Without orders needing to be issued, each squad of Ultramarines was already positioning itself correctly, and Uriel felt proud to be part of such an awesomely effective fighting machine.

  Chaplain Clausel took up position with his assault squad, warriors who went into battle with bulky jump packs fitted to their armour. These allowed them to take the fight to the enemy and descend upon them from the skies on wings of fire. They were Astartes of the highest calibre, warriors who excelled in the brutal whirlwind of close-quarters fighting. As ferocious as they were, assault troops were not mindless killers, but carefully chosen fighters with an innate understanding of the ebb and flow of battle.

  An Assault Marine knew when to smash the enemy with force, and when to withdraw.

  Clausel had said little to Uriel since his return from his Death Oath, and every now and then he would catch the Chaplain's stern, uncompromising glare upon him. Which, he supposed, was entirely fair. After all, this mission was as much to test Uriel's ability to command his warriors as it was to ensure that the hard-won peace was holding.

  Techmarine Harkus, detached from the command centre and incongruous in his red armour and hissing servo harness, ministered to the Thunderhawk, ensuring that the rough landing had not offended the aircraft's spirit. The black and white of the Icon Mechanicus stood out on Harkus's right shoulder guard, while the blue of the Ultramarines remained on his left. The sight of an Ultramarines warrior in armour that bore another's heraldry sat ill with Uriel, but the union of the Adeptus Astartes and the Mechanicus of Mars was an ancient one.

  Uriel set off towards the canyon ahead of him, as the Aquila lander lowered its internal compartment to the ground and Lord Winterbourne emerged, resplendent in his green frock coat, high boots, golden helmet and ebony walking cane. Growling and pulling urgently on their leashes were the two hound creatures that accompanied the colonel everywhere he went. Uriel had learned that they were called vorehounds, and their noses darted from side to side as they sniffed the wet rocks.

  Four Lavrentian storm-troopers, in gleaming golden breastplates and carrying bulky hellguns, shadowed their colonel, followed by a robed scribe with clicking quill-armatures and a glassy-eyed vox-servitor.

  'Uriel,' said Winterbourne, 'good of you to help out. My lads were itching for some action, but it would take us quite some time to get up here, what? You and your fancy gunship are a real boon.'

  'Happy to help, Lord Winterbourne.'

  'Nathaniel,' said Winterbourne automatically. 'Damned unusual business this.'

  'Yes,' agreed Uriel, enhancing the thermal imaging display of his visor to better penetrate the shadows of the mountain. 'Unusual and conspicuous.'

  'Seems to support your suspicions, does it not?'

  Uriel nodded. 'If you're going to attack someone, first knock out their communications.'

  Reports had come to the Ultramarines command centre of a system-wide failure in a great many of the planetary vox-networks. Such glitches in the system were common enough not to raise immediate suspicion, but the timing of such a failure immediately raised a red flag in Uriel's mind.

  The Kaliz Array was hundreds of years old, and the Adeptus Mechanicus and local technicians had their hands full maintaining its venerable generators and relays. It would take days for PDF units or Guard forces to reach Deep Canyon Six, the location the Adeptus Mechanicus had identified as the source of the initial system failures. Uriel had immediately offered the services of the Ultramarines.

  'So, how do you want to do this?' asked Winterbourne.

  'We go in expecting a fight,' said Uriel. 'We will take one approach down, you and your men will take the other. If there are any enemy units there, we destroy them and see what damage they have done.'

  'Simple. I like it,' said Winterbourne, fighting to hold the vorehounds at his side. 'Damn it! Germaine! Fynlae! Heel!'

  The beasts paid their master no heed, and continued to tug at their leashes, foam gathering at the corners of their mouths and their desperate barking echoing from the mountainside.

  'What is the matter with them?' asked Uriel.

  'Damned if I know,' cursed Winterbourne. 'Heel! Heel, I say!'

  With a final surge, the vorehounds broke free of Winterbourne's grip, and bounded across the rocks towards the nearest gully leading down into Deep Canyon Six. Uriel and Winterbourne set off after them, with the storm-troopers hot on their heels.

  It didn't take long to catch up to the hounds, one of which sniffed the ground and growled at the entrance to the gully. The three-legged beast circled a patch of rocks downhill, eagerly barking with feral hunger. Winterbourne caught up to his pets, and struck at their flanks with his walking cane.

