Son of Geb and Nut. Brother of Auset, Nephthys, and Ausar. The husband of Nephthys (Auset twin sister) . Man with the head of an animal. Some times he takes the form of a crocodile. Seth is the god of evil, of drought, of destruction, thunder and storm. Seth tore himself from his mother's womb in his hurry to be born. Every month Seth attacks and devours the moon, the sanctuary of Ausar and the gathering place of the souls of the recently dead.
Jealous of his older brother Ausar - either because of the birth of his sister-wife's son, Anubis, or because of Ausar rulership of Egypt -- Seth made a plan to murder his childless brother and take the throne. When Auset found out about this, she went on a search through the world to find her husband. Bringing him back, Seth happened on the coffer, and tore it open and cut up his brother's corpse, spreading body parts through the land of Egypt. Auset and Seth's wife Nephthys (who had left him to join her sister) went on a quest to restore Ausar. They succeeded enough so that Auset conceived Ausar's son and eventually bore the child Heru in the Delta region where he grew up.
By this time Heru had reached manhood ... Heru thereupon did battle with Seth, the victory falling now to one, now to the other ... Heru and Seth, it is said, still do battle with one another, yet victory has fallen to neither.
