List of Dune Bene Gesserit - Bellonda

Bellonda is a Reverend Mother and the chief Mentat-Archivist counselor to Mother Superior Taraza in Heretics of Dune (1984).

After Taraza's death, Bellonda serves new Mother Superior Darwi Odrade in the same function in Chapterhouse: Dune (1985). During a conversation with the Duncan Idaho ghola it is revealed that Bellonda is a descendant of Anteac, an important Reverend Mother from the time of the God Emperor Leto II. Bellonda then retrieves the following information about the origins of Mentats from Other Memory:

Order of Mentats, founded by Gilbertus Albans; temporary sanctuary with Bene Tleilax who hoped to incorporate them into Tleilaxu hegemony; spread into uncounted "seed schools"; suppressed by Leto II because they formed a nucleus of independent opposition; spread into the Scattering after the Famine.

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.
