The kingdom of Arcadia is burning. Once known as the domain of the greatest magician alive, it now stands on the brink of collapse under the invasion of the Empire. Their greatest weapon is not an army… but an artifact—one that devours mana itself, suppressing even the strongest magic. For the first time in his life, Lee Kiyoung is restrained. His infinite mana still flows within him… yet every spell feels heavier, distorted, incomplete. And in that single moment of weakness— the Empire struck. His parents, the pillars of the kingdom, were slaughtered before his eyes. Now, the throne lies empty. The kingdom is falling. And Lee Kiyoung… stands alone. But even now, with his power disrupted— he is still the most dangerous being on the battlefield.
