Well, while it is true that Deacon has helped mages escape from the Circle, He still would not work with a mage that would intentionally practice blood magic. He helps mages because he has seen plenty of mages resort to blood magic to defend themselves from Templar knights, and he knows that by helping them avoid confrontation with the Order, he can prevent another such tragedy. He knows these people, why they left. He knows that should they be returned, they would either be unjustly made tranquil, or even killed in order to silence them.
Still, I should be able to work with this, but I need to ask something to you in a PM before I post.
