This article is written from a real world point of view.

The Great Prophecy

A half-blood of the eldest gods

Shall reach sixteen against all odds

And see the world in endless sleep

The hero's soul, cursed blade shall reap

A single choice shall end his days

Olympus to preserve or raze.

This prophecy unravels throughout the series:

  • Percy Jackson is a demigod child of Poseidon, one of the six eldest gods born of the Titan Rhea, wife of Kronos.
  • Percy reaches sixteen despite all of the numerous times he was almost killed by Luke Castellan/Kronos and his monsters.
  • Percy finds the whole city of Manhattan asleep from Olympus, so the war can go on without any of the humans interfering.
  • Luke Castellan used Annabeth's knife to kill himself to stop Kronos. This is the same knife that he gave her when she was little. He promised that they would be there for her and that they (including Thalia) would be a family. When Luke broke his promise to Annabeth, her knife became a cursed blade.
  • Percy had to choose between giving Annabeth's knife to Luke and allow him to destroy himself or trying to destroy Luke himself. Either choice would have resulted in Luke's death however.
  • Percy's choice would result in the either the destruction of Olympus or its preservation.
