“Campers were having flying horseback lessons, swooping over the woods on their pegasi. Smoke rose from the forges, and hammers rang as kids made their own weapons for Arts & Crafts. The Athena and Demeter teams were having a chariot race around the track, and over at the canoe lake some kids in Greek trireme were fighting a large orange sea serpent. A typical day at camp.”

Percy explains some of the common activities that occur at Camp Half-Blood. Many of the activities are geared towards battle preparation, demonstrating the danger demigod children have to face and overcome from a young age. Percy’s lack of surprise at these “typical” events shows that he has become more accustomed to life as a half-blood and the risks that it entails. These preparations will be put to the test in a real battle with permanent outcomes.

“Quintus seemed so nice. So concerned. And Mrs. O’Leary liked him, which had to count for something. […]

I felt ashamed that I could even think about mistrusting Quintus. But then again, I’d trusted Luke once.

‘Thanks,’ I told Quintus. I slipped the freezing whistle into my pocket, promising myself that I would never use it, and I dashed off to find Annabeth.”

Percy suspects Quintus is a spy for Luke because of his mysterious intentions for helping at camp and Juniper’s warning that she saw him near the Labyrinth entrance. Percy naturally tries to see the good in people, but also knows from previous experiences that demigods and gods can have ulterior motives for being kind. Percy has learned to be distrustful of gifts because some have almost killed him in the past; however, when Percy uses Quintus’s whistle as a last resort in Chapter 14, the gift turns out to be helpful.

“Excellent. The voice of Kronos didn’t so much speak as pierce my mind like a dagger. It was freezing with cruelty. Once we have the means to navigate, I will lead the vanguard through myself.

Luke closed his eyes as if collecting his thoughts. ‘My lord, perhaps it is too soon. Perhaps Krios or Hyperion should lead—’

No. The voice was quiet but absolutely firm. One more shall join our cause, and that will be sufficient. At last I shall rise fully from Tartarus.

‘But the form, my lord.’”

In a dream, Percy overhears Luke talking to the un-formed Kronos about his growing power and the invasion of Camp Half-Blood. Dreams are important to the story, as they allow Percy to see places that he can’t physically go and receive important information.
