'Learn from him? Nothing,' said Uriel, tiring of Tigurius constantly meeting his answers with further questions.

  'Are you sure?' asked Tigurius. 'If not from his words, then by his poor example.'

  Uriel thought back to Medrengard, though the memories were painful and unpleasant. The renegade Space Marines he and Pasanius fought alongside had, for a brief, shining moment, embraced their cause and journeyed into the heart of the Iron Warriors' citadel. But Ardaric Vaanes had, in the end, forsaken them, and left them to their fate.

  Suddenly, it was clear to Uriel.

  'Vaanes's fate could have been my fate,' he said, with the growing confidence of epiphany. 'He let ego blind him to his duty and shared brotherhood. He believed he knew better than the teachings of his Chapter.'

  'Ardaric Vaanes is a classic example of a fate that can overcome even the best of us if we are not vigilant,' said Tigurius, and Uriel heard the warning in the Librarian's tone. 'Every one of us constructs self-enhancing images of ourselves that make us feel special, never ordinary, and always of greater stature than we are. This is at the core of what makes a Space Marine such a fearsome opponent, the complete and utter belief in his ability to achieve victory no matter the odds against him. It boosts his courage, his self-esteem, and protects him from the psychological tribulations of being surrounded by death and forever immersed in battle. After all, every one of us thinks we are better than the average. Isn't that so?'

  Uriel nodded, though the admission was uncomfortable. 'Perhaps I once thought like that.'

  'I know I did,' admitted Pasanius sourly. 'There wasn't a task I delegated that I didn't feel I'd have done better.'

  'As much as they help us, these egocentric biases can be maladaptive,' said Tigurius, 'blinding us to our failings and obscuring the awful truth that people exactly like us behave just as badly in certain evil situations. You assume that other people will fall to their vices, but not you, and do not armour your soul against temptations, believing that nothing bad can affect you, even when you know how easily it can happen.'

  Tigurius placed an open palm on the table, and bade Uriel and Pasanius approach.

  'When you were an aspirant and you learned of the Great Heresy against the Emperor, I imagine you concluded that you would not do what the forces of the Warmaster had done. You shook your head and wondered how anyone could have travelled such a road. Am I right?'

  Uriel nodded as Tigurius continued. 'Of course. I am sure you felt you simply could not have done what they did, but experience has shown that to be a lie, you can do such things. That belief is what makes us all vulnerable to such temptations, precisely because we think ourselves immune to them. Only when we recognise that every one of us is subject to forces beyond our control does humility take precedence over unfounded pride, and we can acknowledge our potential to tread the path of evil and engage in shameful acts. Tell me what that teaches you, Uriel.'

  'That in the right circumstances, any one of us can fall.'

  'Or the wrong circumstances,' added Pasanius.

  'I fell once, because I believed I couldn't,' said Uriel, 'but on Medrengard I saw where that path ultimately leads: degradation and damnation.'

  'Is that a fate you wish for?'

  'No,' said Uriel with utter finality, 'absolutely not.'

  'Then you have learned something of value,' said Tigurius.

  FOUR

  IMPERIAL COMMANDER AND System Governor of Pavonis, Koudelkar Shonai was not, at first, an impressive sight, with his soggy physique, weak chin and receding hairline. A warrior he was not, though, as Lortuen Perjed had come to learn in the last year, his appearance was deceptive and there was a clever mind and hard heart concealed behind Koudelkar's unimposing appearance.

  The second of two sons, it had been Koudelkar's brother, Dumak, who had been widely tipped to succeed Mykola Shonai as the next governor of Pavonis. However, Dumak had been slain by an assassin's bullet during one of the many worker riots in the days before Virgil de Valtos's attempted coup. In the wake of that rebellion, when Mykola Shonai's term of office was approaching its end, Lortuen had had swiftly groomed Koudelkar to take his aunt's place.

  It was a far from ideal situation, but as the senior adept of the Administratum on Pavonis, Lortuen had made the best of what was left to him. Most of the cartels were tainted with affiliations to traitors, and his masters had only accepted the scions of the Shonai as candidates for the role of Imperial Commander once they had agreed with his recommendation that no outsider be appointed to the position.

