Bene Gesserit
The Honored Matres make many attacks on Bene Gesserit strongholds throughout the known bounds of the Old Empire. They mark the Bene Gesserit Bashar Miles Teg and the Duncan Idaho ghola for death, destroying the Gammu Keep in an unsuccessful attempt to kill Idaho, and annihilating the planet Rakis with their Obliterators, killing Teg.
