Annabeth's Prophecey

You shall delve in the darkness of the endless maze,

The dead, the traitor, and the lost one raise,

You shall rise or fall by the ghost king's hand,

The child of Athena's final stand,

Destroy with a hero's final breath,

And lose a love to worse than death.

Annabeth,

Grover, Percy and Tyson enter the the endless maze, which is the Labyrinth.

Nico raised the dead; Ethan, a traitor, was spared; the spirit of Pan, the lost one, was raised.

'The Ghost King' was Nico, who decided to help Annabeth and the rest of the campers, by choosing to join them instead of Kronos.

The child of Athena's final stand refers to Daedalus dying in order to destroy the Labyrinth.

The Labryinth was destroyed with Daedalus's last breath.

Annabeth loses Luke because he became the host of Kronos, which is claimed to be worse than death.
