I'm kinda doing a vote thing.  We may end up doing a sort of mix of things.  So far A has been more popular.

Depending on what you have in mind for demons maybe.  It's kind of an episodic collaborative fan fiction kinda thing.  Check out Chick Tracts as that was pretty much the idea for that approach.  If demons are in they're in more like Goldar from Power Rangers or as a nebulous outside force...like...jesus christ im going to say this...like The Klaw from Inspector Gadget.
