Apsu

This was the god of the Underworld Ocean, the father of the skies and the earth. He had four children, Lehamu, Anshar, and Kishar. He could not overcome the noise of them or their children. He plotted with his vizier (a high government official in the empire), Mummu, to quiet the gods and allow Tiamat to rest. Ea discovered his plans, cast a spell on him and killed him.
