An Imperial I-class Star Destroyer served under the command of Captain Slavin of the Imperial Navy during the year 1 BBY. Slavin piloted the Star Destroyer to the Tonnis sector, where it was scheduled to meet with Freighter 2716. This freighter was transporting an enormous kyber crystal originating from the Jedha system. The rebel Saw Gerrera destabilized the crystal in an effort to prevent the Galactic Empire from turning it into a weapon, resulting in the destruction of both the Star Destroyer and the freighter.
