The pillars of peace were shattered when an army of abominations, summoned by The Ten Necromancers, burned the last great city to cinders. Any hope for victory quickly faded away as the few that survived fled for their lives to the eastern forests, vast mountain ranges, and coastlines. There they established small fortified encampments and hamlets in hopes of one day replenishing their numbers enough to strike back against the undead creatures that now dominate the land.
Colossal Calamitous - The Death Of The World
It has been half a century since The Ten Necromancers summoned the great rotting Calamitous - creatures ranging in size from that of a horse, to gargantuan monstrosities that loom over even the tallest of towers.
While none have laid eyes upon the Necromancers in decades, the detestations they created still roam the lands today. Cursed to traverse until either the rot overcomes the dark arcane power that animates them, or they are stopped by force, which is certainly no easy task.
These creatures leave only death in their wake as they slice their way through once-green valleys and long-dead plains carpeted with husks and dust. They traipse through ruin and abandoned city as if they were mere brush in a thicket, and they wade through vast lakes and rivers as if they were but puddles and streams.
