Biography
During the conference between the Separatist and Galactic Republic delegations regarding the legitimation of the Separatists’ government, held in the throne room of Duchess Satine Kryze, junior senator Lux Bonteri entered the room and, with the Duchess’ permission, delivered an embittered accusation against Count Dooku for his involvement in the murder of his mother.

The Separatist attendants then ordered this droid and a fellow one to take Lux to the vessel which brought the Separatist delegation to Mandalore and was then put before the holographic projection of Count Dooku, who denied any involvement in Mina’s death. The Count then ordered these droids to execute Lux, but he was saved by padawan Ahsoka Tano who had followed him to the vessel and took out the droids.
