The story goes that the hero Perseus, on his quest to slay Medusa, encountered the Graeae and stole their shared eye and tooth. This act of thievery forced the sisters to reveal the location of the Stygian Nymphs, who could guide Perseus to Medusa's lair. However, this encounter also came with a price: the Graeae were now forced to endure a painful initiation, one that would change their lives forever.
