I'm not sure of the exact plot, but it could be that there is a threat to the fabric of time itself. Percy and Athena are chosen as the 'timeless warriors' to combat this threat. The fanfiction might show how they use their combined skills and knowledge. Percy's experience in dealing with on - ground challenges and Athena's strategic thinking. They might travel through different time periods, gathering allies or artifacts that are necessary to stop the evil force that is messing with time. And in the end, they succeed in restoring the balance of time, and their relationship has also evolved into a strong bond.
Since I haven't read this specific fanfiction, a possible plot could be that Percy and Athena are brought together by some ancient prophecy related to the 'timeless warrior'. They start off not really trusting each other due to their different backgrounds. Percy, with his demigod powers, and Athena, with her godly wisdom and powers. As they embark on their journey, they encounter various mythical creatures and obstacles. Along the way, they learn to understand and rely on each other more, and ultimately, they fulfill the prophecy and perhaps bring about a new era of peace or something similar.
