Mission to Delrian A mission to Delrian was undertaken by the Confederacy of Independent Systems and the Techno Union early in 21 BBY . After his capture by the Galactic Republic on Metalorn , Techno Union Foreman Wat Tambor was transported to the remote prison planet Delrian , by request of Supreme Chancellor Palpatine . The prison ' s security firm , however , was owned by the Separatist - aligned Commerce Guild , allowing the CIS and the Techno Union access to details of the prison ' s layout and security . Tambor was allowed a visit by several of his staff — two Skakoan soldiers , posing as legal deputies , and a shapeshifting Clawdite mercenary known as Nuri . Once inside the facility , the two Skakoans blew themselves up , killing Tambor ' s clone trooper guards , while Nuri bypassed automated security with Techno Union technology and whisked Tambor to safety . The foreman traveled to Denus , Foundry to recuperate , while the Republic attempted to keep his escape hushed up . Prelude . After a failed Confederacy of Independent Systems attack on Coruscant in 21 BBY , ten months into the Clone Wars , the Galactic Republic dispatched Jedi Knight Anakin Skywalker to the Techno Union mechworld of Metalorn , where the Techno Union was producing C - B3 cortosis battle droid s . The droids were the brainchild of Techno Union Foreman and CIS Supervising Combat Engineer Wat Tambor , and had been used in the attack on Coruscant . Skywalker was able to shut down the facility and also managed to snare Tambor , exceeding expectations . Skywalker ' s capture of Tambor was a surprise to Darth Sidious , the alter ego of Republic Supreme Chancellor Palpatine , who was playing both sides and manipulating the war for his own end . Tambor ' s capture could potentially have destabilized the war and tipped the balance in favor of the Republic , which was not what Sidious wanted . In his capacity as Supreme Chancellor , Palpatine ordered that Tambor be relocated to Delrian , a remote prison world , where he would be kept under guard by a squad of eight Republic clone troopers , in addition to local security . The detainment center employed an external security firm , which happened to be owned by the Commerce Guild , an ally of the Confederacy and the Techno Union . Thus , the Separatists had access to intimate knowledge of the facility ' s defensive capabilities , security complement , and layout . Rather than launch a full - scale attack , the Techno Union planned a smaller rescue attempt , and Nuri , a Clawdite changeling from Aargau , was hired to assist them . The mission . On 14 : 4 : 07 GrS , Tambor was permitted a visit by members of his staff . Two elite Skakoan commandos , posing as legal deputies , visited the facility with a disguised Nuri . Nuri brought secret state - of - the - art Techno Union technology , which would allow him to bypass the prison ' s automated defenses . Once inside the center , the two legal deputies breached their pressure suits , releasing the compressed methane inside . This caused a large explosion , killing Tambor ' s clone trooper guard as well as the two Skakoans . In the ensuing chaos , Nuri was able to infiltrate Tambor ' s holding area and whisk the foreman to safety . Using the Techno Union technology , the Clawdite bypassed Delrian ' s automated defenses and escaped off - world with Tambor . Aftermath . Tambor was taken to his private estate in Denus , Foundry , to recuperate in a hyperbaric recharge globe , where he remained for several days . Via the CIS Shadowfeed , the Separatists lauded the daring of Tambor ' s staff , who had given their lives for the Separatist cause . The shadowfeed used the rescue as a morale - booster for Confederate worlds , highlighting the boldness of the CIS and the inadequacies of the Republic . Although the involvement of a Clawdite in the mission was known , Nuri ' s identity was kept secret . The Republic attempted to keep the story from the public , stopping the mainstream media from reporting it . Tambor ' s rescue allowed Palpatine to plot in safety once more ; with the Techno Union back to full activity , the war was evenly poised and no end was in sight . As the conflict progressed , Tambor became extremely reclusive , spending more and more time in his fortress on Xagobah . Nuri , pivotal in the rescue mission , remained in the Techno Union ' s employ as a guard of the fortress . Behind the scenes .
