Psyche

Psyche is a mortal woman who fell in love with Eros and was forced by her mother, Aphrodite, to earn her way back to him. She was then rendered immortal, and became the Goddess of the Human Soul (due to her being able to understand human suffering better than any other god). She was married to Eros, and soon gave birth to Hedone, the Goddess of Pleasure.
