I want to make one thing clear: the character doing this is an evil jerk. This is fantasy, pure and simple. Still, sacrificing the soul of a peasant who should be in your protection is evil. That being said, kink is kink. I almost want to do a third page as a "freebie" where the guy who did this gets some karmic retribution. We'll see.
As an aside, the textures for the wings are modified and not available with the original assets, though I will happily explain how to do the modifications.
