Graeae

The Graeae were three sisters in Greek mythology, who shared one eye and one tooth among them. Their names were Deino (dread), Enyo (horror) and Pemphredo (alarm). They were the daughters of the sea gods Phorcys and Ceto, and sisters of the Gorgons. They took turns using their eye and their tooth.

They appeared in the myth of Perseus, who was trying to find out where three magical objects were located, in order to kill Medusa. He went to the Graeae's cave, and stole their eye. He then told them he would return it if they told him where the three objects were.
