Firmus Piett, a human male native to Axxila, was an Imperial officer who served in the naval forces of the Galactic Empire during the Galactic Civil War. At the time of the Battle of Hoth, he served as first officer of the Star Dreadnought Executor—flagship of the Sith Lord Darth Vader—assisting Admiral Kendal Ozzel. After Ozzel committed a fatal mistake during the hunt for the Rebel Alliance, Piett was promoted to admiral and given command of Vader’s flagship. Piett served in that capacity until the Battle of Endor, where he served as a Fleet Admiral, when the Imperial Navy confronted the Rebel Fleet around the second Death Star battle station in the year 4 ABY. The admiral perished aboard his starship when Arvel Crynyd‘s A-wing starfighter crashed into the Executor‘s bridge.
