An EV-series medical droid, designed with feminine programming, functioned as an interrogation droid within the Citadel, a prison facility situated on the planet of Lola Sayu. This facility was under the control of the Confederacy of Independent Systems during the era of the Clone Wars. Subsequent to the capture of Jedi Master Even Piell by Separatist forces, her mission was to forcefully extract the coordinates for the Nexus Route from him. The Nexus Route was a crucial hyperspace lane leading directly into the territories of both the Galactic Republic and the Confederacy. However, during the droid's torture of Piell, Clone Captain CT-7567 fatally shot her in the head. CT-7567 had infiltrated the Citadel alongside a team of clone troopers and several Jedi with the objective to rescue Master Piell from the Separatist hold.
The feminine EV-series medical droid served as an interrogator droid in the Citadel. This [prison](/article/prison] was originally constructed 500 years prior to the Clone Wars by the Galactic Republic as a holding facility for rogue Jedi on the planet of Lola Sayu. Nevertheless, control shifted to the Confederacy of Independent Systems when they seized Lola Sayu early in the Clone Wars conflict.
This droid, a feminine EV-series medical droid, was encased in dark gray plating accented with blue and black markings, and its height was 1.74 meters. Its elongated head featured multiple antennae on top, a row of four red photoreceptors on the lower section, and a fifth photoreceptor on its forehead. The Citadel's insignia was prominently displayed on the right side of its head. The droid was supported by two slender legs and possessed two pairs of arms – one set attached at the shoulders and another emerging from its midsection. A needle was integrated into its upper right arm. It demonstrated a willingness to employ torture to obtain the coordinates of the Nexus Route, even prepared to extract Even Piell's remaining eye to achieve its objective. It remained steadfast as Republic clones fired upon its droids, but emitted a scream of pain upon its own destruction and deactivation.
This droid's debut was in "The Citadel," the eighteenth episode of Star Wars: The Clone Wars' third season, a canon animated series. Her voice acting was provided by Dee Bradley Baker.
