What would happen if a whole world was isekaied...? One nation's folly spelled destruction for us all. As the Cataclysm ripped across the old world, the various warring nations banded together in one last ditch effort. After the portals that carried them to a new dimension were constructed, humanity was forced to travel through, leaving everything they once knew behind.  Even magic. Now, hundreds of years later, a new breed of adventurer has appeared. Those brave few who dare to chart the warped terrain of the old world. Those who would snatch old magics from archives, ancient artefacts from dungeons.  They call them Delvers. And Julian Renning aims to join their number.
