This is the political map which we'll be using for BGTW 3, as it can be seen in the very first post of this thread (the only possible difference is that the Arabs might eventually be invading as a horde to represent the second Arab siege of Constantinole, but that's not yet certain):
The map of Tsar Simeon's Bulgaria is obviously from a far later date and, I fully agree with Kavhan Isbul, has some rather big inaccuracies regarding the lands to the north of the Danube. As for the "territorial gains during Tsar Simeon's reign", let us not forget the border marking inscription of Narǎš f.e. Anyway, this version of the map seems to show the situation a bit better, although (again) it has nothing to do with the BGTW maps, since we don't have a campaign set in Tsar Simeon's times (for now, at least).
