"It is the 41st Millenium. In the grim darkness of the far future...

...there is only war.

The Emperor of mankind wages a constant battle to protect humanity from the horrors of space. All that stands in their way are the mighty Adeptus Astartes.

They are more than mortal, they are steel and they are doom, they are the champions of mankind. But not even the angels of death alone are enough to stop the great terrors of the warp and they leave that duty to their beloved Emperor, the one who has used his very mind to hold the warp at bay.

But nothing lasts forever.

The Adeptus Mechanicus have uncovered a terrifying and bitter truth, the Emperor is now dying and there is nothing they can do to save him. Should he die, then the terrors of the warp will pour through and eradicate the Imperium, wipe them from existence. The loyal Astartes refuse to let that happen and to this day they have traveled the great ocean of stars searching for something, anything to either prolong his life, or save him entirely.

Ever since this terrible truth was uncovered, the common folk of the Imperium who are eternally loyal to the Emperor have had such information kept from them for fear of the Imperium erupting into chaos. However, there are those who know of what is to come and they have decided to aid the Imperium in their search for the answer to save the Emperor.

May the Emperor watch over them, until he can no longer."
