The Game of Many Things
Migduar is a country composed mainly of mountains and valleys. It once contained the entire Faldur Mountain range that stretches from the edge of Carua all the way to the South Sea, but with the expansion of the Amber Waste, the southern half of the range was lost.
The weather in Migduar tends to change quickly and violently thanks to the mountains that make up half of the country. Roads through the mountains change yearly as the dwarves contend with landslides and fallen rocks, so reliable maps of the area are nearly impossible to make. Despite the navigational difficulties, though, trade caravans make regular trips to and from the mineral-rich mines in the mountains. Down in the foothills which are all that remain of Migduar's lowlands, traders come and go so frequently that the trade roads through the area are well-worn with wagon ruts.
Migduar is unique in that it has two capital cities. The foothills city Ban Faldur is considered Migduar's "Common Capital". The markets, guild houses, and merchants are all seated there. There is no magic school in Migduar, but you would be hard-pressed to find a better collection of craftsmen under which to apprentice. Meanwhile Dor Faldur, up in the mountains, is the "Deep Capital" of Migduar. There sits the Deep King and the heads of all dwarven houses, planning their recovery from their war with the drow.
South along the trade road is Bholam, a city that thrives entirely on trade. Very little is actually made there, but everything passes through. The merchants of Bholam are expert assayers, and it is safe to say that they have pretty much seen every trick in the book.
