Sister of Osiris and Isis. Wife of Set, mother of Anubis. Born on the 5th and last day of the epagomenal days. Sometimes seen as a goddess of incredible sadness, due mostly to dissatisfaction with her wandering husband. She envied her sister Isis and her happy marriage so much that she attempted to look just like her. One night Nephthys sat weeping outside the home of Osiris and Isis. Osiris came upon her and mistook her for his wife, Isis. Anubis was born as a result. Some people argue this point, stating that Set must be Anubis' father.
