Please generate a brief description of a dangerous scene inside an armory with a lava floor and grindstones.

Metal shrieks against stone as the grindstones spin. The industrious forge attendants, who bustle about while seeming not to move, keep the black, pitted lava floor clean. Muffled pounding sounds from elsewhere in the forge, and a wall of heat comes from the foundry to the northeast, but this grinding room is a relative oasis of coolness in the granite building.
