Ambition leads Doria, an Honored Matre, to reluctantly join the Bene Gesserit as Murbella hopes to unite the opposing organizations in Brian Herbert and Kevin J. Anderson's Hunters of Dune (2006). Though Doria seeks to learn the impressive skills of the Bene Gesserit, her Honored Matre impulsiveness and resistance to authority are difficult to shake. A chief advisor to Murbella, Doria is one of the few assimilated Honored Matres with access to sensitive Bene Gesserit breeding records. Doria and Bellonda are on opposite sides from the beginning; hoping to force them to at least respect each other's differences, Murbella makes them partners managing the spice operations on Chapterhouse. Thirteen years after the escape of the no-ship Ithaca, Doria kills Bellonda in a final confrontation.

Six years later, driven to the brink of insanity by Bellonda's incessant chatter within her mind, Doria is eaten alive by a sandworm.
