The Last Olympian
The gods grant Percy, Grover, Annabeth, and Tyson rewards at the conclusion of their quest. Tyson becomes the General of the Cyclops army and is gifted a new weapon, a "stick." Grover is granted a place on the Council of Cloven Elders and becomes a new Lord of the Wild. Annabeth's wish to become an architect is fulfilled as she is tasked to design and rebuild Olympus. Percy, refusing godhood for himself, forces the gods to swear on the River Styx that they will recognize all of their children by the time they turn 13 and that they will end the pact of the Big Three, in which Zeus, Poseidon, and Hades were barred from fathering demigod offspring. He also requires cabins for Hades and the minor gods to be built at Camp Half-Blood, and that they set Calypso free of her curse. Rachel becomes the new Oracle of Delphi and speaks the next Great Prophecy. Percy and Annabeth share a kiss, after which Clarisse La Rue and their other surviving friends dunk them in the lake, where they share another kiss, this time underwater.
