|Chronological and political information|
Selene was born at the time of the Mandalorian Wars and decided to join the sith during the start of the Jedi Civil War. During her time, she met a young man named Dustil Onasi, who was the son of Carth Onasi. The two were close, and she felt sorry when Dustil's homeworld, Telos IV, was had been bombed by the Sith Lord Darth Malak, who had betrayed his former master, Darth Revan. Believing that the sith could help Dustil, she convinced him to go with her to Korriban and attend the Academy. They arrived to the academy, which was under the leadership of Headmaster Uthar Wynn, a former apprentice who overthrew his master, Jorak Uln. During her training at the academy, Selene had some problems in dealing with the dark side, and felt that being a sith was her worse mistake. Trying to earn her respects to Uthar, she decided to step down, but she decided to spend her relationship with Dustil and hinder his progress of being a sith. Dustil really loved Selene, and remained close together. However, Uthar discovered their relationship, and found Selene as an obstacle to Dustil's training. Seeing that she had no experience in the dark side, Uthar had no choice but to eliminate her, and put an end to their relationship. The plan worked when Uthar sent Selene on a mission in the Valley of the Dark Lords, and Selene was killed by the headmaster. Dustil was concerned of her disappearance, but Uthar lied that Selene was killed during a mission, in which he planned. Dustil was heartbroken, but he continued his training in the academy.
The true circumstances behind Selene's death were revealed to Dustil by his father, Carth Onasi, and a redeemed Revan. Dustil was angry and upset that Uthar lied to him, and finally seen the deception of the dark side. He agreed to leave the academy and warn other students about the cause and convince them to leave with him.
