'Maybe,' said Marduk, but he was not so certain. This place certainly felt dead, but unease nagged at him.
'Keep control of yourself, Icon Bearer,' replied Kol Badar sharply.
'The daemon is… repelled by this place,' said Burias.
A whisper of air brushed past Marduk and he swung his helmeted head to one side, scanning for movement or heat signals that would indicate an enemy presence. There was nothing. Another wisp of air shadowed by him and he raised his bolt pistol, scanning to the left. 'Something is in here with us,' he hissed. 'Anointed, be vigilant, possible hostile presence,' said Kol Badar, his words carrying to each of the Terminators through their internal comm-system. The Terminators turned left and right, weapons panning.
There was a sudden shout and the darkness was lit up as combi-bolters roared. There was a crunching sound followed by a wet splash and more bolter-fire barked.
Marduk felt a shadow rise behind him and he spun to see a towering shape looming out of the gloom, something that did not register on any of his heat or life sensors. Even with his advanced vision and the keen autosenses of his helmet, the shape was still little more than a shadow, a tapering coil of darkness that rose up to a hunched pair of shoulders. Skeletally thin arms whipped out, plunging down into the body of an Anointed warrior-brother, skewering him, and blood splashed out across the slick, black walls.
With a shout, Marduk fired his bolt pistol into the shape and he saw a shadowy face turn towards him, pinpricks of green light marking eyes amidst the darkness. With inhuman speed the creature was gone, leaping straight into the smooth, black wall, its tapering shadow tail whipping behind it as it disappeared. The Anointed warrior fell to the ground, dead. 'They are coming out of the walls,' roared Marduk, spinning as he felt another shadow flash past him. He thumbed the activation rune of his daemon-blade to life and the chainblades roared.
Shouts and gunfire erupted as more shadowy forms appeared all along the corridor, plunging their long arms into the bodies of the Anointed, killing and rending, before disappearing like ghosts.
A pair of green, glowing eyes appeared as a shape rose out of the floor before Marduk, and he swung his chainsword towards it. He saw a dark, metallic, skeletal face as the thing opened its mouth in a soundless hiss. It reared back out of range of his attack, its shadowy torso held aloft upon a long, flexible spinal cord that tapered into darkness.
He fired his pistol towards the thing's head, but the bolts passed through it as it turned to black smoke. In an instant, it had regained its metallic, physical form and lunged at him, preternaturally fast arms plunging down to impale him. He lashed out with his chainsword and threw himself into a desperate roll beneath the descending ghost creature, feeling the teeth of his weapon bite against something solid. As he came to his feet, the creature was gone.
The Terminator to his left staggered to his knees as shadowy blades punched through his head, and Marduk lashed out with his chainsword once more, the blade passing harmlessly through the shadowy, serpentine spinal cord of the creature before it disappeared back within the sanctity of the black walls.
'We have to get out of this corridor, we need more space!' yelled Burias, flailing to defend himself against a shadow that emerged to his right.
'Warriors of Lorgar! Advance, double time!' roared Kol Badar.
Marduk saw a creature descend from the darkness above, coiling down to impale another warrior upon its skeletal arms, and the man was lifted up into the air, legs kicking.
'Gods of the Ether give me strength,' Marduk heard the Dark Apostle spit, and he saw him smash his cursed crozius into the enemy. A burst of hot electric energy crackled over the dark shape as the weapon made contact, and it was smashed to the ground, its metallic limbs and long, serpentine spine thrashing feebly. The skull of the creature caved in with the Dark Apostle's next blow and the green glow of its eyes faded to darkness.
'Move out! Protect the Dark Apostle,' roared Kol Badar as he turned to give covering fire to those warriors behind him. More of the Anointed were slain as wraiths appeared out of nowhere and drove their bladed, shadow-arms through armour and flesh.
One warrior, walking resolutely backwards, his reaper autocannon roaring, caught one of the shadowy creatures in a blast of heavy fire and it was ripped apart by the awesome force of the weapon.
