Not strong of body, and questionable of mind, she has a kind heart and one special talent. She is not a healer of wounds, or even of people, she heals the souls of creatures. She feels sympathy for even the most hideous and terrible of creatures, and when her tears for them fall upon them, their hearts are moved and their evil ways ended(for a little while at least).
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.
