Sareven

Sareven is a district in the Kalistani province of Vrassa. Its capital is the city of Tuask. It is located on the edge of the Vrassan Plateau, in the north and east are the Vrassan Mountains, in and around which the climate is very arid and large crops of opium are grown. Farther south is the more temperate valleys of the Vrassa and Neveras Rivers, where most of the population of the district lives. In the southern part of the district food staples like corn are more popular agriculture.

Sareven is located on the interior side of the so-called "Gates of Neveras," where the Neveras River passes through a gap between the Vrassan and Odufart Mountains from its higher valley on the Neveras Plateau to the coastal flood plain of Lower Neveras. Being at this bottleneck has made the district a historic crossroads, which is reflected today in the mix of languages and cultures, as well as in its bustling river, rail, and road throughways and its importance in industry.
