It's fucking Hell!! Duh!!
But...if you need more specifics, it's Dante Alighieri's version of Hell (the book, not the retarded ass game...). Don't know what that is? Look it up. There's 9 circles for varying levels of sins. I'll post a diagram if needed. But yeah. We'll work stuff out in the forum. It's a pretty loosely thrown together RP. Nothing major.
