Yoggoy, a planet situated within the Unknown Regions, was characterized by its landscape of mounds reminiscent of the Castle Lands. Flowers brought over from Alderaan adorned its surface. The Tachyon Flier met its end on Yoggoy in 27 ABY at a site thereafter referred to as the Crash. The Killiks from the Yoggoy hive resided there, and it also functioned as the capital for the Colony.
