The Harpers Ferry tunnel is a location in the Mire region of Appalachia.


A historic train tunnel near the town of Harpers Ferry in West Virginia, prior to the Great War the infrastructure was used to travel east across the mountains. Unbeknownst to the public, it was also the site of an underground pipeline project by the Bysshe Company.[1]

After the war, the tunnel was used by the Blue Ridge Caravan Company to transport goods and people into Appalachia. The Vault Dwellers are tasked with passing through strangler vines blocking passages in the Bysshe underground natural gas pipeline facility, utilizing strong herbicide previously developed by Bysshe.[2]

  1. Aries: "Just your run-of-the-mill illegal natural gas pipeline, courtesy of the fine people at the Bysshe Company. A bit before the War, Bysshe offered to maintain this historic train tunnel out of the goodness of their cold, corporate hearts. And, wouldn't you know it, they may have had an ulterior motive."
