Dunaik is a dwarf slightly below average height, but seemingly above average weight with most of it appearing to be muscle. He is completely bald, has a white beard, and his skin has a somewhat unhealthy greyish tint to it.
He tends to be a bit reserved, but when he does engage in social interactions he appears to be a bit "off",  as though he doesn't fully understand all the unwritten social rules. Similarly he has a clear (but somewhat undefinable) accent to his common speech.
