The Corellian Cell
The moon of Gus Tranchon is the closest and smallest of three moons in orbit around the planet Corellia. The moon was once very rich in metals and rare minerals and was mined, the resources provided giving Corellian Engineering Corporation its initial boost and helping it to grow into one of the largest corporations in the Galaxy.
Now the moon has been completely hollowed out and is a warren of shipyards, R&D labs, offices and production facilities. Although CEC maintains an office building in Coronet for its top executives, most of the actual work is carried out on Gus Tranchon.
