Kiwan

In Mandaeism, Kiwan, Kiuan, or Kewan is the Mandaic name for the planet Saturn. Kiwan is one of the seven planets, who are part of the entourage of Ruha in the World of Darkness.
Kiwan, who is associated with Saturday as well as Judaism, is also called Br Šamiš. Kiwan's name is derived from the Akkadian Kajamānu.
Near the end of Book 3 and at the beginning of Book 9.1 in the Right Ginza, Kiwan is identified with the Kiwanaiia, who are generally equated with the Kentaeans, a related Gnostic sect.
