It was a normal day at camp half blood, Apollo kids playing basketball and satyrs running into trees.
The giant war was over and Percy Jackson had killed Porphyrion and Polybotes all while the Gods could not help because of split personality. After the war the two camps decided it was best to stay away from each other except the seven they sometimes travelled between camps. Frank, Hazel, Percy, Annabeth and Leo were at CHB while Jason and Piper were at camp Jupiter.
The day went on as usual until about six pm. An Aphrodite camper came running to Percy saying there was a camper at the border. He got up from dinner and went to the top of half-blood hill where there was a boy with electric blue eyes and blond hair fighting off a hell hound with a celestial bronze sword in hand. He dodged a paw the size of a refrigerator and stabbed the sword through the hound's neck. In a poof of golden dust it was gone. The kid looked up the hill and yelled: "did you see that"! He came running up the hill and the second he stepped through the border he had a lightning bolt glowing above his head.
Chiron came galloping up the hill and shouted: "all hale the son of Zeus"! And bowed his head in respect. As did all the campers who were watching the events unfold. "What is your name son", Chiron asked.
"Jake" the son of Zeus replied.
"What is your age"? Asked Chiron
"Eighteen" was his reply
" All right Percy here will explain everything and show you around".
