Selene

Selene was a female Human Sith apprentice who studied at the Sith Academy on Korriban. She and Dustil Onasi were close friends, and Selene convinced Dustil to join her at the academy. Academy headmaster Uthar Wynn held Dustil in high regard, seeing him as one of the academy's most promising students, but thought that Selene showed little talent as a Sith. Wynn secretly ordered his acolytes to kill Selene because he thought that she was impeding Dustil's training; he later told Dustil that Selene had been lost on a mission to the Valley of the Dark Lords.

The true circumstances behind Selene's death were revealed to Dustil by his father, Carth Onasi, and a redeemed Revan. Upon hearing this news, Dustil, who had finally seen how evil the dark side could be, agreed to leave the academy.

Behind the scenes
Selene (latinized Selana) is the Greek name for the moon, as well as it's goddess and it is rarely used as a female name (mainly in fiction).
