The " Terror " was requisitioned by Grand Admiral Martio Batch to guard the development of the Galactic Empire ' s new cloaked starfighter , the TIE Phantom — a project Sarn hoped would help him to win Emperor Palpatine ' s favor . During an inspection by the Dark Lord of the Sith Darth Vader , two Rebel agents , Rookie One and Ru Murleen , infiltrated the " Terror " and destroyed it along with the TIE Phantom production facility on Imdaar Alpha . Vader escaped the " Terror " but executed Sarn for his failure before leaving . Biography . TIE Phantom project . The Human male Sarn served as an officer in the Imperial Navy during the reign of Emperor Palpatine . By 3 ABY , Sarn had reached the rank of admiral and had been given command of the Super Star Destroyer " Terror " . At his research station on the moon Imdaar Alpha , Grand Admiral Martio Batch was working to develop a practical cloaking device . The devices had once been common , based around stygium crystals mined from Aeten II in the Dreighton Nebula , but became rare after the mines ran dry . After a failed attempt to produce cloaking devices based on hibridium , Batch used the Empire ' s " Tarkin " superweapon to destroy Aeten II , an explosion that released thousands of stygium crystals into space . The Grand Admiral used the new supply of stygium to begin production of cloaked starfighters — modified V38 assault fighter s known as TIE Phantoms . To protect his project , he had Sarn and the " Terror " transferred to Imdaar Alpha . Sarn saw his involvement in the project as an opportunity to win favor with the Emperor . Following the Imperial victory over the Alliance to Restore the Republic at the Battle of Hoth in 3 ABY , the Empire began testing the new TIE Phantoms in the region of space known as the Dreighton Triangle , using reports of unexplained events in the region ever since the Battle of Dreighton during the Clone Wars as a cover for its operations . When the Dark Lord of the Sith Darth Vader traveled to Imdaar Alpha to inspect the progress of the project , Sarn arranged a demonstration of the new fighters , dispatching Sigma Squadron to intercept a flight group of Rebel X - wings as they patrolled the Dreighton Triangle and instructing his crew to ensure that it proceed flawlessly . Observing aboard the " Terror " , Sarn was impressed with the performance of the fighters , which destroyed all three Rebel ships before they could respond . Vader , however , was impatient to end the testing stage and turn the TIE Phantoms loose on the Rebel Alliance . Death and legacy . Vader remained aboard the " Terror " while the field tests were completed . Sarn informed him that the TIE Phantom fleet was ready for full deployment , and was ordered to take the " Terror " back to Imdaar Alpha . When the Rebel Alliance learned that the " Terror " was en route to Imdaar , it dispatched pilots Ru Murleen and Rookie One to infiltrate the Star Destroyer and steal a TIE Phantom for study . Infiltrating the supply base on the planet , the Rebel agents stole a " Lambda " - class supply shuttle and used it get aboard the " Terror " as the ship prepared to dock with the cloaked TIE Phantom factory . The intruders were soon discovered but successfully evaded capture . On Vader ' s orders , Sarn doubled the search patrols in an effort to locate the Rebels , but the interlopers were able to reach the hangar and board a TIE Phantom . The Rebels used their stolen fighter to attack the " Terror " main reactor , causing it to overload before making their escape . Sarn ' s crew attempted in vain to stop the reactor from going critical while Vader ordered Sarn to undock the " Terror " from the TIE Phantom factory . When Sarn reported that docking controls were inoperative , the Sith Lord executed him for his failure , using the Force to telekinetically strangle the admiral . Vader escaped the " Terror " moments before its destruction . As the Star Destroyer exploded , it caused the TIE Phantom factory to become visible . The Rebels flew their stolen fighter inside and destroyed the facility , which brought an end to the TIE Phantom project . Knowing that he had failed the Emperor , Grand Admiral Batch took his fleet and fled to the Outer Rim Territories . However , his crew was still loyal to Sarn . Following the Emperor ' s death at the Battle of Endor in 4 ABY , Batch ' s crew assassinated the Grand Admiral and joined Warlord Blitzer Harrsk ' s splinter faction in the Deep Core . Personality and traits . Sarn was an ambitious and conceited officer who saw his involvement in the TIE Phantom project as an opportunity to win the favor of Emperor Palpatine . He regarded the Force powers possessed by Darth Vader as mysterious . Fearful of Vader ' s abilities , Sarn was careful not to anger the Dark Lord . When Vader was sent to inspect the project ' s progress , Sarn was determined to ensure a flawless demonstration . Despite Sarn ' s efforts , the project was ultimately sabotaged by Rebel agents , and Vader used his powers to execute the admiral . Behind the scenes .
