Lady Alexin (Alex), the Keeper of the Keys for the Elfin Council of Elders, returns to Eledon to help her grandmother clean out the warehouse, but she's kidnapped and forced to use the magical Keys of Eledon in a series of life-or-death missions with consequences that span the realms. Her initial captor, Lord Fissure of the Rock Elves, demands her magical help, and when she's done, he turns her over to the Marsh Elf Sawgrass, an Elfin criminal, who sends her into the treacherous depths of Hades' kingdom in the Underworld. To save herself, Alex calls upon the powers of Poseidon to help her, but he also needs her help with the Golden Harvest for Olympus. The Mentors will arrive soon for the gold, but only Zeus and Hades know where the gold is stored. Poseidon sends her to find them, so she follows their trail into the mortal world. She must convince them to leave the lives they've established and return to Olympus before the Mentors arrive. Only then will she be allowed to return home to Eledon.
