Set centuries before the events of Dune: Part One and Part Two, Max’s Dune: Prophecy miniseries promises to explore the origins of the mysterious Bene Gesserit order. Tasked with guiding the Known Universe and humanity along what they deem to be the best possible path, the Bene Gesserit have all manner of strange and superhuman abilities. However, the matriarchal order is far from the weirdest part of Frank Herbert’s Dune. In fact, as the core novels continue, the sci-fi epic’s strangeness deepens, introducing everything from human-sandworm hybrids to doppelgngers of the dead.
