Human: Produce a detailed written description of a dreary scene inside a building hallway with an arch, shadows, people, and a floor. Assistant: 
The dim light coming through the arch at the end of the corridor delineates the long shadows of those moving about considerably more than it does the features of the people themselves. The small amount of additional light coming through the doorway halfway down the corridor further accentuates and twists the shadows of those present, playing them across the floor, walls, and ceiling of smoothly polished black stone. Cool moist air flows over the stone leaving it slick to the touch.
