Human: Generate for a foreboding scene outside a clearing with a pool and a well. Assistant: 
A suffocating stench, like the foul gasses released from especially deep and ancient bogs, rises from a wide circular well in a blighted clearing some forty feet beneath the vine bridge. The cracked and broken stone of the well's wall has been overrun by a thick, viscous fluid which seeps from the interior of the well, spreading across the clearing like a malignant ink stain. Rotting trunks and withered vegetation border the edges of the diseased pool.
