Harry shows up at camp half-blood. He gets the orientation and meets people. . . Everyone keeps saying he'll be claimed by a god. Then he meets Perseus/Percy. . . According to everyone he's apart of world saving prophecies and is overpowered. Hermine meets Annabeth. Ron meets Grover. Harry and Percy become good friends and are really bad influences on each other (like teaching Harry how to use a sword, to Harry teaching Percy potion and herbology magic)
