'Open your mouth,' came the voice of an overseer at his ear, but Varnus resisted. Pain jolted through him as the overseer ran one of its needle fingers along his neck, and he opened his mouth wide in a cry of pain. The chirurgeons darted eagerly forwards with their mechanical hands, whirring power clamps gripping his front teeth. Without ceremony, the teeth were ripped from his jaw. Blood poured from the holes in his gums and he groaned in pain.
Yet the chirurgeons had not finished their brutal surgery. Gripping his head tightly, one of them leant forwards with another mechanical device, and Varnus tried to pull away from it desperately, blood running down his throat and spurting over his chin. He could not escape the attentions of the twisted, hunched chirurgeon, however, and as its partner hit Varnus's lower jaw to close his mouth, the first sadistic creature slammed its mechanical device into the side of his face.
A metal, barbed staple, half a hand-length wide, punched through the bone of Varnus's jaw and cheek, pinning his mouth closed. The metal bit deep into the bone, and Varnus gargled in agony. A second staple punched into the bone on the other side of his face.
That was when the black, tentacled thing was brought towards him. The chirurgeon thrust the fighting thing at his face and Varnus screamed, his jaw stapled shut, in pain and terror. He tried to turn away, but his head was held tight and the box was placed over his mouth.
He screamed and screamed as the four questing tentacles probed his skin, the touch stinging and burning his flesh. The tentacles felt their way across his face, and with horror he realised there was a fifth, thicker tentacle pushing through the gap in his front teeth and into his mouth. No, it wasn't a tentacle, he realised as his tongue touched the vile thing. It was a hollow, fleshy tube, and as it entered his mouth it began to expand and push itself down into his throat, flattening his tongue against the base of his mouth.
Two tentacles latched under Varnus's jaw, burrowing into his flesh to secure a tight hold, and the remaining two leech-like appendages wriggled across his cheeks, probing at the corners of his eyes before burrowing agonisingly into the skin at his temples. He roared in excruciating pain, the sound alien and strangely mechanical to his ears, altered by the thing clamped firmly over his mouth and nose. He breathed in deeply which was heavy and difficult, and he felt a foul, sickly sweet taste in his mouth and nose.
White-hot pain shot through his head as the tentacles burrowed further into his flesh. They ceased wriggling within him, but the pain remained. His breathing was laboured and the figures above him went hazy, spots of light appearing before him, and he fell into the nightmare of his unconsciousness.
The warriors of the Adeptus Mechanicus stepped inexorably forwards, like a seething, relentless carpet, spread out across the hard-packed salt plain. Some amongst them were almost human, though even these were hard-wired into the weapon systems they bore, their brain stems augmented with mechanics and sensors. The Coryphaus had seen their like before. He had fought against loyalist members of the Cult Mechanicus on their Forge Worlds during the advance on Terra ten thousand years earlier. More recently, he had fought alongside those members of the Machine Cult that had long sworn their allegiance to the true gods, the powers of Chaos.
Sheer cliffs rose up on either side of the valley their tops hidden by dark, brooding, heavy cloud. The rumble of thunder boomed from the heavens and flashes punctuated the dark, threatening sky. The insides of the massed, bulbous clouds lit up as lightning crackled within, arcing, skeletal fingers of electricity that clawed across their surface.
The rain had been falling for almost an hour, hard and driving, lashing down upon the servitors as they plodded forwards at the impulse of their masters. The ground beneath their feet was pooled with salt sludge. The grinding tracks of weapon platforms and hissing crawlers ripped up the ground, creating mires in their wake as they slowly advanced amongst the serried cohorts of mindless and augmented servitors.
Visibility was poor across the open ground, as waves of driving rain were driven into the valley by the fierce winds that were picking up.
Screaming shells descended out of the gloom, accompanied by the constant ramble of artillery that was almost indiscernible from the sound of the building storm. They fell from the high ridges to either side of the valley, obscured by cloud and rain, and detonated amongst the ranks of servitor warriors, sending flesh and mechanics flying in all direction. Red blood and pale, unnatural fluids mixed with the pooling waters underfoot. They made no cries of fear or pain as they were destroyed, though even if they had they would not have carried through the pounding torrents of falling rain.
