As the Lower Riewaye peoples population recovered from the civilization-shattering and culture-crushing effects of the Red Death, an egalitarian, democratic, and non-hierarchical society formed in the place of the Riewaye Confederation that had come before. The increasing population eventually found it more worthwhile to spread to lands on the riverside abandoned during the apocalypse, resettling these regions and making them Riewaye again. The locals were either completely culturally different people from the steppes which had moved in when the Riewaye fled... or didn't exist altogether, and either way the society of the Lower Riewaye easily integrated these peoples through marriage so that, within a few generations, there was effectively no difference between them and the rest of the Lower Riewaye peoples who had settled the region. As expeditions and bands of settlers were prepared to go and found new hamlets and farms along the riverside, where once sprawling trading towns had sat, in the north a very different sort of expansion was occurring.

The Upper Riewaye people, after their settlement in the north, very quickly became a rather violent people. A slave-based economy that supported a ruling class of warrior and engineer chiefs was, and after only a few generations it became clear that this economy was here to stay. The Upper Riewaye, for all their technological advancements, were not a nice people. Raids for slaves and control over ore deposits were nearly constant, and eventually some entire tribes had to be forced out. Several of which were forced into the desert to the east, after being evicted from the copper-rich lands that they had stayed on. These tribes settled to the east, in the flat, dry deserts, and made do. To the west, across the Droga River, a similar ordeal happened, where several villages of people living on tin deposits were forced to flee west into the drier steppe. Luckily the introduction of horses and their riding occurred very soon after, and these people did not perish as might have been expected by other Riewaye people in any other time of history. Further south several regions along the river were settled in an organized manner by Upper Riewaye chiefdoms in order to enslave the locals establish more living space for Upper Riewaye people to farm and build their newly invented machines for irrigation and food production.

For the first time in centuries, the population of the Riewaye cultures had recovered to the point where organized settlement (and unorganized settlement) occurs.
