In the 41st millennium, darkness rages across the galaxy!
The Imperium of Man has lost half of its territories.
Millions of planets have fallen victim to the invasion of Chaos!
Famine, crime, and heretical cults spread like wildfire…

On the planet of Urth, located in the Imperium's dark zone, extreme suffering is taking place.

Fortunately, the savior, Eden, has arrived!

He awakens to the essence of the Warp and leads his people to prosperity!

Starting from a small, broken territory:

Farming, building armies, managing internal affairs, unifying the planet, creating Space Marines, forming a fleet, embarking on a grand expedition...

When the Lord Regent leads the Imperial fleet to reclaim lost lands, he gazes upon the flourishing star systems and the sky-darkening armada, then looks back at his own ragged ships and is left dumbfounded...

Who is the true Imperium?
