Where this setting stands
Cadia was the fortress world that held the only stable route out of the Eye of Terror for ten thousand years, and its destruction is what allowed the Great Rift to open. The publisher has not referred to these events in any material we were able to open. What connects them to this game is indirect but real: press coverage of the 7 June 2026 presentation names Cadian Shock Troops among the Astra Militarum units shown.
What the tabletop establishes
Cadia’s entire population was raised and trained for a single purpose, which is why Cadian regiments are the archetypal Imperial Guard force in the setting and why they appear in almost every Astra Militarum army. The planet was lost, and the regiments that were serving elsewhere survived it. They are, in the fiction, soldiers from a world that no longer exists, still fighting under its name — a detail that gives the most ordinary unit in the game an unusual amount of weight.
The loss of the fortress world that had held the only stable route out of the Eye of Terror for ten thousand years. Its destruction is what allowed the Great Rift to open, and it is the origin of the Cadian regiments that survive it.
Tabletop identity, as established by Games Workshop. It says nothing about the video game.What has actually been shown
The publisher has confirmed nothing about Cadia. What is reported is narrower and worth keeping separate: press accounts of the June 2026 presentation list Cadian Shock Troops among the units seen. That establishes that the regiments appear, not that the events that produced them are referenced anywhere in the game. Anyone connecting the two today is reasoning, not reporting.
What to watch next
The open question is whether a Total War game says anything about where its units come from. Historically the series has treated recruitment as an economic system: a province produces a unit type because of what it is, and the fiction attached to that unit is a line of flavour text. Cadian regiments break that model, because the province that produced them is gone. Either the campaign has something to say about that, or the most storied infantry in the setting is recruited from a generic Imperial world like any other. Creative Assembly has announced nothing. Information correct as of 17 August 2026.
What is not known
These questions have no published answer as of 8 June 2026. They are listed because an absence of information is information — and because we would rather name the gap than fill it.
