Inanna was a Goa'uld and the sister of Eresjkigal.
Biography[]
She ruled the moon Sargon and her sister Eresjkigal ruled its twin Ganzir. The two siblings spent generations at war. Her sister, aided by Enki, defeated her.
According to a temple relief examined by Lanni, Eresjkigal celebrated her victory by consuming a serpentine creature, which may have been Inanna's symbiote. Lanni couldn't determine if it should be interpreted literally or symbolically. (RPG: "Core Rulebook")
