The short and terrible reign of the Antediluvians leaves the world in ruins. Fewer than one in 100 humans survived the end of civilization and the battles of the undead. Starvation, plague and cold killed most of them. Of a population that exceeded six billion, now less than fifteen million remain, scattered about the world.

YOU MANIACS! YOU BLEW IT UP! AH, DAMN YOU! GOD DAMN YOU ALL TO HELL!
They said it was the end of the world, and they were mostly right. The planet is still here, and even some of the people, but nothing is like it used to be. The cities still stand, but their occupants are all dead standing, walking dead. Maybe there are fewer than there used to be, but then again, there are also a lot fewer of us.

When all is said and done, the world writhes in the throes of Descent, damnation seemingly everlasting. Magic still lives, though the numbers of its practitioners are much diminished, save for the Fallen. Demons, dark spirits and Unspeakable Horrors from Beyond walk the Earth with impunity, and some lord over scattered enclaves of miserable survivors as dread taskmasters and cruel barons. The Fallen revel in what they have wrought and settle in to enjoy an eternity of ruling over a helpless human race largely reduced to Iron Age civilization and subject to depredations unknown since the worst excess of the priests of the demon-gods of the ancient world.
