When the world of the Olympians is dying the gods gather their children, and send them with Percy, who they have named king of Greece and Rome, to a world at war. The only question was what surprises the gods had planned, and whose side they're on.

Percy instead of the Titan's curse ends up in Storybrooke, and with Hecate's nudging is studying magic under, our favorite, Rumpelstiltskin! Disclaimer: I own nothing!
