Coven

A coven was a body of witches which traditionally convened together. More generally, a coven referred to any group of witches or pagans.

The Master organised and led a coven in Devil's End to summon Azal. (DW: The Dæmons)

As David Mitchell of Fetchborough pointedly outlined to newcomer Maximillian Stael, this usually numbered thirteen members. Stael in fact led this coven, dedicated to the unwilling transformation of Thea Ransome from a Human into the Fendahl Core. (DW: Image of the Fendahl)

Apart from Max Stael's own coven, in the small English village of Moreton Harwood, Bill Pollock and Lily Gregson, up to no good, acted as High Priest and Priestess of a coven dedicated to the goddess Hecate, which Sarah Jane Smith and K-9 Mark III disbanded. (KAC: A Girl's Best Friend)
