During the time of the Clone Wars, Trace Martez was the proprietor of a repair shop. This establishment was situated on Level 1313 within the underworld of Coruscant. Having inherited the business following the death of her parents, the shop was strategically positioned next to an underworld portal. It boasted a landing platform extending into the shaft. Within this shop, Martez housed a customized Nebula-class freighter, which she affectionately called the Silver Angel. The fateful encounter between Martez and Ahsoka Tano, the former Jedi Padawan, occurred when the Togruta's malfunctioning speeder bike crashed onto the repair shop's landing pad.
In the later Imperial Era, the Martez sisters forged an alliance with Rex, the former clone captain, who occasionally utilized their shop's facilities. Following Rex's successful rescue of Senator Riyo Chuchi from a clone sniper dispatched by Admiral Rampart, they brought the captured assassin to the shop for interrogation purposes. However, the clone refused to cooperate and swiftly ended his own life using a suicide shocker. Rex soon reached out to Clone Force 99 for assistance in Senator Chuchi's investigation of Rampart, who had been concealing the Imperial destruction of Tipoca City located on Kamino. The group's ship, the Marauder, landed on the shop's landing platform, where they convened with Rex and Chuchi to discuss their plan. This plan involved acquiring evidence of Rampart's involvement from his Venator-class Star Destroyer so that Chuchi could present it to the Imperial Senate.
