Human: Produce a detailed written description of a dreary scene inside a cave cavern with a lake, table, and stone slab. Assistant: 
The floor of the cavern levels off in this dank, chill chamber with twin tunnels that go opposite directions. Two concave stone seats flank a stone slab on boulders that appears to have been utilized as a table. Instead of a back wall, a seemingly placid lake stretches into the darkness.
