- For information on the term that describes the wealthy, see Richece.
After the Titans rebelled against Omnius, they decided after Bela Tegeuse, to move to Richese where they remained for 70 years, often ravaged by Omnius' forces. Eventually advised by Yorek Thurr they moved to Hessra toward the end of the Jihad. Richese was devastated by Omnius soon after but retaken again by the Titans after the Great Purge.
A once powerful planet, it was at one point a main source of Heighliners for the Spacing Guild. The planet and it's moon, Korona, were famous for technological innovations which included Richesian mirrors and No-ships.
Unfotunately House Richese made an ill advised decision to engage in full-scale economic warfare with House Vernius of Ix. This led to their slow demise and fostered the popular opinion that House Richese only made copies of Ixian inventions. Part of this loss is attributed to Count Ilban Richese who spent more time with his family then with his businesses.
As a result of this failure, Ix took over the lucrative Heighliner construction.
Behind the Scenes
Though the original Dune novels by Frank Herbert made a brief mention of the planet Richese, no mention was made of a House Richese ruling it. There was also no mention of a House Vernius ruling the planet Ix.
