Human: Make a concise location description of a eerie scene outside a marsh with muck, axles, and a wagon. Assistant: 
The wagon straddles the edge of some subsurface rock, tipping it awkwardly to one side. Sucking sounds from the noisome muck indicate the process is on-going. With its axles leaning to within a hand's breadth of the mire's surface, the wagon looks as though it is being slowly devoured by the swamp.
