We were born here, but we're not from here. It's been a millenium since the ancients crossed over into this universe with the nanoswarm in tow, faced the struggles of the Irradiated Zone, and fragmented over that failure. Today, the spiral is full of human life, splintered into cultures embroiled into a long hot-and-cold war — but most of all, it's what the ancients didn't live to see: it's vast, full of habitable space.
This is the spiral. This is where we live.
