Alright, so he says drinking won't kill him, at least not yet. On one of my playthus, I find his dead body on the stairs of the inn. My guess is alcoholism, altho it might have been a vamp, cuz on the next day, a vamp and 2 death hounds attack, and vamp raises his corpse.
I just ran into the same issue. Walked in The Frozen Hearth and no body outside, come right back out and there he is dead on the top of the stairs. The guards came up to the body but their only responce was "Oh what happened?" ant then walked off lol
