There comes a time when each generation must replace their parents. This is the first time it has ever happened by means other than war. Even so, it's time for our favorite demigods to replace the Olympians as gods.

AU. Fredrick Chase and Sally Jackson both died when Percy and Annabeth were babies. They grow up as siblings, raised by an Olympian goddess and this is the story of how they make it to camp. First chapter is information for the story so please read. Rated T but could change to K or K depending on what you guys think. Pairings have been decided so deal with it.

When everyone left them for their sibling, Percy, Annabeth, Thalia and Nico run away from camp feeling abandoned. Starving, thirsty, tierd, being hunted by monsters non-stop, they meet Chaos, the creator. The four get the chance of a life time. Now meet them 500 years later as the assassins of Chaos. Percabeth and Thalico. Disclaimer: Percy Jackson and the Olympians is not mine!
