How the reference network is organized

Each article centers on a major subject from The Grimdark Historian and connects it to inline references, related records, companion episodes, topic families, and a stable public address.

How to follow the connections

Important people, factions, institutions, worlds, technologies, war machines, and conflicts are linked at their first useful appearance. Related records and episodes at the end of each article provide additional routes through the setting.

How uncertainty is handled

Warhammer 40,000 contains propaganda, retcons, unreliable narration, conflicting continuities, and unresolved mysteries. Articles preserve those uncertainties when they matter, and readers can submit corrections or references through the contact page.
