OW: No Surrender

For more than a hundred centuries, the Emperor has sat immobile
on the Golden Throne of Earth. He is the master of mankind by
the will of the gods, and master of a million worlds by the might
of his inexhaustible armies. He is a rotting carcass writhing
invisibly with power from the Dark Age of Technology. He is
the Carrion Lord of the Imperium for whom a thousand souls are
sacrificed every day, so that he may never truly die.

Yet in his deathless state, the Emperor continues his eternal
vigilance. Mighty battlefleets cross the Daemon-infested miasma
of the warp, the only route between distant stars, their way lit
by the Astronomicon, the psychic manifestation of the Emperor’s
will. Vast armies give battle in his name on uncounted worlds.
Greatest amongst his soldiers are the Adeptus Astartes, the
Space Marines, bio-engineered super-warriors. Their comrades
in arms are legion: the Imperial Guard and countless planetary
defence forces, the ever-vigilant Inquisition and the Tech-Priests
of the Adeptus Mechanicus, to name but a few. But for all their
multitudes, they are barely enough to hold off the ever-present
threat from aliens, heretics, mutants—and worse.

To be a man in such times is to be one amongst untold billions. It
is to live in the cruellest and most bloody regime imaginable. These
are the tales of those times. Forget the power of technology and
science, for so much has been forgotten, never to be re-learned.
Forget the promise of progress and understanding, for in the
grim, dark future there is only war. There is no peace amongst the
stars, only an eternity of carnage and slaughter, and the laughter
of thirsting gods.
