Yazidism is an ancient religion linked to Zoroastrianism and Sufism. The religion is seen as a highly syncretic complex of local Kurdish beliefs that contains Zoroastrian elements and Islamic Sufi doctrine introduced by Sheikh Adi ibn Musafir in the 12th century. The Yazidi believe in God as creator of the world, which he placed under the care of seven holy beings or angels, the chief of whom is Melek Taus, the Peacock Angel.
The Yazidi religion is properly a distinct religion but is treated as a Sunni heresy in the game. Yazidis believe that God created the world and left seven angels in charge, the chief of whom is the Peacock Angel, Melek Taus or Shaytan, a being usually identified by Christians and Muslims as Satan, although Yazidis themselves maintain that Melek Taus is a separate being. Defining features in game:
- Yazidi rulers can - and are expected to have - multiple wives.
- Temple Holdings can be held by anyone without penalty.
- Yazidi dynasties grow decadent unless the men have enough land and win wars.
Yazidism is a heresy of Sunni Islam.
