The whole daemon construct was disc shaped and razor sharp barbs of black iron lined its edges. Black, iron rib work rose up at the front of the pulpit, curved to either side of the Dark Apostle like a chariot of old, and living, bloody flesh filled the gaps between the struts. An ancient book bound in human leather was open before him and a pair of burning braziers trailed oily, black smoke in his wake.
He held his arms out wide to receive the praise of the Host, a rapturous smile upon his upturned face. He glided down until he was hovering just above the heads of the warrior-brothers and his velvet voice swept out before him as he spoke.
'Let the infidel worshippers of the Corpse Emperor witness the power of true gods!' he said, his words carrying easily over the throng of battle, though he seemed barely to raise his voice. 'Show them the power of the warriors of true faith! Let them not defile the sacred monument of the Gehemehnet! Slaughter them with the words of blessed Lorgar upon your lips! Feel the power of the gods surge within you! Kill them, my warriors! The gods hunger for sacrifice!'
The Dark Apostle lowered his defiled crozius arcanum in the direction of the enemy and his daemon pulpit began gliding forwards over the heads of his warriors. The scything daemon rays of Tzeentch screamed ahead of him, weaving deadly patterns and glowing with iridescent light.
The explosions of incoming shells erupted around the Dark Apostle, but he emerged unscathed, protected by a nimbus of light that surrounded him.
As one, the Host of the Word Bearers gave a roar of devotion and hatred, and surged forwards. The Gehemehnet rumbled behind them and Marduk could feel the presence of thousands of daemons struggling to enter the physical realm. Its time was almost upon them.
There was no glory to be had in waiting behind walls for death to come. No, the final battle would be a full attack against the enemy. Havoc squads would hold position upon the fourth tier, but the remainder of the Host was to attack in one powerful wave and engage the enemy in the open.
Marduk lifted his daemon weapon, feeling its power building as the Gehemehnet neared its awakening, and he leapt the barricade.
'Purge them of their heresies!' he roared. 'Death to the followers of the Corpse Emperor!'
The Host surged towards the enemy behind the advance of the slaves, bolters barking. Marduk was pleased to see that many of the slaves picked up weapons from fallen enemy soldiers and put them to use, shooting at their erstwhile allies. Some turned these weapons back to shoot at the Word Bearers, but they were few, and they were clubbed to the ground and murdered by their fellow slaves.
Marduk always found it pleasing to seeing former heathen worshippers of the False Emperor turn to Chaos, embracing the truth and becoming true converts, proselytes of the true Gods. The corruption of the innocent some would say, but he knew that it was something far more worthwhile. He was seeing enlightenment come to those who had been exposed to lies and falsehood for their entire lives. It was liberation and it was salvation.
The daemonic war engines that the slaves were chained to bellowed and roared as they clawed up the earth beneath them and filled the air with sprays of shells, flame and missiles. They smashed into the enemy foot soldiers and began ripping them apart and crushing them beneath their weight. Hundreds of slaves were injured as they were dragged into the fray and their chains snapped tight between the machines, entangling them with the foe.
The Host followed closely, firing into the mayhem, not caring who they killed. Thousands dropped beneath the roar of bolters, and as chains were driven into the ground and snapped, the Host broke into a run. They fell amongst the slaves and enemy, hacking and cutting with chainaxes and swords, bludgeoning with bolters and burning with roaring flamers.
Marduk saw Jarulek enter battle ahead of him, shooting down from his floating pulpit with a monstrous, daemon-bolter that caused hideous mutations in those it struck. The screaming daemons of Tzeentch scythed through the enemy, their razor-edged forms cutting limbs from bodies and cleaving through heads. The smaller daemons whirled around the Dark Apostle, eviscerating anything that came close.
Marduk saw a warrior raise a hand to hurl a grenade at the Dark Apostle, but his forearm was cleanly severed as he pulled it back for the throw. It fell to the ground as his feet. Marduk laughed as he saw the look of frantic panic on the man's face before he was hurled through the air by the force of the explosion. A pair of screaming ray-daemons cut through the air and sliced into the flailing body as if playing with a new toy and he fell to the ground in pieces.
