Also, would the Balseraphs be content with region 27, and the Malakim with 36? That would make the map quite well spread out.
EDIT: The terrain map will not actually be used for the borders or Factions. I've discovered that, either by Immaculate's intent or a lucky accident, hiding the feature's layer gives a very nice blank map that will work well as a political map, showing nations and traderoutes. I will keep a terrain map up in the OP for reference, which won't need to be updated unless I decide to show settlements on it.
