Star Wars: Every Sith Who Turned To The Light Side

Yuthura Ban was a Twi'lek who was captured and forced into slavery to Omeesh the Hutt. When she was rescued by the Jedi, they invited her into their ranks. However, Yuthura was left so traumatised during her time as a slave, she perceived the Jedi's strict codes as a form of oppression, inspiring her to abandon their teachings. Joining the Sith Academy, the young Twi'lek became an apprentice to the Sith Headmaster, Uthar.

When Yuthura met Revan, she asked Uthar to allow him into the Sith Academy. In reality, Yuthura and Revan teamed up and successfully slaughtered Uthar, allowing Yuthura to become the new Headmaster. Even though she perceived Revan as an ally and friend, the Dark Side compelled Yuthura to turn on Revan.

After a brief fight, Revan defeated Yuthura but spared her life, giving her the chance to return to the Light Side. Upon reflecting on the mistakes she made on her life, Yuthura accepted Revan's proposal.
