Joak Drysso Joak Drysso was an officer in the Imperial Navy , and a staunch New Order loyalist — a squat , dangerous looking man whose hair and goatee turned gray early , and who hid his thoughts and worries behind a stern mask of command . Biography . From Endor to the loss of Coruscant . By the time of the Battle of Endor , Drysso was captain of the Star Destroyer " Virulence " , and his command was part of the fleet deployed against the Rebel Alliance in the battle above the Sanctuary Moon . When he saw the command ship " Executor " crash into the Death Star II , however , he realized that the Empire had lost the battle , and withdrew his own ship from the fight . From his perspective , striking back and achieving vengeance and ultimate victory was more important than fighting a losing battle . Subsequently , he became a supporter of Ysanne Isard , the Director of Imperial Intelligence , who he regarded as the rightful Empress , and also as the most capable of the surviving Imperial leaders . He supported her decision to cede Coruscant to the New Republic , and he was one of three Star Destroyer captains who joined her openly when she seized power at Thyferra . He was seen as a capable but not outstanding commander by well - informed observers in the New Republic , but Flirry Vorru considered him a " rising star " within the Empire , and he was appointed by Isard to command the Super Star Destroyer " Lusankya " , the embodiment of her power . The Bacta War . During the subsequent Bacta War , however , Drysso became disillusioned with Isard , musing that her obsession with Wedge Antilles and Rogue Squadron had blinded her to the wider response . He believed that Isard should have negotiated an alliance with other Imperial commanders and warlords , and that rather than concentrating on small targets like Halanit and Yag ' Dhul , " Lusankya " s massive firepower ought to have been employed to coerce the nominally Imperial governments of Corellia , Kuat and even neutral Sluis Van , so the massive shipyards of these three systems could thus have become a powerbase to build a new Imperial battlefleet . In Joak Drysso ' s view , Isard was a politician where a military leader was needed , and now that he had " Lusankya " he was starting to believe that he could be that man . Drysso correctly predicted that a raid on Yag ' Dhul Station would only expose Thyferra to a strike by Rogue Squadron , but he nevertheless carried out Isard ' s orders , only to be forced to flee when it seemed that Booster Terrik had armed the space station with hundreds of proton torpedo launchers . Sacrificing his former command , the " Virulence " , and the entirety of his TIE / LN starfighter complement , Drysso raced the Super Star Destroyer back to Thyferra at flank speed , in pursuit of Antilles and his allies . In the event , " Lusankya " arrived back in the system before the attackers , and when they appeared , Drysso discovered that not only had Sair Yonka and his Star Destroyer " Freedom " joined the Rogues , but Antilles and his allies had been able to equip a massive force of missile - armed freighters which could overpower the " Lusankya " s shields and savage her hull . Although Drysso never knew it , he had been driven away from Yag ' Dhul by nothing more than these missiles ' gimmicked and stripped - down targeting sensors . Battle of Thyferra . His opponents ' tactics in the subsequent Battle of Thyferra were designed specifically to take down the Super Star Destroyer with massive missile attacks , starfighters performing strafing runs against turbolaser emplacements , and smaller capital ships moving in for close - range attacks on vulnerable sections of the hull . Eventually , however , the attackers ' effective forces were reduced to a few starfighters and one obsolescent War Cruiser . Although " Lusankya " herself had sustained serious damage , and a final salvo from " Freedom " stripped her of her shields , Drysso scorned Isard ' s orders for him to flee the battle . He believed that he had won , and could now claim mastery of both Thyferra and the Super Star Destroyer . His crew were less certain , but the arrival of " Virulence " and the hundreds of TIEs she was carrying seemed to indicate that the battle really was over . However , the Star Destroyer was now under Terrik ' s command , and carrying New Republic starfighters . For the damaged " Lusankya " and her crew , the military and psychological impact of their attack proved devastating , but still Drysso refused to concede defeat . His mind appears to have become somewhat unhinged , and when Wedge Antilles asked him to surrender , he declared himself an Admiral ; then , when the Corellian dryly offered to recognize him as a Grand Admiral if he gave up the fight , he immediately adopted the rank , and attempted to set a collision course for Thyferra . At this point , he was shot by his adjutant , Lieutenant Waroen , who surrendered " Lusankya " to Rogue Leader .
