"They shall be my finest warriors, these men who give of themselves to me. Like clay I shall mould them, and in the furnace of war forge them. They will be of iron will and steely muscle. In great armour shall I clad them and with the mightiest guns will they be armed. They will be untouched by plague or disease, no sickness will blight them. They will have tactics, strategies and machines so that no foe can best them in battle. They are my bulwark against the Terror. They are the Defenders of Humanity. They are my Space Marines, and they shall know no fear."
Those were the words of our immortal Emperor, describing His plans for us, His will for us. Even now, ten thousand years after they were first spoken, those holy words still send a chill down my spine, as does the very mention of 'Space Marine' sends chills down the spines of those who would defy His will- but they are chills of a far different sort. They are the chills of the unrighteous who know that their doom is upon them.
For we are the Space Marines!
There are worlds teeming with treachery, corrupted by heresies to the immortal Emperor. Worlds that have turned their backs on His holy will. Worlds that have turned their back on the Emperor's creed, or worse, given themselves in to the silent blandishments of Chaos. To the heretic and the traitor we bring not words of chastisement, not speeches to sway their hearts, no holy texts to remind them of the true way, for it is not within the heretic to turn back from their misbegotten path. To them we shall bring nought but justice.
For we are the Space Marines!
There are worlds crawling with various xenos infestations. There are the manipulative Eldar, who seek nothing more than to reduce humanity to nothing more than their cats' paws. There are their kin, the Dark Eldar, whose desires, though equally foul, are infinitely more simplistic in comparison- they simply kill to satisfy their twisted lusts. The green skinned vermin known as the Orks are no better, and may be considered even worse in their crude, slobbering, barbaric cruelty. There are the Necrons, rising from their Tomb Worlds to expunge all life. There are the Tau, whose high-minded fantasies would deny the Emperor's glory, and reduce humanity to another mindless cog in their Empire. And then there are the Tyranids, mere animals, who exist only to consume. We shall purge them from the galaxy, so that it may be made safe for humanity.
For we are the Space Marines!
We are the holy instruments of His will, His wrath made manifest, His benevolence given form, His hopes and dreams for humanity realized. Where there are heretics, and traitors, and xenos to be purged, to them shall we take the Emperor's retribution. Where there are worlds to be protected, citizens of the Imperium to be sheltered, then there shall we stand, a bastion against the darkness that would take them. Our lives mean nothing, save that they be spent in His service.
For we are the Space Marines, and all that we are and ever will be, is for our Father
