He also meets Reyna, the praetor (leader) of the camp, who recognizes him as an old friend, but Percy does not remember her. He also meets Octavian, an augur (priest) who dislikes him and tries to sabotage his chances of joining the camp.
War Games and Receiving a Quest
Percy participates in a war game against the other cohorts and impresses everyone with his skills and leadership. He is accepted into the Fifth Cohort and becomes friends with Hazel and Frank.
He also learns that he is part of a prophecy that involves seven demigods from both camps who have to stop Gaea from waking up her giant sons and destroying Olympus.
He receives a message from Juno, who tells him that he has to go to Alaska, where Thanatos is being held captive by Alcyoneus, one of Gaea’s giants. Without Thanatos, no one can die or stay dead, which gives Gaea an advantage over the gods and demigods.
Departing Camp Jupiter
Percy decides to go on the quest with Hazel and Frank, who volunteer to accompany him. They leave Camp Jupiter without permission from Reyna or Octavian, who try to stop them. They also take along a harpy named Ella, who has a photographic memory and can recite ancient prophecies.
They board a plane that is piloted by a storm spirit named Arion, who is Hazel’s horse. They fly to Alaska, which is beyond the gods’ control and where the sun never sets.
Portland and Seattle
Along the way, they encounter various obstacles and enemies, such as Amazons, griffins, basilisks, and Laistrygonians.
They also meet some allies, such as Iris, the goddess of the rainbow, who runs a health food store; Phineas, a blind seer who can see the future with the help of a harpy’s blood; and Hylla and Kinzie, Reyna’s sister and niece, who are the queen and princess of the Amazons.
They also learn more about each other’s histories and secrets, such as Hazel’s involvement with Gaea and Frank’s family gift.
Learning the Family Gift
Frank discovers that he is a descendant of Periclymenus, a grandson of Poseidon who had the ability to shapeshift. He inherited this gift from his mother, who died in a fire caused by Gaea. His father, Mars, gave him a piece of wood that contains his life force.
