Dwarves

One dwarven kingdom on the continent of Kavarn is Dukarth.
For clothing, dwarves tend to favor wool and leather, often with brass buttons and silver thread.
Some dwarven enclaves and holy places are guarded by the spirits of their ancestors. These sometimes inhabit golems, which gives them a way to interact more directly.
Dwarves are known for holding grudges. In particular, if they are killed when defending a holding, it's relatively common for them to rise as undead in response. Dwarves are often entombed in full battle regalia and the surest way to get them to rise is to try robbing these tombs.
