Human: Generate for a gloomy scene outside a wilderness stream with a rotten footbridge. Assistant: 
Sloping down to the edge of a stream bank, the trail ends abruptly at a rotten wooden footbridge. The footbridge once provided passage over the large stream, but now has rotted to the point of being unusable. The water has dried up on this side, but near the other bank, a black sludgy liquid moves languidly to the east.
