Desertification has been ravaging the continent of Vainqueur, forcing the two major countries of Alistel and Granorg into a war over the remaining fertile land. We play as Stocke, a special intelligence operative for Alistel. One day, Stocke receives from his boss what appears to be a blank book—but turns out to be a magical artifact known as the White Chronicle, which allows Stocke to travel through time. Teo and Lippti, children who act as advisers to the holder of the White Chronicle, warn Stocke of the world's inevitable destruction from desertification and task him with stopping it.
