Mandaeism

In Mandaeism, the World of Darkness (alma d-hšuka), also referred to as Sheol, is the underworld located below Tibil (Earth). It is ruled by its king Ur (Leviathan) and its queen Ruha, mother of the seven planets and twelve constellations. The great dark Ocean of Sup (or Suf) lies in the World of Darkness. The great dividing river of Hitfun, analogous to the river Styx in Greek mythology, separates the World of Darkness from the World of Light. Prominent infernal beings found in the World of Darkness include lilith, nalai (vampire), niuli (hobgoblin), gadalta (ghost), satani (Satan) and various other demons and evil spirits.
