Human: Make a concise location description of a foreboding scene outside town with a curtain and crates. Assistant: 
Two of the rough wooden walls of the shack lean slightly inward, braced to keep from collapsing entirely by a system of improvised levers and joists. The canvas ceiling overhead dips downwards in the middle, burdened by what appears to be a sloshing liquid weight. Set out of range of any potential drips are two roughly hewn crates. A skewed opening leads out to the front of the shop and a canvas curtain leads out the back.
