Guilde spatiale
The final two novels in the series were to be called "The Throne of Dune" (formerly "Irulan of Dune") and "Leto of Dune" (perhaps "The Golden Path of Dune"). However, in a July 2010 blog post Anderson announced that these novels had been postponed due to plans by Herbert and Anderson to publish a trilogy (later known as "Great Schools of Dune") about "the formation of the Bene Gesserit, the Mentats, the Suk Doctors, the Spacing Guild and the Navigators, as well as the solidifying of the Corrino imperium."&lt;ref name="7/15/2010 blog"&gt;&lt;/ref&gt;
