Intrepid adventurers have entered the subterranean realm known as Tahgrem -- a vast network of caverns filled with deadly traps, ancient magical artifacts, and all manner of creatures foul and terrible.

On the surface world, whispered rumors spread of a growing threat to peace. Some claimed that an ancient dragon, born of shadow, had gained influence among the malevolent throngs of monsters and now sought to lead them against the surface world. Others told a similar tale, but featuring a different villain: a void gazer, whose floating, round form was wreathed with terrible eye stalks, each with distinct deadly powers. Others yet spoke of a mighty undead sorceress whose power ousted control of the land of the dead from its immortal deity. Some tales even told of surface folk being kidnapped and dragged to the dungeons below on the orders of a brain-eating aberration with the ability to dominate the minds of their victims!

One thing was certain, mountain villages had been raided and sacked and whole populations had disappeared underground. Roving bands of orcs, goblins, ghouls, and twisted monstrosities never before seen on the surface had been spotted coming and going from the underworld. Trouble was stirring in Tahgrem. 

Whatever the truth, and whether driven by duty, ambition, greed, or curiosity, our heroes have gone to investigate the Terrors of Tahgrem.
