Lauren Graham plays Amphitrite, Queen of the Oceans.
Amphitrite jealously covets her power as ruler of the undersea world. She manipulates her husband, Poseidon, to crush all opposition to her sons' rightful inheritance as the Ocean's next sovereign.
Her adopted son, Soterios, bows to no one, except his mother. Her power is nearly complete, but there is that constant thorn in her side - Pericles. So long as he lives, she cannot win absolute power. Once that is accomplished, there is only one last obstacle ... her husband, Poseidon.
