North Osea

North Osea was a postwar federal state of the Osean Federation formed after the Belkan War in June 1995. The region, formerly the southern half of Belka, was assimilated by Osea as compensation for war damages as part of the Treaty of Lumen, causing the Belkan Federation to dissolve. A decade after the war, former Belkans living in the area disregarded the Osean ownership, continuing to believe that it righteously belonged to their country.

Heierlark AFB, a Belkan airbase that became property of the Osean Army, was built somewhere in North Osea.
