The Palm Tree King was one of the monsters later known as the Slain Heroes in the Sumerian epic, Lugale, which centered on the quest of Ninurta to recover the Tablets of Destiny, which were stolen by the Slain Heroes, from Ninurta's father, Enlil, the god of wind, air, earth, and storms and head of the Sumerian pantheon. The Palm Tree King, in the Lugale epic, was subservient to Imdugud, who held the Tablets until his defeat in combat with Ninurta.
