Fics like The Will of the Crusaders

One touch of the book turned the kind, eager, wise young prince into a demon incarnate. Prince Julius, ever so eager, did not waste any time in seizing the throne, and Archbishop Manfroy was all the happy to indulge him... As Julius stages a coup on his father almost immediately after receiving the Book of Loptous, and lets the Loptrians invade Belhalla, the Second Holy War begins in a frighteningly quick turn of events. Lives are turned upside down and families are ripped apart, as the Loptrian Empire is reborn for all to see. The Crusaders have to rise once more, for the people, and for their future. "To inherit a holy weapon does not make one a hero. To carry on the will of the Crusaders is the true measure." (FE4 Gen 2/FE5 AU Novelization/Canon Rewrite)
