Caer Darkstone

From the introduction:
The dwarves of Darkstone have had a long, if somewhat checkered history. The halls of Darkstone are ancient and one of the oldest dwarven caers in the world. They have since the beginning mined the dark marbles of the mountain, and unearth the silver mithreal of its deep mines. The riches of the mines has played a strong role in the hall’s history, but even more is the pride and honor of these brown dwarves which has governed their actions and affairs with the rest of the northlands.
