I still have problems with that seer/sage part. Suppose he finds out the assassin, now he makes a public post that "Yes, X is the murderer, I saw him cleaning the blood stained blade" or something like that? Or he does it in some *secret* way?
Well it is much smarter to do it secretly because if you say you are the seer/sage the werewolves/assassins will try to get you killed.
