Write a detailed description of a gloomy scene inside of a medieval keep with a jumble of boulders and a ragged ceiling.

A jumble of boulders is piled against the far wall where the hallway dead-ends. The ceiling has dropped, its ragged surface little higher than a dwarf near the impasse. Light barely intrudes into the half-gloom, casting uneven designs on the walls. The air is still and dusty, lacking the currents which breathe a better atmosphere into the more finished hallways of the stone fortress.
