What if Percy turned out to de the grandson of Voldemort? What if he and Nico ended up at Hogwarts and now Nico wasn't the one evrione looked at as if he was covered in guts of innocent people? This fiction happens in the 4 book and efther the Gaea (?) war. Nico will be 15 and Percy will be 17 because that the only ages that made sens in the story. Harry Potter and Percy Jackson do not belong to me! Well outside of my dreams that is.
