The earth has been hit by a nanite apocalypse, that the governments of the worlddubbed the Promethean Nanites before they themselves broke down.

The nanites, also referred to as the Promethean Plague, the Nanite Plague, and the Scourge, are virus-based artificial swarming strains of proteins and enzymes controlled by micro transponders. Initially designed for use as a curative system in the medical field. They should have been capable of healing any ill or repairing any injury. Instead, they turned out to be capable of instantaneous rewriting of a victim's physical appearance and DNA, doing things as 'simple' as blending one physical structure (say, that of a mouse) with another (human, maybe) that results in a viable life form, to something as complex as dragons or other fantastical species known as cryptids.

They should have been a boon to mankind. Instead, disaster was the result.

The nanites are ever-expanding, producing more of their numbers as they infect more and more victims.

St. Louis was once a thriving industrial city, but now stands as a maze of reclaimed ruins and dense forests. The Promethean Nanites have reshaped its inhabitants into diverse anthros and cryptids, leading to territorial disputes and unique alliances. The iconic Gateway Arch now serves as a strategic stronghold for the city's independents, who repurpose its steel structure for fortifications. Underground labs, run by cabal agents, work to their own unknowable goals, while bioweapons patrol the outskirts. Amidst the chaos, scientists covertly gather data to understand the nanite spread and its unpredictable patterns before the apocalypse reaches a point of no return.

You're one the survivors, victims, or perpetrators of the nanite virus... now it's up to you to survive, avoid infection and potentially becoming a feralmind as you try an make a safehaven for the unmutated and sane mutants. Study the virus as a scientist while avoiding infection, or manipulate the virus to create the furture you desire as a cabalist.

This particular bot is based on an adventure I made for myself on AIdungeon, which itself was based on the text game Flexible Survival. This one I have based in St. Louis during a transformative Nanite Apocalypse.
