Beart system

From Tardis Wiki, the free Doctor Who reference

The Beart system was the star system in which Fluren's World was located. It was situated in the Vienna Cluster. Beart-54, a sun in the system, was held back from supernova by a time bubble. The appearance of the Unon triggered an emergency deactivation of the time bubble and allowed the supernova to destroy Fluren's World. (COMIC: Weapons of Past Destruction)
