Galen Erso's Office was the dedicated workspace belonging to the scientist Galen Erso. Within his office, Erso dedicated his time to the study of bug tech and blueprints which had been dispatched to him from Geonosis. Darth Vader, along with ISB loyalty officer Sid Uddra, made their way to Erso's office while looking into the acts of sabotaging that had been hindering the Galactic Empire's construction of the Death Star. During their time in the office, Vader came to understand the actual intention behind Commander Krennic's and Governor Wilhuff Tarkin's favored initiative, and also learned that Erso had received an ootheca from the saboteurs situated on Geonosis.
