Hello!
First of all good luck with your project, guys!
You are doing an amazing work here and a beautiful conversion to medieval asian world.
Also I love the idea of mongol invasion, will they be a force in this part of the world ?
I mean, they will they a bit superior with their troops, organization, culture, moral ?
Genghis Khan will have to unite the mongolian tribes before starting expending in the South and East ? Perhaps some of mongolian tribes could be represented by regions controled by rebels ?
