Barriss Offee was a female Mirialan Jedi Knight. She carried a blue lightsaber and trained as a Padawan under Jedi Master Luminara Unduli. Offee participated in the First Battle of Geonosis that began the Clone Wars and continued to serve alongside Unduli throughout the war. Offee preferred studying ancient Jedi texts to fighting. During her time as a Jedi Padawan, Offee struck up a friendship with Ahsoka Tano, the Padawan learner of Anakin Skywalker. Though rather different in personality, the two bonded through shared experience in combat, including at the Second Battle of Geonosis.
As the Clone Wars continued, Offee grew disillusioned with the Jedi’s role in the wars, believing they had lost their way from the ideals that the Jedi Order was supposed to represent, and wary of the Jedi Council in particular. Deciding to act on her concerns, she orchestrated the bombing of the Jedi Temple as a means to foment further distrust of the Jedi. Despite their previous friendship, she allowed Tano to be framed for orchestrating the bombing, but ultimately confessed after being confronted by Anakin Skywalker, just before Tano was about to be convicted of the crime, even going as far to impersonate former Sith apprentice Asajj Ventress to frame her former friend. However, Tano’s master, Anakin Skywalker, ended up catching Offee and bringing her to justice, clearing his Padawan’s name. Offee expressed her views of the Jedi Order in front of the tribunal, showing that she had been corrupted by the dark side before being taken away.
