Worriz is the head of the Wolf Tribe. Despite this, he doesn't hold much more power than the other members because the tribe works together as a pack.
Wolves are pack animals who live in such close quarters that they share a kind of hive mind. Group decisions are usually arrived at easily and unanimously, so there is no real need for leaders. However, the wolves’ transitory nature and traveling battle caravans often bring them into contact (and conflict) with other creatures, so someone in the tribe has to handle negotiations with “the others” (as all nonwolves are known). Worriz was given this role because he was considered “the most personable.” In reality, he is a vicious, ruthless backstabber. His only saving grace is that he is able to disguise his true nature long enough to fool the other creatures.
