Skopje

Skopje was a UNSC Inner colony home to several million people. The colony was around during the Human-Covenant War and was glassed in 2547 following a large battle. The planet had highly developed urban areas, roads, and railways sprawled across island continents. The planet was also home to the headquarters of a shipbuilding corporation. Orbital Drop Shock Troopers were called in to defend the headquarters during the evacuation of their shipyards, under the justification that the machines, tools, and personnel that could be saved would be relocated to Reach to continue building parts for the war effort. A wealthy CEO built a castle in the colony, which would later prove valuable during the battle.
