Queta Welmin was a human Jedi Master who lived during the Clone Wars and the years leading up to it. Queta was one of several Jedi studying to become trainers for the new generation of Jedi. When Master Michel Kringe resigned his position as Battle Master, Queta was quick to apply. However he narrowly lost out to Master Jake Inman.
However, this ended up being a good thing for Queta as when the war broke out he was able to join the spy network established by Jedi Master Tholme. Queta was instructed to report to the Jedi of the 77th Airborne and developed a close friendship with many of them.
Queta eventually decided to join the 77th's final battle in the war. Taking part in the siege of Tatooine he led his troops bravely. However, when Order 66 was issued he was completely unprepared for the deception and he was killed by his Clone Troopers.
