West Vrassa is a sub-provincial district in the Kalistani province of Vrassa. Its capital is Bston. It is borded by Baltusia, Lodamun, Vrassa Proper, Kalistani Jahmaika, Funkistan, and Poppistan. Despite being one of the largest districts in Kalistan, it is sparsely populated. It is one of the highest areas of the Vrassan Plateau, and is lacking in arable land, though recent irrigation projects including a number of large dams have increased agricultural yields. Its western and northern borders are mountainous, home to the East Wall and Vrassan Mountains respectively, and draw much skiing tourism. The northern part of the province, known as the Harblop, in the Vrassan Mountains, is famous for its wine vinyards, which produce some of the best wine in Kalistan.
