In "Hunters of Dune", the 2006 sequel to "Chapterhouse Dune" by Brian Herbert and Kevin J. Anderson, it is noted that Bellonda is one of the few Bene Gesserit with access to sensitive breeding records, and one of even fewer possessing the memories of all the Mothers Superior. Bellonda suspects that the Honored Matres had originally been Reverend Mothers sent out in the Scattering, and calculates that melange withdrawal and hypnosis had caused them to deny their origins. Thirteen years after the no-ship "Ithaca" escapes from the planet Chapterhouse, Bellonda is killed in a duel by her Spice Operations Director partner and nemesis, the former Honored Matre Doria. An outraged Mother Commander Murbella, leader of the merged New Sisterhood of Bene Gesserit and Honored Matres, forces Doria to share minds with Bellonda before her memories are lost forever.
