Dorn continued. We left my brother, Horns, intent on making that voyage at long last, only to once more find the universe conspiring against us.'

Garro failed to keep a glimmer of unease from his face at the mention of the Warmaster's name, and he was aware that Sigismund noticed it. Garro knew from talk aboard the Endurance that the Imperial Fists had departed the 63rd Fleet some time before the Death Guard had arrived from the jorgall assault mission. In his years in the Legion, he had never shared the battlefield with the sons of Dorn and knew of them only by their standing with the other Legions.

Fierce warriors and masters of siegecraft, it was said that the Imperial Fists could hold any citadel and make it impregnable beyond the reach of any enemy. Garro had seen their work first-hand, in the design of

fortresses built on Helica and Zofor's World. What he had heard of them appeared to be accurate. Dorn and his men seemed as rigid as castle walls.

'The storms,' ventured Nathaniel. 'They almost claimed our lives.'

Sigismund nodded. 'If you will permit me to comment, lord, I have never seen the like. The tempest came upon us the moment we took to the empyrean, and it rendered the careful routes of our Navigators useless. Whatever waypoints we had turned to sand and disintegrated. The finest of the Navis Nobilite, and they were reduced to the level of blind children flailing in a featureless desert.'

Dorn stepped away from the window. 'This is how we came to find you, Garro. The storms ringed us in a disordered region of the warp, put us in the maddening stillness of their eye. The Phalanx and her fleet were becalmed. Every ship we attempted to send beyond the storms was torn apart.' A tiny flicker of grim irony crossed the primarch's face. 'The imma-terium besieged us.'

'You saw his flare,' said Qruze. 'Across all that distance, and you saw it?'

'A bold risk/ allowed the primarch. 'You could not have known that there would be anyone within range to glimpse it.'

'I had faith/ Garro replied.

Dorn studied him for a long moment, as if he were going to question the captain's words, but instead continued on. 'The Shockwave from the detonations of the drives disrupted the patterns of the storm barrier. The energy of the flare allowed our Navigators to get their bearings once more.' He inclined his head. We owe you a debt, Death Guard. You may consider it repaid by our rescue of your ship's crew.'

'My thanks, my lord.' Garro felt his gut tighten. 'My only wish is that the events that brought us to this place had not come to pass.'

'You pre-empt my questions, Garro. Now you understand how I came to your aid, it is your turn to illuminate me. I would have you explain why a lone Death Guard warship found itself in the uncharted territories, why signs of battle against Imperial guns lay upon her, and why one of your battle-brothers lies in my infirmary wracked by an illness that confounds the very best of my Legion's Apothecaries.'

Garro threw a look at Qruze for support and the veteran nodded back to him. 'Lord Dorn, what I have to say will not sit well with you, and at the end of the telling you may wish that you had not asked for it.'

'Oh?' The primarch moved to the middle of the sanctorum chamber, bidding them to follow. 'You think you know better than I what will distress me? Perhaps my brother, Mortarion, allows such presumption among the Death Guard, but that is not the manner of the Imperial Fists. You will give me the complete truth and you will excise nothing. Then, before my fleet makes space for Terra, I will decide how to deal with you, and the rest of your seventy errant Astartes.'

Not once did Dorn raise his voice or show even the slightest fraction of aggression behind his orders, yet the commands came with such quiet force that Garro found them impossible to resist. He was aware that Sigismund and a cohort of his men were at the edges of the chamber, watching him and Cruze for any signs of behaviour that might mark them as untrustworthy. Very well, my lord/ he replied.

Garro took a deep breath, and began the story at Isstvan and the Lupercal's Court.

ON ANY OTHER occasion, Qruze might have been willing to let his talkative manner come to the fore and lend his own viewpoint to a story told by one of his fellow Astartes, but as the lad Garro began to unfold the events to Dorn and his men, Qruze found himself quieted. He searched inside himself and realised there was nothing he could add to the Death Guard's dry, careful explanations, just a nod now and then when Garro looked to him for confirmation of some minor point.

The Luna Wolf became aware of the silence that had fallen across the rest of the sanctorum chamber. Sigismund and the other Imperial Fists in the black-trimmed armour of the First Company were as still as statues, their faces stoic against the unfolding tale. Rogal Dorn was the only point of motion in the room, the primarch walking back and forth in a slow pattern, lost in thought, occasionally pausing to stop and give Garro his full, unwavering attention. It was not until Garro reached the moment of Eidolon's orders to kill Saul Tarvitz and his refusal to obey that Dorn spoke again.

You disobeyed a ranking officer's direct command.' It was not a question.

'I did.'

'What evidence did you have at that time that Tarvitz was not, as Eidolon said, a renegade and a turncoat?'

Garro hesitated, shifting uncomfortably on his aug-metic leg. 'None, lord, only my faith in my honour brother.'

'That word again,' said the primarch. 'Continue, captain.'

Qruze had heard second-hand from conversations with Sergeant Hakur of the firefight on the Eisenstein's gun deck, but it was only as Garro relayed it that he found a true sense of it. The Death Guard baulked at repeating the seditious declarations of Commander Grulgor, and when Dorn ordered him to, a new tension emerged across the room as he finally gave voice to them. Qruze saw anger pushing at Sigismund's lips and finally the captain spoke.

'I cannot hear this without answer! If this is true, then tell me how the Warmaster allowed Death Guard and Emperor's Children alike to make these plays for power under his very nose? The unsanctioned virus bombardment of an entire world? The execution of civilians? How did he become so blind overnight, Garro?'

'He was not blind/ Garro said grimly. 'Horus sees only too well.' He looked the primarch in the eye. 'Lord, your brother is not ignorant of this duplicity. He is the author of it, and his hands are stained with the blood of men from his own Legion, from mine and from those of the World Eaters and the Emperor's Children as well-'

Dorn moved so quickly that Qruze flinched, but the Master of the Imperial Fists was not coming for him. There was a crack of sound and Garro fell away, skidding back across the bright blue marble of the sanctorum's flooring. Qruze saw Garro hover on the edge of unconsciousness, a livid bruise forming on his face. With care, the Death Guard blinked back to wakefulness and worked at resetting his jawbone.

'For even daring to think of such a thing in my presence, I should have you flogged and then vented to the void/ growled the primarch, every word a razor. 'I will not hear any more of this fantasy'

'You must/ Qruze blurted, taking a half-step forward. He ignored the ratcheting of slides on the bolters of Sigismund's men. 'You must hear him out!'

'You dare to give me an order?' Dorn faced the old warrior. 'A relic who should have been retired centuries ago, you dare to do so?'

Iacton saw his opening and took it. 'I do, and furthermore I know that you will. If you truly thought that Garro's words had no value then you would have killed him where he stood.' He moved to help Garro to his feet. 'Even in your moment of anger, you pulled a blow that could have broken his neck... because you want to hear everything. That is what you asked for, isn't it? The complete truth.'
