'I think you might have a hard time convincing some of the die-hards of that.'

'Not if they knew what I know,' said Cavalerio. 'But what say we dispense with the small talk and discuss the real reason for your visit?'

Sharaq nodded, circling the tank with the awe of one in the presence of greatness, and Cavalerio read his unease in his increased heart rate and spiking alpha waves.

'It's all right, Kel,' said Cavalerio. 'You don't need to feel guilty. You did what you had to do and I would have been disappointed if you hadn't.'

Sharaq stopped his circling and knelt before the casket, placing his hand on the warm glass of the tank. Cavalerio floated to the front, his flesh marbled and glossy, his features all but obscured by the complex bionics that grafted him to the machinery of his life-support. Only an inch of toughened glass separated the two men, but an anatomy's worth of augmetics created a gulf between their humanity.

'I don't feel guilty,' said Sharaq. 'I know I did the right thing. You weren't fit to command the Legio then and, despite your progress, I still don't think you're ready. Soon, but not yet.'

'Then why are you here?'

'I need your help, Stormlord,' said Sharaq, 'and I need your experience. I fear I am not cut from the same cloth as you. Leadership is in your blood, but not in mine.'

'Then speak,' ordered Cavalerio. 'I may not be Princeps Senioris, but I am still your friend.'

The words were meant to comfort Sharaq, but only seemed to wound him. He looked over at Agathe and said, 'Perhaps we might speak privately, my princeps?'

'Agathe is my famulous and anything you have to say to me can be said in front of her.'

'Very well, Stormlord,' said Sharaq. 'You won't have failed to notice that you haven't been linked to any ports with outside access during your recovery. The medicae felt it would hinder your adjustment for you to be inloaded with an excess of data.'

'A decision that, with hindsight, I applaud,' said Cavalerio. 'So tell me, what's been happening beyond our fortress? Have Mortis been taken to task for their violation of our territory?'

Sharaq shook his head. 'No, my lord,' he said, 'they have not. The Princeps Conciliatus have been appraised of the facts and they have issued a summons, but both the Fabricator General and Princeps Camulos ignore it.'

'A Conciliatus summons and a rift between the Legios? Ignored? Madness!'

'All of Mars may well have gone mad, my princeps,' agreed Sharaq.

'What do you mean?'

Sharaq shared a look with Agathe and said, 'The situation on Mars has deteriorated almost to the point of open warfare. Disaster strikes at the Mechanicum from all sides and we are petitioned daily for our engines to walk.'

'Petitioned by whom?'

'I have received missives from no less than seventeen forges, all begging us to initiate an execution. With your permission, my princeps, I should like to inload your casket with the latest updates on the current tactical situation.'

'Of course, Kel,' said Cavalerio. 'Immediately.'

Sharaq said nothing and didn't appear to move, but Cavalerio felt a rush of data as his fellow princeps noospherically unlocked the feeds that were part of the Martian network and which fed directly into the smart liquid of his casket.

'Blood of the Omnissiah,' hissed Cavalerio as the data permeated his mind via informational osmosis. In an instant, he drank in the terrible events of the Death of Innocence caused by the hateful scrapcode, the spate of catastrophic machine failures and the rising tide of violence erupting all across the surface of Mars.

He saw bloodshed as forges went to war and old feuds were re-ignited. He saw opportunistic territorial grabs, spiteful acts of vengeance and hungry snatches for a rival's knowledge. The drums of battle were beating all over Mars, stirring the bellicose hearts of man, and spurring the looming presence of civil war ever closer.

It saddened him to realise that, a race apart though they might be, the Mechanicum were just as prone to human foibles as their unmodified brethren.

'And this scrapcode attack came just as Mortis walked on Ascraeus Mons?'

'We caught the first spurts of it, I think,' said Sharaq. 'It was fragmentary and dispersed, and Zeth's noospheric upgrades saved us from getting hit as hard as some others, but Legio Fortidus and Legio Agravides are gone. Their reactors went critical and took their entire fortress and a good chunk of the Erebus Montes with them.'

Cavalerio digested the information without comment, though it grieved him to think of two allied Legios lost to so ignominious a fate. He reviewed the data he'd been fed impassively, sifting through the morass of contradictory communiques, orders, requests, petitions, demands and propaganda flying between the forges. Factions were already forming, fragile alliances drawn along the lines of the tired old Omnissiah schism.

Blurts of cant circled the planet, some demanding an end to the union of Mars and Terra, while others urged all Mars to cleave more tightly to the bosom of humanity's birth rock. Worse, much of it had gone off-world, spreading like a plague on departing ships or within astropathic visions cast across the void to the Mechanicum contingents accompanying the Expedition Fleets throughout the galaxy.

'What's all this talk of Horus Lupercal?' asked Cavalerio, reading the binary version of the first primarch's name time and time again. 'What does the Warmaster have to do with any of this?'

'We're not sure, my princeps,' said Sharaq. 'The factions advocating the split from Terra seem to be championing the Warmaster as their deliverer from the Emperor. It's hard to make much sense of it, their code is so corrupt it's little more than binary screams of the Warmaster's name.'

'Has word of this reached Terra?'

'The inter-system vox is erratic, but Adept Maximal has apparently made intermittent contact with the Council of Terra.'

'And what do they make of all this?'

'It sounds like they're as confused as us, my princeps,' said Sharaq, taking a deep breath before continuing. 'Something bad has happened in the Istvaan system, something to do with the Astartes, but we can't get any hard facts.'

'But what of Mars?' pressed Cavalerio, 'what do they say about Mars?'

'The Mechanicum is told to quell the unrest or the Legions will do it for them.'

The mag-lev made good time through the southern reaches of the Tharsis uplands, skirting the edge of the pallidus and passing through a number of storms of wind-blown particulate on its journey eastwards. Dalia found the sight of the billowing ash strangely uplifting, and spent hours watching the spiralling vortices streaming down the length of the carriages.

She watched the dust rolling on and on throughout the landscape and envied its freedom to roam, blown hither and thither without direction by the winds. Increasingly she felt as though her life was just like the mag-lev, travelling upon a fixed track, guided inexorably forward to an inevitable destination. The notion of free will and choice seemed alien and strange to her, as though her brain was merely responding to external stimuli and she had no choice but to obey.

They saw little of their fellow passengers during the journey, save for the occasional awkward passing in the corridors to and from the ablutions cubicles or food dispensers. Dalia recognised most of them as low-level adepts on errands for their masters, servitors on automatic reassignment or migrant labourers moving to another forge in the hope of securing work. Perhaps three hundred souls travelled with them, but no one paid them any mind, a fact for which Dalia was absurdly grateful.

The thrill of venturing beyond the boundaries of the forge had worn thin for their little group after a few hours, and they had fallen into the strange silence of travellers on a long journey with nothing to help pass the time. The prospect of seeing one of the otherworldly pallidus border towns had excited them, but even that had proven something of a letdown.
