Bene Gesserit
The Bene Gesserit practice "religious engineering" through a faction called the Missionaria Protectiva, which spreads "infectious superstitions on primitive worlds, thus opening those regions to exploitation by the Bene Gesserit". Collectively known as Panoplia Prophetica, these myths, prophecies, and superstitions provide the opportunity for a Bene Gesserit to later cast herself as a guide, protector, or some other figure in fulfillment of a prophecy in order to manipulate the religious subjects for protection or other purposes. These myths also exploit religion as a powerful force in human society; by controlling the particulars of religion, the Bene Gesserit have a manipulative lever on society in general. The Bene Gesserit also employ the Missionaria Protectiva to prepare the Empire for its Kwisatz Haderach.
