Fan Casting The Old Reverend Mother in Peter Berg's Dune

The cold matriarch of the Bene Gesserit Sisterhood, keeper of a centuries-long breeding program to produce the Kwisatz Haderach. Administers the Gom Jabbar test to Paul. Spent generations planting religious folklore among the Fremen for exploitation. When Paul proves powerful, she fawns; Jessica dismisses her. The old order, broken.
