Horizon Zero Dawn 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)

Erend — The comic does not feature Erend and Aloy hunting Korl for the murder of a merchant named Jorvik. The comic's plot involves Erend and Aloy hunting Korl, but Jorvik is not a merchant; he is an Oseram who was killed by Korl, and the murder is tied to Ersa's disa

Erend — The claim that the comic is 'set before the events of *Zero Dawn*' is misleading; the comic is set during the events of *Horizon Zero Dawn*, specifically between the main story missions 'The City of the Sun' and 'The Grave-Hoard'.

Elisabet Sobeck — The entry claims that after Sobeck's death, GAIA initiated a contingency plan using Sobeck's genetic material to create Aloy. In canon, GAIA created Aloy as a failsafe before Sobeck's death, as part of the original Zero Dawn plan.

Elisabet Sobeck — The entry says 'GAIA deactivated the Faro Plague machines' — in canon, GAIA did not deactivate them; the Minerva subsystem transmitted the deactivation codes.

Project Zero Dawn — The entry states that HEPHAESTUS worked 'in concert' to design and build animalistic machines that restored the biosphere, but in canon HEPHAESTUS was not involved in building terraforming machines like those for breaking down toxic soil; those were built by o

Project Zero Dawn — The 'DID YOU KNOW' section says Ted Faro sabotaged 'the subsystem containing humanity's history', but in canon he specifically purged the APOLLO database, not a generic subsystem.

Nora — The Eclipse cult did not successfully seize control of the Nora Sacred Lands and the Mountain; they attacked and breached the Sacred Lands, but the Nora, with Aloy's help, ultimately repelled them and the Matriarchs did not permanently flee or hide—they remain

HADES AI — HADES was not physically housed in the GAIA Prime facility; it was housed in the Grave-Hoard.

HADES AI — The Master Override was created by GAIA and stored at the Grave-Hoard, not at the GAIA Prime facility.

Project Zero Dawn — The claim that 'the machines that roam the wilds today are direct descendants and evolved versions of Project Zero Dawn's original terraforming robots' is inaccurate. The machines in the wild are not evolved descendants; they are the same terraforming machines

Project Zero Dawn — The claim that 'Dr. Elisabet Sobeck's DNA was used because she was the project lead and her genetic material was readily available, not due to any unique immunity to the Faro Plague' is misleading. In canon, Elisabet's DNA was used because she was the only hum

GAIA System — GAIA's self-destruct destroyed only GAIA and severely damaged HADES, not destroying it; HADES survived as a fragmented AI.

GAIA System — MINERVA was a separate AI (not a sub-function of GAIA) that transmitted the deactivation codes; GAIA was not yet active during that process.

Resurrection Protocol — The Resurrection Protocol is not an official term in Horizon Zero Dawn canon; the process of reseeding life is part of GAIA's terraforming system, but there is no named 'Resurrection Protocol' in the game's lore.

Resurrection Protocol — HEPHAESTUS did not corrupt the Resurrection Protocol; HEPHAESTUS was a subordinate function of GAIA that became autonomous and began creating aggressive machines to counter human hunting, but it did not corrupt a protocol specifically named 'Resurrection Proto
