An Injured Knight

Carson and Herrold both led the way while the private soldiers stayed behind them. They were all wielding their guns, pointing them toward the endless darkness. On the side of the walls, they notice that were are unlit torches, all just hanging around, waiting to be lit.

They walk over to examine them closely and see that they were all burned a bit, but not enough for them to diffuse. Carson and Herrold start lighting them up again, brightening the caves and increasing their visibility. 

As the rooms got lighter, The soldiers were spooked upon seeing the rotting corpses of demonic monkeys, the singefurs, all over the place. The musketeers all observed them to be holding pickaxes, with broken gems on their foreheads. In the middle of the rooms, were cast iron rails, resting on wooden plank sleepers.

On the rails, themselves were minecarts, filled to the brim with metal ores and coal, just mixed up, ready to be carried away to the cave entrance.
