If it's at all possible for either of you, OP, and the other AC, try this: Keep them at arms' length yet at the same time press them for information whenever you can. Beware though, if they're caught your source or sources will be tortured at an undisclosed location till dead. I find it mighty unlikely that in their ever Corrupted state of mind, body, and soul, they'll fight to keep you safe. More than likely as soon as they tell their Master(s) the truth your former source will be executed on the spot and or made an example of while they seek YOU out. They own this Human World lock, stock, and barrel. If they really want to get to you, they'll get to you regardless. It doesn't even have to be physically... they can get to you from on the Astral Plane as well. Good luck.
