Polomie was a planet that became one of the many battlefield sites in the conflict known as the Galactic Civil War. In the year 1 BBY, shortly after the formation of the Alliance to Restore the Republic, a Rebel military force established an outpost on Polomie. At the same time, construction of a new military vessel, known as the Nemesis-class gunship, had just been finished. The Imperial Department of Military Research decided that the Rebel outpost on Polomie would make a sufficient field testing site in order for the experimental gunship to test its capabilities.
