Kjell would be considered to be a ancient Goliath, who have long been past his prime.
His most prominent feature would be his burn scars that covers parts of his left side, stretching from the side of his head downwards along his neck. The scar tissue itself has been ritualistically tattooed with a design of a leaping wolf, who's open maw opens over his cataract left eye.
His body is sinewy and thin, covered in furs and blankets, and seem to have been bound to a intricately built wheelchair for some time.
