Hmmm. A couple things that I've noticed from your screenshots.

I. You spelled it Dragon's Stone... but it's actually Dragonstone.

II. I'm wondering... who are you having rule over King's Landing, Summerhall, Dragonstone, and the nearby territories? The Baratheons, Lannisters, or Targaryens?

Personally, I'd prefer if it were the Targaryens... because that way, the Baratheons and Lannisters wouldn't have vastly more territory. It'd also be accurate for more of Westerosi history, and the Targaryens are extremely interesting.
