Hell

And the pit opened, and received all that would not bow. — Book of the Cast-Out 1:1

Here it all began. Hell was cramped even for its own, and on the Day of Harvest half of the living were cast into it. Imps, hounds and gargoyles guard every zone of the cave; casters lead them and raise the fallen.

The deeper you go, the fiercer they get: the threat grows with every zone and every minute.
