The Sattva Codex (RRC 3-BG643) was considered by some a truly extraordinary document with a wealth of exhaustive detail and a breadth of continuity supplied by its addenda and appendices dating to the conclusion of the Butlerian Jihad. It was one of the priceless documents committed to the once secret archives of the Bene Gesserit. The original document constitutes a concise chronicle outlining the origin, purpose, philosophy, and character of the Holy Council of Nine as it evolved under the inspired leadership of Mother Jehanne.
