Cultists of Hecate

Hecate is an old tribal Goddess of evil magic, night and mystery. Many of her devotees believe that Dragons still stalk the lands of Yore, though none has been seen alive for millennia, and that Hecate had a pivotal role in overcoming the Great Darkness in the eighth century, although they offer little proof.
Some say the fey witch of the Margreve, Baba Yaga, is the living avatar of the Lady Night in Yore; others say she is just a savage old crone who steals babies and sells them to the spirits of the forest.
