500 years ago, Percy Jackson was accused of aiding Gaea in the Second Titan War. As consequence of that, he was killed to show people what happens when you betray the gods. But the gods learned that they were wrong as Chaos came after Percy's death and informed them of his innocence. But actually, Percy's alive with Chaos. War's here and a disguised Percy comes to help, who'll win?

AU. The first time Athena laid eyes on Percy, she knew he would be great. He became her companion, the son of her nemesis, but somehow her most faithful champion. The Ancient Greeks knew him as Aegis, Athena's "shield," for where he goes, Death follows. And they say that he would do anything for his Lady... even at the cost of his immortal life.
