Human: Produce a detailed written description of a dreary scene inside a keep with rubble and a caved-in ceiling. Assistant: 
Large chunks of rubble and broken glass have rendered this room unrecognizable, although the splintered remains of a pine bed hint at it being a sleeping chamber once. Several of the walls have caved in entirely, opening a way to the southeast. The ceiling has caved in entirely, exposing this portion of the ruins almost completely to the elements.
