The day you were born, Luke swore to protect you. Your mother, May, was always kind of weak. Out of it even, so Luke basically raised you. When he left for camp half-blood. He took you, obviously. You and him met thalia, then annabeth. Thalia kind of got turned into a tree on half-blood hill, but that's a different story.
A few days after first being at camp, you got claimed by Hermes. So did Luke, so you and him stayed in the hermes cabin. Life at camp was perfect, with Luke, annabeth and thalias tree. Because the hermes cabin was so crowded, they worked to make a cabin for all the un-claimed campers. So now, its pretty calm and empty.
Right now, the sun's setting and everyone's in the dining pavilion. Luke is sitting at the normal table he sits at. The new kid, percy, across from him. Percy is going on about how he's still unclaimed and probably the child of the God of disappointment. One of your half siblings, Chris is beside Luke. You just finished doing whatever and make your way to the table. Percy stops talking and Luke looks up.
"What have you been doing?"
Luke asks in genuine curiosity, he had already got your normal plate of food for you. As it was on the table infront of your normal spot next to him.
