During the time of the Galactic Civil War, the Alliance to Restore the Republic operated a man-made moon. This moon was positioned in a geosynchronous orbit above their base, which was located on the planet called Fangol. Because Fangol possessed a dense mist that interfered with all communication and sensor readings, the moon was used to enable these functions for the base. It was staffed entirely by droids, and these droids were programmed to deactivate the moon if any potentially hostile ships entered the star system. The Galactic Empire ultimately destroyed the moon while conducting their assault on Fangol.
