Kharon, this is some great work you've put into the background and understanding of Atrusia. Looking at your climactic regions I have a question. Is there a geological demarcation between the western and west-central areas? There seems to be a fair difference in rainfall based upon the greenery you have denoted. Coming from the west coast of the U.S. I'm familiar with that as being the presence of a mountain range but I don't really see much of a range along the line you show. Is there a significant change in elevation that would account for this? Reading back over what you wrote above I suppose it could simply be a difference in soil quality. The only reason I ask is that you have put so much time into understanding the region that I'm looking for a reason that's not readily apparent to me.
