Ketku Sadar was a Tholothian Jedi Sentinel of the New Jedi Order and the Padawan of the elderly Jedi O'choa Pyne. Shortly before the Massacre at Ossus, Pyne believed that the Jedi were fated to be destroyed by the One Sith and so she and her Padawans fled to the obscure planet of Kluistar in order to escape their fate. Pyne's prediction proved to be accurate and the Third Jedi Pirge went underway. Sadar was the third child of a family of Tholothian nobles, and was a highly skilled Jedi, with proficient knowledge in the Force, lightsaber combat, slicing, computers and mechanics. In addition, Sedar's constant companion was a Corellian banshee bird named Sierra. In battle, Sedae wielded a lightsaber with a bondi blue blade.
