Inquisitorius / Legends The Inquisitorius was a secret division of Imperial Intelligence consisting of dark side Force - sensitive agents known as Inquisitors ( sometimes also as Inquisitioners ) , or " truth officers " . Under the control of Emperor Palpatine and Darth Vader , these Inquisitors were considered the highest ranking of the Dark Side Adepts , outranking the Emperor ' s Hand s , Prophets of the Dark Side , and lesser Dark Jedi . They reported directly to Emperor Palpatine , although they were officially classified as part of Imperial Intelligence . For a time , they were made subservient to Ferus Olin . History . The Inquisitorius was an organization established around 19 BBY by Emperor Palpatine . It consisted of agents referred to as Inquisitors tasked with hunting down Jedi who managed to survive Order 66 . Potential Inquisitors were put through a rigorous selection process . First , they were extensively tested and examined by Imperial Intelligence , then by the Grand Inquisitor , then by Palpatine himself . Applicants had to prove themselves powerful and reliable . While many Jedi fell in the Great Jedi Purge , some , such as Antinnis Tremayne and Jerec , betrayed their order and joined the ranks of both the Inquisitorius and the Emperor ' s Dark Side Adepts . If an Inquisitor captured a Jedi , it was their job to make the Jedi turn to the dark side , and join Palpatine ' s New Order . If the Inquisitor could not , it was their duty to eliminate the Jedi . Inquisitors would also search for non - Jedi Force - users to serve Palpatine . The Inquisitors were also responsible for awakening Arden Lyn after a twenty - five millennia long sleep . During this time , Inquisitor Valin Draco became involved in Sarlacc Project , the secret construction of a prototype Super Star Destroyer , showing that the order didn ' t focus solely on matters of the Force . Following the first death of Palpatine at Endor , the bureaucracy of the Inquisitorius engaged in infighting with other branches of the government to determine a successor , but some of Palpatine ' s darksider s kept silent , knowing that the Dark Lord of the Sith would return . Many Inquisitors joined the Pentastar Alignment under the title of Great InQuestor of Judgment . One of these was Jerec , who attempted to gain control of the Valley of the Jedi , but was foiled by Kyle Katarn . After the last death of the clone Emperor , the few surviving Inquisitors sent one of their failed apprentices , Brakiss , to infiltrate Luke Skywalker ' s Jedi Praxeum on Yavin IV . Luke realized what Brakiss was all along , but hoped to redeem him . When Brakiss eventually fled Yavin IV , he did not return to the Inquisitorius , but joined forces with Kueller . However , he did furnish the Inquisitorius with information about the Praxeum before vanishing . Years later , Brakiss formed a similar organization for training darksiders , the Shadow Academy , under the Second Imperium . Operations . The Inquisitors ' primary purpose was the interrogation of Jedi or particularly resistant subjects . Subjects were attained for the Inquisitors by authorization of LAACDocs . When usual methods of interrogation such as torture and Bavo Six injections failed to break a subject , Imperial Intelligence would call upon an Inquisitor , who would use powerful Force skills in conjunction with traditional but effective methods of manipulation to obtain success . In addition , several members of the Inquisitorius were themselves speculated to have been former Jedi . However , since Imperial Intelligence was quite effective in interrogating the average subject , they rarely required the services of an Inquisitor . Inquisitors instead spent much of their time looking for potential Jedi candidates and Force activity in the backwater parts of the Galactic Empire , most often in the Outer Rim Territories , at the discretion of their leader the Grand Inquisitor . Malorum , the first Grand Inquisitor , was killed on Naboo by Ferus Olin . He was succeeded by the enigmatic Hydra , who was tasked to assist Olin in locating Force Adept s , and came disturbingly close to discovering the Force - sensitivity of Princess Leia Organa on Alderaan . Lord Laddinare Torbin , the next Grand Inquisitor , was killed by an assassin droid who crashed a shuttle into the Imperial palace on Weerden sixteen years prior to the Battle of Yavin . The title was eventually taken up by the Zabrak Ja ' ce Yiaso . The Inquisitorius , while classified as a branch of Imperial Intelligence , report directly to the Emperor . The Inquisitorius was originally based on Coruscant , in the Jedi Temple under Malorum and later in the Senate Tower under Hydra . Afterwards , the foreboding Citadel Inquisitorius was built on the planet Prakith in the Deep Core ; here , the High Inquisitor s were given their assignments and conferred with their colleagues . Captured Jedi were imprisoned and tortured here . The Citadel ' s security was breached on at least one occasion , by allies of Bail Organa . As of 18 BBY , all Inquisitors could be distinguished by enveloping , dark maroon robes of zeyd - cloth that invoked images of dark blood . This uniformity may have been discontinued with time . They used Ultrachrome protection , with Taozin amulet s creating a void in the Force so its wearer could not be detected by another Force - sensitive . Largely because of their secret nature in the Imperial Intelligence department , they received very few mentions even in the official field manual for the Imperial Military , " " , with Luke Skywalker , himself a Force - user , suspecting that the agency was kept secret by Emperor Palpatine due to their use of the Force , and also wondered if even the Imperial Military trusted them . Behind the scenes . Agents of the Inquisitorius are most commonly known as " Inquisitors " , but some sources such as " Zirtran ' s Anchor " use the term " Inquisitioner " . The term " Nobody expects the imperial inquisition ! " , is a reference to Monty Python ' s " Nobody expects the Spanish Inquisition ! "
