Operation : Thunderstroke Operation : Thunderstroke was the code name for a mission sanctioned by Imperial Regent Morlish Veed that involved ambushing a secret meeting scheduled between exiled Galactic Emperor Roan Fel and members of the Jedi Order . Led by Moffs Rulf Yage and Fehlaaur ' aitel ' loro aboard the " War Hammer " , the Imperials ' primary objective was to capture Fel , so that he might stand trial and be sentenced to execution , effectively ending the resistance movement of his exiled forces . The operation was planned to be carried out by the First Sith Imperial Strikeforce , a unit of the Imperial Navy formed by members of the One Sith , who would lead Skull Squadron from their " Fury " - class starfighters . The strikeforce failed to complete its prime objective , as Emperor Fel eluded capture . However , the Sith were successful in capturing Princess Marasiah Fel . Prelude . When the rumors of Darth Krayt ' s death reached to the remnants of the Jedi Council , the surviving Jedi decided to join the fight alongside the newly formed coalition between Fel ' s resistance and the surviving Galactic Alliance forces led by Gar Stazi . Agamar , an agricultural world on the edge of the Fel - controlled space , was selected to be the location of the meeting . Through the Sith , intel of this rendezvous reached Imperial Regent Veed , who planned an attack in order to capture Roan Fel and his daughter so the deposed monarch would undergo public trial an execution . Veed hoped that by eliminating Fel , his Empire - in - exile would inevitably crumble . Veed named the operation " Operation : Thunderstroke " and ordered Moffs Yage and Fehlaaur to oversee it and command the First Sith Imperial Strikeforce , a Navy unit composed by pilots of the One Sith . Yage himself , however , resented having to lead what he considered " monsters " . Under the protection of his Imperial Knight s , Fel landed on Agamar to await the Jedi delegation , which was composed by Jedi Masters K ' Kruhk , also a member of the Jedi Council , Rasi Tuum and Hira , as well as Jedi Knight Shado Vao . Both parties dressed in the manner of Agamar ' s farmers to prevent recognition , though the Imperials were already en route . The Jedi agreed to cooperate with Emperor Fel and Admiral Gar Stazi and coordinate their attack with them . In retribution , both Bastion and Stazi ' s forces would give safe haven to the Jedi . Moff Nyna Calixte arrived to Agamar to warn the allies , landing her starfighter at a distant farm so as not to alarm either party . Paying a native farmer to hide her vessel , Calixte proceeded to the meeting aboard a borrowed Agamarian beast , disguised in the farmer ' s cloak and hat . The Imperial Knights sensed Calixte approaching and opened fire against her , having considered her a threat . Emperor Fel recognized her and ordered the shooting to stop . Surrounded by lightsabers , Calixte warned both parties that the Sith knew of the meeting and would be arriving at any moment to hunt down Emperor Fel . At that precise moment , the Sith forces , led by Yage ' s " Pellaeon " - class Star Destroyer , the " War Hammer " , emerged from hyperspace and engaged Fel ' s own Star Destroyer , the " Dauntless " . The operation . The " War Hammer " deployed its squadrons of Sith - Imperial starfighter s and Sith Furies to attack the " Dauntless " as well as the delegations on the planet ' s surface . Aboard the " Dauntless " , Admiral Tohri Challon ordered her crew and pilots to attack the Sith Imperial forces in order to buy time for Emperor Fel to escape . As the space battle progressed , several of the Fel loyalist pilots ejected from their damaged Predator starfighters to save their lives . However , Darth Rauder , the Sith Lady in command of the strikeforce pilots , ordered Captain Gunn Yage to eliminate them as well . When Yage refused to follow Lady Rauder ' s orders , the Sith threatened to kill her with the Force if she did not comply . Rauder employed her telekinetic abilities to exert pressure within Yage ' s head , causing her to bleed from nose and eyes . However , to save Yage ' s life , Lieutenant Tev Rimon fired at the pilot , much to the anger of Lady Rauder , who wanted Yage to personally shoot at the enemy pilots and threatened to kill Rimon if he defied her orders again . As Emperor Fel prepared to escape , the delegations were attacked by a group of several Sith , amongst them a Dashade , a Zabrak , and a Devaronian . The Jedi and the Imperial Knights fought side by side to protect Emperor Fel so he could reach his shuttle , the " Defender One " , killing some of the attacking Sith in the process . However , Master Hira perished when a Nautolan Sith struck her with Force lightning . Fel reached his shuttle alongside Masters Antares Draco and Treis Sinde while Princess Marasiah Fel , Imperial Knight Azlyn Rae and Master Rasi Tuum held off the enemy . Before the three could enter the shuttle , however , a number of enemy fighters approached . Though Master Draco desired to rescue the Princess , Master Sinde reminded him that the Emperor ' s safety was his priority and that they had to get off the planet . As Fel , Rae and Rasi Tuum were overwhelmed by the enemy fire , Draco ordered the shuttle ' s pilot to evacuate . In space , the " War Hammer " had inflicted heavy damage to the " Dauntless " , whose shields had already failed . However , Admiral Tohri Challon ordered her crew to keep on fighting until the Emperor ' s shuttle had made the jump to hyperspace . The shuttle successfully escaped but the " Dauntless " was destroyed . Admiral Challon , her second in command , Captain Basile , and the entire crew of the Star Destroyer perished . Aftermath . Though the main objective of the operation was not achieved , the battle was not a defeat for the Sith Empire . The " War Hammer " managed to destroy the " Dauntless " , depriving Fel ' s fleet of a valuable starship as well as a loyal Admiral , while the Sith sent to the planet succeeded in achieving the mission ' s second objective : the capture of Princess Marasiah Fel . Alongside Princess Sia , Azlyn Rae and her former Master , Rasi Tuum , were captured as well . Emperor Fel managed to escape to hyperspace alongside Antares Draco and Treis Sinde , thanks to the efforts of his Knights and particularly the deaths of Admiral Challon and her crew . Once safe in hyperspace , Fel saluted the noble sacrifice of his soldiers , which he had witnessed as the " Defender One " flew above the " War Hammer " . The Force also allowed Fel to sense that his daughter had survived the attack and that she was in custody of the Sith . He ordered Master Draco to save her , a task Draco swore to complete . It was later revealed that the one who betrayed Fel to the Sith was Hogrum Chalk , the Emperor ' s brother - in - law and the Imperial Knights ' master armorer .
