Theories
- It is the Pala Ferry, an underground transportation network for the stations.
- It was the name of the intranet mentioned on the map
- Could be represented on the map by the blue windy channel that meanders around the The Swan, The Flame, and the ? (The Pearl)
- These three were the only stations accessible by the Conduit
