Four domed cities, shielded and protected from the intense radiation and high gravity of Hades, were established in the Northern hemisphere, each at a confluence of rich mineral seams, each built into stable strata of rock, nestled into valleys and ravines. Each is home to an indentured working population of around 15,000, as well as the personnel required to maintain and service such a workforce. Each city houses up to 25,000 people in total in a single multileveled habitat, with large excavated spaces beneath housing industrial equipment.

Each city is nearly self sufficient, terraces of hydroponics bays powered by geothermal reactors feed the populations, all fully capable of maintaining their environment. With the nature of the Imperial presence on Hades the Directorate holds overall command, although the Solaris station falls under the jurisdiction of the navy. The central command and logistical facility is located in the main and northernmost city, christened Muspel. To date the new settlements have continued to increase production levels and supply to the naval yards has resulted in a far more reliable source of vital war materials. In the future many more settlements may be introduced to this harsh but newly tamed world.
