Tar Morden, a world situated along the Corellian Trade Spine within the Expansion Region, was classified as a planet. A Techno Union manufacturing plant was present there. As the Clone Wars concluded, the Galactic Republic took control of the facility and obtained a large number of crab droids, subsequently shipping them to Carida.
Subsequently, the planet became the location for a Rebel production facility for starfighter construction. Imperial Intelligence gathered data concerning this operation. This data was transmitted to Intelligence Sector HQ via a Plexus Droid Vessel. The Rebels managed to intercept this vessel, which then initiated self-destruction, launching its I2-CG droid into space, eventually crash-landing on Goratak III.
