Luminara Unduli was a Force-sensitive female Mirialan who served as a Jedi Master and Jedi General in the fading years of the Galactic Republic. She was a valued adviser to the Jedi High Council, the Supreme Chancellor, and the Galactic Senate. During the Clone Wars, she fought with her last Padawan, Barriss Offee, and she was a common and formidable presence at points of crisis, on worlds such as Ilum, Nadiem, and Geonosis. She was killed during the Battle of Kashyyyk when Contingency Order 66 was enacted.
Luminara Unduli was calm and patient, and her former Padawan, Barriss Offee, noted that she was a skilled teacher. Master Unduli sometimes scolded people but rarely actually lost her temper with them. She was confident in her abilities, but this confidence became overconfidence when she fought Asajj Ventress and almost cost her life. Unduli was grateful to Ahsoka Tano for saving her from Ventress and told her she owed the Padawan her life. Quinlan Vos thought that she was one of few Jedi to easily connect with and she complemented her companions during battle.
Unduli greatly cared for her apprentice, Barriss Offee, nevertheless she maintained a very professional relationship with her. Keeping in mind the Jedi sense of detachment, Unduli was prepared to let go of Offee in the event of her possible death. She was also gifted with a sense of humour, as she stifled a snort of laughter at Anakin Skywalker's "simple logic" during the Second Battle of Geonosis.
