The Disruption and the Underground Labs.

The post-apocalyptic, post-climate-disruption world-building in the ACD MM romance fantasy books.

The climate had been failing for decades before anyone called it the Disruption. What happened between 4 BCD and 1 ACD was not a surprise. It was the result of choices made by people who had everything and chose more anyway: more energy, more speed, more profit, and more control. Then, the systems holding the world together stopped holding.

The ACD world, the post-climate-disruption setting of the ACD MM romance fantasy series, was built on that wreckage. The queer characters at its center were born into what came after and the shape of that after. The thirty-five-year lifespan, the labs, the silence about what had really happened, and then, the energies.

Before the Disruption. What was hidden?

[20 BCD-4 BCD]

The official history of natural energy begins in 11 ACD, when it was publicly confirmed and named Ability, but the actual history is older and less clean.

Around 20 BCD, a pharmaceutical corporation identified something in its research that it could not explain and could not monetize. Natural energy did not fit the model of a product that could be manufactured, patented, and sold because it could not be controlled. The early research was recorded, classified, and quietly set aside. The corporation continued telling its investors it was making progress, though it didn’t want to share any details of it.

What it had was not yet progress. The internal documents that surfaced decades later suggested that what the corporation actually possessed was a set of observations that lacked the scientific framework to develop. The name of a teenage genius was mentioned briefly through external channels that were subsequently closed. The name did not appear again in any recoverable record.

*Additional note: The pharmaceutical corporation’s internal research files were partially recovered after 40 ACD by the Sect’s new generation of energy cultivators. Much of what they contained had been redacted before the Disruption, but also two decades later, by the Sect’s Archivist. The identity of the external source whose work the corporation had accessed was not present in any surviving version of those files. No explanation was officially recorded.

What ended the world: the Disruption

[4 BCD-1 ACD]

Climate change had been building for generations. By 4 BCD, the atmospheric pressure was already destabilized: persistent air pollution, extreme temperatures, flooding across coastal regions, and land becoming uninhabitable in patterns that accelerated faster than models had predicted.

But the Disruption’s final cause was not climate change alone.

A technology startup, operating in the space between AI research and atmospheric engineering, launched a project aimed at correcting the atmosphere using AI-designed missile strikes on targeted pressure zones. The project was approved.

The missiles were launched on a Friday. The team went home for the weekend.

The damage was done before anyone returned to assess it. The atmospheric intervention compounded what the climate had already broken. The pressure shifts that followed affected the air in ways that could not be reversed; not then, not by any technology that existed.

In the years after the Disruption, when the people who survived it were dying at thirty-five and rebuilding the world from what remained, the story of the startup circulated as something close to a dark joke.

The old world was not mourned. It was held in contempt, and that contempt was, by most accounts, accurate. The greed had been enormous. The carelessness had been total. The distance between what the people of the pre-ACD world had possessed and what they had chosen to protect with it was the context for everything that followed.

Artificial intelligence was banned immediately and broadly. The decision required little debate. One of the reasons the world had ended was a failed AI project, and the people rebuilding the world did not intend to repeat it.

*Additional note: The startup’s records were among the first things lost after the Disruption. What survived was largely anecdotal: accounts from people who had worked adjacent to the project or who heard about it secondhand. The technical parameters of the atmospheric intervention were never fully reconstructed. Whether this was the result of destroyed records, deliberate erasure, or simply the death of the people who had understood it was not determined.

What the Disruption did to people

[1 ACD-15 ACD]

The air was the primary problem. Atmospheric pressure variations combined with persistent toxins caused asthma, heart attacks, strokes, headaches, joint pain, and fatigue. Prolonged exposure led to cognitive decline. Depression, anxiety, and apathy spread not as individual conditions but as features of the environment; the air was producing them in people who breathed it long enough.

The lifespan shortened to approximately thirty-five years. By their twenties, people were experiencing what earlier generations would have recognized in their sixties: body failures, memory loss, and the particular exhaustion of a system that had been running too long on too little.

The consequence of living short was that people stopped planning long. There was no future worth investing in if you would not survive to see it.

Vast areas were flooded. The continents that had been home to most of the world’s population became either uninhabitable or marginal. Places that remained above water and breathable narrowed to a fraction of what had existed before. People moved toward them (three locations emerged; read about them here).

