Trachta Trachta was a Human male Imperial Grand Moff over the Imperial Center Oversector who unsuccessfully masterminded the Anti - Sith conspiracy and attempted to kill Emperor Palpatine and Darth Vader during the Galactic Civil War . Trachta appeared to be a Human male , but was encased with cybernetic implants after being horribly maimed by a thermal detonator during the Clone Wars at the hand of a Jedi Padawan defecting to the Confederacy of Independent Systems . His most distinctive feature was a triangular breath mask that fed into the mechanical lungs required to keep him alive and obscured his pale face . In addition to his cybernetic respiratory system , Trachta ' s organic eyes were replaced with ocular cameras , and a third ocular camera was installed in the back of his head , allowing him to see behind him . Biography . Early political career . Trachta first met Senator Palpatine during the last years of the Republic . He was impressed by a lecture given at the Republic University and offered his services to Palpatine if ever they were needed . Palpatine forwarded Trachta ' s records to the Republic Military Academy , where Trachta became an instructor in tactics and intelligence . In the first days of the Clone Wars , Agent Trachta coordinated the transfer of Tark Squad from Kamino to the " Golandras " in the Marat system . This squad was actually a team of clones from the Dark Worlds , the Empire of Zeta Magnus . Designed to infiltrate the Grand Army of the Republic , the clones were eventually destroyed by Jedi Halagad Ventor during the Battle of Skye . Serving as liaison between the Jedi High Council and Armand Isard at the Senate Bureau of Intelligence , Trachta was personally assigned by Chancellor Palpatine to investigate and capture Jedi leaving the Republic for the side of Count Dooku . On one mission to the planet of Noctralis they tracked a Padawan who had joined Dooku . Trachta and a team of clone troopers surrounded the Padawan , but he armed a thermal detonator and used the Force to throw it at Trachta and his men . The clones were incinerated , as were Trachta ' s arms and eyes . He was brought back to Coruscant , where his arms and eyes were replaced with cybernetics , as well as his damaged respiratory system . Trachta resumed his service by the end of the Clone Wars . Trachta , as a loyal servant of Palpatine , became one of the first Moffs in the Galactic Empire , where he ruled over the Imperial Center Oversector . He served as the commander of the 1st Sector Army during the Clone Wars . Trachta held an intense rivalry with the Supreme Commander of the Imperial Military and Sith Lord Darth Vader . The Gentis coup . Shortly after the creation of the New Order , Trachta was forced to work alongside Darth Vader and Lieutenant Laurita Tohm . Palpatine was severely injured from a terrorist attack shortly after the graduation of various Imperial cadets , organized by Headmaster Gentis as part of a military coup against the Emperor . Like Vader , Trachta survived the airborne viral attack because of his breathing apparatus . When Vader and Tohm encountered him near the weakened Emperor , they immediately accused him of being involved in the coup , but Trachta vehemently denied any involvement . The trio sought a refuge for the Emperor where no one could find him , and Vader realized that only one such place existed — the secret Jedi prison known as the Prism . While Vader and Tohm went to the Jedi Temple to find the location of the Prism , Trachta remained with the Emperor in a secret shuttle hangar , and fought off a medical droid re - programmed to kill Imperial officers . The Ghost Prison . On the journey to the Diab system , Trachta recounted the origin of his injuries to Tohm , and in return , learned how the young lieutenant had been disfigured . After landing at the Prism , Trachta and Tohm destroyed the droid guards while Vader slew the lone Jedi warden . After reviewing the prison records with Vader and Tohm , Trachta discovered that the rogue Jedi who had caused his injuries was imprisoned within the facility . Trachta and Tohm found the fallen Jedi ' s cell within the prison and Trachta told Tohm to seal the cell behind him , as he would not be leaving for many hours . He then began to savagely beat the Jedi with his cybernetic fists , exacting bloody revenge . Vader amended Tohm ' s idea , and rather than simply releasing the prisoners , he forced 207 of them to fight one another , as well as Tohm and himself , for the right to serve the Empire . The battle was vicious and wild , with casualties mounting quickly . In the end , only thirty - three prisoners survived in fighting condition , and Vader ordered Trachta to tell the survivors what it meant to serve the Empire . He told the survivors that their crimes were now forgotten , but their reasons for committing them were not — they would now serve an institution not beholden to the " selfish " senators of the Republic , nor the Jedi Order . The prisoners knelt before Trachta and the others , becoming