Belsus was the moon of Gentes in the Anoat system. It was the location of Ugnaught Main Rendering Plant 908, where Flynn Kybo died trying to kill Grievous, who had crushed all resistance on the planet. Grievous had attempted to establish a laboratory for study of the Force. The underground cities were devastated when the moon's thermal core was destroyed by Kybo.
