Everything going on in Kazdel so far is being machinated by the Confessarius. And also the very person who wanted to resurrect Theresa. In fact, this might be the exact reason why Theresa had the Doctor murder(?) her in the first place - to pass on her powers to Amiya, so that the power of the Lord of Fiends is firmly taken away from the grips of the Confessarius. What a control freak.