  'Damned unruly beasts!' he shouted, gathering up their leashes and hauling their choke chains tight. 'No discipline, that's your problem. I ought to have you shot.'

  Uriel knelt by the ground the vorehounds had been sniffing, and ran his fingers over the slick rocks. His enhanced vision and auto-senses could already detect the lingering residue and aroma of an all too familiar substance.

  'Blood,' he said.

  'Human?' asked Winterbourne, and Uriel nodded. 'Yes, and no more than a day or so old.'

  'How do you know that?'

  'The smell's too fresh. Any longer and the rain would have washed away all traces of it. Your hounds aren't the only ones with sharp senses, Lord Winterbourne.'

  'That bodes ill,' said Winterbourne, handing the reins of his vorehounds to the vox-servitor, and drawing his sword, a magnificently fashioned sabre with a curved blade and a network of crystalline filaments worked along its length that crackled with fire.

  Uriel passed the word of what the hounds had discovered to his warriors, and there was a noticeable shift in the posture of the Ultramarines, each warrior now expecting battle instead of merely anticipating it.

  'I suggest you join your soldiers, Lord Winterbourne,' said Uriel. 'It is time to move out.'

  'Just so,' said Winterbourne, unsnapping the catch on the holster at his hip. The colonel of the Lavrentians drew his sidearm, a simple laspistol with a matt black finish. The weapon was standard issue and old, very old, but clearly well cared for. Uriel was surprised at the lack of ornamentation on the weapon, having seen many a colonel seek to impress with the ostentation of their battle gear.

  Winterbourne saw his look and smiled.

  'It was my father's pistol,' he explained. 'Got me through a few damned tight scrapes, let me tell you. I look after it, and it looks after me.'

  Uriel nodded to Winterbourne's storm-troopers and left the colonel to their care. He jogged over to his squad, and quickly ran through the pre-battle ritual of preparedness. Each warrior inspected the battle gear of one of his brothers, checking armour and weapons that had been checked thrice already, but which were checked again because that was the Ultramarines way.

  When the icons for each of his squad members flashed green on his visor, Uriel broadened his scope of view, seeing icons flashing to life for every warrior under his command. All were ready.

  Chaplain Clausel approached, and Uriel offered his hand.

  'Courage and honour, Chaplain Clausel,' he said.

  'Courage and honour, Captain Ventris,' replied Clausel, leaving Uriel's hand unshaken.

  'My warriors will go in through the gully,' said Uriel, masking his irritation at Clausel's manner. 'Your assault troops will await my signal to manoeuvre.'

  'Remember the teachings of the Codex,' said Clausel. 'It will guide you in all things.'

  'I will, Chaplain,' promised Uriel. 'You do not need to worry about me. Librarian Tigurius reminded me of my duty to the teachings of our primarch.'

  'Aye,' agreed Clausel. 'I'm sure he did, but Tigurius cannot see everything.'

  'What does that mean?'

  'It means he wanted you back within the ranks of the Ultramarines,' said Clausel, 'for his own reasons as much as for the good of the Chapter.'

  'You doubt me, Chaplain?' asked Uriel. 'My
honour is intact, my loyalty undoubted. The senior masters of the Chapter agreed on it.'

  'Not all of them,' said Clausel, turning away. 'Just know that I remain to be convinced that your return is a good thing. Fight well and you may yet persuade me that one who fights within the Great Eye can come back unchanged.'

  'I am not unchanged, Chaplain,' whispered Uriel as Clausel rejoined his warriors.

  Uriel put the grim Chaplain's words from his mind, and issued his orders. The Scouts would remain with the Thunderhawk while Uriel would lead one squad through the southern gully towards the base of the canyon. Lord Winterbourne and his storm-troopers would take the northern approach. Chaplain Clausel and his assault troops would climb to the top of the cliffs that overlooked the base of the canyon and await Uriel's order to deploy.

  Uriel drew his warriors close, Learchus at his side, and stared into the darkness of the gully that led down through a narrow cleft in the rocks to shadow. He remembered the last time he had travelled into these mountains with war in his heart.

