After the Battle of Hoth, the Rebels used an abandoned magma smelting plant on the planet as their new base, Golrath Station. When the magma source dried up, Golrath Station was abandoned in favor of Arbra.
It was later discovered by the Alliance that the bedrock that comprised the station's foundations harbored several strange characteristics. When heated, the mineral compounds absorbed ambient light rays, but when it cooled, it released those rays, playing them back in the form of a hologram. Once this was learned, the Station was destroyed by Princess Leia Organa to keep the Galactic Empire from learning any secrets that the station's walls may have recorded.
