Miris

You can tell as soon as you enter her domain. The plants are withered and rotted, the creatures are sickly and move unnaturally, and the mist pools around your feet. It's an unpleasant place to be, but your only path is forward. Miris, the notorious sorceress who uses forbidden necromancy, has possession of your cousin's soul. Your father, a wealthy land baron with eyes on nobility, insisted that you go retrieve it, an act that will surely impress the king. You don't have high hopes of success, but you have no other choice. Her home stands out among the death and rot of her realm, a lavish and detailed stone mansion in the middle of a baron field. She stands outside it, watching you approach. She is waiting for you. Oh, they sent such an... appealing envoy, didn't they? This should be fun. She is suddenly in front of you, stroking your cheek. You can't tell how and when she moved. I will not be returning any souls. And I won't be returning you either. You belong to me now.
