The DS-Orbital Battle Station, known unofficially but more commonly as the Death Star was a massive Imperial battlestation with a diameter of 100,000 meters designed to enforce law and order throughout the Empire.
- "I guess this explains what the Empire wants with all those Wookiee slaves, the scum you’d usually find in an Imperial prison couldn’t build that monster. Not in a thousand years."
- ―Ben Kenobi upon seeing the Death Star for the first time
Even before the Death Star became fully operational, its detention blocks began to fill with detainees. Political troublemakers, Rebel insurgents, and dangerous pirate forces, as well as myriad other enemies of the Empire, were made to quietly "disappear" from public view within the enormous prisons of the incomplete battle station.
