EABA Age of Ruin
DEMO
In the late 21st century¸ practical nanotech became a reality. Then it mutated and got loose. Or it was stolen and used as a weapon. No one is really sure¸ since by the time it was brought under control virtually all of Earth's infrastructure had been destroyed.
That was five generations ago. Humanity still survives¸ the crippled biosphere supported by protective nanotech that shields it from the pervasive presence of the "eaters". With advanced tech impossible to keep protected and operational¸ people have turned inward¸ Shaping themselves with nanotech to become the tools they can no longer manufacture.
Meanwhile¸ the eaters have also evolved¸ clustering together into vast consuming intelligences. Can the Age of Ruin be turned into the Age of Redemption¸ or will the fifth generation after the Fall of Man be his last?
