Darkhaven

Darkhaven was the birthplace of General Woundwort. Originally it was a happy, cheerful warren, until humans burned the rabbits out and killed Darkhaven's Chief Rabbit, Hemlock - Woundwort's father. The survivors eventually returned and started a new warren, only with a twisted, pseudo-religious idealogy that "the Dark One" (Woundwort) would return and lead them to glory. As a result of lifetimes of combat in the battle pit (and possibly due to industrial byproducts from a nearby factory), the Darkhaven rabbits are all scarred and deformed, and utterly merciless killers.