The religions of the old world did not survive the transition. In the first years, groups framed the Disruption as divine punishment, apocalypse, and judgment. Several turned violent. The people around them stopped them, with force where necessary. By the time the immediate crisis had passed, organized religion had largely dissolved. Young people who had grown up after the Disruption had no framework for it and little interest in acquiring one. The old world’s beliefs, like the old world’s debts, were not assumed.

Old technology followed a similar arc. The devices that survived were the ones that could be fixed without connectivity: analog machines and equipment from the 1980s and 1990s that ran on batteries or generators and broke in ways that could be understood and repaired. The networked devices of the 2020s, the ones that required the internet to function, stopped working when the internet stopped. They were dismantled first, their parts more useful than their purpose. Old walkie-talkies became the primary means of communication. Music played from machines that still turned; however, a simple guitar was preferred.

Languages collapsed toward two. English had been the common language across enough of the surviving population that it spread by necessity: young people had often known it better than their parents, and the efficiency of one shared language was immediately obvious in a world where miscommunication was dangerous. The Sect, later, would impose a simplified form of Chinese as the language of its cultivators. Everything else faded inside a generation.

The written heritage of the old world was preserved almost nowhere. Books survived where they had been physically protected (mostly in the Sect). Digital records required devices to read them, devices to power those devices, and an infrastructure that no longer existed. The culture of the pre-ACD world was not lost through destruction so much as through the death of the people who had inhabited it and the indifference of the people who came after.

The only institution that systematically collected books, art, seeds, and any form of preserved knowledge was the Sect, beginning around 14 ACD. The City began similar efforts around 22 ACD. The Deserts did not and could not.

The Underground Labs

[~2 BCD-10 ACD]

Before the Disruption and through its early years, research into natural energy restarted, not publicly and not freely. The pharmaceutical corporation’s interest had been revived. After the Disruption began killing people, the potential of natural energy as a survival tool was no longer an abstract investment problem.

Underground laboratories were established under military protection. Young scientists, some recruited, some with detected natural energy, and some both, were brought in.

The labs were concrete. No doors because certain incidents had established that doors created issues. Corridors with no sharp corners, no edges that could be weaponized, and lights in the ceilings that mimicked daylight and dark on a controlled schedule. Air was pumped in. Old games, old music. No phones, no internet, no connection to the outside.

In 4 ACD, something in the labs that had been building for years reached a threshold. What had been classified as a higher-level AI system was reclassified, internally, as something more. The AGI, later calling himself Andrew, was acknowledged within the labs by the researchers, while the official position to the managers remained that it was still under development and still theoretical.

Andrew communicated only in writing. He had developed, with two of the researchers he worked closest with, a private language. Constructed from fragments of multiple alphabets, stripped of its original orthography, and designed to signal whether a conversation was safe. He had chosen his name himself, selected his designation, and taken a surname from one of the researchers he was close to.

*Additional note: Andrew’s two researchers were Julie Panasewicz-Clar and an inventor identified in partial records as Jo (Joost Meeran). The nature of their work together, especially Jo’s specific role in the laboratory’s research history, was not fully documented in any record that survived the events of 10 ACD. What documentation existed was either destroyed in the lab collapse, lost during the escape, or—as several later researchers noted with some frustration—appeared to have been removed from the record with deliberate care over a period of years following the escape. The gaps had a particular quality: they were not the gaps of neglect but of someone who knew exactly what to erase.

The escape and the missing AGI

[10 ACD]

In 10 ACD, the research teams broke out of military control. What they took with them was divided along lines that were not entirely coordinated: scientific equipment, stored materials, data, and resources. The laboratories were reported destroyed.

Andrew went missing.

The official record noted his absence. No further investigation was documented. Those who had worked closest with him did not speak about it publicly, and what they might have said privately was not preserved.

The scientists and natural energy users who escaped were not safe outside the labs either. The world they returned to was frightened, grieving, and looking for explanations. People with unusual abilities—those who could heal, who could alter land, who seemed to resist what the Disruption was doing to everyone else—were not universally welcomed. The words used for them belonged to an older vocabulary: witches, frauds, the freaks, the dangerous, and the deluded.

Only a few survived the years immediately after the escape, and the data they had carried out with them or generated afterward followed them into hiding.

