Mithral Hall

Mithral Hall is the fabled anscestral home of Bruenor Battlehammer, along with Clan Battlehammer. The prosperous dwarven mine has tunnels that are often lined with natural veins of mithral as thick as an arm.

Tunnels
Mithral Hall has tunnels in the Upper Underdark that connect it to Citadel Felbarr.

History
After the hall was reclaimed from duergar and a shadow dragon, the dwarves of Clan Battlehammer moved from Icewind Dale back to their ancestral home with dwarves from other strongholds immigrating there as well. Bruenor later became the eighth and tenth king, after his ancestor, Gandalug, first and ninth king, was recrowned and subsequently died.
