By his wife Ninlil or Sud, Enlil was father of the moon god Nanna/Suen (in Akkadian, Sin) and of Ninurta (also called Ningirsu).
As Enlil was placed in command by An, the god of the heavens, he held sway over the other gods who were assigned tasks by his sukkal, or attendant, and would travel to Nippur to draw in his power.
