The People's Republic of Duōmachāha, commonly known as Duōmachāha, or Duamacia in the Occident, is a sovereign state in Alshar. The country is comprised of the Duōma Plateau, a large plateau stretching from Kandara in the west to Metzetta in the east, and a lowland plain in the southwest north of Canpei and Rusana. The southern border of Duōmachāha is defined by various rivers for nearly its entire extent barring the Rusani Pass extending into the Pukhtun River Valley and the Snow Dragon Pass north of Tanhai. The northern border is similarly defined by long rivers pouring down from the two mountain ranges of the country, the Gates of Heaven (Tsosogidagungshō / སྒོཙོ།གི།དགུང་ཤཽ།), defining the north border between Duōmachāha and Kandara, and the Snow Dragon Peaks (R'tsesogiclōgonghas / རྩེ་མོ།གི།ཀླུ་གངས།) reaching from the Duōma Plateau to the Metzi coast. The rivers and mountains of the Duōma border make the country resistant to foreign influence, and this has proven so through history as Duōmachāha avoided colonization from Occidental nations and maintained a working relationship with Burgundie. Duōmachāha shares a tenuous northern border with Kloistan however where the Duōma Plateau gives way to the vast steppe land of northern Alshar. The majority of the state sits high above sea level, with 68% of the country consisting of the Duōma Plateau alone and 70% of the country's 2,599,416 square kilometers being highland. The country's capital sits on the plateau in Hronizha, while the largest city of Langsei resting on the shore of Lake Nongkun close to the border with Tanhai.
