Dwardrun Passage

The Dwardrun Passage is the southernmost passageway leading out of the Great Cavern of Aman-ya. It leads to tunnels which link the dwarven Dwergenlaw of Deephold to the territorially unclaimed but culturally firmly dwarven region known as the Dwarven Forelands.
The passage has many small mines and tunnels branching off from it which were dug by the Dwarves over millenia.
