Golrath
this was one of many planets on which the Alliance maintained a base during the era between the Battles of Yavin and Hoth. While on Golrath, the Alliance used an abandoned magma smelting plant to house their makeshift base. The base was eventually abandoned when the base on Arbra was established. Months later, on Arbra, they found that the native rock found on Golrath had unique properties. When heated, the rock seemed to absorb light rays from its environment and store them, almost like a two-dimensional visual recording device. When the rock cooled, it released the stored light rays just like a holovid. Leia Organa and the Alliance leaders feared that, should Golrath fall into the hands of the Empire, that the rock of the smelting plant would reveal secret information about the Alliance, including the location of the Arbra base. Unfortunately, Lieutenant Mils Giel was already on Golrath, scouring the site for clues as to the Alliance's whereabouts. This worked out to the rebels' advantage, however, for Giel himself triggered the reactor overload which would destroy Golrath Station, as part of an improvised plan to capture Leia. Leia managed to escape, as did the rest of the Alliance team, leaving Giel once again without any information to return to Lord Vader.
