Additional Details

"Atreides, the Distinguished's mate. Sabula females are larger than males--making her even deadlier than Atreides. Photosensitive, she spends most of her time underground."


  • Gesserith's name may refer to the "Bene Gesserit", a powerful social, religious, and political sisterhood from Frank Herbert's Dune universe. Immense sandworms are key components of the universe, which adds to the allusion.
