Captivity was a moon used as a political prison by the Galactic Empire. The Empire held former rulers of conquered worlds on Captivity if they could not be kept as figureheads, but were too well-liked or otherwise too risky to be executed. While masquerading as the Rajah of Virujansi and his court, a group of Rebels were able to get themselves exiled to Captivity to rescue some of the prisoners there.
