Werewolves are humanoid hybrid creatures that inhabit the Nameless World. They were created by the Faerie as a terror weapon in the Faerie War, and are capable of using magic themselves. They travel in packs, and resemble some form of culture and society. They are barred from entering human settlements.
Unlike werewolves in our world, werewolves in the Schooled in Magic canon are not men who become wolves, but wolves who become men. However, like werewolves in our world, those who are bitten by werewolves become one themselves. Likewise, werewolves are unable to regenerate from wounds if they are inflicted by a silver blade.
