Twelve years have passed since the second Nightmare invasion began.
The number of level-10s from the Nightmare World deployed to the Shadow Battlefield surpasses the Alliance Army by a third, making their onslaught exceptionally savage—a direct and relentless advance.
Battered by the ferocity of the Nightmare, the Alliance Army can only hold the lines for now by relying on the Shadow World's will, defending with the advantage of the terrain.
