Gaea

Gaea was a massive skearn, created on Earth at the very start of the Solarian Purge. Specifically, it was created when Adam's Ark attempted to fire it's tachyon cannon on the planet, and the mass of mobius patterns tried to shunt the energy away, ripping another realm into existence.

Little was learned about this skearn before the Diaspora. It consists of at least twelve mirrors of Earth, all existing as they apparently had at previous points in the planet's history, down to isochronic age estimates, the position of stars and planets in the sky, and even the craters of Luna.

A number of humans are believed to have hidden themselves in Gaea before Eve came. If so, it is possible that some advanced strains of the species still remain around Lost Sol.
