Phratagounè (died c. 429 BCE), also known by her epithet the Keeper was a member of the Order of Hunters, a branch of the Persian Order of the Ancients, active in Makedonia during the peak of the Peloponnesian War.
While the Peloponnesian War raged in Greece, Phratagounè was one of a handful who followed the Magi of their branch, Pactyas the Huntsman, into Makedonia, hunting for the "Tainted Ones", including Darius and his only surviving son, Natakas.
Recluse by nature, Phratagounè preferred to live away from civilization in the company of her animals, admiring them for their loyalty and inability to lie. At some point before 429 BCE, Phratagounè grew close to Pactyas, so that during their time in Makedonia he entrusted his animals into her care. She trained them to be loyal so that when the time came, they would kill the 'Tainted Ones' without objection.
- Phratagounè shares her name with one of the Persian King Darius I' consorts.
- Before being revealed as an Ancient, Ikaros identifies Phratagounè as a Beastmaster.
