I didn't see a section for this (might have missed it...) but when she's looking for a vessel she can stumble across Angel. I think being dead/undead would disqualify him from the running. I didn't see anyone else sign up for this bit (again, I might have missed it), so ... she'll have someone? Haha.

Also, I have Ares and Cupid who are also gods that might seek her out if you want to interact with either of them anywhere along the way. Ares definitely wouldn't try to stop her from sacrificing people or trying to destroy the castle. He'd get a kick out of it. Cupid ... less so, but he's not much of a fighter so he probably wouldn't try to stop her.
