Experimenting with the idea of a green Uvirith I found that this texture was used under the tower. I thought that it actually went quite well with the environment surrounding the area and could be easily explained. (For example it could be said that the mixed efforts of enchanters and farmers planning to migrate to the area.) I was wondering what everyone else thought.
