For information on the term that describes the wealthy, see Richece.
Richese was the fourth planet in the Epsilon Eridani star system, and classed with Ix as supreme in machine culture since both planets escaped the more severe effects of the Butlerian Jihad. Richese was noted for miniaturization.
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.
Years later, Korona was destroyed by Imperial Sardaukar forces, as it was being used to store spice illegally.
