Human: Generate for me a description of a dark scene inside a tunnel mine with an oil lamp, pick, and sandstone walls. Assistant: 
Half-collapsed scaffolding tilts precariously, left behind by tunnelers more intent on finishing their task than on cleanup. Yellowish sandstone walls scarred with pick and shovel marks arch overhead, the dark shadows pooled at their apex out of reach of the tentative beams cast from an oil lamp set on a wooden shelf.
