Duergar Stronghold is one of the Dungeon Tile Sets.
Description[]
"The duergar build to last, and their strongholds are no exception. The Underdark is full of ancient, forgotten ruins of duergar cities, abandoned long ago in myriad battles against the drow, illithids, and other hostile denizens of the dark."
