Gigantic **portals** tore open, spilling horrific **monsters** across the globe and forcing humanity to undergo a brutal **awakening**. In this new era, where the very air crackles with **mana** and abilities are granted by a mysterious **system**, the world built a fragile peace, believing its new champions were enough.

The world has moved on, hailed new heroes, and forgotten his sacrifice, his name barely a footnote. But he remembers everything: the faces, the lies, the bitter taste of their treachery. What kind of devastating **revenge** will a returned god of destruction unleash on a world that cast him aside?
