Bene Gesserit
In "Chapterhouse Dune", Logno assassinates Great Honored Matre Dama with poison while the Bene Gesserit forces are attacking Junction. Logno, the former chief advisor to Dama, assumes control of the Honored Matres and immediately surrenders. Bene Gesserit leader Odrade is surprised, but she and Miles Teg soon realize they have fallen into a trap. The Honored Matres use "the Weapon" and turn defeat into victory. Murbella saves as much of the Bene Gesserit force as she can and they begin to withdraw to Chapterhouse. Odrade, however, had planned for the possible failure of the Bene Gesserit attack and left Murbella instructions for a last desperate gamble. Murbella pilots a small craft down to the surface, announcing herself as an Honored Matre who, in the confusion, has managed to escape the Bene Gesserit with all their secrets. She arrives on the planet and immediately announces her intentions by killing an overeager Honored Matre with a blinding speed enhanced by Bene Gesserit training that makes her faster than any Honored Matre before her. Murbella is taken to Logno, and immediately declares herself hostile. Logno cannot help herself and attacks, Murbella disposes of her and some allies. She takes charge of the Honored Matres, who are awed by her physical prowess.