  It was a recommendation that Lortuen had come to regret many times, but his former master had been fond of saying that regrets were like weights; they were only a burden if you held on to them. Ario Barzano, Inquisitor of the Ordo Xenos, had been full of such aphorisms, but he had died at the hands of a malevolent eldar warrior beneath the northern mountains, depriving Lortuen of a thoughtful master and trusted friend.

  Since then, it had been a thankless task to restrain the policies of the young Shonai governor, whose idea of careful reconstruction was to aggressively pursue trade links with off-world conglomerates and merchant houses. With little infrastructure left in place, the planet's economy was fragile at best, but Koudelkar was not a man given to timidity, and the newly reconstructed palace was forever host to delegations from nearby systems, each seeking exclusive trading rights with Pavonis.

  It made for a heady, cosmopolitan atmosphere and had certainly brought revenue to Pavonis. None of which would be a problem were Lortuen not tasked with keeping track of the young governor's comings and goings. Appointed permanent Administratum observer to Pavonis after the rebellion, Lortuen was finding this assignment almost as exhausting as travelling the stars in service to an Imperial Inquisitor.

  Lortuen Perjed was not a young man anymore, his body aged well past the time when juvenat work would have done him any good. His mind was as sharp as ever, but his wrinkled flesh was liver-spotted, and even a brisk walk with his ivory-topped cane would tire him out. Had there been any justice, he would have been allowed to spend the rest of his days sequestered in some distant library with nothing but the study of dusty books and quiet contemplation to occupy his time.

  Lortuen closed his eyes and smiled at the prospect, but the sound of angry voices brought him back to reality with a jolt. He opened his eyes and swept his gaze around the governor's expansive meeting chamber.

  He sighed, realising that his dream of a quiet retirement was an ever more distant prospect.

  The Senate Chamber of Righteous Commerce was the heart of Pavonis's traditional governorship, but with the dismantling of the cartels' power it had fallen into disuse. In lieu of a formal debating chamber, Koudelkar Shonai had constructed a long, glass-panelled atrium in the heart of the Imperial palace from which to conduct his gubernatorial duties.

  Though open to the skies, thanks to rotating louvres in the curved roof, mast-borne voids secured the room from attack and wall-mounted vox-dampers prevented eavesdropping. Two gene-bulked skitarii in archaic-looking breastplates, hung with fetishes and carved with binaric oaths, provided more immediate protection for the governor.

  The skitarii had been a gift from High Magos Roxza Vaal, the highest-ranking Mechanicus adept of the Diacrian Belt, for the swift restoration of machine imports to the refinery belt of the south-east.

  Their swollen, bio-mechanical bodies and weapon implants were capable of immense violence, harking back to a barbarous age of gladiatorial combats, and truth be told, they scared Lortuen more than the Space Marines. You knew where you stood with the Adeptus Astartes, but these cybernetic monstrosities were a law unto themselves. Both were heavily scarred and tattooed, looking more like deep-sump hive-world gangers than guards appropriate for a Planetary Governor.

  A long, reflective table of polished wood from the fused remains of the Gresha Forest filled the centre of the room, and brass cogitators softly chattered along the entire length of one wall, with ticker-tape data-streams of
the sector markets fluctuations, raw material prices and system currencies.

  Liveried servants, for Koudelkar would not consider something as prosaic as servitors when there were men standing idle, stood holding silver ewers of wine with their heads bowed at the mirrored doors, ready to respond to their master's dictates.

  The meeting, requested by Lord Winterbourne of the 44th Lavrentians, started poorly when Clericus Fabricae Gaetan Baltazar pre-empted the order of business by immediately demanding that Governor Koudelkar have Prelate Culla arrested, or, at the very least, prevented from spreading his fiery rhetoric through the streets of Brandon Gate. As highest-ranking representative of the Adeptus Ministorum on Pavonis, Baltazar objected to the stirring up of the populace at a time when unity and rebuilding were the order of the day.

  Lord Winterbourne responded with a scathing remark concerning the insipid nature of the preachers within the walls of the Templum Fabricae, who seemed more inclined to preach a doctrine of introspection and quiet industry than the persecution of the Emperor's enemies.

