Captain Kallic of the Imperial Navy briefly served as the temporary commander of the Super Star Destroyer Executor, the personal flagship of the Dark Lord Darth Vader, in the aftermath of the Battle of Hoth during the Galactic Civil War. Substituting for Admiral Firmus Piett, Kallic oversaw the Executor's return to Coruscant so that Vader could report his encounter with Luke Skywalker on Bespin's Cloud City to Emperor Palpatine.
