It IS possible to save Duke Ravengard after you cut Wyll's contract but it's significantly harder and Mizora will interfere. Just found this info
on Reddit.Yes, I know. I've done that four times now. Mizora can go to... well, y'know.
This is how Wyll's storyline works out in my games:
Wyll: Hi! I sold my soul to a devil because it was Heroic.
Me: What?! That was a terrible idea!
Wyll: No, no. It's cool. I'm fine with it. Anyway, Mizora is pretty awful, isn't she?
Me: ....
Wyll: An evil, lying, backstabbing, sneaking, manipulative piece of (&**.
Me: ....
Wyll: Oh, and she has a new contract for me, think I should sign it?
Me: .... NO, OF COURSE NOT.
Addendum: Balduran was evil. The end.
