The Black Coven was an occult secret society led by Doctor Felix Kriegslieter which allied itself with Adolf Hitler through Heinrich Himmler, who allowed them the use of Drachensberg as their base. In actuality, the coven was a front for the War Lords, who used advanced technology disguised as black magic as part of their plan to ensure Nazi Germany would win World War II. The Seventh Doctor uncovered their schemes, resulting in their deaths at the hands of Hermann Goering and his men. (PROSE: Timewyrm: Exodus)
