Having read the "Sisterhood of Dune" twice in paperback I find it hard to believe that "Dune: Prophecy" can even be loosely based on the "Sisterhood of Dune".

Where is Vorian Atreides (who the heck is Keiran Atreides?), Reverend Mother Raquella Berto-Anirul, antimachine crusader Manford Torondo, Emperor Salvador, etc? Did Brian Herbert approve of Dune: Prophecy?

TCIII

Anyone have any hopes of what you want to see and not see in dune prophecy?

Max has released the first trailer for Dune: Prophecy, a prequel series set 10,000 years before the birth of Paul Atreides, which chronicles the origins of the Bene Gesserit. It will debut in the Autumn.
