A good piece of background detail, though it really does not live up to the billing of being more interesting then what we could create. In some ways, it could be the history of a rock band with the changing of the membership, splintering, and the like.
A culture has a tradition of wearing animal pelts as a sign of status or job. Carpenters might wear beaver skins, Masons have a moleskin hood to their cloak, Gaurdsmen might have badger pelts. Done to show the culture's respect for nature and how much of nature is equal to each other.
