The rift widens when the Bene Gesserit forces Jessica back to their home world against the express demands of Leto that Jessica should not go. Meanwhile a vendetta against Emperor Shaddam IV by a radical family member from the leadership of CHOAM wipes out many heads of the Noble Houses when a terror plot against the Emperor is carried out.
