Setting

The Era Indomitus and the events that shaped it. This is the background the game is set in — established by Games Workshop, not by Creative Assembly. Nothing here tells you what the video game will do with it.

ALL TOPICS 4 TOPICS IN TOTAL

The Era Indomitus

The current period of the Warhammer 40,000 setting, opened by the tearing of the galaxy in two and by the return of a primarch to lead the Imperium’s counter-offensive.

The Great Rift

A warp storm that tore across the galaxy from end to end, splitting Imperial space in two and cutting off entire regions from Terra.

Imperium Sanctus and Imperium Nihilus

The two halves the Imperium was cut into by the Great Rift: Sanctus, which still sees the Astronomican and can therefore be navigated, and Nihilus, which cannot.

The Fall of Cadia

The loss of the fortress world that had held the only stable route out of the Eye of Terror for ten thousand years.

What is not known yet

The open questions these pages follow. Nothing here has been announced by the publisher.

?The publisher states the game is set in the Era Indomitus. It has not said which events of that era the campaign covers, or when in it the campaign begins.

?Whether the campaign map is one sector, one segmentum or the galaxy has not been described beyond “a galactic scale”.

?Nothing has been published about whether the Rift appears on the campaign map, or affects movement, communication or reinforcement.

?The publisher has described “conquering planets” and “upgrading your fleet”, but has not said what governs travel between them.

?Whether the game represents this division at all is unannounced.

?A campaign map that models unreachable regions would be unusual for the series; the publisher has said nothing about it either way.

Confirmed means a source of authority established it. Reported means an established press outlet reported it and the publisher has not confirmed it. Unconfirmed means it is expected, assumed, or inferred. Every claim on this site carries one of the three, and a date.