Imperials through their submission . He then told them that their training was to begin that night . Afterward , Tohm entered a room where Trachta was undergoing a diagnosis from a medical droid , carrying a bloodied length of pipe . As Tohm vomited , disgusted by the act he had committed , Trachta recognized that the young man had done a task for Vader — beating a wounded prisoner to death . Trachta then urged Tohm to consider following him instead of Vader , claiming that the Sith Lord only knew how to make followers , whereas Trachta could train Tohm to be a leader . Ending the coup . Tohm realized they could use Shonn Volta , one of the prisoners and a hyperspace expert , to find Grand Moff Wilhuff Tarkin while he changed hyperspace lanes at the nexus of several trade routes . Successfully finding and hailing his vessel , the Imperials and freed prisoners secreted themselves within Tarkin ' s shuttle . When the shuttle landed and Gentis attempted to take the Grand Moff prisoner , Trachta , Vader , and the others attacked . Though Gentis ' s forces outnumbered the attackers by eight to one , there was no accounting for the disparate skills Vader ' s group brought to the fight . Trachta ' s onboard targeting computer allowed him to use two blasters , while Vader used the Force to slaughter dozens of cadets and Volta used her sniper skills to kill a detonations expert , igniting his grenades and further decimating Gentis ' s forces . Soon , Gentis ' s own son , Caul , was killed by Tohm , and Gentis stopped fighting , cradling his fallen son in his arms . The Emperor himself , recovered from his ailments , attacked and killed Gentis with Force lightning , leaving him a charred husk . In the aftermath of the battle , the Emperor rewarded Trachta for saving his life by promoting him to Grand Moff as well as Headmaster of the Imperial Academies . Unbeknownst to him , the surviving ex - prisoners , who were celebrating their victory and impending reward with the Imperials that they had fought beside , were at that moment trying to determine their fates . Trachta believed that they owed the prisoners a debt of gratitude , and that they should honor their promises to them . Vader thought that they should all be executed , to prevent them from becoming enemies in the future . Tohm created a third option , and the prisoners were told they would be set free but they had to exile themselves to the Corporate Sector . Before they left , they were met by Trachta , Tohm , and Vader , and the details of their release were once more gone over . Nax Cirvan agreed to all of the parts of the deal , and Trachta wished him luck . As the ship ascended over the Coruscant cityscape , it detonated , killing Cirvan and all those aboard . Tohm and Vader had betrayed the agreement , as well as Trachta , who was horrified by the dishonorable massacre . He railed against Tohm and Vader for their duplicity , but both men were unapologetic . Trachta , disgusted , left Tohm to Vader ' s care , no longer willing to try to take the young man under his own wing . Tohm ' s betrayal of Trachta ' s trust would be his undoing — after the Emperor promoted Tohm to the rank of Admiral , Vader murdered him , not willing to suffer a future rival . Anti - Sith conspiracy . In 11 BBY , several years after the birth of the Galactic Empire , Trachta became increasingly more power hungry , craving to overthrow the Order of the Sith Lords and take control of the Imperial state . Just as Gentis had done before him , he concentrated his life on the upcoming coup , preparing to assassinate the Sith and rule the Empire . Trachta was not the only member of the conspiracy , but he recruited the other conspirators as well , including Grand Moff Bartam , General Skosef , Second Officer Dezsetes and the assassin Gauer . He saw both the Jedi and the Sith as foolish , declaring that the Empire could not be ruled by a clique of two Force - sensitive men . Trachta convinced his accomplices that the Empire was doomed unless the conspirators would overthrow the theocratic Sith and install a secular leadership . The pivotal element in Trachta ' s plot was a detachment of a one hundred clone stormtroopers , programmed loyal to the conspirators and trained by an army officer named Carsan . In 1 BBY , Trachta accompanied with Darth Vader and Moff Kadir , commander of the Coruscant Security Force , to test the blaster accuracy of the stormtroopers . Vader ordered the stormtroopers to be transferred to Grand Moff Wilhuff Tarkin ' s ship , but Kadir objected to the Dark Lord ' s orders , because the stormtroopers were assigned to be in the Coruscant City Guard . However , Kadir finally had to obey Vader unless he wanted to be executed like his predecessor in the Coruscant Security Force . Sensing Kadir ' s hatred of the Sith , Trachta recruited the Moff to the conspiracy . Then , Trachta visited in the Imperial Palace and met Emperor Palpatine , who informed Trachta on his plans to dissolve the Imperial Senate . Afterwards , Trachta met Carsan and