Earth that was.. In the year 2290 earth went to war with itself. Neutron bombs rained like fire from the sky. Neutron bombs only destroy living material. Cities went from populations of millions to empty in one barage of bombs. When the first wave of bombs started, people started heading for the cryotubes. Those that made it do not know how much time passed.
Currently the year is unknown, who keeps records of such things when your fleeing death. The world as you know it is gone.
