[Suzerain of Sheol]

Oh, well, I mean that it would be a lot of work to develop the setting since I wouldn't be able to use any of the standard DnD stuff (well, little of it, anyway).

But my basic idea at the moment is a post-apocalyptic setting based on the Book of Revelation where humanity is struggling to survive the apocalypse while the dead walk, false prophets take over nations, angels rain ruin on the earth, sorcery springs up among humanity, demons crawl forth from the abyss, the Four Horsemen ride the world sowing chaos in their wake, you get the idea.
