Gaea was finally defeated by the 7 demigods, however before Gaea died she sent her minions to Percy's mother's apartment, and they killed both Sally and Paul. Then SHIELD finds out Percy is actually Tony Stark's long lost nephew. this is a basic tony stark is Percy's uncle story. i also had Pietro live. its after the second avengers movie. enjoy! I can probably write a better summary after I have finished the story.
i own rights to like nothing Percy Jackson characters are Rick Riordans, and the Avengers are from marvel. none of the characters are my own.
