Demons & Shadows
Atty appears to be crazy, but he knows more than he says, or he says more than he knows. At some point he will be killed, either because it is revealed he is evil, or because he is good. It does not seem possible he will remain a living innocent.
All kinds of wild crap spews from his mouth. Scrambled but I bet it makes sense if you are in the right (or in the wrong) frame of mind. “friend to foe, foe to friend…. Beware shadow of the trees” something like that. Perhaps he was driven insase from intense magical studies beyond his ability.
