The Unquiet Earth
There are two Dwarven holds in the Tamed Lands: Bloodfist Keep to the west and Crackedspine Hold in the north.
The god, Drune, created the dwarves to assist with the outpouring from the Enclave Coup. The dwarves battled beside the elves until the fiends were beat into the gap between the mountains, and Drune rewarded them by placing gems and precious metals in the mountains for them.
Dwarves in the Tamed Lands tend to stay in their mountains, but there are individuals who seek their fortune elsewhere and decend into other parts of the Tamed Lands.
