A BX-series droid commando was stationed at the Citadel on Lola Sayu during a Republic mission to free Jedi Master Even Piell, who was being held prisoner there with other republic officers such as Wilhuff Tarkin. When the rescue team managed to successfully free the prisoners, this droid and a number of other commando droids accompanied Warden Osi Sobeck to the dungeon where Piell's naval officers had been held. The commando reported to Sobeck that Piell and Piell's officers had escaped, and the angered Phindian responded by ordering another BX-series commando to execute the droid.
