Bachenkall, a male Human Imperial Navy officer, was one of the Star Dreadnought Executor's helmsmen during the events leading up to the Battle of Hoth. He was trained in capital ship piloting and tactics at the Imperial Training Academy on Raithal, and he eventually rose to the rank of warrant officer. In 3 ABY, Bachenkall was present in the crewpits of the Executor, serving under Lieutenant Commander Ardan, when Darth Vader entered the bridge to discuss the findings of a Viper probe droid. The droid had discovered the location of Echo Base, the Rebel Alliance's headquarters in the Hoth system.
