They came from behind

It was a dark day. The ground was unstable, and the winds of change where blowing. The Shas'O didn't enjoy the taste on the air. It was like a portent of doom he just couldn't shake.

For the greater good!

It was the most disgusting field of battle imaginable. Slime dripped from every branch, a river of sludge flowed through the center. The reak was horrible. They had been hidden in position for a week waiting for this moment. This was their chance to make good their strike. It was a chance to wreak havoc upon the foe before battle even commenced, then they would quietly fade into the background. There was the signal, they opened fire. One salvo, no more, and then gone. Before the foe knew what was happening the Broadside stumbled, wounded. Across the field other shots rang out, targeting anyone that stands alone. The Changer of Ways had aided his pleasure seeking brother, had changed the tide ever so much, and put into motion yet another thread in the unfathomable scheme.

Blood and Honor

"Remain in formation." Master Acaeleus' voice hissed over the comm of the land raider. As the holy tank slowed the predator tank followed suit. "This is it, where we make our stand. Croxis, position the Damocles and begin jump protocol."
"Yes Master." Croxis issued his acknowledgment of the order and as he spoke the rhino moved beside the larger tanks, its communication array scanning for enemy chatter while alerting their battle barge outside of orbit to begin deployment.

When the King falls.

As small clouds of metallic terror slowly drift across the hills and woods, the adversaries face one another. Eager to do battle, eager to draw blood. The forces of the Imperium, intent on holding the portal in the name of the Emperor, sure that the others have only foul intentions. The forces of Chaos, visions of glory and power fueling their desire to take control and rule once more. The Tyranids, intent only upon the biomass that can be harvested if the are able to reap the portals mighty harvest. Only one can be king, only one can take control. Who will triumph? Or will the portal be its own master once more.

And the blood rains down

In the far distant future, there is only war. Where untold trillions toil for the machine of war that is the Imperium of Man, where daemons bleed from the warp to slaughter in the thousands, a soul is nothing, but fuel for the fires of war. Amid this eternal carnage a strife lies Gore Swirl, a world that is not a world, a constantly changing plain of destruction, a guardian to a portal deep into the warp. He who controls the plain, controls the portal, and the destiny of the entire sector.
When battle was first joined, the Tyranids and the Sisters of Battle both fled the field, leaving only the Tau and the Acolytes of Change of the Chaos Space Marines. As the two remaining titans faced off once again to claim Gore Swirl, another army made planet fall. The Blood Angels chapter had come to play.
