Do Paul Atreides And Chani End Up Together In The Books?

Though Paul and Chani live together for many years after the end of “Dune,” they’re unable to have a child together once Paul becomes emperor. In the first novel, Chani actually gives birth to Paul’s son, whom they name Leto II, while the two are living in the desert fighting the Harkonnens. The child is tragically killed in an attack shortly afterward. Villeneuve’s “Dune: Part Two” completely cuts Leto II out of the story due to the film’s truncated timeline.
“Dune Messiah” reveals that Chani hasn’t been able to conceive another child since Leto II because Irulan — still hoping to secure the Atreides bloodline for the Bene Gesserit by compelling Paul to have a baby with her — has been slipping a contraceptive into her food for years. Paul allows this to happen because he sees visions of Chani dying in childbirth and is afraid to lose her.
Ultimately, Chani does get pregnant and gives birth to twins at the end of “Dune Messiah” — another boy named Leto II and a girl named Ghanima. The effort proves too much, however, and she dies just as Paul had foreseen. Devastated that his vanity and arrogance ultimately still caused the love of his life’s death, Paul steps away from his role as emperor and walks into the desert.
