The city is located in the innermost major belt, mb 1, and overlooks the Horologium and the fortress built by Tetragnostica during the Interim to conduct her research on the Eye safely. This means that the skies are usually cloudy, and that the city receives more light than any other settlement.
Unlike Kunanoten, Nea Trestua, and Survaní Doisseia which were carefully planned with above-ground mass transit, the majority of Chelvaní Doisseia's mass transit was carried out by a vast subway network (part of the Doisseia River Transit Navigation Service) servicing nearly every major intersection within the contingent city. Even more uniquely, it continued to grow and to be used (although in different ways) following the Shattering (retronymed now as the Dis Rapid Transit Network Service); the system sprawled immensely, and incorporated the main ring of a disused supercollider in the process. Wanisin slave traders were known to operate in some of the disused parts of the "Dart" subway network during the time of the Regení Mitraje.
