Mankind took the mark, after a profound credit crash. The world is plunged into a global depression. The rapture took those Believers to be with Him. Many others were left behind. Then, the demons came, as an all out assault on God's creation begins.
Some seek to redeem themselves. Some have developed powers--known as Supernals. As the world teeters on darkness, those with great power have a role to play.
Salem City, a large fictional northern Midwestern sprawl. Taken over by the Human Liberation Front, of the United Nations, it has become a place of sin, vice, and poverty.
And it is now becoming inhabited by supernatural forces opposed to God. The perfect battleground for a supernal to redeem him/herself. Block by bloody block.
