Cataclysm shattered the world, bringing monsters and the System that stripped away technology. Classes and skills became humanity's only defense—until Devon received the Blacksmith class, a designation that offered no Intelligence bonus. Once a mathematical sociologist, Devon watched his former expertise crumble as he joined the forgotten production classes, rendered obsolete by the System Shops that dominated trade. Yet Devon refused to accept obsolescence. What if he could weaponize scientific thinking against the System itself? By merging mathematical precision with blacksmithing craft, he discovers unconventional paths to power that the System never intended. As Devon forges his own destiny, he challenges the very mechanics that govern this new world—and discovers that intelligence takes many forms.
