Hmm... the only issue I see is I'm not sure how he would get out into the forests outside of Karstberg by himself, given that the city is walled to keep it protected from outside dangers. Not that going out there means death or anything, but there's guards posted and it can be dangerous given there can be things like T-rexes hanging around out there. But hm.

Also I'll need to talk to Rin but yeah. ^^;
