The Moonrise Coven is a tightly-knit group of practicing pagans, many of whom are werewolves. They take the time to get to know and initiate their prospective members, and so while not all members are werewolves or even supernatural in nature, it's known within the coven's whispers which of its members have the affliction.
The Moonrise Coven takes issue with the idea of using magic for harm, due to its unpredictability and ease of weaponization. Left unchecked, it could become a tool of the educated upper class to keep unprotected groups down. The Moonrise Coven doesn't believe in fighting fire with fire, they believe in fighting fire with tooth, claw, and gun, should it ever come to that.
