Persephone

Persephone is a daughter of Zeus and Demeter, a personification of the annual cycle of vegetation and the queen of Underworld. She is married to Hades and is mentioned in Skin Game.

Description
Persephone married Hades by her own will, and her mother Demeter failed to cope.

Skin Game
In Skin Game, Hades mentions that the three pomegranate seeds are a fiction to assuage Demeter about her daughter's marriage to him, and that Hecate led Demeter around, so that Hades and Persephone could enjoy a honeymoon without Demeter's cumbersome presence.
