"The final battle is just the beginning." Jacob Riverson, Regina Whitetremor, and Serah Brightwaters have assembled the greatest army the Northern Wasteland has ever achieved but it still may not be enough. The tyrant, Empress Morwen, has gathered all of the forces of the Southern Continent to invade along with an army of airships as well as enslaved divine spirits. It is a battle that will determine the fate of all Three Worlds. But is the battle a cover for something much worse? After a horrifying disaster, Jacob is left broken and injured in a way that he's never felt before. His powers weakened and his spirit spent, he receives an offer that he cannot afford to refuse. But this deal comes with allies he cannot trust and a cure that may be worse than the disease.
