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.

Reg — Reg was not discovered by Riko alone; he was found by Riko and her friends (including Nat and Shiggy) in the first layer.
Reg — Reg was not discovered in the 'Edge of the Abyss'; he was found in the first layer, specifically in the Seeker Camp area or nearby ruins.
Bondrewd — Bondrewd's widely-known epithet is 'Bondrewd the Novel', not 'Bondrewd the Novelist'; the latter is a mistranslation/misattribution.
Bondrewd — Ido Front is not located at the bottom of the fifth layer; it is situated on the fifth layer's 'Sea of Corpses', near the gateway to the sixth layer, not at the bottom itself.
Ozen — Ozen first appears in Made in Abyss Manga Chapter 10 (or Volume 2) and in Season 1 Episode 8 of the anime, not Chapter 1 or Episode 2.
Ozen — Ozen is the one who discovered Reg and brought him to the surface, and she has direct knowledge of his origins, so she does have a known connection to Reg's creator (Lyza).
Ozen's Research Team — Nanachi was not rescued by Bondrewd from a cursed state; Nanachi was a child from the surface who voluntarily underwent the elevator experiment with Bondrewd in Layer 5, resulting in transformation into a narehate.
Ozen's Research Team — Nanachi never joined Ozen's team; Nanachi lives independently in the Seeker Camp and has a cooperative but non-member relationship with Ozen.
City of Orth — The entry states the Rim is Layer 0 and outside the Abyss proper, but in canon the Rim is part of the first layer and Orth is on the edge within the Abyss's influence.
City of Orth — The entry lists Nanachi (past) and Reg (past) as notable residents of Orth, but Nanachi lived in the 4th Layer and only visited Orth briefly, and Reg was found in the Abyss and is not a resident of Orth.
The Black Whistle — The entry incorrectly lists Ozen as holding the Black Whistle rank; she is a White Whistle.
The Sunken Land — The Sunken Land is the fifth layer of the Abyss, not the sixth.
The Sunken Land — The Sunken Land lies beneath the Sea of Corpses, not the White Whirlpool.
The Nameless Children — The claim that the Nameless Children are surface-dwellers stranded in the lower layers who lost their names due to the Curse is not supported by canon; they are children born in the Abyss who never had names.
The Nameless Children — The statement that their primary settlement is in Layer 5 is incorrect; the only known settlement is the Village of Iruburu in Layer 6.
