Dortujla is a banished Bene Gesserit Reverend Mother on Buzzell. She is tasked by Darwi Odrade to make contact with the Honored Matre on Junction and set up a meeting between Mother Superior Odrade and the Great Honored Matre.
Dortujla, the head of a Sisterhood keep on Buzzell, arrives on Chapterhouse reporting that Handlers and their enslaved Futars have offered alliance, though Dortujla's Mentat analysis suggests they intend dominance. She speculates that if the Handlers found Buzzell then Matres may found it too, because smugglers would have sold their information indiscriminately. Odrade sees an opportunity and orders Dortujla to return to Buzzell with the Sisterhood's offer of surrender. Dortujla is to set up a meeting at Junction — the old Spacing Guild complex — which the Honored Matres control.
Odrade goes to meet the Great Honored Matre with Dortujla and Tamalane.
Unfortunately, Dortujla dies due to a infection by a strong biological weapon.