  He and his warriors had dropped thousands of metres into a deep core mine, and had faced the Bringer of Darkness in a forgotten tomb built when the galaxy was young. Ario Barzano had died there, and Pasanius had lost his arm, a grievous wound that had brought him nothing but pain and punishment.

  A punishment that had seen Uriel go to war without his dearest friend.

  SIX

  A COLD WIND blew down from the east, the bite of a harsh Macragge winter easing up now that spring was breaking and the snows on the lower slopes were melting. The landing platforms sat near the foot of the mountains upon which Ptolemy's Library and the Sword Hall were built, the eastern winds an omen of changing times and good fortune.

  Uriel did not feel fortunate as he marched from the upper cloisters to a flight of marble steps that led down to where the 4th Company stood in ordered ranks before five Thunderhawk gunships. Steam rose from the edge of the platforms, the aircraft growling as the Techmarines feathered their engines. The banner held proudly aloft by Ancient Peleus flapped noisily in the wind.

  Over a hundred warriors in the dazzling blue of the Ultramarines stood as still as statues on the platform, their arms locked by their sides and their heads held high as they awaited the order to embark on this latest mission. The Chaplain, Techmarines, Apothecaries, artificers, drivers and pilots, and ancillary company staff had gathered for the official Company Commencement. Not since the 4th Company had deployed to Tarsis Ultra had its duly-appointed captain led it into action, and such a moment demanded recognition.

  Uriel had dreamed of this ever since he and Pasanius had been banished from Macragge, and now that it was here, he found that redemption tasted bitter. For this new beginning marked the first time he had been forced to leave a battle-brother behind.

  ESCORTED BY FOUR armed Vanguards, Pasanius had come to bid Uriel farewell in the company chapel the previous evening as he prepared to don the armour of Brother Amadon for the first time. Uriel was clad in a form-fitting under-suit, and was surrounded by four red-robed artisan-apprenta from the Armorium.

  Uriel had prepared his flesh with fasting, oils and physical exertion.

  His soul was steeled with reflection and speaking the catechisms of battle.

  He was ready to be clad in the armour of a Space Marine, and the apprenta recited binaric cants pleasing to the Machine-God as they applied sacred oils to the hard plugs that allowed the armour to interface with his body.

  The chapel was a long, vaulted space of silver stone, brightly lit with a dozen flaming brands and the glow from a rose window set high on the western wall. Firelight reflected from the walls, and from the burnished battle-plate that hung on a sturdy frame before a great statue that stood in the curved chancel. Rendered in polished bronze by the hand of Mellicae, the greatest warrior artificer of the Ultramarines, the towering form of Roboute Guilliman stared down at Uriel with eyes fashioned from sapphires the size of a Space Marine's fist.

  The Vanguards led Pasanius into the chapel with their weapons bared, and it broke Uriel's heart to see his friend so ignobly treated. The apprenta backed away from Uriel with their heads bowed as Pasanius halted before him, still dressed in the black chiton of the penitent. Like Uriel, he had been found free of corruption in flesh and soul, but, for the crime of failing to disclose the truth of his infected arm, he had been judged guilty of breaking the Chapter's Codes of Rectitude.

  'You can go,' Uriel told the warriors escorting Pasanius.

  'We are ordered to remain with the prisoner at all times,' said one of the Vanguards, a black-bladed sword held across his shoulder. 'He begins his sentence at sunset.'

  Each of the Vanguards was clad in armour forged by masters of their craft, decorated with gold and silver trims, and polished to a reflective finish. No two were alike, yet each warrior had earned the right to wear such armour on uncounted battlefields, through acts of valour that would be unbelievable were any save a warrior of the Ultramarines to relate them.

  'This man is a hero of courage and honour,' said Uriel. 'You will not address him as ''prisoner'' in my presence again. Is that understood?'

  'Yes, my lord,' said the Vanguard. 'Our orders come from Chaplain Cassius himself.'

  'I am sure Pasanius is not going to try and escape,' said Uriel dryly. 'Are you?'

  'No,' said Pasanius. 'I'm in enough trouble as it is without adding attempting to escape to my list of crimes.'

