The new HBOMax tie-in series, 'Dune: The Sisterhood' will be based on Brian Herbert and Kevin J. Anderson's novel, Sisterhood of Dune. The story centers around Valya Harkonnen, the leader of a blossoming order of women, and her vendetta against Vorian Atreides.
Vorian was the son of a human cymek--a disembodied brain in a machine body--raised in the synchronized worlds by the super-computer Omnius. He defected during a war between thinking machines and humans, and he eventually played an integral part in defeating them in the Battle of Corrin.
In the Sisterhood of Dune, some years have passed and humanity is rebuilding. Vorian lives under an assumed name. He watches over his descendants and does his best to hide his extended lifespan. He's a historical figure, with paintings and lore. It's impossible to imagine the story without him.
