One thing that has always bothered me is that, we know the Blood and Ash Legions have their own territory on the other side of the mountains to the north and east of Ascalon, but just how large ARE those territories? Iron controls all of Ascalon, but do we know anything about how large the area they rule is? If its a similar size to that of Ascalon themselves? I couldn't imagine the other Legion not having similar territory sizes given how much they constantly try to stay on top of each other.
It has always seemed odd to me that the Charr's "empire" or w/e you want to call it could make them the worlds preeminent superpower, but its always just sort of ignored and they just sort of act as if Ascalon is all they have.
Its even odder when you think about how the Charr Homelands area we visited back in EoTN was treated like it was super backwoodsy, on the fringe of their territory.
