You know Anselm Teel from a ways back. Maybe from a long ways back. Could be you got into trouble with some powers you didn't understand. Could be you got into trouble with powers you completely understood, but you just didn't think were paying attention.
Or maybe it happened longer ago than that, when you were a kid and just needed someone to be kind to you. As far as you remember, he was good at being kind.
However it happened, whenever it happened, you owe Anselm Teel a favor, and he is calling it in.
