Carbonite Rush
this was the name used by historians to describe the era of history some 4,000 years before the Galactic Civil War, during which the Empress Teta System was tapped for its huge deposits of carbonite by the Mining Guild and other groups. It was said that there was so much carbonite to move that the Mining Guild couldn't hire enough freighters to move it along the Koros Trunk Line to Coruscant. Because the Koros Trunk Line provided the only safe hyperspace travel route from Empress Teta to Coruscant, it became known as the Carbonite Pipeline.
