Bartam held the title of Grand Moff within the Galactic Empire and was a Human. Similar to Grand Moff Trachta, Bartam had undergone cybernetic augmentation, making him a cyborg.
Bartam participated in a conspiracy alongside Grand Moff Trachta and Moff Kadir with the goal of assassinating Emperor Palpatine and Darth Vader. However, internal conflicts arose among the conspirators, resulting in conflict within the group. Bartam orchestrated the death of Trachta by ordering Gauer, another member of the conspiracy, to shoot him.
Yet, immediately following Trachta's assassination, General Skosef, a fellow conspirator, turned on Bartam and killed him, only to then be killed by Bartam's stormtrooper bodyguard.
