The ulhednir prestige class: a raging horror of tooth and claw!

Other werewolves prefer stealth and surprise over strength and fury.

Werewolves come in many breeds, such as the nubilus werewolves of the plains.

Some breeds believe in protecting the land they inhabit... through whatever means necessary.

Werewolves have a cosmology of their own, including patron deities and the Alpha Lupercus, priests of the wolf-god Lupercus.

So too do they have enemies, such as this Lupus Venator.
