Dungeon Crawl Classics - The Quarry

Doom arrived for the Quarryfolk through a hole struck in the quarry wall.
From this rent a sinuous mist issued forth settling like a caul on the stoneworks. At first Masons piled rocks as it widened, but tendrils seeped through any gap, dislodging stone, and crumbling the mortar set to bar its way.
Under this clutching mist dangerous jobs turned deadly. Many tried to endure these new privations, but they were struck down by a rheumy consumption and departed. Now only the most desperate Quarryfolk remain eking out a living supplying the adventurers who seek the Quarry Owner's rich reward for banishing the mist.
None of these adventurers returned and the mist remained.
Now as winter draws in, necessity has overcome fear and those few desperate souls, armed with little more than the clothes on their back, resolve to re-enter the quarry, vanquish the mist, and claim the reward for themselves.
This is the tale of the last Quarryfolk.
The Quarry is a 0-level adventure compatible with the Dungeon Crawl Classics roleplaying game, and adaptable for any game.