  Lortuen sat to the right of Governor Koudelkar, who seemed content to let the two men vent their frustrations. Heated words passed back and forth between the Lavrentian colonel and the Clericus Fabricae, but Lortuen let the words wash over him as he accessed his augmetic memory coils to consult the data he held on the various luminaries attending the governor.

  The senior Imperial Guard commanders sat to the governor's left, formally clad in full dress uniforms, gleaming plumed helmets and scarlet capes. Lord Winterbourne had the lean, pinched look of a man used to campaigning, and Major Ornella faithfully transcribed the furious words passing between her colonel and the Ministorum priest.

  Across the table from Winterbourne, and on Lortuen's right, sat Colonel Loic, commander of the Brandon Gate PDF, who in deference to his commander in chief had come unarmed. Loic observed the argument with grim stoicism, and Lortuen knew that behind the purely political appointment, Adren Loic was a dependable, if unimaginative, soldier. Which, he recalled, accounted for his selection to the post.

  The ochre-robed Gaetan Baltazar sat beside Loic, resplendent in his chasuble and tall, gilded mitre. As he argued with Lord Winterbourne, Baltazar constantly worked prayer beads between his fingers.

  Beside the Ministorum priest, Jenna Sharben of the Brandon Gate enforcers sat with her hands clasped tightly before her. Lortuen liked Sharben. She had been Ario's guide in the days when he had been investigating the cartels, and had proved to be a resourceful, determined woman. It had been Lortuen's directive that had seen her begin the establishment of a new cadre of enforcers, and, looking at the sunken hollows beneath her eyes, he saw the strain that role was placing on her.

  As important and impressive as these individuals were, they were nothing compared to the dominating presence of the three Space Marines, who sat at the end of the table. Captain Uriel Ventris, a sergeant named Learchus, and a brutish warrior in gleaming black armour filled the room with their armoured bulk. The third warrior's helmet was worked in the form of a grinning skull, and his bellicose body language spoke volumes of his impatience and desire to be elsewhere.

  Lortuen had met Uriel and Learchus before, though the other warrior was unknown to him. As pleased as he was to see Captain Ventris, Lortuen was surprised at the change he saw in him.

  In Lortuen's time with Inquisitor Barzano, they had cause to fight alongside several Space Marines, many of whom had become staunch allies over the years. One facet that always amazed Lortuen was the apparent unchanging physicality of Space Marines. Though decades might pass between meetings, the genetic superiority of the Adeptus Astartes rendered them functionally ageless to the perceptions of most humans. Not so Uriel Ventris, who now carried hard-won wisdom in his eyes that spoke of horrors endured and lessons learned in blood.

  Lortuen knew that look; he had seen it in his master's eyes in the months before his death.

  Eventually, the argument between Winterbourne and Baltazar ended when Koudelkar slammed his palm down on the table.

  'Enough!' snapped Koudelkar. 'Your prattle is hurting my ears. I have better things to do with my time than listen to you two argue.'

  Gaetan Baltazar looked set to answer the governor's outburst with one of his own, but wisely kept his counsel, and simply nodded his head. Lord Winterbourne, clearly not used to anyone coming between him and a good argument, also bit his lip, and laced his hands together before him.

  'Thank you,' said Koudelkar, his tone more even and placating. 'We are reasonable men, are we not? I am sure that between you, this issue can be resolved. After all, we each wish for a secure, stable world where trade can flourish and the teachings of the Imperial Creed are heard by all.'

  'Of course,' said Baltazar, 'but all this predicant Culla preaches is hatred. He forgets the guidance and protection the Emperor represents. He fans the flames of fear, and that is not conducive to the stability you crave, my lord.'

  'Culla is a scrapper, and a damn fine one too,' said Winterbourne. 'I've seen him go toe to toe with greenskins, come out on top, covered in blood, and then go back for more. We're out on the Eastern Fringe, Baltazar, and in case you hadn't noticed, we're a long way from Terra. The only protection we can rely on are our guns, tanks and swords.'

  'Heresy!' spat Baltazar. 'The Emperor protects! A soldier like you should appreciate that.'

  'Oh, be quiet, man,' said Winterbourne. 'The Emperor indeed protects, but I don't expect Him to do it all for me. What you need is a good—'

  'Be silent!' barked the black-armoured Space Marine. His voice was deep and authoritative, a voice used to giving orders and having them obeyed without question. 'Did you not hear your commander? You should be ashamed of yourselves, arguing petty points of jurisdiction when you are gathered to discuss a deadly threat to your world. Captain Ventris?'

