A Twi'lek receptionist, working for the Sith Empire, was stationed within the main lobby of the Tarisian military base. The Twi'lek was clad in a combat suit.
This Twi'lek had been employed at the base prior to the Sith's takeover of Taris. After the Galactic Republic was ousted, the base was transformed into the center of Sith governance on the planet, under the control of a Force-sensitive Sith Governor. She was on duty when Revan infiltrated the base, seeking to acquire the launch codes necessary for him and his allies to escape the planet.
Initially, she confronted Revan's party, threatening to alert the Sith troopers within, potentially leading to a battle. However, after being convinced otherwise, she departed without incident.
