Portal Desolate
this strange device was left behind by the Order of the Terrible Glare on Garn. The holographic image of Rur was maintained here, as a guardian and vindicator of the Order's work, should the Jedi Knights return to Garn. It was destroyed when Luke Skywalker told Rur's image that the Jedi had been wiped out by Emperor Palpatine. The central computer couldn't reconcile this fact with its programming, and exploded.
