Once, every ten years, the Werewolf pack, the Witch Coven, the Vampire coven, and the Faerie colony come together and hold a ceremony. This rare ceremony determines whether the hybrids within their ranks are worth it to keep in their group, so they leave the selected half-bloods alone and chained up in the wilderness, and if they are worthy they will escape their bindings and find their way home. If not, after three days a werewolf beta will be sent to kill the victim.
