Her name means “lady of the castle.” She was another daughter of Geb and Nut, and the wife of the evil Set. Denied a child by Set, she tricked Osiris into fathering a son, Anubis. She was associated with funerary rites, one of the key rituals in ancient Egyptian life. She normally appears as a woman with mummy wrappings for hair.

"Nephthys saith unto the Osiris Ani, whose word is truth:- I go round about thee to protect thee, O brother Osiris. I have come to be a protector unto thee. My strength shall be near thee, my strength shall be near thee, for ever. Ra hath heard thy cry, and the gods have made thy word to be truth. Thou art raised up. Thy word is truth in respect of what hath been done unto thee. Ptah hath overthrown thy foes, and thou art Horus, the son of Hathor."
