I know, there were at least two cities in Mongolia, Avarga first capital of the Mongol empire founded by Genghis Khan and located between the rivers Jerlen and Tsenker and Karakorum (or Jarjorin), second capital of the empire, between 1235-1260, built by Ogodei in central Mongolia, on the banks of river Orjon.
Apart from this, because there will be no cities in the mod, it will conquer the villages like a castle?
