The Sword of Calamity

Legendary player Rhodes transmigrates into the world of the game Era: Cataclysm.

Starting out as a low-ranking soldier at a border outpost, he awakens a status panel and gains the power of Cataclysmic Plunder: every enemy he kills grants him experience and a new trait.

As winter descends, kingdoms clash, and darkness and turmoil spread, countless versions of the game come and go. Standing atop a throne piled high with corpses, Rhodes finally understands.

The Cataclysm in the game's title was referring to him all along!