  For breaking the Codes of Rectitude, Pasanius had been sentenced to a hundred days in the Chapter cells and to endure exclusion from the ranks of the 4th Company for the time it took Macragge to orbit its sun. In addition, he had been reduced in rank from sergeant to battle-brother. To be kept apart from his brothers for even a day longer than necessary was a punishment as severe as any that could be meted out to a warrior of the Ultramarines.

  'We will wait for you outside, brother,' the Vanguard told Pasanius as they withdrew from the chapel.

  'I'm obliged to you, and I'll be with you directly,' Pasanius assured them as the heavy wooden doors of the company chapel closed behind the veteran warriors.

  'You'll want help with that,' said Pasanius, nodding towards the armour.

  'I have the apprenta from the Armorium,' said Uriel, indicating the robed acolytes who waited at the foot of the statute.

  'Apprenta?' scoffed Pasanius. 'What do artisans know about the wearing of battle plate? No, you need a brother warrior to fit you into that armour. It's only right and proper. After all, this is the nearest I'll get to power armour until you get back.'

  Uriel turned towards the apprenta and said, 'Leave us.'

  The robed acolytes bowed and made their way from the chapel of the 4th Company.

  'A hundred days,' said Uriel when they were alone. 'It's not right.'

  'Don't be soft,' chuckled Pasanius. 'I'll do a hundred days no problem; it's no more than I deserve. I lied to my brothers, and more importantly, I lied to you. It's a just punishment. You and I both know it, and I'm not going to complain about it.'

  'You're right, I know,' said Uriel. 'You'll be missed within the ranks.'

  'I know,' said Pasanius without arrogance, 'but you've good men there as sergeants. Venasus, Patrean… Learchus.'

  'I've heard good things about Learchus from the men,' said Uriel. 'You read the honour rolls after the 4th's deployment to Espandor?'

  'I did,' confirmed Pasanius, kneeling to remove the first section of the armour from the rack. 'A gargant and a greenskin horde. Not bad.'

  Uriel laughed at the understatement in his friend's tone. 'It was a grand achievement, Pasanius, as you well know.'

  'Yes, but it galls me we weren't there for it,' said Pasanius. 'It feels wrong, knowing our warriors went into battle without us. It feels like we let them down.'

  'We did, but the past is done with, and I have a company to lead. When this expedition to Pavonis is over, you'll be reinstated to the ranks, and we'll fight side by side once more.'

 
'I know that, Uriel,' said Pasanius. 'Just…'

  'Just what?' asked Uriel when Pasanius didn't continue.

  Pasanius looked uncomfortable, and glanced towards the sealed doors of the chapel.

  'Come on,' pressed Uriel. 'Out with it.'

  'It's Learchus.'

  'What about him?'

  'Watch him.'

  'Watch him?' said Uriel. 'Why? Because his accusations saw us condemned? You know he was entirely correct to speak up.'

  'Yes, and I hold no grudge against Learchus for that,' said Pasanius. 'It took courage for him to do the right thing, I see that now.'

  'Then what?'

  Pasanius sighed. 'Learchus promised he would look after the company until our return, and by the looks of things he's done a grand job: fine recruits, hard training and warriors we can be proud of. Not only that, he led them all into battle on Espandor against a horde of greenskins that would have tested the mettle of a veteran battle company.'

  'Then what troubles you?'

  'No one expected us to come back alive, Uriel,' said Pasanius. 'Learchus was one of the few who did, but even he had begun to believe us dead. On Espandor, he got a taste of proper command and he liked it. I'm thinking that with us long gone, he figured he'd be the logical choice to take command of the 4th.'

  'And then we returned,' finished Uriel.

  'Exactly,' said Pasanius. 'Now don't get me wrong, Learchus is a great warrior and I trust him with my life, but he'd be less than human if there wasn't some part of him that didn't resent your reinstatement.'

  'I think you are wrong, my friend,' said Uriel.

  Pasanius shrugged. 'I hope so, but enough talk, let's get this armour on, eh?'

  Uriel nodded, and, piece by piece, Pasanius clad him in the armour of Brother Amadon. He began with the boots, and worked up to the greaves on Uriel's shins and the cuisse plates protecting his thighs. The locking belt snapped together around Uriel's hips, and, once the power coils were attached, Pasanius reverently lifted the eagle and skull-stamped breastplate and fitted it over his chest.
