Firwirrung Master Firwirrung was the lead entechment specialist onboard the Ssi - ruu k ship " Shriwirr " . He was the master of Dev Sibwarra , and , along with Elder Sh ' tk ' ith , had been responsible for studying him since his capture . Firwirrung was killed onboard the " Shriwirr " when his plan to capture Luke Skywalker for entechment experiments backfired , and the Jedi — with the freed Sibwarra ' s help — captured the ship during the Battle of Bakura . Biography . Brown - scaled , Firwirrung achieved great power despite his youth and standing as a part of the Ssi - ruuvi caste considered as outcasts . Around 2 BBY , Firwirrung was assistant to entechment chief Yifaii . Yifaii was present at the Ssi - ruuvi invasion of G ' rho . There , a young human boy named Dev Sibwarra was spared from entechment and Yifaii considered that he might warrant further study on Lwhekk . It was decided that the boy should be given to Firwirrung . In 4 ABY , Firwirrung was now entechment chief himself onboard the " Shriwirr " during the Ssi - ruuk invasion of the planet Bakura . Since beginning his military service , he had made many improvements to entechment technology and his great ability to manipulate , repair and design entechment apparatus allowed him to advance far beyond other members of his caste . He was not well - regarded by superiors and shipmates , including Admiral Ivpikkis and even those from his own caste who regarded him as overly ambitious and not worthy of the praises he had been given . Firwirrung was still the master of Dev Sibwarra and treated him like a companion or pet . Dev slept in Firwirrung ' s quarters and had great devotion to the entechment chief , despite torture and cruelty inflicted upon him by the Ssi - ruu over time . When news came of an outsider , someone like Dev with Force abilities , it was decided that the entechment apparatus should be modified appropriately . Firwirrung ' s plan was to modify it in a way that would allow a Force - user to pull energy from humans at great distances . Within hours , Firwirrung designed , built , and tested a device such as this , a task that would take most Ssi - ruuk engineers weeks , months or even years to complete . The updated entechment apparatus was tested on Dev , who , under brainwashing from Elder Sh ' tk ' ith , was more than willing to be the test subject . Having bargained with the governor of Bakura , Wilek Nereus , a group of Ssi - ruuk , including Firwirrung , Sh ' tk ' ith and Dev , infiltrated Bakura and landed on Pad 12 . They planned to capture the Force - user , Luke Skywalker , and bring him to the " Shriwirr " . This they did successfully , but the Jedi had managed to break Dev free from his brainwashing . Following this , Dev tried to hide his feelings from the Ssi - ruuk . With Luke their prisoner , he was brought to the entechment laboratory and bound to the chair . However , Dev was revealed to be free of brainwashing and all of the lights in the laboratory went out . Luke had used the Force to manipulate a P ' w ' eck into attacking a control board . Firwirrung and Sh ' tk ' ith escaped . Firwirrung began work at once on a second entechment chair while Elder Sh ' tk ' ith and some P ' w ' ecks confronted the escaping Luke and Dev at Deck 16 . Soon , Luke and Dev made it to the engineering deck where Firwirrung had been working . Now , he and a group of P ' w ' ecks ambushed the pair . Firwirrung accused Dev of betrayal and shot him down , rendering him hurt by the shot . In the " Dominant " , Commander Pter Thanas executed a blast on the " Shriwirr " . As a result of this , Firwirrung was killed by the blast . Personality and traits . Firwirrung was aggressively innovative , always seeking to construct better entechment devices and sought to do the best job possible .
