Running Water ~A Jercy Fanfiction~
Jason is the captain of the Track team, known as the 'Legacies'. His best friend is a girl called Annabeth Chase, an expert in architectural design and facts in general. She's his second in command on the team, and is feared by most of the school due to her infamous death stare.
The Half-Bloods are the swimming team, who have never gotten along with the Legacies. The two teams often have arguments and fights that resulted in serious injuries. Their captain is a guy called Percy, who's best friend is Pipe McLean, he has an enormous Rottweiler called Mrs O'Leary and, most importantly, he despises Jason and anyone associated with the Legacies.
