'Enkil, turn!' roared Kol Badar as a wraith dropped down from the darkness behind the warrior. The Coryphaus stepped forwards, pumping fire towards the dark shape looming over the warrior, but the shots passed straight through the creature. Enkil turned, swinging his heavy weapon around to bear, but the shadow was too quick and it drove twin-bladed arms through his body. He fell to his knees, blood pumping from the wounds. Kol Badar roared as he stepped forwards, his combi-bolter barking as the injured warrior tried to push himself to his feet. Three wraiths appeared around him like looming spectres of death, their arms raised, poised for the kill.
The Coryphaus took another step towards the fallen warrior, but a hand on his arm halted him.
'Coryphaus, we must leave this place,' said Burias, his eyes glittering like molten silver.
With a snarl, Kol Badar shook off the Icon Bearer's hand, but nodded his head.
'The gods be with you, Enkil,' he said, firing a final burst towards the gathered wraiths as they killed the warrior. He turned and moved as swiftly as his armour allowed him, passing the rearguard walking steadily backwards, fire barking from their weapons.
Marduk ran ahead of the Anointed warriors, unencumbered by the bulky Terminator armour they wore, and the corridor gave way to a vast open area. Steps rose to a large circular dais that dominated the room, surrounded by dozens of columns glowing with green hieroglyphs. A black-sided pyramid stood in the centre of the dais, a miniature replica of the structure they were within, some ten metres in height.
He scanned left and right as he ran, seeking out any sign of the enemy, and he leapt up the steps and onto the circular dais. He circled and realised that dozens of corridors similar to the one he had just exited, branched off this large, circular room, spaced evenly around the perimeter. Darkness, impenetrable even to his eyes, was beyond these corridors, but he had the impression that they all led back up towards the surface. Everything was perfectly symmetrical and it made sense that none of these corridors led further down. The circular room rose up high into darkness - no ceiling could be seen - and the cylindrical open space projected straight up what Marduk guessed was the centre of the structure.
He approached the central pyramid warily, weapons ready. It began to silently rise, green light spilling from beneath it. Whatever mechanism or sorcery lifted the massive weight was powerful indeed and the smooth black pyramid rose high into the air, steadily and silently. He realised that it was not a pyramid at all, but rather was an immense diamond shape, and he squinted against the green glare that spilled from beneath its bulk, his bolt pistol scanning for movement.
'The gateway to the ancients,' breathed Jarulek as he came up beside Marduk. There was nothing holding or supporting the giant, black diamond shape as it rose, neither above nor below. It lifted higher and higher into the vast empty space above them, hanging suspended in the air.
The Coryphaus entered the room, Burias at his side, and Marduk's eyes narrowed.
'We hold here. We are right where we are meant to be,' ordered Jarulek.
With a nod, Kol Badar quickly ordered the Cult of the Anointed into positions around the edge of the circular dais, guarding the corridor entrances, forming a protective circle around the Dark Apostle, facing out. 'The shadow wraiths seem unable or unwilling to enter this room,' said Marduk.
The Dark Apostle made no response, his eyes fixed on the expanse vacated by the diamond that had come to a halt, hanging ten metres above them. The green light had dimmed and from the smooth, black sides of the angled hole that the diamond fitted perfectly into, wide steps appeared out of the seamless, black stone. A section of the black stone sank away and a gateway was revealed at the foot of the steps, green light spilling from the same sun and light-beam icon that had appeared on the outside of the pyramid.
There was a shout for silence from the Coryphaus, and Marduk ripped his eyes away from the newly exposed gateway. A dim, rhythmic and repetitive sound could be heard in the silence that followed, something akin to metal striking stone. He realised that it was getting louder and he turned around, trying to get a lock on where the sound was emanating from. It seemed to be coming from all around.
'What in the name of the true gods is that?' he said.
'Something comes,' hissed Burias.
He could see nothing at first, but then he saw green lights, eyes of the enemy, appearing within the darkness of one of the corridors, no, from
