Inside, all was darkness, but Delau's enhanced vision easily pierced the gloom. Shattered equipment and blackened metal lay strewn about, the walls peppered with grenade fragments. A body lay against one wall, the little flesh that remained on its skeleton was scorched and black. This body's face was blown away, and Delau remembered the two shots Honsou had fired to kill these men.

Where then was the body of the third?

As he scanned the deserted listening post, he saw the open footlocker and the discarded items that lay strewn about it. He fell to his knees, examining them all in turn. All were useless trinkets and, to a man trapped on the mountain, worthless.

So, one soldier had somehow survived and salvaged everything of value from the bunker.

Where had he gone?

Delau marched from the listening post and examined the dusty ground outside. The corpse on the ground had no rifle and Delau guessed that the survivor had taken it before moving on.

Delau sniffed the air and knelt beside the decaying corpse, noting a patch of discoloured rock beside its feet. Without needing to taste it, he knew it was blood and, from its patterning, that it had not come from the corpse's wound.

So Forrix was correct. There was someone still alive on the mountains. A resourceful man as well, if Delau's reasoning was correct.

Scanning the surrounding environment, he knew there was only one way a man determined to strike back at the Iron Warriors would have gone: north-west across the knifeback ridge to a position of observation.

Swiftly he gathered the indentured soldiery to him and set off up the mountainside.

Goran Delau grinned within his helmet at the thought of facing this worthy foe.

Hawke scrambled across a jagged outcrop of rock, breathing heavily as he traversed the steep slopes of the mountain. He had travelled three kilometres across exceptionally difficult terrain and had another two kilometres to go before nightfall, but he was determined to make it.

Despite the weary exhaustion filling his limbs, he was filled with real purpose. He pulled himself onto a relatively flat slab of rock and took a moment to get his breath back. He checked his location on the direction finder, knowing where he had been ordered to go, but not knowing exactly what he would find when he got there. Lieutenant Colonel Leonid himself had given him his mission on the vox earlier that day and Hawke had assured him that he would not let them down.

'You cannot,' Leonid had said, 'all our hopes rest upon you.'

Hawke had felt that was kind of melodramatic, but hadn't said so. He was too pleased by the fact that he was being trusted with something so important.

'Well, Hawke,' he chuckled to himself, 'It's a commission for you when you get back home.'

He mopped his brow with his sleeve and unwrapped one of his last ration packs, chewing on the remains of a high-energy bar. Hawke groaned as he pushed himself to his feet. He was amazed at how good he felt, despite not having taken any detox pills for over two weeks. He had become lean and his muscles, especially in his legs, had become well-defined. He smiled as he realised he was in better shape than he had been for years. His spreading midriff was gone and his lungs felt clearer than ever.

True, his food and water supplies were all but exhausted, but Lieutenant Colonel Leonid had assured him that they were working on that even now. He wolfed down the last of the food bar and tossed the wrapping aside as he squinted into the afternoon sun.

'Well, you ain't gonna get there just by standing here, Hawke,' he said, climbing further along the rockface.

Hawke set off again through the afternoon's heat.

Vauban and Leonid stood watching the rainbow flares of energy rippling above their heads, as enemy shell impacts slammed into the invisible energy field that protected the areas within the curtain wall.

Observers in the blockhouse on the northern slopes scanned the shield for breaches, as some shells were slipping through where coverage was incomplete, and detonating within the citadel's supposed safe areas. The warning they could give was probably too short to do any real good, but it was better than nothing and, once again, Vauban felt his anger mount towards Arch Magos Amaethon.

When the shells had first breached the shield he had spent an infuriating hour waiting to be hooked up with the Machine Temple on the holo-link. He knew he would be wasting his time attempting to see the arch magos in person.

'Why is the shield not holding?' he had demanded.

'It is… arduous work to maintain such a… a prodigious energy barrier,' explained the arch magos in stuttering, halting speech. 'To maintain all other systems at peak efficiency as well as the shield… requires great strength.'

'Then let the other systems go to hell,' raged Vauban. 'If you allow the shield to falter, then very soon there will be no other systems to maintain!'

'That cannot be,' snapped Amaethon as he shut off the link, and no matter how desperately Vauban petitioned the arch magos, he would not re-establish it.

Perhaps Naicin was right, perhaps it would be better for them all if Amaethon were to be got rid of. Indeed, Naicin had contacted him personally not long after his brief conversation with Amaethon and had insinuated that such an event might not be too hard to contrive.

Vauban pushed his thoughts of the damned arch magos and his scheming underlings from his mind, forcing himself to concentrate on the job in hand.

'Have you heard from Kristan and Anders yet?' he asked Leonid.

Leonid nodded. 'So far everything is proceeding as planned. Weapons, ammunition and demolition charges have been distributed to the soldiers taking part in the mission and the storming parties are gathering at the rally points.'

Vauban looked up into the crimson sky just as the day slipped from afternoon's warmth into evening's twilight. 'I wish it was already dark. I can't abide this waiting.'

'They say the waiting is the hardest part, sir.'

'And are they right, Mikhail?'

'No,' chuckled Leonid. 'Not by a long shot. Give me the waiting any day.'

Vauban checked his pocket chronometer and frowned. 'Any word from Hawke?'

'Not yet, sir, no, but we should give him time to get there.'

'He'd better get there soon or that magos you sequestered will be missed by his brethren and spill his guts. I'm keen to avoid that, at least until it is too late for them to interfere, Mikhail.'

'We should give Hawke a little more time, it's a tough journey,' pointed out Leonid.

'Do you think he can do it even if he does get there?'

'Yes, I think he can. His profile has him as above average intelligence, and he's come a long way from the disgrace of a man we once knew as Guardsman Hawke. He's a soldier now.'

'Any idea why he's not coughed up his lungs yet? He claims to have ran out of detox pills over a week ago.'

'Not yet, sir. I asked the Magos Biologis how long we could expect Hawke to keep going, but he was pretty vague, and claimed it wasn't possible to predict exactly.'

Vauban shook his head. 'Emperor preserve us from the meddling of the Adeptus Mechanicus.'

'Amen to that, sir,' agreed Leonid. 'What of our new arrivals? Are they in agreement with our plan?'

Vauban smiled, though there was no warmth in his expression. 'Oh yes, they are wholeheartedly with us.'

Leonid nodded, but said nothing, noting the way the castellan gripped the hilt of his power sword. Both officers were arrayed for battle and had taken pains to appear so for their men. Vauban had put on his dress uniform jacket and wore his silver breastplate over it, the bronze eagle at its centre polished to a brilliant sheen. Leonid's breastplate was bronze, but also gleaming. The dent in its centre where he had been shot had been repaired and the armour was as good as new.
