Radiant Historia

In the midst of an unending war for dominance between two super-powers, Special Intelligence Agent Stocke is assigned to a routine escort mission that goes horribly awry. However, wielding a mysterious book called the White Chronicle, Stocke discovers a way to travel to the intersection of time itself: Historia. With this power in his hands, he must travel back and forth through key events and an entirely alternate timeline to right the world's ill-fated course. The lives of his companions, the fate of nations, and the resolution of an impending disaster that now threatens the land all depend on Stocke's ability to discern the one `true` history.
