Zinsian functioned as a desiccant-type preservative.
A deposit of Zinsian was unearthed on the world of Brosi, situated within the Corporate Sector. The Corporate Sector Authority opted to construct a trio of Zinsian refinement facilities (Delta 1, Delta 2, and Mailor). In order to achieve this, they forcibly relocated a multitude of indigenous Brosins, and numerous young male Brosins were "employed" by overseers to participate in perilous mining operations. Subsequently, the Brosins established the Brosin Underground with the aim of combating this industrial exploitation.
