The Machine Crusade

The Machine Crusade is the second novel in the Legends of Dune prequel trilogy. While it continues the narrative from the first book, Butlerian Jihad, it also sets up events for the final installment, The Battle of Corrin.

This novel is part of a prequel series that explores the origins of key elements in Frank Herbert's original Dune universe, such as the Butlerian Jihad and the rise of the Bene Gesserit, Spacing Guild, and Mentats. It details the ancient war against sentient machines that shaped the future of humanity.

As of my last update, The Machine Crusade has not been adapted into a film or television series. The primary focus for adaptations related to the Dune universe has been on Frank Herbert's original novels.
