Zalin Bey, a female Human Commander, held a position within the Senate Guard as the Galactic Republic approached its end.
Throughout her time in service, Zalin displayed unwavering dedication to the Galactic Republic. She had previously worked alongside Sagoro Autem as partners. However, she advanced in rank ahead of him because he preferred field work to administrative duties. Her increased visibility led to a shift from active combat to various administrative responsibilities later in her career.
In 23 BBY, Zalin took command of the Guard unit to which Autem and his new colleague, Isaru Omin, were assigned. Her team was tasked with the investigation into the death of Senator Jheramahd Greyshade. While Sagoro and Isaru pursued the bomber, Zalin conducted her investigation within a laboratory, seeking clues. She ultimately uncovered that Venco Autem was the one responsible for the senator's assassination.
