The slaves of Despayre build the Death Star.

Planet Despayre was a penal colony that was the location of the construction of the first Death Star. The prisoners of the planet were used as slaves for the work force, and for 19 years, constructed the Death Star for the Galactic Empire.

In the year 0 BBY, Grand Moff Wilhuff Tarkin, the commander of the Death Star, tested the weapon's destructive superlaser on Despayre. It was a success: Despayre was destroyed.
