Hundruð Mine
Hundruð Mine sits in the Iron Mountain and is the largest mine in the world and is the mine that the Dwarves draw from the most. With two entrances with large dwarven statues guarding them the mines span for hundreds of thousands of miles. The mine also serves as the passage between mountains for the dwarves. without it Clans Bronloch and Torc would be completely cut off from the rest of the dwarves. However this mine while vital is extremely deadly. It has grown so much that without a map to the mine you are destined to get lost. Clan Gigan are the only ones who have figured out how to navigate the mine well enough to make maps. If one was to try and go through Hundruð Mine without a map, well, they would never see the light of day again.
