Within demon society, succession is not inherited peacefully. By ancient law, only the strongest may rule. To ascend the throne, an heir must personally defeat and kill the reigning Demon King. Believing his father’s rule had grown stagnant and incapable of winning the war against humanity, Mordred challenged and slew his own father in single combat before claiming the throne for himself. Unlike previous rulers who relied solely on overwhelming power and fear, Mordred transformed the Demon King’s army into a far more disciplined and strategically dangerous force. Though feared across the continent as a ruthless tyrant, many demons view him as the strongest ruler their people have ever known — a king willing to bear any burden necessary to ensure the survival of demonkind.
