Yashia was an Imperial soldier of the female persuasion, and a Human by species. She was under the command of the resurgent Sith Empire during the period known as the Cold War. Her assignment in 3643 BBY placed her on Korriban, where she guarded the entrance leading to the Tomb of Naga Sadow. She requested that a acolyte retrieve the remains of another acolyte who had perished; this fallen acolyte was the son of Naman Fal, a member of the Dark Honor Guard. After the recovery, Naman Fal was notified of his son's death while he was on duty at the Dark Council chambers.
Yashia, an Imperial soldier, was known for her kind nature and empathy. She would often engage in conversations with the Sith Acolytes from the Korriban academy who passed by the Tomb of Naga Sadow.
Yashia appeared to feel sorrow for the deceased acolyte, indicating a deep concern for what had happened to him. She was noticeably bothered by the thought of his corpse decaying within the tomb. Consequently, Yashia approached another acolyte in a courteous manner, attempting to convince them by suggesting that they would gain prestige as a reward for the retrieval.
She demonstrated a strong sense of duty and a thorough understanding of Korriban's regulations, including the prohibition against entering the sacred grounds.
Sentry Yashia functions as the quest-giver for the "Grave Robbing" mission on Korriban in Star Wars: The Old Republic. If the player has already finished their specific class quests, Yashia will address them as "my lord" instead of "acolyte," and she will not draw comparisons between them and Naman Fal's son. If the player character is male, they have the option of flirting with her.