  The gathering was suddenly cowed, the skull-faced warrior's outburst silencing them all in an instant. Uriel Ventris nodded his thanks to the warrior and rose to his full height, which towered over the gathered officials, and even the two skitarii.

  Uriel folded his arms across his wide chest. 'Chaplain Clausel speaks bluntly, but he is right to do so.'

  'A deadly threat?' demanded Koudelkar, leaning forwards and steepling his hands before him on the table. 'To what does your comrade refer?'

  'There is a xenos presence on Pavonis, Governor Koudelkar,' said Uriel. 'Yet your senior officials argue and bicker while an enemy plans routes of invasion through your lands.'

  Lortuen's eyes widened at Uriel's statement, shocked that such a threat had only now come to light.

  'Are you sure?' he asked. 'We have seen nothing to suggest such a thing.'

  'Adept Perjed,' said Uriel with a nod of respect, and Lortuen was a clever enough orator to recognise that Uriel was pausing to gather his thoughts in the face of uncertain facts. 'We ambushed a forward reconnaissance unit of tau Pathfinders in the Owsen Hills recently. It is my belief that these aliens were scouting routes towards Brandon Gate, possibly for a larger force to advance along.'

  'Saints preserve us,' gasped Gaetan Baltazar, turning to the governor. 'We must mobilise all reserve units of the PDF, and deploy the 44th immediately!'

  Koudelkar held up a hand and took a deep breath before answering the dismayed Clericus Fabricae. 'Calm yourself, Baltazar. A full deployment of our armed forces would achieve little save to cause panic.'

  'If we are under attack, then—'

  'Do we appear to be under attack?' snapped Koudelkar, rapping his fingertips on the smooth surface of the table. 'If what Captain Ventris says is true, and these are merely scouts, then we have some time to formulate an appropriate response.'

  'An appropriate response would be to authorise a deployment of the 44th and to raise your alert level,' said Winterbourne. 'Then activate the Secondary and Tertiary Reserves.'

  Koudelkar shook his head. 'These are delicate times for Pavonis, Lord Winterbourne. I do not expect a fighting man like yoursel
f to understand the subtleties of planetary rule, but I am engaged in complex negotiations with several powerful subsector trading conglomerates to assure this planet's future prosperity. It would seriously jeopardise, if not utterly wreck, those negotiations were we to suddenly turn our world into an armed camp on the strength of one encounter with some easily bested aliens.'

  Lord Winterbourne bristled at Koudelkar's words, his spare frame shaking with anger.

  Uriel saw that anger and said, 'Governor Koudelkar, it would be a mistake to underestimate the tau. Their technology is highly advanced, and their warriors are skilful enemies.'

  'So I have heard, but I notice that you choose words that suggest you are not certain of your conclusion, Captain Ventris,' said Koudelkar. 'Aside from the presence of this one unit of aliens, what proof do you have of your suspicions?'

  'Nothing concrete,' said Uriel, 'but where Pathfinders are found, others are sure to follow.'

  'But you have seen no sign of any others?'

  'That is correct,' admitted Uriel.

  'Lord Winterbourne? Colonel Loic?' asked Lortuen, 'Have either of your forces discovered any sign of these aliens?'

  'We have not,' said Loic crisply. 'My long-range patrols have seen neither hide nor hair of any alien presence.'

  'Nor have mine,' said Winterbourne, in control of his anger now, 'but, my lord governor, I am inclined to agree with Captain Ventris. His Chapter has experience in fighting the tau, and if he believes there are alien forces on Pavonis, then I concur that we should prepare for battle.'

  'If the threat becomes credible, we will act upon it, I assure you,' said Koudelkar.

  'What will it take for it to become credible?' demanded Chaplain Clausel, and even Koudelkar flinched from his razor tone. 'A tau honour blade opening your throat? An enemy battle flag planted atop the palace?

  The governor composed himself in the face of the Chaplain's anger, and squared his shoulders. 'Would I be correct in assuming you killed all the tau you encountered?' he asked.
