The Ring

This is not just any other Chaos story. Percy is Betrayed by the ones he loves the most. He loses faith. And then BOOM, everything goes upside down for him. He becomes more powerful than ever. But not immediately, it takes time as in every army.
Follow his journey from Hero to soldier to general to the second most powerful being in the universe.

All the characters belong to Rick Riordan, except the ones that I've created.
