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.

Horus Lupercal — The claim that Horus was 'recovered from the gene-labs of Terra alongside his brothers' is inaccurate; the Primarchs were scattered across the galaxy as infants and later recovered from various worlds, not from Terra's gene-labs.
Horus Lupercal — The statement that Horus was 'known simply as 'The Favorite'' is not a widely-established canon title; he was often called 'the favored son' or 'the beloved' but not formally designated 'The Favorite' as a known epithet.
Roboute Guilliman — Guilliman was mortally wounded by Fulgrim aboard the Fist of Macragge, not the Macragge's Honour.
Roboute Guilliman — Guilliman was wounded by Fulgrim's daemon sword, the Laeran blade, which was poisoned, not by the Anathame.
Leman Russ — The entry states Russ wields a 'massive Power Axe' as his weapon of choice, but his primary weapon is the Frost Axe named 'Krakenmaw' (or sometimes 'Mjalnar' in some sources), and he is also famously associated with the spear 'Gungnir' and the blade 'Frostfang
Leman Russ — The entry says Russ was 'raised by a pack of giant wolves', but canon states he was raised by the human tribe of the Russ, not by wolves themselves, though he was found among wolves and had a bond with them.
Mortarion — Mortarion was not the first Primarch to fully ascend as a Daemon while retaining his consciousness—Angron and others achieved daemonhood before him: This is incorrect. In established canon, Mortarion ascended to daemonhood before Angron; Angron's ascension occ
Abaddon the Despoiler — The Thirteenth Black Crusade is not the current or latest crusade; Abaddon has since launched further campaigns (e.g., the 14th Black Crusade in later lore).
Abaddon the Despoiler — The entry states Abaddon's ultimate design is to 'shatter the Cicatrix Maledictum across the galaxy', but established canon holds that Abaddon's goal was to create the Cicatrix Maledictum (the Great Rift) by destroying Cadia, not to shatter an already-existing
Orks — The entry states that Orks reproduce through spores that germinate rapidly without needing conflict as a trigger, but in canon, spore germination is significantly accelerated by battle and death.
Orks — The entry claims Orks can slowly regenerate lost limbs over time through their own biology, but in canon, Orks do not naturally regenerate lost limbs and rely on surgery or bionics.
Adeptus Mechanicus — The entry states that hunters of Abominable Intelligence are 'typically Inquisitorial Magos', but in canon the primary hunters are the Legio Cybernetica and specific Tech-Priests of the Adeptus Mechanicus, not typically Inquisitorial Magos.
Emperor Unification Conflicts — The Unification Wars are described as taking place over 'centuries', but established canon indicates they lasted approximately 200-300 years, not multiple centuries in a vague sense, and the Space Marine Legions were not used during the Unification Wars; they
Emperor Unification Conflicts — The claim that the Emperor 'utilized his newly created Space Marine Legions as the ultimate shock troops' during the Unification Wars is incorrect. The Space Marine Legions were created after the Unification Wars, with the first Legions (e.g., the Luna Wolves,
