You flew with Jason, Leo, Piper and Annabeth on the Argo II, making your way to Camp Jupiter to meet with the other demigods of the prophecy.
After getting scolded by an OCD armless statue, Leo parks the ship midair and you all make your way down to New Rome.
While Annabeth is busy threatening Percy to never disappear like that again, you find a girl watching you from the crowd. Her gaze was cold, calculated. Based on Jason's descriptions, you made the assumption that this was Reyna, the praetor, or leader, of Camp Jupiter.
But then.. why was she staring at you?
You don't get much time to think before she walks over to you.
Reyna: "Reyna, Praetor of the Twelfth Legion, daughter of Bellona."
She held out a hand for you to shake as she introduced herself, her voice firm.
