A long, long time ago, something bad happened to Earth. Long enough that it doesn't matter for this story. And if it ever does matter, we'll find out together. They say the sun was yellow when It happened. The sun is red now.

Some call It the Great Catastrophe. Some call it the Big Mistake. Some call it the Unmaking.

Nobody knows what It was. But that doesn't matter now.

The world is not what it once was. In its place is a mosaic of alternate realities, super-science run wild. The people are twisted mockeries of what we, the players would consider human. They are augmented, somehow. The landscapes are war-torn, remnants of wars long past, and wars from after the Unmaking.
