Lost Epoch

2012 Earth frozen over.

Life
On Lost Epoch there is life, but only far under the sea, around volcanic vents. There, many types of tubeworms, crustaceans, and microbes thrive.

It is thought that there is a single lifeform above the ice. Nicknamed Giant Enemy Crab, it's a mutated form of a typical volcanic-vent-dwelling crab that's car-sized.

It, however, starved to death. Yet it's preserved by the insane cold.
