cannon would be to sever its head or remove its heart.'

'Consider this, Zarha, for I am finished with standing here and posturing over Mechanicus banalities. The Master of the Forge was trained on Mars, under the guidance of the Machine Cult and in accordance with the most ancient oath between the Astartes and the Mechanicus. He reveres this weapon, and counts his role in its reawakening as the greatest honour of his life.'

'If he was true to our principles, he would not do this.'

'And if you were true to the Imperium, you would. Think on that, Zarha. We need this weapon.'

'The Lord of the Centurio Ordinatus is en route from Terra. If he arrives in time, and if his vessel can break the blockade, then there is a chance Helsreach will see

Oberon

deployed.

I

can give you no more support than that.'

'For now, that is all I need.'

I thought that would end it. Not end it

well,

by any means. But end it nevertheless.

Yet as I walk away, she calls me back.

'Stop for a moment. Answer me this one question: Why are you here, Grimaldus?'

I face her once more, this twisted, ancient creature in her coffin of fluids, watching me with machine-eyes.

'Clarify the question, Zarha. I do not believe you speak of this moment.'

She smiles. 'No.

I

do not. Why are you here, at Helsreach?'

Strange to be asked such a thing, and I see no reason to lie. Not to her.

'I am here because one who was brother to my dead master has sent me to die on this world. High Marshal Helbrecht demanded that one Templar commander stay to inspire the defence. He chose me.'

'Why you? Have you not asked yourself that question? Why did he choose you?'

'I do not know. All I know for certain, princeps, is that I am taking that cannon.'

'

find it

difficult to countenance,' Artarion said, 'that your plan actually worked.' The knights stood together on the wall, watching the enemy. The aliens were massing, forming into clusters and chaotic regiments. It still resembled a swarm of vermin more than anything else, Grimaldus thought, but he could make out distinct clan markings and the unity of tribal groups standing apart from others.

It would be dawn soon. Whether or not that was the signal the xenos were waiting for didn't matter. The flow of landers had fallen to a trickle, no more than one every hour now. The wastelands were already home to millions of orks. The attack would come today. The overwhelming force they needed to take the city was here.

'It has not worked yet,' Grimaldus replied. 'Ultimately, it comes down to what they will allow. We need their cooperation.' The Chaplain nodded to the gathering horde. 'If we do not have Mechanicus aid in reactivating the cannon, these alien dogs will already be gnawing on our bones within a handful of months.'

A cry went up from further down the wall. Few Guardsmen remained posted on the battlements, and those that were served mainly as sentries. Two more of them shouted, and the call was taken up along the entire northern wall. The general vox-channel came alive with eager voices. The city's siren once more began to wail.

Grimaldus said nothing at first. He watched the horde sweeping closer like a slow tide. What little order had been evident within the enemy's ranks was broken now, and in the sea of jagged metal and green flesh, scrap-tanks and wreck-Titans powered forward - the former dense with aliens clinging to their sides and howling, the latter shaking the wastelands with their waddling tread.

'I have heard it said,' Artarion noted, 'that the greenskins raise their Titans as idols to their strange, piggish gods.'

Priamus grunted. 'That would explain why they are so hideous. Look at that one. How can that be a god?'

He had a point. The wreck-Titan was an iron effigy of a corpulent alien, its distended belly used to house the arming chambers for the proliferation of cannons thrusting from its gut.

'I would laugh,' Nero said, 'if there weren't so many of them. They outnumber Invigilata's engines at a ratio of six-to-one. '

'I see bombers,' Cador noted, neither interested nor disinterested, merely stating a fact. A wing of ugly aircraft, over forty of them, rose from landing platforms hidden behind the landers of the main force. Grimaldus could hear their engines from here, labouring like a sick elder ascending the stairs.

'We should abandon the walls, brothers.' Nero turned to watch the last Guardsmen making their way down the ramps and ladders leading from the battlements. 'The Titans will be firing soon.'

'So will theirs,' Priamus smiled within his helm. 'And these mighty walls will be reduced to so much powder.'

At that moment, a squadron of fighters soared overheard - the sleek metal hulls of Barasath's Lightnings turned silver by the reflections of the rising sun.

'Now that is courage,' said Cador.

arasath had

argued long and hard for permission to make his first attack run. This was principally because anyone with even a vague grasp of tactics could see full well it would almost definitely be not only his first attack run, but also his last.

Colonel Sarren had been against it. Adjutant Tyro had been against it. Even the Emperor-damned dockmaster had been against it. Barasath was a patient man; he prided himself on tact and the willingness to deliberate being among his chief virtues, but to have to sit there and listen to a

civilian

complaining and questioning his tactical expertise was beyond galling.

'Won't we need your planes to protect the tankers still coming from the Valdez platforms?' the dockmaster, Maghernus, had asked. Barasath gave the man a feigned smile and a nod of acknowledgement.

'It is unlikely the orks have the presence of mind to seek to cut our supplies of fuel, and even if they have, they would need to take the long route around the city, and risk running out of fuel themselves long before they reached our shipping lanes over the ocean.'

'It is still not worth the risk,' Sarren said, shaking his head and seeking to conclude the matter.

'With all due respect,' he said, none of his inner turmoil showing through to his demeanour, 'This attack run offers us too much to merely dismiss out of hand.'
