The son of Poseidon always wanted a normal life, as normal as it could get for a demigod. Of course, the Fates never did like him. It was probably because he didn't have a designed destiny, no, he made his own. The Fates threw everything they had at him, but it was never enough. But now, they have created a plan so vile, so horrific that Tartarus himself would never use it in his torture sessions.
They turned his family against him, the ones who always supported him.
Betrayed, Percy runs away in search of a new purpose. The Fates had planned for him to die a slow and horrible death, but Chaos had taken a certain interest in the demigod. Even with their ability to turn fate their way, not even they can stop Chaos from getting something he wants. And what he wants his for Percy Jackson to become his right hand man. His second in command, his blade, his shield, his legacy.
He wants Percy Jackson to become the Sword of Chaos.
