This is arguably the most lore-heavy story in the collection. Set in the Underworld during the winter solstice, Persephone summons the three most powerful demigods of the era—Percy (Poseidon), Thalia (Zeus), and Nico (Hades)—because they are the only ones who can enter the Underworld and survive the journey. The Threat: Hades' new magical sword has been stolen by a secret demigod spy.
