Graeae
In Greek mythology the Graeae (; English translation: "old women", "grey ones", or "grey witches"; alternatively spelled Graiai (Γραῖαι) and Graiae), also called the Grey Sisters, and the Phorcides ("daughters of Phorcys"), were three sisters who shared one eye and one tooth among them. Their names were Deino (or Dino), Enyo, and Pemphredo (or Pephredo).
