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.

Michael Corvin — Michael does not burn in sunlight during Underworld: Evolution; he is shown to be immune to UV radiation as a hybrid, and it is Selene who burns in sunlight in that film.
Michael Corvin — Michael's daughter Eve is not born in Underworld: Evolution; she is conceived at the end of that film but is born off-screen and appears in Underworld: Awakening.
Death Dealers — The entry states Viktor was 'metamorphosed by Markus Corvinus, the first true Vampire.' In canon, Markus was the first Vampire, but Viktor was turned by a different Vampire (not Markus) after being wounded in battle; Markus did not personally metamorphose him.
Death Dealers — The entry says Viktor was offered immortality by Markus Corvinus in exchange for his military expertise and army. In canon, Viktor was turned by a Vampire lord (often depicted as a different Elder or a coven leader) after being mortally wounded, not directly b
Vampire Hunters — Selene was a normal child until Viktor murdered her family when she was a young woman: In canon, Selene was a child, not a young woman, when her family was killed.
Lycan Resistance — The entry says 'Amelia was killed and bled dry by Lycans led by Lucian during an attack on her territory.' In canon, Amelia was shot with a silver bullet by Lucian, not bled dry.
Lycan Hierarchy — Viktor did not create Lycans using his own blood; he used the blood of a captured werewolf (William) to create the first Lycans.
Lycan Hierarchy — Lucian was not the first Alpha to rebel; he was the first Lycan to lead a successful rebellion, but the term 'first Alpha' is misleading as he was the first Lycan to be born with the ability to control his transformation and lead the uprising.
Marcus Corvinus — The entry states Marcus was born in the 6th century or later, but canon establishes he was born in the 5th century.
Marcus Corvinus — The entry claims Viktor falsely claimed to be the first vampire, but in canon, Viktor claimed to be the first of the 'true' vampires, not the progenitor.
Michael Corvin — The entry claims Michael was bitten by both a Lycan and a Vampire, but in the films he is bitten only by a Lycan (Lucian) and then later infected by Selene's blood, not bitten by a Vampire.
Michael Corvin — The entry claims Michael was 'apparently killed by Markus Corvinus in Underworld: Evolution, though he actually survives that film' — this is incorrect; Michael is not killed by Markus in the film, but he is gravely wounded and later survives, so the phrasing
Lucian — Lucian is not the first hybrid; the first hybrid is Michael Corvin.
Lucian — Lucian is not the first Lycan; the first Lycan is William Corvinus.
