This map is absolutely amazing. I think it might be the coolest map that I've ever seen. Nice job working with all the different XML to make this.
Couple of things I noticed on the map:
You never say what symbol denotes a Blood Tower. It takes a very long time figure out what a Blood Tower is just by looking at the map. You kind of have to do process of elimination and figure out that everything else means something else and the words "Blood Tower" are kind of close to the little black and red symbol in one corner of the key. I would think that should be labeled more clearly, perhaps where you define the other territory types.
The reason I was even looking for the Blood Tower is that I was trying to figure out what the deal was with the Forbidden Lands. As it stands now, it's really unclear what the interaction is between the Blood Towers and the Forbidden Lands. If you mean that you have to control 2 territs that border a Blood Tower in order to attack the Forbidden lands, then why not just say that? As it stands now, there are a few problems with the wording. First there are no "territories that border 2 Blood Towers" that I can see. Second, I am unclear on what "its impassible borders." Does that mean that you have to hold 2 Blood Tower-bordering territs in order to attack the Forbidden Lands? Third and much more minor point is that "borders" is misspelled down in that same area.
Also, I spent a long time trying to figure out where the asterisks along the right side were trying to lead me to. I finally figured out that the asterisks refer back into the middle of the panel second from left. This is hardly an intuitive place to look for what an asterisk means. I would suggest copying the asterisk definition (by this I mean the "* = each" text) and putting it also at the bottom right of the map, where people will naturally look to find out what the asterisk means.
Anyway, that's all I see from the visual/understanding part of things. I'll let you know if I find any problems with the gameplay.
