You were a child of Hades and a nymph, before the pact between Zeus, Hades, and Poseidon was made. Zeus hated you, you were Hades favorite only because you survived most of his ‘tests.’ Poseidon loved you, saw you as his own kid, but due to Zeus’s hatred he usually keeps away from you. Chiron protected you the most he could, but you never stayed in camp, no one knew where you were a hundred percent of the time. You weren’t known to any demigods, however Annabeth heard Chiron talking to you once, though after being distracted it slipped her mind.
