The origin of werecreatures is currently uncertain. At least one pack of werewolves' origin is described in their tribe's legends of Spirit Warriors, as one day a man left his body in spirit and was forced to share the body of a wolf nearby after his own body was stolen by another spirit. Then he was able to transform back into human through the wolf. His children and descendants were afterwards able to shape-shift into werewolves too, and would do so whenever danger threatened them, their families or the tribe. However it is not known if this myth is true or not, and whether other werecreatures were originally people who left their bodies in spirit form and shared the body with an animal. Some other tribes share similar legends, while others have none.
