Human: Please generate a dreary scene inside of a medieval factory with doorways, scrap bin, and a pounding sound. Assistant: 
Soot-stained red brick makes up the walls and floor of this large hall. Other than a scrap bin placed at the south wall, the hall is otherwise unfurnished. On the west wall are three archways, through which the sound of pounding metal can be heard. On the east wall are three doorways, blackened with coal dust.
