It is a time of darkness and despair.
In the grim darkness of the 41st Millennium, the Emperor has long since departed from the world of mortals, and His demigod sons no longer walk amongst mankind.
The future of humanity is naught but endless darkness and the flames of war. Its destiny seems to be a slow, inexorable decay, rotting from within the bloated and sclerotic shell of its own Imperium.
Until souls from another world arrived.
"Alright lads, I've got good news and I've got bad news. Which do you want first?"
"Let's have the good news."
"The good news is, we've been reincarnated. We're in a vast, interstellar age, and we are now transhuman super-soldiers—two hearts, three lungs, the works. It also seems we came with a complimentary power-up... one that feels very... WAAAGH!"
"Brilliant! Isn't this the classic overpowered protagonist treatment from one of those portal fantasy stories? I can't wait to start living it up! Think we can bring our folks over? Right, so... what's the bad news?"
"The bad news? Back home, we called this universe Warhammer 40,000."
"..."
In the stunned silence that followed, they collected themselves and began to explore this strange new universe.
They learned to adapt, for their old reality had left them no path of return.
They wept like Gretchin who'd had their toes trod on, yet still found the courage to march forward.
In the grim darkness of the 41st Millennium, humanity was given another chance at renaissance.
But this time, could Mankind seize it?
Let the war begin!
From the skies of Holy Terra to the galaxy's farthest edge.
Let the Sea of Stars boil.
Let the stars themselves be blinded.
Let us bear witness, once more, to a galaxy liberated.
Liberated by Mankind.
