Betrayed. That is one word that described Percy Jackson. Annabeth cheated on him, his friends despised him, his mom and Paul are gone, and Poseidon disowned him. So he joined Chaos' army. *officially adopted by EpiAsh*

2,000 years ago, Percy Jackson was betrayed by one who he thought was his soulmate, Annabeth Chase. Alone and heartbroken, he ran away with his best friends, Jason and Thalia Grace and Piper McLean. When Chaos found them, they became primordial along with Zoe Nightshade and Luke Castellan. Chaos has now decided it is time for Percy to go back, to the family he still loved... and he might find out a few secrets here and there. Written by xXDaughterOfAthenaXx and Lillianna101

When Percy is no longer a son of Poseidon, but a son of Chaos called Omega, he finds that he has a sister named Jessica who, along with her friends, gets into the army of Chaos. Percy has been betrayed by his fellow campers and doesn't wish Jessica to go to Camp Half-Blood, so he convinces her to become a daughter of Chaos. One day, Chaos gives them a mission that involves saving Olympus, Percy grudgingly agrees. Because every member of the army has to keep their hood on, will Annabeth and Matthew, another son of Poseidon, along with the whole camp and Olympus, find out who Percy and his army are? Will there be a fresh start or will everyone's past determine the future?
