In "Children of Dune", Jessica returns to Dune to inspect Paul's children, Leto II and Ghanima, to see if they can be returned to the control of the Sisterhood. Leto notes the identity of Jessica's birth mother: Tanidia Nerus. Realizing that Alia is fully possessed, Jessica survives an assassination attempt by Alia and flees to the desert once more, taking refuge with Fremen leader (and old friend) Stilgar in Sietch Tabr. A civil war has divided Arrakis, with Fremen revolting against the transformation of the desert started by Pardot Kynes. Alia's husband, Duncan Idaho, also realizes that Alia is possessed. When Alia instructs Duncan to make her mother disappear, Duncan kidnaps her on the orders of "the Preacher", a mysterious desert figure that some suspect is Paul Atreides, who disappeared into the desert. Duncan takes her to Salusa Secundus, the home of exiled House Corrino and the previous Emperor Shaddam IV. The Preacher has told Jessica, through Duncan, to train the pupil she finds there: Prince Farad'n, Shaddam's grandson. She trains him in the Bene Gesserit way, and at the end of "Children of Dune", he becomes Ghanima's concubine and Leto's Royal Scribe.
