It's officially 2197. After 149 years of conflict between Angels and Demons, the world was destroyed. There was nothing left besides a bare, frozen piece of land scattered with blown up trees and overturned hunks of metal. Almost every human has been killed and a Demon is trailing behind someone who seems to be the sole survivor of the species - rather clumsily, I might add - towards the Angels Palace at the other end of the burnt city of London. I mean, who needs a guardian Angel when you have a Demon protecting you?
