In regards to Wyll's patron (the lovely lady to has wrapped herself about him) is she a succubus or an Erinyes? And if she is a succubus is he a devil or a demon, because apparently Succubus can be both. Though given the prominence the Nine Hells are playing, I am going to go for a Devilish Succubus. Raphael sure has some competition.
That is also a very interesting staff that Shadowheart is wielding.
