Melaina

In Greek mythology, Melaina was a Corycian nymph, or member of the prophetic Thriae, of the springs of Delphi in Phocis, who was loved by Apollo bearing him Delphos. Her father was the local river-gods Kephisos, or Pleistos of northern Boeotia. Her name meant the black suggesting she presides over subterranean aspects. Melaina was also identified with Thyia who is named as the mother of Delphos in other traditions. In some legends, she is called the daughter of Persephone and Hades.
