X-TR0, a battle droid equipped with feminine programming, served the Shroud as a guardian of the museum situated on the volcanic stratum of The Coil. In the year 3630 BBY, X-TR0 identified trespassers within the museum's confines and initiated an attack, concurrently requesting their departure in a courteous manner. Nevertheless, HK-55 and Z0-0M were successful in overcoming and dismantling the droid.
