The Scarif vault was a six-story-high data vault located within the Citadel Tower of the Imperial security complex on the tropical Outer Rim planet of Scarif. The vault held scientific treatises, bureaucratic memoranda, and schematics, including the plans to the Galactic Empire's planet-destroying battle station, the Death Star. In 0 BBY, the Rebel Alliance squad "Rogue One" infiltrated the data vault and stole the station's technical readouts in order to locate its fatal weakness.
