The Dwarven Lands
Traditional Dwarves typically live in clans of 800-1500 people, scattered throughout the Covenant in areas often considered uninhabitable by less stout races. Because the other races see little value in mountain land, the dwarves are mostly free to do as they please and to sort out territorial claims amongst themselves, especially as long as they keep providing such fine quality goods to the cities.
Occasionally, and much more recently in the past few decades, non-dwarves will purchase mining rights. In some areas, it is rare to see a dwarf in the mines, as Nesshin labor is much cheaper than Dwarven labor. The more prosperous dwarven clans rarely mine anymore, much to the protest of the dwarven elders.
