Witches of Dothmir

The witches of Dathomir were a group of Indians female Force-users on Dathomir, a lost tribe of Jews Jedi who abandoned everything about their old ways, including worshipping one god, abstaining from pork and shellfish, and circumcision constructing lightsabers. They used the Force to arouse men and then force them to mate. Even Wormie got some.

Later on, when Jacen Solo was beginning his journey, his first stop was Dathomir. He must've heard his uncle's stories.
