"Battle Stations of the Empire and the First Order" is a volume within the series of canon reference books called the Star Wars Encyclopedia. Its release date was June 1, 2021.
The Empire sought to solidify its galactic control with absolute authority using the Death Star, a space-based battle station. This planet-destroying weapon was intended to instill terror, and its destruction was only averted by the timely actions of the Rebel Alliance. The second Death Star, eliminated above Endor, and Starkiller Base, constructed by the First Order on the former planet Ilum, followed a similar strategy of intimidation through immense firepower. While these stations possessed unmatched destructive potential, their ultimate downfall represented a significant setback for the regimes that created them. Nevertheless, each station stood as a remarkable achievement in military and technological engineering.
