17 Functions akin to a nocturnal creature. By day he is sleepy, morose, and disinterested, seeming to barely be functioning (not the best for adventuring), but by the time the PCs settle down for an evening's campfire, he animates and becomes hyper-active, suddenly following up on conversations he had completely ignored earlier, swinging his axe around shouting out challenges to unseen foes in the darkness, and if all else fails, begins singing at the top of his lungs. He will try to keep everyone up as long as possible, and generally annoy his sleepy comrades. At least there is never an issue with him around, as to who will stay up to guard every night. When morning comes he reverts back to walking-coma mode, indeed, the PCs spend up to an hour each day just trying to rouse him.
