Eragon 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)

Brom — Brom's dragon was killed by Galbatorix, not Morzan.

Brom — Brom did not leave the Rider order long ago to dodge Galbatorix; he was one of the last surviving Riders who fought against Galbatorix and only went into hiding as a bard after the fall.

Murtagh — Murtagh was not raised by Galbatorix from childhood; he was raised by his mother Selena until her death when he was around eight, then lived as a fugitive before being captured by Galbatorix as a teenager.

Murtagh — Murtagh does not leave Alagaësia at the conclusion of the story with Eragon's blessing to explore unknown lands beyond the sea; in the main Inheritance Cycle, Murtagh and Thorn fly away to live in seclusion within Alagaësia, and the journey beyond the sea is f

Fírnen — Fírnen's scales are described as blue shifting toward green, but in canon his scales are consistently described as blue with no canonical mention of them shifting toward green based on mood or health.

Dragon Riders — The Fall left only two survivors—Brom and Oromis (and his dragon Glaedr)—who fled into hiding. This is incorrect: Oromis and Glaedr were not survivors of the Fall at Doru Araeba; they were already in hiding at Ellesméra before the Fall, and Brom was the only R

The Empire — The entry implies the Forsworn served Galbatorix for nearly a hundred years, but they were active for only a few decades after the fall of the Riders and were all dead long before the main story.

Brom's Sword (Zar'roc) — Eragon learned the sword's true origin from Brom's story in Teirm, not after Brom's death

Brom's Sword (Zar'roc) — Zar'roc did not remain by Eragon's side throughout the war; he gave it to Murtagh after the Battle of the Burning Plains

The Dragon Egg (Saphira's) — The egg hatched during the Battle of Farthen Dûr, not at the climax of the first book

The Dragon Egg (Saphira's) — Brom did not recognize it immediately; only after Eragon showed it to him and he examined it closely did he realize its true nature

The Rescue from Durza's Dungeon — The rescue occurs in Tronjheim, not Farthen Dûr; Farthen Dûr is the mountain containing Tronjheim.

The Rescue from Durza's Dungeon — The dungeon door is iron, not wooden; Saphira breaks through an iron door.
