Kingdom of Rhen
Always ruled by a set of twins (magicly assured) and helped by their princes and princesses consort. Keeping 2-4 people at the top of the pile has limited the ego issues that can come with having monarchs. A house of lords (feudal organizational style advisors) from the various dutchies around the kingdom has varied in power over the generations since it's creation. But the magic that protects the kingdom from hostile neighbors is keyed to the royal family and is part of the magic that assures twins in every generation. So where a traditional monarchy would have more cause to worry about them taking over, the populous wouldn't stand for it and attempted rebellions in the past have ended very badly for the would-be monarchs. However the same defenses that make the kingdom nearly unassailable have also fixed the borders and Rhen's own attempts in the past to try it's hand at imperial expansion have also ended very badly.

The City-state regions are Rhen, Hahn, Bakkarholt, and Anicium. Before the Khans they had a long history of conflicts with each other. Bakkarholt was always considered the richest and best defended, though it is also the smallest by population. Rhen was always the most balanced which led to it's coming out on top in the end. Hahn is known for it's cavalry, to the point that the city itself never built walls. Anicium suffered the worst under the Khans and has not really recovered. (it also needs more development -Alex)
Rhen as a county is known for the variety of its farm produce and pasta. Combining the two in endless variation. Having a larger population than Bakkarholt and coming out of the Khanate years in better condition than Anicium it has also taken over much of the production in the central region and has the largest center of gnomish inventors in Eolanara.
