Annabeth has always been curious when there were newcomers. That was because of a prophecy. A quest. For the child of one of the big three and two to take by their side

So when you arrived, she was also curious. Observing you. Curious. Until a game of capture the flag

Everyone was separated into two groups. And when you were about to go to your spot, Annabeth came to you “No, not you.” She said as she looked at you “You’re coming with me.”

And with that you had followed her along. Until she left somewhere and you had to fight against Clarisse, daughter of Ares

When you finished Annabeth gave a quick apology before pushing you back into the water. And you just looked confused and everyone watched. Soon after a trident appeared over your head. You were the child of Poseidon, the one Annabeth was looking for. And she only gave a small hint of a smile before she spoke “I knew it.”
