Dune Codexery — Data & Quality

We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

This is a fiction/fan codex: entries describe an in-universe canon. Our audits check canon and internal consistency — external fact-checking does not apply the way it does on real-subject codexes.

Recent findings (audit lane, verbatim)

Paul Atreides — Paul did not undergo the Bene Gesserit's standard Other Memory training (Spice Agony) as males cannot survive it; he accessed ancestral memory through the Fremen Water of Life ritual upon becoming Kwisatz Haderach.

Paul Atreides — Paul's arrival was accelerated by a few generations (decades) due to Jessica bearing a son instead of a daughter, not centuries earlier than the Bene Gesserit breeding program's calculated timeline.

Gurney Halleck — STATS Key Skill lists 'Lisan al-Gaib Prophecy' as a skill of Gurney; this designation belongs to Paul Atreides (Muad'Dib), not Gurney.

Gurney Halleck — DID YOU KNOW claims he plays the baliset while simultaneously engaging in high-intensity combat training; canon depicts these as separate activities and simultaneous performance is physically impossible/not described.

Chani — The entry states Chani dies in Sietch Tabr; canonically, she dies in the Imperial Palace on Arrakis (specifically in her private quarters) after a miscarriage induced by stress and political isolation.

Chani — The entry claims her death is attributed to a 'broken heart'; while emotional distress is a factor, the canonical cause of death is explicitly stated as complications from a miscarriage caused by the stress of Paul's marriage to Irulan and the resulting politi

Lady Jessica — The Water of Life ritual took place on Arrakis (in Sietch Tabr), not Caladan.

Lady Jessica — Jessica was a full Sister of the Bene Gesserit when she became Leto's concubine, not an 'acolyte' (who are initiates in training).

Thufir Hawat — The 'Weirding Way' was not adapted later by Stilgar and the Bene Gesserit; it refers specifically to combat techniques taught by Jessica and Paul Atreides to the Fremen during their rise.

Landsraad — The entry incorrectly states the Landsraad was consolidated during the rise of House Corrino; canon establishes it formed in the immediate aftermath of the Butlerian Jihad, predating the Corrino dynasty's consolidation of Imperial power by centuries.

House Atreides — The Atreides sigil is described as a 'red hawk', but House Atreides colors are canonically Blue and Silver (with the hawk typically depicted in silver/white on blue). Red is associated with House Harkonnen or the Sardaukar.

Sardaukar — The claim that Sardaukar masqueraded as Harkonnen troops during the invasion of Arrakis is not supported by Frank Herbert's original novel; they attacked openly as Imperial forces, and their identity was recognized quickly due to their combat style rather than

Sardaukar — The statement that Salusa Secundus was 'never the imperial homeworld' is incorrect; it served as the original capital of the Corrino dynasty before Kaitain became the primary seat of power.
