Evan, a burned-out programmer, is ripped from reality and thrown into a corrupted world where magic runs on code and reality glitches like a broken simulation. Branded as the Error Code—a living anomaly—he finds himself rewriting the world just by existing. Hunted by a system that sees him as a threat and guided by a mysterious mage named Lirien, Evan must learn to control the unstable magic within him before the world collapses under the weight of his presence.
