Kratas was a commander in the Imperial Navy serving as commanding officer of the Imperial I-class Star Destroyer Gorgon, which served under the command of Admiral Daala in the defense of the Maw Installation. Because of his position aboard Daala's flagship, he served as her second-in-command despite the fact two of commanding officers of two of the other Star Destroyers—Captain Brusc of the Manticore and Captain Mullinore of the Basilisk—out-ranked him. Loyal, determined, resourceful and competent, Kratas was perhaps the only person in Admiral Daala's whole command that she considered as a friend instead of merely a subordinate.
