Sashana was a female Mirialan Jedi Master serving the Jedi Order and the Galactic Republic during the Galactic War and the ensuing conflict with the Eternal Empire. The Eternal Empire campaign saw Jedi numbers thin over time, leading to surviving Jedi going underground. Jedi Master Gnost-Dural recruited her to join him on Ossus.
A Force-sensitive Mirialan female, Sashana was trained by the Jedi Order in the ways of the Force. She would eventually rise to the rank of Jedi Master. Sashana would be one of the many Jedi to join Jedi Master Gnost-Dural in hiding on Ossus in the aftermath of the surprise attack of the Eternal Empire on both the Sith Empire and the Galactic Republic. Sashana would be on planet in 3630 BBY when the Sith Empire sent their forces to eliminate the Jedi stationed on Ossus. Sashana would be killed by an Imperial spacer sent to eliminate the Jedi in the Great Library.
