Many years prior. In the deeper circles.

From the screaming immaterial planes of the warp, where daemons spawn, champions battle, and souls are twisted on dark planes, came a decree of the highest importance to the mass of lowly heretics and cultists busily bloodletting and killing one another for their god's favor. An oddity indeed for the decadence of slaanesh, the fury of Khorne, the pestilence if Nurgle, and the unpredictability and madness of Tzeench to agree on anything, but not entirely alien.

The dark gods themselves, in their terrible grandeur issued an order to their subjects to claim a planet for the "honor" of the Chaotic legions, nothing more, nothing less. No soulstones to reap for she who thirsts, no Paladins or generals to corrupt, just a simple conquest and defilement for the darker powers.

And as any loyal pathfinder would scout for their cadre, or any guardsman would charge willingly toward an entrenched team of havoc gunners, the servants obliged with the greatest of haste. The hordes marched screaming and terrible from their dwellings, to war, or more specifically, their battle-barges and other transports, each zealot dreaming of building a grand and terrible cathedral in honor of their gods.

So, as one, they set out. Each ship tearing a wall in reality as it exited the warp, the hideous designs and decor of each ship's exterior enough to enduce vomit from a weaker man, and as one they sailed under the banner, the mark which had seen bloody victories and defeats on countless worlds, from Kaurava III to Cadia, the symbol of unity, and yet, of discord, the symbol which may strike a deep, sickening fear in the hearts of the most strong-willed commissar. The sharp, black, six pointed star of Chaos Undivided.

It had taken almost no time at all to reach their destination. The champions of Khorne however, with their grisly trophies clinging to sharp extensions of their red cast power armor, grew impatient on the journey, and as a result, had decreased the warhost's number by a few, meaningless dozens in a show of unnatural brutality and slaughter on their comrades, primarily out of boredom mind you. The champions of Tzeentch seemed lost in their own thoughts and schemes for the majority of the voyage. The plague bearers of Nurgle used the time to spawn new and devastating plagues for their target's unlucky inhabitants. And the followers of Slaanesh, well, they busied themselves in their own ways. Their own. Horrible. Ways.

But while the legions had their activities, few noticed the twisted servants of the machine spirit who toiled in the deep, dark, machinery pits of the assault's foremost largest ship, The Glory Of Fate, one in particular being, busy carving runes into the hull of a Chaos Dreadnought, would become of critical importance at a later time.

The world in question, meanwhile, had not heard the call of horns nor the drone of marching for ages, or at least since the Alicorn king Thunderous Might with his great bronze armor and mighty ivory horn had claimed dominance over the realm with his wife, Marvella Stealthshine, who would never be seen without her deep violet cloak and expensive black shoes, and their two beautiful daughters, (you know who they are).

All was well during the final days of their kingdom's very existence, the dragon smiths of the Anvil-strike mountains had finally signed a trade agreement with the alicorns, and the Diamond wars against the brutal mining clans of the soft valley diamond dogs had finally come to an end. And one night, while enjoying the peace and prosperity his actions had earned him, King Thunderous sat with his family and gazed at the night sky (as was their popular ritual) atop the palace's tallest tower, a young Princess Luna, who was only three years of age at the time, noticed something Very Wrong.

"Dada", she asked in a sweet tone, " what is that whale doing in the sky?" At this, Thunder let out a soft chuckle, it is simply your imagination my daughter, nothing more" He assured her. "Oh look!" A seven year old Celestia spoke with giddy enthusiasm, completely disregarding the king's response, "Luna's whales made babies!" At this Thunder looked skyward, only to have his heart fall into his deeper cavities at the sight he took in.

Ships, ships by the dozens, then by the hundreds, then to the point beyond counting descended from the "whales" in the night sky, the whales themselves being titanic versions of the smaller ships, each covered in awful decorations, strange symbols, and most of all... tubes. Thousands of tubes lined the exteriors of both the "whale" ships, and the "baby whale" ships. Thunderous was about to comment on the ridiculous nature of the design on the ships, until all of Tartarus broke free.

Each tube belched forth fire and smoke from within the ship, and where the shells hit, devastation followed. Towers crumbled, alicorns below we're screaming in fear and pain from such an unwarranted and surprising attack, but the worst of it had only just arrived. When the smaller ships had landed, hordes of bipedal creatures spilled forth from them, hacking the alicorns to pieces, while blowing his soldier's to literal pieces with strange devices almost all of them carried. Marvella burst onto the balcony, panic and sadness etched unmistakably upon her face, with her, the captain of the guard Gilded Phalanx, who informed the kind of the absolute hopelessness of a defense, upon hearing this, the king knew what to do.

The king wasted no time in unleashing his greatest weapon, but first, there was the issue of his daughters, young Celly and Lulu. "Dada please don't go!" Cried Luna and Celestia with tears in their eyes, they had been taken to a room etched with magical protection magic, unfortunately, their parents would not, and could not join them. "My daughters, I am sorry to leave you, but you must be strong for me, you must lead our people's out of this nightmare when we are gone." The king said with the greatest rarity of them all, a quivering voice.

"But Papa! Mama! Please!" Celestia cried, only to be cut off by her mother. " Lulu, Celly, we love you more than you could know, you are our sun and our moon, and will one day be the greatest rulers the land has ever known," the queen said between sobs and sniffs, and the occasional rumble of the alien weaponry hitting it's mark. "Which is why we must go my darlings, To save this world so that you might live on." Another explosion, accompanied by a strange alien battle cry. "Goodbye Luna, goodbye Celestia, we will always be with you." The royal couple said before journeying to the mage's tower, to put their plan into effect.

The court Mage wasted no time in readying the weapon, dark and powerful magics were to be used, to ensure the total demise of the enemy. The king and queen readied themselves, kissed one final time, and then went off to save their world.
