As Sah and his troops entered the atmosphere, Sev ordered him to secure an outpost and warned his Padawan to remain on his guard. Shortly thereafter, the ARC trooper accompanying Sev received a directive from Supreme ChancellorPalpatine commanding him to execute Order 66, which labeled the Jedi Knights as traitors to the Republic. Sev was attacked by the clones under his command but managed to defeat many of them before being overwhelmed and killed. After the Jedi Master's death, the ARC trooper sent a detachment of clones to eliminate Sah, who was able to defeat his clone squad.[1]
The Weequay Sev wore brownJedi robes[1] and used a lightsaber containing a greencrystal.[4] He cautioned Joc Sah, his Padawan learner, to remain on guard during the mission to Ragmar V, warning him that a seemingly minor fight could erupt into a large battle.[1]
Sev was powerful enough to achieve the rank of Jedi Master. He was also skilled in using his lightsaber during combat, eliminating multiple clone troopers before he was overwhelmed and slain.[1]
In 2008, Hasbro created an action figure of both Sev and the ARC trooper under his command as part of the second wave of the Order 66 release of the Star Wars: The 30th Anniversary Collection toy line. Sev's figure comes with a green lightsaber.[4]
