Well, there are multiple kobold tribes in the region, so it's not strange for there to be one. Leaving the tribe and being able to speak Taldane are plausible, as well. You'd have to consult Autocad about how a kobold would be recieved at Restov or at least at Oleg's place should Restov happen to be unwelcoming.<br/><br/>As for cleric and druid classes, the thing to watch out for is that they're trained, so you'd need to account for the source of said training in your background. Cleric might not be a problem if it's a deity that could be plausibly worshipped by kobolds, not sure about druids.
