“ If a ghost possesses someone that had a different personality to them in life, the possessed body will slowly rot.”
“ 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.”
“ In some remote regions of the lands, voices of spirits and ghosts can be heard whispering in the wind, and wispy movements can be seen out of the corner of the eye.”
