The Backflip Boy used to play In Nomine with a bunch of our insane Ren Faire friends up in Milwaukee, actually--it's based pretty much half on Dante and half on Terry Ptarchett and Neil Gaiman's _Good Omens" with some of the Prophecy films thrown in for good measure.

As for art, Carol Burell, an old friend from RoS fandom was an art designer on one of the In Nominee books, so hey, you never know... :)
