Sashal, a Keshiri female, held the title of Sith Lady within the Lost Tribe of Sith, holding a position on their governing Circle of Lords. Despite her reportedly petite frame and Grand Lord [Darish Vol]'s assessment of her as unintelligent, Sashal was, in reality, a woman of considerable intellect and power, evidenced by her seat on the Circle of Lords.
In the events of the Liberation of Coruscant, Sashal found herself among the Sith forces trapped within the New Jedi Temple. During the final battle there, the Sith Lady, acting on the counsel of Vestara Khai, spearheaded an attempt with a group of other Sith to assassinate Allana Solo; this endeavor ultimately failed, resulting in the deaths of Sashal and her Sith companions.
