Earth: 2700 AD

The surface of the earth is a volatile place. The impact disrupted the planet's surface structure, and volcanos have been erupting routinely for the last century. The planet is becoming increasingly hot, vast tracks of land are contaminated with nuclear fallout. Most, if not all of the cities of the past civilization have been abandoned; small pockets of multi-species people are separated by rapidly expanding wilderness. Ocean levels have risen considerably, and the surface of the Earth is nearly unrecognizable from a distance.

There is also the problem of numerous experiments that may have gone out of control because of the sudden collapse of society. The of the various species created by the civilization, most have died out, leaving the hardiest of science's creations to maintain a grapplehold on the earth, which will be a likely target for invasion by anything.
