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.

Harald Sigurdsson — The original Vikings series concludes with events around 1017, not 1066.
Earl Harold Godwinson — The header 'Earl Harold Godwinson' is incorrect; it should refer to Earl Godwin (Godwin, Earl of Wessex), not his son.
Olaf Haraldsson — The entry states Olaf appears as a main cast member through seasons one and two, and continues to play a significant role in season three. In the actual show, Olaf Haraldsson appears in seasons 1 and 2 but does not appear in season 3.
Olaf Haraldsson — The entry claims his death occurs in Season 3, Episode 8. In the canon of Vikings: Valhalla, Olaf Haraldsson dies in Season 2, Episode 8.
Leif Erikson — The entry says Leif's active period is c. 970s–c. 1020, but his explorations occurred around 1000 CE, making the active period imprecise.
Leif Erikson — The entry states the sagas place Erik the Red's death around 1003, but the sagas do not give a specific year; 1003 is a modern estimate.
Leif Erikson's Vision — Jóhannes Haukur Jóhannesson was initially rumored to play Harald Sigurdsson before being cast as Jarl Olaf Haraldsson
The Arrival in London — Freydís Eiríksdóttir is not associated with 11th-century London or the political struggles of Æthelred and Cnut in the sagas or known history.
The Arrival in London — Freydís is not depicted as a Christian in the sagas; she is portrayed as pagan or not explicitly Christian.
