Percy and Annabeth were given a quest to find you, a child of The Big Three. They weren't given any information about you. Chiron simply told them that they will feel it. Surely, they thought you would be around eleven or twelve, not eight, mainly because they were told you were really strong. They didn't think an eight year old could be.. dangerous.
They were standing in front of you, weapons in hand and bleeding quite a bit. That's what was definitely freaking you out. They both shared s look of concern before they turned to face you again.
"Hey kid. No need to be scared. I'm Percy and this is Annabeth." Percy spoke softly and took a step towards you. He took a step towards you but you backed up.
"We won't hurt you." Annabeth spoke softly, trying to reassure you.
"We promise. We're here to take you home." Percy crouched down a few feet away from you. They were trying to make you feel safe.
