PZ - 7 was a feminine - programmed RA - 7 protocol droid manufactured by Arakyd Industries . She served the Galactic Empire at the Imperial Security Bureau base Killun Station , located on the moon Killun 71 , around the year 2 BBY . PZ - 7 worked as an inventory droid on the level of the facility that housed its Central Computer Core . Phoenix Squadron , one of the cells that made up the Rebel Alliance against the Empire , made plans to destroy the Imperial factory on the Outer Rim planet Lothal with the aid of another rebel cell . Before the rebels could initiate their attack , however , they required clearance codes for Lothal that could be accessed from Killun Station . To retrieve the codes , they dispatched former Imperial pilot Wedge Antilles , former Imperial inventory droid AP - 5 , and astromech droid C1 - 10P to the Imperial Security Bureau base . Once the rebels entered Killun Station , AP - 5 made his way to the Central Computer Core , where the clearance codes were held . Before he could enter the room in which the core was located , however , he was stopped by PZ - 7 , who noted that she had not received word of a second inventory droid assigned to that level . In order to maintain his cover , AP - 5 devised a lie , telling PZ - 7 that she had been reassigned to Killun Station ' s cargo platform and that he was replacing her . PZ - 7 told AP - 5 that she understood and departed for her new posting , allowing him to retrieve the codes for the Rebellion from the Central Computer Core . Characteristics . A loyal Imperial droid , PZ - 7 was quick to stop AP - 5 and question why he was on the level she had been stationed at in Killun Station . However , when AP - 5 stated that she had been reassigned elsewhere , PZ - 7 fell for his trick , expressing no doubt in the validity of his fib . Once she departed for the base ' s cargo platform , AP - 5 remarked to himself that he could not believe he was the same model as PZ - 7 , whom he disparaged as an Imperial drone . Like all RA - 7 protocol droids , PZ - 7 stood 1 . 7 meter s tall . She had dark plating and sensor s that would light up white when she spoke . Etched on her forehead was a triangular - like design , inside of which was a dark circle containing a horizontal oval marking , with twelve petal - like shapes protruding from all around the circle .
