A war has broken out between Auros and Magis. Claude, a Esper user with his Aestus blade must restore balance back in Khloeheim by sealing all Auras back into their places. They encounter Gilgahymn, an old immortal ruler, past rivals of all Claude's successors of magis including his bloodline. Gilgahymn seeks to balance Auras and Magis into an equal universe. Claude and his gang must seize and track down Gilgahymn before the prophecy, which is the third War Of Faith, the darkest war, breaks out once again, and drags all Magis, Auras, and Espers into the depths of dark valleys of unknown pain.
