Isis

Isis is the Egyptian goddess of magic. Her Greek name is Ἶσις. She is born during the fourth day of the Demon Days. Her parents are Geb, the god of earth, and Nut, the goddess of sky. In her first life, she is the sister of Horus, Orisis, Nephthys and Set. However, in the next life, she is reborn as Osiris's wife and Horus's mother. In The Red Pyramid, Isis is freed with Osiris, Nephthys, Horus, and Set by Julius Kane and Isis hosts Sadie Kane. In the end, Isis and Sadie reach a point in which they both control Sadie's body, but Sadie asks Isis to leave and she does.
