The Great Hollow
The last stronghold of free Duergar, built in the stump of a tree the size of a small city. The few remaining clans of dark dwarves have been known to be kind to strangers found lost on their continent. Though no one actually knows; save for a few particular trusted individuals. Those who have been helped often find blank spots in their memory. The Duergar have become very skilled in clearing memories by alchemy. Magic is not a widely practiced art around them. Though there have been a fair share of shamans.
