Death Star project
Shortly after the opening of the Clone War with the First Battle of Geonosis, Darth Sidious had given Mas Amedda and the Strategic Advisory Cell the plans for an ultimate battle station called the Death Star, capable of destroying entire planets. Amedda selected Lieutenant Commander Orson Callan Krennic to work on the project and agreed with krennic's suggestion to use the plans' creators, the Geonosians, to help with the station's inner workings. Amedda advised Governor Wilhuff Tarkin to become more involved in the project.
