Kai of the Sorcerer's Tower stands among the final mages in a world consumed by darkness, where dead mana has poisoned the lands and magic has faded into legend. Desperate to save his dying realm and honor his master's dying wish, he performs a forbidden ritual—one that threatens to shatter his very soul—to journey backward through time itself. His desperate gamble transports him millennia into the past, to an age when mana flowed freely and magic's golden age hadn't yet begun. But fate proves cruel: he awakens in the body of Arzan, a young lord already marked for death. Thrust into a crisis, he must defend his territory from an impending beast wave while grappling with a murdered predecessor's mysteries and confronting enemies far beyond his current power. In a world where magic and technology remain primitive, a mage from a lost age carries knowledge that could reshape everything. The question isn't whether he'll grow strong again—it's whether he can survive long enough to change the course of history itself.
