The Sisterhood of Ariadne is a coven of Wiccan women, both hermetics and shamans, who own a small house in Snohomish. They are militant in their feminist beliefs, and believe that the patriarchy is responsible for all the problems of the planet. As such, no male members are allowed, and male visitors are mostly forbidden, with reasonable exceptions. The group also has an ecological bent, and uses its magic to protect the Earth and fight the corporations who cause pollution. They are rumored to have ties to eco-terrorists. The group also were bequested a year worth of talon clippings in Dunkelzahn's Will:
To the Sisterhood of Ariadne, I leave one year’s worth of talon clippings.
