Hero and Ariadne develop feelings for one another during their journey to Olympus. Meanwhile, Lykos and Aegeus are back in Athens being held in dank prison caves where they must hide their identities, or suffer the terrifying rage of the other inmates.

Hero, trapped in the frozen palace, has a chilling vision of Gaia informing him that he'll die if he attempts to enter Olympus. Trying to escape this fate, he comes to the realization that in order to survive he'll need Medea's faith in the gods, Daedalus' scientific genius and Oracle's visionary gifts.
