A Communications Officer was employed by the Galactic Empire at the Kuat shipyards throughout the Galactic Civil War. He found himself at the shipyards when the Space Battle at Kuat took place in 0 BBY. As Rebel corvettes decimated the shipyards, he urgently tried to reach the Star Destroyer Tyranny. The Tyranny was normally based at the shipyards, but had been reassigned to Fresia to defend against an anticipated Rebel attack aimed at seizing fighter prototypes. The ship's commander ignored his calls until the communications officer initiated Emergency Code Zero, compelling the Tyranny's immediate return to Kuat.
