The Sanctuary Pipeline was a hyperlane that was created around 3 to 4 ABY. The Pipeline was created by the Galactic Empire as a route to quickly transport supplies and materials to the construction site of the second Death Star. The hyperspace route ran from Sullust, which was located right on the Rimma Trade Route, to the Forest Moon of Endor, which was the site chosen to build the massive space station. It was located above the galactic plane, but below the Spar Trade Route that ran to Annaj and the Kuna worlds.
