An officer was a member of an Imperial Military unit tasked with seizing the Galactic Republic's Adrenal Research Base situated on Quesh, during the Sith Empire's invasion of the planet circa 3642 BBY. As the Jedi Padawan Sajar used telekinesis to hurl the deceased bodies of Imperial scouts at the assembled Imperials stationed outside the base, the officer identified the Jedi as Darth Sajar, a previous member of the Empire's governing Dark Council. The officer promptly notified the Empire about Sajar's presence, and predictably, the Sith Emperor sent the Emperor's Wrath Lord Scourge—his own personal executioner—to Quesh with the intent to eliminate the betrayer.
The Jedi Knight class mission "The Emperor's Wrath" in Star Wars: The Old Republic, a video game that was launched by BioWare in 2011, was the first mention of this Imperial officer.
