Mike Lee - Fallen Angels

He blinked, trying to clear his eyes, and found Lord Cypher studying him speculatively. Before Zahariel could ask what he was staring at, the enigmatic Astartes abruptly turned away.

They descended into darkness, lit only by feeble red emergency lighting inside the maintenance lift's metal cage. Hadziel had authorised the activation of a bank of four lifts that would allow Luther's four assault squads to deploy together, concentrating their strength against whatever foes awaited them. Based on their experience at Sigma Five-One-Seven, Zahariel had advised choosing the set of lifts in the closest proximity to the arcology's main thermal core.

The strength of the maelstrom increased steadily the deeper they went, until Zahariel scarcely had to focus his awareness in order to sense it. The unnatural energies sank effortlessly through his armour and pulsed sickeningly against his skin. Frost coated the housing of his psychic hood and sent needles of icy feedback into his brain. The storm winds tugged ruthlessly at him, tearing at his mind and soul with increasing vigour.

Finally the lift jerked roughly to a halt, two hundred metres below the earth. They'd reached the lowest sub-level of the arcology. Luther gave a nod to the Astartes manning the controls, and the lift doors clattered open, revealing a broad, low-ceilinged chamber formed of fused permacrete. The air was stiflingly humid and thick with the stench of corruption.

Here, as with the lower levels at Sigma Five-One-Seven, the earth had already begun to reclaim the space. Glossy greenish-black vines sprouted from cracks in the walls and along the floor, and a dripping, greenish mould covered much of the ceiling. Inserts chittered and squirmed through the tainted growth, or droned through the thick air on blurring wings. Sickly blue luminescence radiated from colonies of fungus that sprouted in haphazard clusters overhead, providing ample light to the Astartes' enhanced night vision.

The Dark Angel squads deployed swiftly from the adjoining lifts. Three assault squads took the lead, forming a protective arc in front of Luther and the command squad, and orienting their weapons on the three entryways on the opposite side of the chamber. Two men in each of the assault squads carried a hand flamer, while two of the veterans in Luther's command squad were armed with powerful, short range meltaguns. The rest carried roaring chainswords and blunt-nosed bolt pistols, ideal for the kind of close-quarters fighting they expected to encounter. They were forty strong, a fearsome display of force. Entire worlds had been brought into compliance with less.

Luther led the command squad into the chamber. His huge sword Nightfall burned a fierce blue in his right hand, and his ornate bolt pistol gleamed dully in his left. Zahariel stood next to him, clutching his force staff with both hands, while Brother Attias and Lord Cypher brought up the rear. Cypher held his plasma pistol ready in his right hand. The leather-bound grimoire was clutched tightly against his chest.

The Master of Caliban leaned close to Zahariel. 'Can you sense the ritual in process?' he asked quietly.

Gritting his teeth, Zahariel focused his awareness through the psychic hood. The dampener was already straining at the limit of its abilities; he could smell the strange mix of overheated circuitry and frozen metal. This close, he could sense rhythms pulsing through the howling psychic wind, like discordant notes struck by a madman's hand. The vibrations represented the symbolic chants that coaxed the energies of the warp into the physical realm.

'The ritual is well advanced,' the Librarian said, suppressing a groan of disgust. 'It could reach its climax at any time. We have to hurry!'

Luther nodded. His dark eyes shone with fevered intensity. 'Listen, Zahariel. When we reach the ritual site, I want you to keep close to me. We have to confront this entity, together. I have the knowledge, but I lack the ability to manipulate the forces of the warp.'

Zahariel shook his head. 'Confront it? You mean drive it back.'

'No,' Luther said. 'At least, not yet.' He turned and nodded at the grimoire that Cypher carried. 'That book contains the means to subjugate the spirit, bend it to our will. If we can reach it at the right moment, while it's still weak.'

'You can't be serious!' Zahariel cried. 'What you're talking about is madness! The Emperor—'

Luther stepped close, until he was nearly whispering in Zahariel's ear. 'Yes. The Emperor has forbidden this. Why? Because he fears the beings of the warp. That's something we must learn to exploit, if Caliban is to remain free.' He looked deeply into Zahariel's eyes. 'Do you trust me, brother?'

Zahariel found himself nodding, despite the misgivings in his heart. 'Yes. Of course.'

'Then help me. It's the only way.'

Without waiting to hear Zahariel's reply, Luther turned and waved the assault squads towards the rightmost of the three large openings on the other side of the landing. So far, the path to the ritual site seemed to lead to the arcology's primary thermal core, just as it had at Sigma Five-One-Seven. With a pair of flamer-wielding Astartes in the lead, the first assault squad advanced into the broad, vine-choked passageway. Luther's command squad was third in line, with the last assault squad covering the rear.

The corpses came at them from three sides. A few hundred metres down the passageway, it was bisected by another pair of wide corridors. The enemy, showing a rudimentary grasp of tactics, allowed the first and second squads to pass this junction before triggering their ambush. With scarcely a sound, hundreds of rotting corpses shambled out of the darkness, attacking the head of the advancing strike force and trying to drive into its midst from either side.

Flamers hissed, filling the passageways with streams of searing promethium. Bolt pistols barked on every side, felling the advancing creatures with well-placed shots to the head. The Astartes continued to fire even as the corpses surrounded them, drawing into arm's reach and trying to drag down the armoured warriors by sheer weight of numbers. Chainswords roared and slashed, severing limbs and splitting torsos.

The Dark Angels stood shoulder to shoulder in the confined space, never yielding a centimetre to the unearthly horde. At the centre of the formation, standing at the junction of the passageways, Luther roared encouragement to his warriors and put down one corpse after another with his pistol. Zahariel and Attias joined in with their own pistols, adding to the whirlwind of steel that took a fearful toll of the enemy.

For several long minutes the battle raged against the walking dead. The corpses pressed harder and harder against the Astartes - and then, inevitably, the pressure began to wane. The strike force, sensing that they had absorbed the brunt of the attack, began to press further down the passageway. Flamers continued to hiss and spit, until the walls of the passage shimmered with heat and the air grew thick with smoke and the stench of burnt meat.

Zahariel followed Luther through a waking nightmare. They advanced in the wake of the lead assault squads, moving down a tunnel of burning vines and shredded bodies. The slaughter was incredible; within only a hundred metres the Librarian found himself walking on a literal carpet of broken bodies. In places his boots sank into piles of blood and bone that rose nearly to his knees.

The Astartes drove inexorably forward, grinding the enemy beneath their heel. Then, without warning, the passageway widened into a huge chamber that crackled with unnatural energies. They had reached the thermal core.

Blasting their way through a faltering rear guard of corpses, the first and second assault squads broke through into the chamber far enough to make room for Luther's command squad. Then they halted, weapons ready, waiting for word from their commander.
