The Pipe[35.2, 82.9] is a pathway in Kezan that leads from Drudgetown to just near[26.0, 69.3] the First Bank of Kezan. It contains no mobs or NPCs, and seems to only serve as an alternative path.
On a side note, upon passing through the tunnel, on one side is a "window" showing the heart of a large factory. It appears to be an enormous engine with troll slaves busy laboring away inside.
- Patch 4.0.3a (2010-11-23): Added.
