Ulfric is the king or leader of a werewolf pack. He is considered the ultimate alpha male of the pack. The Ulfric will be replaced by whoever defeats him in combat. In theory it does not have to be a death fight, and the Ulfric can in fact step down, but the new Ulfric will usually kill the old one to prevent a dominance split, as Jacob intended in Narcissus in Chains. Theoretically, female weres may become Ulfric, but female Ulfrics are rare because the strongest males normally have a significant strength advantage over even the strongest females. The term is a derivative of the Norse "ulfr," meaning "wolf."
