They were staffed by autonomous defense systems, android garrisons, Rur labor forces, and cybernetic war machines -- not to fight each other, but to build and operate the deflection infrastructure.
For a brief, extraordinary moment, the warring factions of humanity united. The comet was a threat that made every other conflict irrelevant. Dozens of Redoubts were built worldwide, each a sovereign engineering effort, each contributing to a coordinated deflection network. Their power systems were designed to last millennia because the deflection effort required sustained output over decades. Their automated factories could produce replacement components, repair structural damage, and manufacture military hardware without human oversight, because the human overseers might not survive long enough to see the project through.
The cooperation held for a while. Then the bickering started. Whose deflection calculations were correct. Which Redoubt should fire first. Who controlled the targeting systems. Who would pay for the energy expenditure. Who would be credited. Who would be blamed if it failed. Petty, familiar, human politics -- playing out against a backdrop of species-level extinction.
The deflection effort was not a failure. It was a partial success. The comet did not hit Earth. But the fragmented, underfunded, politically compromised network of Redoubts did not deflect it cleanly. They shoved it off course -- and into the Moon.
The Withdrawal
The Vril-ya were not a separate species. They were the inner circle: the faction within the old world's elite that ran the numbers on the deflection effort and did not like the answer. They saw the political fractures. They modeled the scenarios. In every simulation where humanity failed to sustain perfect cooperation across dozens of sovereign Redoubts for decades -- which was every simulation -- the deflection was partial at best.
While the rest of the world poured resources into the Redoubts, the Vril-ya built downward. Far beneath the deepest Redoubt, they constructed The Last Redoubt: a subterranean civilization designed to endure not just a comet impact but the cascading aftermath: tidal disruption, atmospheric contamination, surface civilization collapse, and whatever else a shattered Moon would do to a planet already on the edge. While Project Challenger built survival vaults and hoped for the best, the Vril-ya built a civilization that could operate indefinitely without the surface.
They took everything with them: the full knowledge base, the manufacturing capability, the psionic engineering, the genetic science. And then they sealed the doors. The Redoubts on the surface -- those massive deflection platforms, now repurposed as fortresses by whoever controlled them -- were left to their automated systems. The Vril-ya did not intend to return to them. They were, from the Vril-ya's perspective, disposable infrastructure: impressive hardware that had served its purpose and failed.
The Catastrophe
The comet hit the Moon.
The deflection network -- fragmented, underpowered, its targeting compromised by last-minute political interference -- succeeded only in diverting the body from a direct Earth impact. The comet struck the lunar surface with a force that fractured the Moon's crust, ejected billions of tons of material into cislunar space, and permanently altered the Moon's mass and orbit.
The immediate effects were visible from the surface: a sky that burned for weeks as debris entered Earth's atmosphere, a Moon that was visibly wrong -- scarred, asymmetric, its familiar face shattered into something no one recognized. The long-term effects were worse. Tidal patterns shifted as the Moon's altered mass and orbit rewrote the gravitational relationship that had governed Earth's oceans for billions of years. Coastlines that had been stable for the entirety of human civilization were suddenly underwater, or suddenly dry. The cometary material that entered the atmosphere introduced exotic volatiles, metallic dust, and novel compounds that interacted with the existing Substrate in ways nobody could predict -- and may explain why the present-day miasma manifests in eight distinct spectra rather than whatever the Mending and Saturation originally produced. Over geological time, these alien compounds also interacted with organic DNA in the presence of the miasma, occasionally producing organisms with encoding structures beyond the standard four base pairs: the rare and inexplicable beings the game designates as omega-pair organisms.
But the comet was not the Catastrophe. The comet was the last catastrophe: the final blow to a civilization already staggering from self-inflicted wounds. The biosphere was already destabilized by the Upvolving's escaped organisms. The atmosphere was already saturated with miasma layer. The surface wars had already fractured every political institution. The Redoubts, their deflection mission complete (and failed), turned their power systems and manufacturing capacity inward, becoming the fortresses they had never been intended to be, their owners sealing the gates and riding out the collapse behind automated defenses.
Each catastrophe alone would have been survivable. Together, they were not. The surface civilization collapsed. The Redoubts held, for a while. Their automated systems fought off waves of refugees, hostile forces, and environmental threats. Their android garrisons and cybernetic defense machines followed their last standing orders long after the humans who gave those orders were dead.
The Long Dark
The Redoubts degraded. Not quickly -- their engineering was extraordinary -- but inevitably. Power systems that were designed to last millennia eventually lasted millennia, and then failed. Defensive perimeters contracted. Manufacturing facilities broke down in ways the automated repair systems could not fix. The android garrisons persisted longest, running on degraded instructions, executing security protocols for installations that no longer served any purpose.
Outside the Redoubts, humanity fragmented. Populations that sheltered in miasma-rich zones adapted into the Eloi. Populations that retreated deep underground adapted into the Morlocks. Surface populations that survived in the open became the ancestors of the present day's baseline humanity. The Substrate continued its work on non-human life, eventually uplifting animal lineages into the Beastfolk -- though whether present-day Beastfolk descend from the Upvolving's original enhanced animals, from miasma-driven wild uplift during the Long Dark, or from organisms disgorged by malfunctioning Fallen Redoubt bio-factories is unknowable. All three probably happened. The same ambiguity applies to the Rur: some present-day Rur populations may be continuous lineages from before the Catastrophe; others may have been produced, accidentally or deliberately, by automated Redoubt systems still executing manufacturing protocols for a civilization that no longer exists. The question is unanswerable, and in practical terms, irrelevant. See The Peoples for the present-day branches of sapience.
The Long Dark lasted longer than all of recorded human history combined. By the time it ended -- if it has ended -- every trace of the old world's knowledge had been lost to every surface population. Only the Vril-ya, sealed in The Last Redoubt, retained the full record. And they had their own problems to attend to.
The Present
The surface world has rebuilt itself from scratch: feudal, barter-based, faction-governed, and profoundly ignorant of its own origins. The Redoubts still stand, incomprehensible and terrifying. The miasma still saturates everything. The creatures have adapted. The peoples have diverged. The Moon hangs in the sky, broken and scarred, and nobody wonders why -- it has always looked like that, as far as anyone knows. And far below, the Vril-ya have decided it is time to look upward again.
Beneath every road, every ruin, every foundation, the nano-colonies still hum. The ancient highways run straight through mutant forests because something in the ground keeps restoring them. Walls that should have crumbled aeons ago still stand, their molecular structure quietly repaired by machines following maps that predate every living memory. Nobody understands it. Most people do not even notice it. The world looks old -- overgrown, weathered, scarred -- but it is structurally far more intact than it has any right to be. The bones of the old world endure because the miasma will not let them die.
