Short, stocky, stubborn, and hairy. These folk are known for their engineering marvels and love of minerals, rock, and stone. (These are your traditional Dwarves in fantasy.)
There are 3 general groups: First, those merchants, traders, outcasts trapped outside the massive holds of yore when The Great Rending struck the word. They created diaspora communities in villages and cities of humans.
The second group are those who stayed within the mountains and hills, hiding, fighting, and dying for every inch of their remaining territory against the hordes of darkness from within the earth.
Lastly, there are those who retreated out from the mountains and halls into the overland, generally viewed as cowards and traitors by the second group.
