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.

Floki — The entry states that Flóki's daughter Geirhildur drowned near the Shetland Islands, followed by a stop in the Faroe Islands where his daughter Geirhildur wed. This is contradictory: the same daughter cannot both drown and later wed. According to Landnámabók,
Floki — The entry says Flóki's companion Herjólfr earned the nickname 'Herjólfr Butter' for claiming that butter was smeared on every blade of grass. The historical nickname is 'Herjólfr hinn fagri' (Herjólfr the Fair) or 'Herjólfr smjör' (Herjólfr Butter) in some sou
Lagertha — The entry states that King Frø of Sweden killed King Siward, who is explicitly identified as Ragnar's grandfather, but Saxo does not state this relationship.
Lagertha — The entry says Ragnar's son Siward was wounded in battle, but Saxo does not explicitly identify this Siward as Ragnar's son; the identification is ambiguous.
Rollo — The entry states Rollo died in 933, but the widely accepted historical date of his death is between 928 and 933, with most sources placing it around 928–932; the specific year 933 is not definitively confirmed and is often considered too late.
Rollo — The entry says 'historical sources do not confirm he personally commanded it' regarding the Siege of Chartres in 911, but most historical accounts attribute the leadership of the Viking force at the Siege of Chartres to Rollo himself, making the phrasing misle
Hvitserk — The claim that Hvitserk's pyre was made 'specifically from human heads (or skulls)' is presented as a definitive detail, but the saga's wording is ambiguous and may be symbolic or exaggerated, not necessarily literal.
Hvitserk — The LORE section says Hvitserk was 'captured by a foe so large that victory was impossible', which is a vague embellishment; the saga says he was captured by a large army after his own forces were defeated, not by a single 'foe'.
House of Wessex — The show uses the name 'Ecbert' (with a 'c'), not 'Egbert', for the character who negotiates with Ragnar.
House of Wessex — Winchester is not consistently depicted as the primary capital throughout the show; the court is shown at various locations.
House East Anglia — The entry states King Edmund was executed by Ivar the Boneless and Ubba, but in the series 'Vikings', Edmund is executed by Ivar and Hvitserk, not Ubba.
House East Anglia — The 'Did You Know' section states King Edmund was one of the first major Saxon rulers defeated by Ivar and Ubba in Season Four, though King Ælla was defeated earlier, but both are in Season Four, making the comparison misleading.
Fenrir — The cord named Gelgja is attached to a boulder called Thviti, which is sunk deep into the ground: In the Prose Edda, Gelgja is a cord attached to a peg, not to Thviti; the chain Gleipnir is fastened to the rock Gjöll, and the boulder Thviti is sunk into the gr
Fenrir — A sword is thrust into his mouth, with the hilt against the lower jaw and the point against the upper, to gag him and keep his jaws open: The sword is placed to keep his jaws spread open and prevent him from biting, not specifically to 'gag' him, which implies
Ragnarok — Heimdall and Loki kill each other in the standard accounts, not just Heimdall slaying Loki.
