Termed the 'lady of the castle,' for her role as guardian of tombs, she sided against her own husband, Set, in his battle against Osiris, but when Set was destroyed, she collected the bits of his body and brought him back to life, much as Isis had done for Osiris. In addition to being Isis' sister, she was also said to be Osiris' mistress, leading to much complaint from Isis. Due to her close ties to all the other gods, she was rarely associated with a cult of her own.