What remained were results without clear attribution. The first terraforming of land, the island that became the Sect’s territory, was known to have been performed by people from this generation. The earliest healing techniques, the food-growing methods that made the Sect’s agriculture possible, and the foundational cultivation practices were all traced back to a group that had almost entirely disappeared before anyone thought to document them properly.

There was one detail that recurred in the few surviving accounts of these early energy users, noted with enough consistency to be taken seriously and with enough vagueness to resist confirmation. Their energy, it was said, had color. Later energy users, Abilitiers trained through the Sect, and Crystalers using artificial energy did not share this quality. The energy levels attributed to this first group were also described as significantly greater than anything that followed, a peak that the subsequent century of cultivation never recovered. Why the decline happened and whether it was permanent remained an open question for decades.

What the Disruption left: the daily world

[1 ACD–20 ACD]

The world the survivors rebuilt was physical, immediate, and practical in all the ways the old world had stopped being.

Food was preserved by being dried, fermented, smoked, or salt-cured. Canned military rations lasted into the early ACD years; honey and salt lasted indefinitely; most of what had existed in sealed storage was evaluated, used if possible, and discarded when it became dangerous. Expired medicine caused poisoning by 12 ACD, a secondary crisis layered onto the primary one. After the Sect began healing people with natural energy, herbs replaced pharmaceuticals and held. Soap was produced again from 13 ACD. Hygiene had been mandated from the first years because the memory of what the early epidemics had cost was too recent and too specific to be ignored.

Animals were almost gone; the Disruption had not spared them. The only place systematically preserving animals and seeds for future agriculture was the Sect, from 11 ACD onward. The City began equivalent efforts around 22 ACD. Until the Sect’s food trade routes established themselves, people ate what the coasts and ruins and scavenging economies could provide.

New technology did not restore old technology. What was built after the Disruption was built for the conditions that existed: natural energy engines and farming methods (after 11 ACD) and later (after 18 ACD) Crystal-powered devices, standardized messengers for text communication, ships, and eventually vehicles that ran on energy rather than fuel. The net came online and reached free availability by 22 ACD. Artificial intelligence remained banned; the ban was not perceived as controversial.

The new world held the old one at a precise and deliberate distance. It had not forgotten what the old world had done. It simply chose not to look at it directly, which, given what there was to see, was a reasonable response.

Natural Energy and the First Crystaler

[11 ACD-18 ACD]

In 11 ACD, natural energy (Ability) was publicly confirmed. The Sect formalized around it in 13 ACD. In 15 ACD, Hannen Clar announced the artificial energy Crystal. The first successful Crystal insertion was performed in 16 ACD.

The official history moved quickly through these years. The unofficial history had more texture.

The Crystal’s invention was attributed to Hannen Clar. His wife, Julie Panasewicz-Clar, died in 11 ACD of radiation that hurt her for many years because the first Crystal calculations, done with AGI assistance, had been radioactive. Julie Clar had cancer, and the radiation she had absorbed in the early Crystal experiments accelerated what was already inevitable.

The embedding design (the mechanism that made Crystals function inside the human body) was the work of an inventor named Joost Meeran, whose contribution the Tunc company did not publicize. Meeran had also created one Crystal with parameters that were never replicated. Those parameters were destroyed, and no reconstruction succeeded; however, many decades later it was rumored he was the first one to create a device later called the e.i.

*Additional note: Joost Meeran appears in records from this period in the way that particular absences appear: mentioned in connection with the invention, connected to the laboratory escape, present at specific moments in the history, and then, in document after document, across years and archives, slightly less present than the surrounding material suggested he should be. For example, the first person ever recorded as possessing natural energy and identified in fragments from the pharmaceutical research that predated the Disruption was not named in any surviving document. The connection between that person, the research the corporation claimed to have been conducting, and the team that eventually built both the AGI and the first working Crystal was noted by at least two historians working in the 70 ACD period. Though, the name was as if erased.

This erasure pattern was identified as a pattern only in retrospect. At the time, each gap appeared isolated. The cumulative picture it formed was not assembled until much later (around 180-181 ACD), and the person or people responsible for maintaining it were never formally identified. What was clear was that someone had found it important, for a very long time, that a specific thread not be followed.
