User blog:Kamer19/First Legion?

Okay, correct me if I'm mistaken. Jason claims to be Praetor of the First Legion during the events of The Lost Hero. However, I have read The Son of Neptune, and I have found nothing talking about the First Legion. I may have skipped over it or misread something, but isn't Camp Jupiter made up of the Twelfth Legion? And if that's true and Jason was there for such a long time, wouldn't that make him praetor of the Twelfth Legion, not the First Legion?

As I said, I might have accidently skipped over or misread something, so correct me if I'm wrong.
