Kingdom of the dwarves (or maybe just the range of mountain where they live) in the southern continent. They dwell in the clifftops (and deeper down) of the northern bank of the Corridor Sea. The cliffs are riddled with caves and tunnels, giving easy access to the surface. These surface caves are limestone and are separated from the deeper mines and dwarves that dwell there. These two groups of dwarves are strongly interconnected, but have separate roles in the community. They are slowly drifting apart, but still have strong clan ties.
The cliff dwellers are the ones that trade with the elves to the north and the humans across the sea. They mainly trade worked metal, gems, stonework and (cashmere?) wool for food stuffs to supplement their own sources. They tend herds of mountain goats to the north and trade with the elves and humans in the north for grains (mostly for beer and bread) and wood. They trade with the south for some of the more exotic food sources, spices, etc. The northern mouth of the corridor sea, where their main trade city is located, is an extremely busy port and you can find just about everything you’d need.
The deep dwarves tend to be paler than the surface dwarves. There are some food sources – fungus farms, underground fisheries – but they depend on the surface dwarves for variety in their diet. These are the miners and serious metalworkers and jewelcutters. The deep dwarves would be at the top of the caste system if one were to exist.
