The wind picked up to the point where it sounded like a chorus of a hundred howling banshees. Even deep in the cave, we all felt the temperature drop even further as the Chill Squall moved through; snatches of wind fingering in as if it was trying to pluck us out of our hole.
A desolate region is almost entirely without normal vegetation. Local plants are able to unroot themselves and crawl along the ground in search of water and fertile soil. The inhabitants fence their crops in to keep them from wandering off and put heavy stone thresholds in the doorways of their huts to keep wayward plants out.
The plants sense by chemical cues, lacking sight or hearing, and tend to avoid herbivores or anything that smells of "dead plants". Characters with horses are likely to be unwelcome among the locals.
