Bronso of Ix was an Ixian historian and author of Analysis of History. He was detained by Muad'dib's Qizarate priests charged with heresy - saying that "Paul Atreides lost something essential to his humanity before he could become Muad'Dib". His death-cell interview suggests that he was to be executed, however excerpts from Analysis of History places him alive after Muad'dib goes into the desert.
Bronso of Ix is revealed to be Bronso Vernius, the adopted son of Prince Rhombur Vernius and the natural son of his wife, Tessia; and was born on the planet Ix in the year 10,175 AG, after House Vernius's restoration to the rulership of their home planet.
Bronso was born from the artifical insemination from the sperm of the dead Tyros Reffa, who was Rhombur's half-brother, with the egg of his mother. Rhombur, was unable to conceive children due to the injuries he had suffered due his debilitating wounds received at the attempted assassination of Duke Leto Atreides I years earlier.
