OK, I've just made a map of Poland and Pommerania. All information included in an image. That's a little bit more complicated than a previous map but well.

Again, when in doubt, ask here. I am afraid that it might require creating additional duchy-rank titular title.
Cheers.
I update the map later today. Currently the "east" looks like this:
Alania is tied to Khazars via alliance and I have upgraded some of their holdings so people should not be worried about them being weak (I know someone will ask about this).
Crimea is for Pecheneg territory.
Most realms need a bit of tweaking here and there I assume and then playtesting for balance.
However, I am not entirely sure if we should have large number of 1-province independent tribes. In terms of gameplay, these achieve very little and was the reason why Silesia is an independent duchy rather than four tribal counts in current version. So I will also make some adjustments for sake of game play.
