The city was separated into a number of districts, depending on the purpose of the buildings inside. The largest district by far was the first two housing districts, taking up almost three-fifths of the city. Then came district three, the commercial district, and district four, the shipping district, where one could find both the docks and the entry point for trade into the city. Then came district Six. District six was a fortified section of the city that had, apparently, once been a large military barracks, a fort within the city. Built against the inner city walls, it was where the military had long been housed, prior to the expansion of the city in Artorius's grandfather's time, which had seen the outer city walls' construction, as well as two more modern and better-positioned forts that, while smaller individually, allowed the city's military to increase to half again its original number.
