Sarna was a Sith trooper and Sith officer of the Human female persuasion. She was stationed on the planet Taris during the Sith occupation in 3956 BBY. Her official rank was Junior Officer First Class.
Shortly after Darth Malak's Sith forces seized control of Taris, Sarna decided to host a gathering at her residence, providing an opportunity for some troopers to unwind. Despite warnings from her friend Yun Genda about its strength, she consumed a great deal of Tarisian ale at the party and became intoxicated.
It's possible Sarna encountered the amnesiac Revan, along with Carth Onasi in the Upper City Cantina, unaware that they were actually Republic officers.
After she lost consciousness, Revan and Carth stole her armor.
Sarna was a young woman characterized by red hair and brown eyes. She maintained an optimistic view of life, even while serving in the Sith military.
Sarna's dedication to the Sith was non-existent. She was simply trying to earn a living. She even expressed her desire to retire her uniform if she could secure alternative employment.
During her conversation with Revan, Sarna found herself becoming interested in the soldier.
Sarna will only extend an invitation to the player if the player's character is male; if the player's character is female, they interact with Yun Genda instead.
As an alternative to attending the party, the player can travel to the northern section of the Upper City, specifically the North Apartments. There, the player might witness an Aqualish member of the Hidden Beks being threatened with death and harassed by Sith soldiers. The player has the option to intervene and save the Aqualish victim or allow the Sith Soldiers to execute him and then threaten the soldiers. Regardless of the player's decision, they can loot a Sith uniform from one of the corpses. Once this event occurs, Sarna and Yun Genda will no longer be present in the game.
