Side was the first wife of Orion. When married to him, she offended Hera and was sent down to the Underworld. Her name means 'pomegranate' (side), a fruit that has links with the Underworld, since it was the
food that
Persephone had thoughtlessly eaten there when she should have eaten nothing (for Demeter to be able to win her back from Hades, who had carried her off there).
