It is the near future. The Collapse is over. Years of accelerating decay culminated in a brief and vicious global war. When it came, the final conflict seemed almost an afterthought in the wake of disease, famine, natural disasters, and economic and political failures on a previously unimaginable scale. None of these calamities could have ended the world by itself. Together, they brought the engines of civilization to a grinding, blood-soaked halt. Now, as the apocalyptic Last Year draws to a close, scattered survivors band together against the darkness. You are one of the ten percent of humanity to make it this far. Some would call you fortunate. You're not so certain.
