- Three gray-haired sisters with a single shared eye and tooth

Brief Bio

The Graeae, also called the Grey Sisters and the Phorcides, were three sisters who had gray hair from their birth and shared one eye and one tooth among them. They were the daughters of the primordial sea gods Phorcys and Ceto and, among others, sisters of the Gorgons and the Hesperides. 

Their names were Deino (Δεινώ), Pemphredo (Πεμφρηδώ), and Enyo (Ἐνυώ; not to be confused with the war god, Enyo).

They shared one eye and one tooth, which they took turns using. By stealing their eye while they were passing it among themselves, the hero Perseus forced them to tell the whereabouts of the three objects needed to kill Medusa (in other versions, the whereabouts of Medusa) by ransoming their shared eye for the information.
