Delak Krennel Delak Krennel was a Human male who served as an Imperial admiral - turned - warlord in the years following Emperor Palpatine ' s death . Krennel was a muscular male Human with a cybernetic replacement from the elbow down on his right arm to replace a loss during battle with another Imperial warlord ' s forces . The replacement glowed red when Krennel would use it in a way that would normally require muscle use , a feature that instilled fear in his subordinates . Biography . Krennel was born on Corulag . At a young age , he demonstrated the firm Humanocentrism as well as the sadism and penchant for brutality that would mark his later career when he helped his father burn down alien - owned farmlands so they could be seized by a Human agro - combine . He began his Imperial service when he joined the Prefsbelt IV Naval Academy . His academy record was relatively undistinguished , except for several prizes as an intramural unarmed combat champion ( in later years , Krennel still kept himself in fighting trim , and his abilities were only enhanced by his mechanical arm ) . Upon graduation , Krennel rose through the ranks and was eventually assigned to Thrawn ' s Unknown Regions armada , as a captain in command of the " Reckoning " . However , the assignment was in actuality exile imposed by his then - commanding officer , Grand Admiral Rufaan Tigellinus ( who also had Thrawn exiled largely for his Chiss heritage ) , due to Krennel ' s brutality being extreme even for the Empire . Krennel resented serving beneath a nonhuman officer , as well as his post at the Unknown Regions , but could not voice his frustrations to Thrawn , so he instead used his rage to escalate his brutal nature on the alien prisoners . Eventually , Krennel ' s anger towards Thrawn had him decide to use a Vibropike against one of Thrawn ' s artworks , in mockery of his superior ' s tendency to utilize alien artwork to exploit an alien race ' s weakness during battle . This resulted in Thrawn ordering one of his Noghri Death Commandos to cut his arm off from the elbow down before he could damage it , leading to his gaining a prosthetic afterwards . This event gave him a new respect and fear of Thrawn , proceeding to rise to the rank of Admiral . Eventually , he chose to disobey an order to subjugate a world . Instead , Krennel chose to pacify it via bombardment , a choice that saw him recalled to Coruscant for a personal punishment from Palpatine . Before Palpatine could deliver his judgment , he perished at Endor . In the chaos that followed , Krennel fled the fleet and styled himself as a warlord , with the title of " Prince - Admiral " , in the ensuing Imperial Civil War . Early in the conflict , Krennel aligned with General Paltr Carvin , but accepted orders from the burgeoning authority of Ysanne Isard . On Isard ' s orders , Krennel attempted to capture Leia Organa on Axxila , but was stopped by an AT3 Directive issued by Soontir Fel at the behest of Sate Pestage . The interruption irked Krennel , causing him to offer his allegiance directly to Isard in exchange for aid in retrieving Pestage on Ciutric IV . When Pestage escaped the New Republic , he sought asylum with Krennel , unaware of his hatred for the Grand Vizier . Krennel strangled Pestage and seized his holdings in the Ciutric Hegemony , before coldly murdering Pestage ' s entire family . During Thrawn ' s campaign , Krennel offered monetary support and pretended to pay heed to his former commander ' s call for unity . After the defeat of Thrawn at Bilbringi , Krennel was targeted to be an example to warlords of the New Republic ' s newly strengthened policy against them . With the clone Isard , Krennel began a plot to sow chaos in the New Republic between Human and nonhuman species , waylay freight traffic to Coruscant at Liinade III , and conquer Coruscant . Rogue Squadron put their plans to a quick end , with the aid of the original Ysanne Isard . Wedge Antilles forwarded intelligence provided by Isard to the New Republic Defense Fleet , which dispatched a flotilla to Ciutric before Krennel ' s forces could launch their attack . The flotilla , under the command of Admiral Gial Ackbar crushed Krennel ' s forces in a Thrawn Pincer and seized the shield - stripped capital of the Hegemony . Krennel died aboard his flagship , " Reckoning " , when a concussion missile launched from either the " Selonian Fire " or " Corusca Fire " struck the forward viewport , shatter the viewport and sending shards through Krennel . When it exploded , Krennel and the entire bridge were destroyed . Personality and traits . Krennel was a competent tactician and strategist ( as evidenced by his promotion to Imperial Admiral ) , but he was a brutal man by nature and had little tolerance for the subtler approaches espoused by two of his old superiors , Thrawn and Isard . His reflexive response to any obstacle was to crush it . He was very sadistic , as well as masochistic , the latter trait being adopted shortly after he lost his arm to Thrawn when trying to damage one of his artworks . During his brief tutelage by Isard ' s clone as ruler of the Citruic Hegemony , he began to experiment with political propaganda and other means of manipulating opinion in his favor , presenting himself as a sympathetic ruler rather than a tyrant . He started to see the effectiveness of these methods and flattered himself that he was a quick learner and would soon be able to master them without " Isard ' s " help . His death in battle cut short any promise he might have shown .
