Very good, very moody. Liked your descriptions and setting. Only problem (which you, yourself pointed out) is, unless you move it to someplace other than hell (or any permutation thereof), it's really of limited utility.
Which is a darn shame.
I was thinking that a game like Deadlands (with the demons properly toned down of course) could really make use of this.
