A/N: Me and my crossovers. My muse was ranting about this sort of cross, so...I have to obey. Sailor Moon and Warhammer 40K. Let's see where it goes, yeah?

Crystal Terra

Prologue: The Nature of Time

A Sailor Moon/Warhammer 40K Crossover

It is said, by some, that time is circular. As it has been, so will it be. This is the natural course of things, and if one were to wait long enough, the Great Genesis, the start of all, will once more come about, and history shall begin again. This, more or less, is true. There is, however, a world that is both apart from what we know, beyond the knowing of the mortal, and yet one with all. This is the Warp.

The Warp is a place of flux. The emotions of sentient beings feed it, and twist it and its inhabitants. There was a time, long ago, known as the Silver Millennium, when the Warp was a calmer, safer place, its inhabitants not yet Daemons, hungering for souls and destruction, but simply living. Towards the end of this period in history, however, there was a change. The Warp grew dark, and its inhabitants, hungry. They became youma, and a mighty war was waged, which not only brought low the great Moon Kingdom, but crippled what was known at the time as the Dark Kingdom. The youma, eventually, were wiped out, by beings darker still - the Daemons, and their Dark Gods. It was not long after this, as history and Immortals judge the flow of time, that these Dark Powers turned their covetous eyes towards us, humanity, and they were granted the name of Chaos. The second Great Empire of Man fell to their evil, shattering into a million worlds, each alone, lost, and afraid.

Once more, Humankind grew, and reached out, to reclaim the stars. Innovation, however, was lost, and invention deemed heresy. Technology became a religion, and Mars became its mighty bastion of knowledge. Earth grew strong, and the nearer worlds of Humanity were reclaimed, unified into an Empire. The third Great Empire of Man, and the last. The Imperium stood tall, the Mighty God-Emperor of Man leading them, his mighty Space Marines and Demi-God Primarchs hammering the Human Worlds together into a mighty engine of war, the only way to defend such a massive empire. Mars was cast from it's lofty pedestal, having resisted reintegration to the utmost, but the power of the Imperium was great, and rather than have the accumulated knowledge of millennia be lost, finally submitted in the end.

But where there is greatness, there is betrayal, and the Favoured Primarch of the Emperor, whose very name became a capital offense to speak, turned on him, and wounded him terribly, but was slain in return. Those who followed him fled, to regroup and evermore trouble the Imperium with their corruption and rebellion. Mankind grew, rediscovering lost technologies on ancient and forgotten worlds, until finally Chaos grew too strong for them. Mankind's very hatred for their foes had fed them, until they deemed it time to strike...and the Last Black Crusade swallowed the universe.

It is said, by some, that time is circular. As it has been, so shall it one day be. The universe was recreated, and the Moon Kingdom once more brought about the Silver Millennium. And once more, it fell. This time, though, there was a survivor, who was determined that there would be a second coming of the Moon Kingdom. She manipulated the timeline, fighting the inertia of the infinite universes that once had been and had yet to be, and sought to bring about a utopia, called Crystal Tokyo.

The Warp, through all of this, simply waxed and waned, never starting, never ending. The inhabitants, too, lived, and died, and were born again. Slaanesh, the one transient God of Chaos, was created in the fall of the Eldar, time and again, always dying at the hand of the Chaos Being that the Emperor became, a Being that brought relative peace to the warp, and allowed the old beings to once more live, and become youma, and fall to Chaos. The Emperor, too, would fall with each cycle, to be reborn. The new would find the knowledge of the last, and they too, tried to bring about change. As time was merely subjective, in the warp, they determined to preserve a ship, from once cycle to the next, that those aboard may pacify the universe ahead of schedule, and hopefully thus avert the dark end that had always before been met.

The ship was released from the warp as the last survivor of Moon Kingdom reawakened the souls of the Senshi, reincarnated, that her plan be brought to fruition. The Sailor Senshi, Warriors of Truth and Love, were awakened to their power, as Magos Antaeus, one of the higher Tech-Priests of Mars, finally saw his ship freed from the Warp, with its Imperial Guard cargo still...mostly intact. Without the light of the Astronomican, though, they were trapped in whatever system they were in, clearly nowhere near their destination, or even near Imperial space. There was, however, a remarkale amount of vox-traffic on that nearby planet, and since they had nothing better to do...

A/N: Well, here we go. A prologue, to set the stage. Now, the question is, do I continue? The answer: for a chapter or two, I guess. I'd need to see some response to continue it much further. Shortest story I've posted, and this chapter will probably REMAIN the shortest I've ever posted. The rest will definitely be longer than the prologue, and maybe even better!

Read and Review, please! I'd love to know what you think!
