In the shadowed depths of the Abyssal Scar, a Korean soldier named Baek Seung-ho dies—and awakens in the body of a tribal warrior, raised in darkness and forged into a living weapon. Seventeen years later, known only as Aran, he ascends to the surface: an overpowered barbarian who doesn’t know his own strength and wants nothing more than to explore, fight, and chase the horizon. But the surface is a world of scheming empires, slumbering evils, and gods who treat mortal lives as pawns. Unfortunately for them, this carefree iron-blooded wanderer is about to shatter every expectation—whether he realizes it or not. After all, what is a man who doesn’t know his own strength, except a storm waiting to be unleashed?
