Hassik Corrino III was the fifth Padishah Emperor of the Known Universe. During his reign, the former League of Nobles and Corrino homeworld of Salusa Secundus was laid to waste by an atomic catastrophe by a renegade family, House Tantor. He secretly relocated the Imperial Golden Lion Throne to Kaitain and turned Salusa Secundus into a exiled prison planet.
The Imperial Observatory had been built by Hassik III. A builder of many grand edifices, "Hassik III had wanted to show that even after the near obliteration of the Imperial House Corrino, the Imperium and its business would continue at a more exalted level than ever before." The Golden Lion Throne itself, had been carved from a single piece of a pale blue-green Hagal quartz — "the largest such gem ever found, dating back to the days of the fifth Padishah Emperor Hassik Corrino III."
It was noted that Hassik III had taxed his subjects nearly into bankruptcy in order to rebuild a governmental infrastructure.
Lady Jessica Atreides, the Bene Gesserit concubine of the famous Duke Leto Atreides I went to the Hassik III Center for the Performing Arts (with the recently crowned Padishah Emperor Shaddam IV, the Lady Anirul Corrino, and their daughters, Irulan Corrino I, Wensicia Corrino II, and Chalice Corrino) to see the play My Father's Shadow while she was on Kaitain serving as a personal lady-in-waiting for the Corrino family.
