The party cautiously approached the main chamber of the Pits: the Workhouse. What was once the central hub of a long-abandoned mine has been converted to a labor camp. With a ceiling some 50 feet high, and overlooked by the guard room above, escape or revolt seems almost impossible. And to make matters worse, the center of the room features a stalagmite some 30 feet high buttressed with a wooden scaffold and topped with a shuttered, wooden structure. Ropes from the ceiling connect to the shack, possibly alarm ropes.
The floor of the chamber is crisscrossed with mining tracks and carts, leading to wooden pens filled with stone. From these, rock is removed to tables manned by slaves, who break the lumps and separate chunks of whitish material from the debris.
Four human guards patrol and oversee the operation, one armed with a scourge to encourage productivity.
The party burst into the room, careful to avoid harming the slaves, but quickly overwhelming the surprised guards. In only a few moments the battle was over, and the party turned to deal with the foreman.
