Fates' Intervention

Following the fulfillment of the Great Prophecy, the Fates decide that the Olympians' stubbornness is going to be the end of everything, and there won't always be a demigod around to help. So they force some quality family bonding time in the hopes that things might change. Percy just wants to know why it's always him. Time travel. If you don't like Luke, this may not be for you.
