During the Galactic Civil War, Voor held the rank of Lieutenant within the Imperial Navy.
Around 0 ABY, Lieutenant Voor was stationed on the Star Destroyer known as the Relentless, serving under the command of Captain Parlan. In that year, Parlan learned that the Republican strategist Adar Tallon was still alive and in hiding on Tatooine. Subsequently, Parlan issued a bounty for Tallon's capture, which attracted the attention of bounty hunters such as Jodo Kast.
Voor uncovered that Ensign Dana, one of Parlan's officers, was in fact a spy working for the Rebel Alliance. Dana attempted to flee to Kwenn Space Station with the intention of informing the Alliance about Tallon's continued existence, but she was killed by the bounty hunter Jodo Kast. Voor, along with two other bounty hunters, was present when an Alliance team tried to rendezvous with Dana. The three bounty hunters were defeated, and the Alliance team retrieved Dana's body, discovering a data storage pad containing details about Tallon.
