Tiu Zax, an Omwati woman, held the rank of Jedi Knight during the era that came after the conclusion of the Swarm War. Her knighting occurred not long before the outbreak of the Second Galactic Civil War.
As a member of Team Tauntaun, Zax took part in Operation Roundabout, an operation with the objective of abducting Chief of State Thrackan Sal-Solo. However, mirroring the experience of Jaina Solo's Team Purella, it turned out to be an ambush, forcing Tiu's teammates, Tahiri Veila and Doran Sarkin-Tainer, to make a quick escape. Tainer came up with the plan of faking Tiu's death, which allowed him and Tahiri to get away. Following this, Tiu remained within Sal-Solo's residence, gathering intelligence. Later, she was rescued by Mara Jade Skywalker and continued her reconnaissance efforts alongside her.
