Human: Generate for a spooky scene outside a town market with produce, a sewer grate, and oaken beams. Assistant: 
Broad oaken beams support the flagstone foundation of the street overhead, where a barred sewer grate in one corner provides easy entrance and exit to the surface. A rancid reek rises from piles of discarded produce dumped here by the bazaar vendors above, which discourages any curious surface dwellers from paying this area too close attention. The sewer tunnel slopes steeply downwards to the southeast beyond your vision.
