Belka, officially the Principality of Belka (ベルカ公国), is a major country on the Osean continent. Belka shares borders with Osea, FATO, Gebet, Recta, and Ustio. Belka is best known for pioneering the use of aircraft in war, particularly with its legendary Belkan Air Force. The country has a massive industrial sector, which was utilized for a period of expansionism in the mid- to late-20th century. This culminated in the 1995 Belkan War, which led to severe losses in Belka as well as the only known use of nuclear weapons in Strangereal.
