The Dark Coven, or simply the Coven, is a cult of dark mystics under the service of the seven Great Evils. It is a remnant of the Triune, the ancient religion that revered the three Prime Evils as gods. Cultists summon demons up from the Burning Hells to help them fight the forces of good, greatly outnumbering the opposing force. The Coven is led by the evil witch Maghda, who answers to Belial, the Lord of Lies.
The Dark Coven is made up of Dark Cultists, who use evil magic to torture their enemies and summon demons from the Burning Hells to serve them. Demons used by the Coven include the houndlike Hellions, the twisted Fallen, the hulking Dark Berserkers, and the Dark Thralls, demons that possess ritually-prepared human hosts called Dark Vessels. Summonings usually require three or more participants depending on the type and number of the demons being summoned. Sometimes a ritual can be disrupted by killing a few of the circle, but other times, the entire circle must be laid to waste to stop a summoning. The Coven also employs a number of necromancers who create undead beings, such as Jondar.
