Ambush on an Imperial construction module

In 3 BBY, the crew of the Ghost was ambushed by the Galactic Empire in an Imperial construction module that orbited Geonosis. The rebels boarded the construction module while investigation intelligence reports from the rebellion that the Empire had been constructing something over Geonosis. Unknown to the rebels, this was the Death Star, an armored battle station capable of destroying entire planets, which had already been moved. When the rebels boarded one of the construction modules, they were quickly attacked by Agent Kallus of the Imperial Security Bureau and several stormtroopers. The rebels fought their way back to the Ghost, but one of the rebels, Garazeb Orrelios, remained locked in single combat with Agent Kallus. The Ghost departed while Orrelios headed for an escape pod, but he was followed by Kallus, who also boarded the departing pod.

The Ghost and Imperial forces engaged in a firefight outside of the module, which damaged the escape pod and sent it crashing onto Bahryn, an icy moon of Geonosis. Orrelios and Kallus were forced to work together in order to survive. In the process, they learned more about one another's pasts and motivations, and Kallus began to recognize the cold realities of serving in the Empire.
