Zaerdra was a pale-skinned female Twi'lek who lived in the Lower City of the Outer Rim world of Taris during the time of the Mandalorian Wars and the Jedi Civil War. A member of the Hidden Beks, a swoop gang that was one of the largest in the Lower City, she served as the personal bodyguard of the organization's leader, Gadon Thek. She participated in resistance activities undertaken by the Beks against the Mandalorian occupation of Taris in 3,963 BBY. A devoted ward of Thek, she met the fugitive Jedi Padawan Zayne Carrick with suspicion when he returned to Taris while looking for his comrade, the Snivvian con-artist Marn Hierogryph. Zaerdra also held fellow Bek Griff Vao in low esteem, threatening him if his sister, Mission, was ever caught rummaging in her belongings.
Some seven years later, during the height of a street war between the Beks and a rival gang, the Black Vulkars, which had been taken over by former Bek Brejik, she greeted the amnesiac former Dark Lord of the Sith Revan, accompanied by Republic officer Carth Onasi, with open hostility. Her indignant warnings forced Thek to apologize to his guests and to remind Zaerdra that he could still take care of himself. After Thek recruited the pair to reacquire a prototype accelerator that the Vulkars had stolen, she objected to the gang leader allowing Revan to ride the swoop that the accelerator had been installed on for the Tarisian Season Opener. During a massive orbital bombardment, ordered by Darth Malak to prevent the escape of Bastila Shan, Taris, including the Lower City, was utterly devastated.
