Notes:

I did some comparisons to Twilight's map and the most recently made fan map and found the borders of King Sombra's empire. Sadly Pinkie Pie's rock farm was taken. But Bright side! it looks like only a few small towns were captured while the primary cities and resource providers are still in the control of Princess Celestia and her EPU guard. The Griffins seem to be having a hard time as well. But at least the Yaks are still free.
