Mongolia is a large, completely land-locked country between China and Russia. Very few people live here, the density is the least worldwide (besides Greenland or Antarctica). In fact there is only one significant city: Ulaanbaatar (formerly Ulan Bator). It is best known for Djengish Khan who conquered the world and made China build the Great Wall as protection. There is a lot of space, many horses, camels, falcons and yurts. It can be really cold here.