the clone stormtroopers . Trachta ordered Carsan to be placed under arrest to prove the stormtroopers ' loyalty to him . When Carsan panicked and tried to resist the arrest , he was shot down by the stormtroopers . In the meeting with the conspirators , Trachta introduced Moff Kadir and announced the Emperor ' s scheme on rendering the Senate irrelevant . Using the fact that Vader was sent to Dargulli to slay a lightsaber - wielding Force - sensitive , Trachta planned to storm the Imperial Palace with the clone stormtroopers and eliminate the Emperor during Vader ' s absence . Meanwhile , Dezsetes was assigned to eliminate Vader aboard the " Imperial " - class Star Destroyer " Mathayus " . However , Trachta became paranoid , suspecting Bartam for being disloyal and secretive . He asked Kadir to observe the Grand Moff , sowing the seeds of distrust and rivalry between the conspirators . Trachta planned to assassinate Palpatine by destroying his personal " Lambda " - class shuttle , as the Emperor was going to visit the unfinished Death Star . Trachta ' s clone stormtroopers planted a bomb , hidden in a crate of bottles , on the shuttle , but Palpatine sensed the assassination attempt through the Force . Trachta accompanied the Emperor , realizing that Palpatine was too cautious and shrewd to spring the trap . The bomb exploded destroying the shuttle and killing several Royal Guardsmen and stormtroopers , but Palpatine himself survived unharmed . Since the Emperor lost many of his loyal bodyguards in the assassination attempt , Trachta sent his own clone stormtroopers to replace the men killed in the explosion . However , the clone stormtroopers allowed the conspirators to invade the Imperial Palace and eliminate the Emperor in his throne room . When Kadir introduced the stormtroopers to the Emperor , Trachta informed Skosef that he was implicated in the assassination attempt , affecting in Skosef ' s role in the plan . Assassination . While Trachta planned to betray his co - conspirators , he was not oblivious to the reality that one of his allies might plan to betray him as well . Trachta ' s suspicions were confirmed when , while working in his personal quarters , an armed droid prepared to assassinate him from behind . Trachta ' s rear ocular camera allowed him to sense the attack , and he easily destroyed his would - be assassin . Unfortunately , as Trachta went to examine the destroyed droid , he overlooked Gauer who was standing just outside his room . Out in the hallway , the Grand Moff was shot in the chest , with bolts of electricity bursting from his ocular implants . Gauer dragged the remains of the droid with him , leaving Trachta ' s corpse in his personal quarters . Gauer was sent by Bartam to remove Trachta , in response to the infighting between the leaders of the coup . Meanwhile , Skosef , acting under Trachta ' s orders , assassinated Bartam and was killed by the Grand Moff ' s stormtrooper guard . With Trachta , Bartam and Skosef dead , Kadir became the leading figure of the conspiracy and attempted to eliminate the Emperor , but he and the clone stormtroopers were killed by Palpatine and his Royal Guard . Thus , Trachta never saw the conclusion of his failed coup . Behind the scenes . While developing the story for " " , writer Scott Allie originally intended Trachta to be the absolute leader of the plot to assassinate Vader and Palpatine . It was only later in the development process that he came up with the idea of the other conspirators becoming more independent and treacherous on their own . According to Abel G . Peña , the article " Imperial Betrayal " in " The Official Star Wars Fact File 122 " was supposed to imply that Trachta worked with genetics master Atha Prime , a character developed for the Kenner toy line in the 1980s , and that Prime was the one responsible for creating the clone stormtroopers under Trachta ' s command . However , the reference was removed from the released product . In the cover of " " , illustrated by Brian Horton , Trachta ' s breathing mask has a more elongated shape compared to the triangular breathing mask seen in the comic . In the scene where Gauer ' s armed droid is attempting to assassinate Trachta before it is shot itself , the reader can see what appears to be a symbol made out of the to - be - finished Death Star I on Trachta ' s door . As part of the 2008 Legacy Collection , Hasbro released a Moff Trachta 3 and 3 / 4 inch figure in their Dark Horse Comic Pack wave . The figure was well articulated with a moveable head , hinged shoulders , elbows and ankles ; he also came with a hand blaster . The pack also contained another figure , that of Darth Vader and a reprinted comic book . Although some details about his characteristic life support system and cybernetics were supplied , namely it being the result of being caught in a thermal detonator blast during the Clone Wars , the specific circumstances behind the injury were never revealed until issue 3 of the comic book arc " Star Wars : Darth Vader and the Ghost Prison .
