Hoffnung

The geography around Hoffnung features rolling hills and two major rivers. One flowing out of Ustio. The other one flowing out from another country; possibly Recta. The same rolling hills might also be the foothills of the mountain range that makes up the 'Round Table'. The only evidence of geology that is visible is that the area is possible made up sedimentary rocks that have been compressed slightly to form the foothills. Hoffnung has become Belka's leading producer of military supplies.

The Belkan War - Operation Cannibal
One of Belka's main Idustrial centers, other than Sudentor, the industrial city was burned to the ground by a combanation of Osean Saturation bombing and internal sabatoge on the part of Belka on June 1st.

The operation started out as a precision bombing mission, only meant to destroy Belkan Factories and Military Facilities, but quickly evolved into a brutal Saturation bombing. As more and more of the city was destroyed by Allied Bombers and Tomahawk Cruise Missiles, the Belkan Military received orders to pull out from Hoffnung, but destroy any facilities the Allied Forces could possibly use. Even as the Belkan Military’s scorched earth campaign began, Allied Bombing continued. The Belkan Air Force arrived over the city and engaged the allied bombers and their escorts. The bombers were destroyed, but the Allied escorts managed to destroy the BAF Fighters and secure the city.
