From first paragraph of scenario:
In “Hunters Hunted,” the penultimate story of the Manitou Springs chronicle, the characters find themselves interacting with other Uratha. Prior to this chapter, the pack has been on its own, dealing with its own problems and handling its own affairs. Now, the characters must face one of the most terrifying enemies an Uratha can confront: other werewolves. Although they have sworn the Oath of the Moon to not slay the People (i.e., other Uratha), werewolves are violent, passionate creatures, and the line between rival and foe is razor thin. In addition to rivals in the Tribes of the Moon, the characters will face one of their dark reflections: a Pure Tribe werewolf.
