Zinsian was a dry preservative.
A vein of Zinsian was discovered on the planet Brosi, in the Corporate Sector. The Corporate Sector Authority decided to build three Zinsian processing plants (Delta 1, Delta 2 and Mailor). To do so, they displaced thousands of native Brosins, and many young male Brosins were "hired" by supervisors to work in dangerous extractions. The Brosins then created the Brosin Underground to fight this industrial activity.
