Anunnaki
Anunnaki (Anunna, Anunnake, Ennuki) : In Near Eastern mythology (Babylonian), gods or spirits of the underworld, opposed to the Igigi, the heavenly gods. In the ancient narrative poem Inanna’s Journey to the Underworld the Anunnaki are the seven judges of the underworld. Sometimes, however, they are listed as gods. In the Enuma Elish, the epic of creation, they are the defeated rebel gods who build the city of Babylon for the hero god Marduk.
