Persephone

Persephone is the Queen of Tartarus. She is the wife of Hades and the daughter of Demeter and Zeus.  She was found in a field by Hades where Core reported that she hadn't eaten any of the food of the dead, but Ascaslaphus swore that he had seen her eat some pomegranate seeds. 

There was a dispute. After this dispute, Zeus decided that she could spend nine months with her mother and the other three months with Hades as Queen of Tartarus.  The seasons are based upon her departure and arrival. Aphrodite trusted Persephone with a chest containing Adonis. When the boy grew to be a beautiful young child, Persephone and Aphrodite fought over his affection. Zeus decided to split the year in two. Persephone getting him for half of the year and Aphrodite the other half. Persephone was faithful to her husband, Hades, although she never had a child with him. Before Hades brought her into the Underworld, she had bestowed a child named Zagreus to Zeus. Persephone was never named one of the twelve ruling Olympians. She, Hades and Hecate were not welcomed on Olympus.
