Barriss Offee was a Mirialan Jedi Knight who trained under Jedi master Luminara Unduli throughout her apprenticeship. She participated in many battles in the Clone Wars, including the Second Battle of Geonosis and the Second Battle of Felucia. During the second Battle of Geonosis, Barriss Offee and Ahsoka Tano infiltrated a Separatist weapons factory in order to destroy it while Anakin Skywalker and Luminara Unduli fought aboveground. After that battle, she was infected by a Geonosian brain virus, but recovered through the actions of Ahsoka Tano. She was killed on Felucia by Clone Troopers in an AT-TE during Order 66.
