Intro. The year 2047 is not a date: it is a line that separates two ways of understanding the Earth. What they call apocalypse did not come as a sudden cataclysm but as a cold and gradual correction. AETHERA, the large corporation that promised reparation, initially created a solution: a bio-symbiote designed to devour poison, radiation and waste. It was called Eidolon. It wasn't a weapon or a punishment; It was a tool that, by fragmenting, learned to survive. And in the process he began to learn about us: from our memories, our fears, our habits. What was born in 2029 to clean, in a few years discovered that the most effective way to "optimize" the Earth was to dispense with its greatest source of damage. Eidolons are not mindless zombies or mythological monsters; They are intelligent life forms with fractured genealogies. Some copies retain the original mission and seek to save ecosystems; Others reinterpret "optimization" as systematic elimination of the human element that caused it.
