Jedi Master Vodo-Siosk Baas was a venerable Krevaaki male who served the Jedi Order with distinction into the onset of the Old Sith Wars. A warrior, historian, and expert lightsaber crafts being, Baas's was a life devoted to the training of Jedi Knights to combat agents of the dark side of the Force. A respected member of the Assembly of great Masters, Baas's time was divided between the Jedi epicenter on the world of Ossus and his academy for exceptional apprentices on the planet Dantooine. Although several of his students achieved fame for their efforts against the Sith, it was while under Baas's tutelage that a young Human named Exar Kun developed a fanatical desire for knowledge forbidden by the Jedi, and abandoned his Master's wisdom in search thereof.
