Incarnate

Years have passed since last we saw our heroes become whole again.
Stallbluf, as well as the altar's precipice still serve as strongholds for the chaotic legions, but smaller raiding camps unleash parties onto the surrounding pony centers. The earth is now tainted and blackened by the foul touch of the warp, crevices open, spewing vile energies and turning the surrounding sky a dark, disturbing red.
Where this corruption has not taken place, the plague father has claimed the land, great marshes of flesh and bile putrefy all life in their vicinity, and ever spread.

Celestia looks upon the dark stronghold so close to her own Capitol, a rage foreign to her manifests itself as she views the twisted land she once called hers. Celestia had one ally in this however, a specter that would often speak with her, and had even revealed secrets of the enemy to her, leading to successful (but costly) raids of her own. She believed that her long forgotten father was speaking to her from beyond oblivion, but in reality, it was simply the Ever-changing Tzeench.
He had taught Celestia how to open a rift in the warp, so that she could speak with, view, and even aid her forces upon the field. She believed it to be a great blessing, but the warp energies were slowly shaving away at her psyche, just as planned.
The Elements had noticed something wrong for a while now. Big Mac and other stallions had been called out to enlist, but for what purpose, they had no idea. He had stopped writing for weeks, and the thought of losing another sibling drove Applejack to near madness. The loss of the other cutie mark crusaders had largely been forgotten, seeing as much time had passed. Twilight was the only element to question why some parts of the sky were red and foreboding, but the princess assured her through some strange new technique, that everything was fully under control, that some old enemies had returned, and that their extraordinary army was beating them back. In reality, with the new leadership of corporeal Parix and Elegost, casualties for this "extraordinary army" were higher than ever.
-Shady Crossing. early morning. Khornate ambush team intercepts royal raiding party.
-Chaotic forces number 20 marines, primarily berserkers, 10 cultists (Tzeench) and one blood crusher for support.
-Pony forces number 50 conscripts, 4 elite guards, 10 griffin auxiliaries, and one dragon for support.
-The battle begins.

"Take cover! Horseshoe formation on me!" One pony commander screamed to his forces, from the tree line, the enemy had cloaked themselves in foul worship, and fired upon them with their alien weapons.
The conscripts had quickly organized into "the horseshoe" which formed a ring of armor and spears to meet the enemy. Their armor had been upgraded slightly in this event of total war, and was now capable of deflecting some rounds, but by no means all. The formation held, even as some 15 conscripts and one pegasi were effortlessly shredded by the heretic's guns, and then it stopped, at first the ponies thought themselves safe, but then realized how wrong such a thought was.

From the tree line, and the opposing bank came howls of fury and zeal, as blood-red marines burrs forth, many brandishing cruel-looking axes, but their leader, who charged with a dark sword that seemed to crack with evil energies. Behind these came a beast of nightmares, who seemed to made entirely of metal, and yet, as ferocious as any living beast. Needless to say, some conscripts tried to run, and were swiftly cut down by the two commanders in the rear, no retreat in her name.
The line exploded as the dark warriors clashed with the ponies. Axes swung, armor was shredded, spears found their lucky marks, as did the bows of the griffin auxiliaries, but in the end, it came down to the dragon and the blood crusher.

The dragon had already incinerated any marine who dare challenge it, and was thoroughly amazed when the blood crusher refused to burn away, as did its daemonic rider, and soon the two were locked in mortal combat. The dragon grasped the blood crusher in its huge jaws, but again, the beast only seemed mildly annoyed by the dragon's teeth breaking against his hull. The blood crusher's rider had taken painful stabs at the creature, and with this, the dragon used its final strategy. The blood crusher, and its rider were cast to the ground, and crushed beneath the dragon's great belly. The beast felt proud at this victory, and returned to burning marines alive, until he felt a sharp pain in his underbelly. He arose, ever so slightly, to see the blood crusher ironically crushed, but the daemon's blade wedged deeply within his soft underbelly. He immediately tried to crush the pest again, but only propelled the daemon into his body. Pain unlike any other was what the dragon experienced, as the rabid little daemon shredded his internal organs as if they were nothing. Eventually, the beast crumbled and fell, it's blood dying the entire river, a deep crimson as the Bloodletter emerged from a hole in the creature's neck.

With marines hacking away at their front, and now a daemon shredding the rear, the pony formation swiftly crumbled. "Fall back to defensive posit-GALKH!" The only remaining commander tried to order his men, before a hellblade appeared jutting from his mouth. Then chaos took hold, and all squads broke.

One conscript, who had fallen unconscious in the fight, awoke in its aftermath. Bodies floating down the river, he knew this river well, it led directly to Ponyville. The moment he tried to rise, he stumbled, n auxiliary's arrowhead was lodged deeply in one of his forelegs. With his new, half submerged position, the pony took in the horrors of the crossing. All of his fellows were dead, those wounded on the banks were being executed by the cultists. Heads were taken by the red champions, and the helmets if their fallen brothers were set upon the handles of their axes, which were embedded in the ground of the bank.
The conscript thought of Ponyville, his home town, they had to be warned, someone had to survive. So he lay back, and the river 's current took him, along with a few other fallen comrades down the way. Along the course, he say the fate of the auxiliaries who fled, their wings had been torn off, and they were bound, still living, to trees along the bank. The servants of Khorne do not look kindly upon cowards, be they ally, or enemy.

So the conscript went, away from the massacre and onward to his hometown, with his face above the water, he fell into dreams again. Not knowing yet of the wrath his actions would bring about.
While deep in the Everfree, a council was taking place, which could rip the celestial empire asunder.
