The Third Sister (Moses Ingram), also known as the Reva Sevander, is a major antagonist of the Star Wars Spin-Off series, Obi-Wan Kenobi.
She was an inquisitor to the Imperial Empire. Before that, she was a Jedi youngling when Anakin Skywalker (now Darth Vader) and clone troopers attacked the jedi temple to hunt down and destroy the jedi knights. She watched how Anakin slaughtered her fellow younglings and swore revenge against him. During the rise of the empire, she joined and became a member of Inquisitorius. She was very ambitious and attempted to hunt and track the whereabouts of an exiled Jedi fugitive, Obi-Wan Kenobi to gain Darth Vader's favor.
