The Mirialan Padawan to Luminara Unduli, Barriss preferred learning and studying the ancient Jedi texts in the Temple to being in the midst of war. A bit older than most Padawans, she follows everything her Master says to the letter, without question. So when she must work together with the young and impetuous Ahsoka in the middle of a battle, she must use all her training to survive the war and Ahsoka's extremely forward nature.
Luminara Unduli served the Jedi Order in the final years of the Galactic Republic. A green-skinned female humanoid, Luminara was a trusted advisor to the Jedi Council and the Republic government. When crises demanded it, she and her faithful Padawan learner, Barriss Offee, would rush into the thick of conflict, where their incredible talents with the lightsaber blade served them well. Following Order 66, the fate of Luminara remained a mystery. Yet 14 years after the formation of the Empire, an underground Holonet transmission revealed that she was being held in The Spire prison. It was all a ruse, however; Luminara was dead, her body used as bait to draw surviving Jedi Kanan Jarrus and his apprentice Ezra Bridger into the Inquisitor's clutches.
