The majestic Lord of the Blood Angels, the IX Legion Astartes, stepped back, and looked out across the forlorn landscape. Around the base of the ragged hill, hundreds of armoured figures waited in silence. The vast majority wore either the hard white of the Luna Wolves or the arterial red of the Angels, save for the remnants of the detachment of Emperor's Children, a small knot of purple and gold. Behind the Astartes, the war machines waited in the rain, silent and black, ringing the gathering like spectral mourners. Beyond them, the hosts of the Imperial army stood in observance, banners flapping sluggishly in the cold breeze. Their armoured vehicles and troop carriers were drawn up in echelon, and many of the soldiers had clambered up to stand on the hulls to get a better view of the proceedings.

Torgaddon's speartip had razed a large sector of the landscape, demolishing stone trees wherever they could be found, and thus taming the formidable weather in this part of Murder. The sky had faded to a mottled powder-grey, ran through with thin white bars of cloud, and rain fell softly and persistently, reducing visibility in the distances to a foggy blur. At the Warmaster's command, the main force of the assembled Imperial ships had made planetfall in the comparative safely of the storm-free zone.

'In the old philosophies of Terra.’ Sanguinius said, 'so I have read, vengeance was seen as a weak motive and a flaw of the spirit. It is hard for me to feel so noble today. I would cleanse this rock in the memory of my lost brothers, and their kin who died trying to save them.’

The Angel looked at his primarch brother. 'But that is not necessary. Vengeance is not necessary. There is xenos here, implacable alien menace that rejects any civilised intercourse with mankind, and has greeted us with murder and murder alone. That suffices. As the Emperor, beloved by all, has taught us, since the start of our crusade, what is anathema to mankind must be dealt with directly to ensure the continued survival of the Imperium. Will you stand with me?'

We will murder Murder together.’ Horas replied.

ONCE THOSE WORDS were spoken, the Astartes went to war for six months. Supported by the army and the devices of the Mechanicum, they assaulted the bleak, shivering latitudes of the world called Murder, and laid waste the megarachnid.

It was a glorious war, in many ways, and not an easy one. No matter how many of them were slaughtered, the megarachnid did not cower or turn in retreat. It seemed as if they had no will, nor any spirit, to be broken. They came on and on, issuing forth from cracks and crevasses

in the ruddy land, day after day, set for further dispute. At times, it felt as if there was an endless reserve of them, as if unimaginably vast nests of them infested the mantle of the planet, or as if ceaseless subterranean factories manufactured more and yet more of them every day to replace the losses delivered by the Imperial forces. For their own part, no matter how many of them they slaughtered, the warriors of the Imperium did not come to underestimate the megarachnid. They were lethal and tough, and so numerous as to put a man out of countenance. The fiftieth beast I killed.’ Little Horns remarked at one stage, 'was as hard to overcome as the first.'

Loken, like many of the Luna Wolves present, personally rejoiced in the circumstances of the conflict, for it was the first time since his election as Warmaster that the commander had led them on the field. Early on, in the command habitent one rainy evening, the Mourni-val had gently tried to dissuade Horas from field operations. Abaddon had attempted, deftly, to portray the Warmaster's role and importance as a thing of a much higher consequence than martial engagement.

Am I not fit for it?' Horas had scowled, the rain dramming on the canopy overhead.

'I mean you are too precious for it, lord.’ Abaddon had countered. This is one world, one field of war. The Emperor has charged you with the concerns of all worlds and all fields. Your scope is-'

'Ezekyle...' The Warmaster's tone had betrayed a warning note, and he had switched to Cthonic, a clear sign his mind was on war and nothing else, '...do not presume to instruct me on my duties.’

'Lord, I would not!' Abaddon exclaimed immediately, with a respectful bow.

'Precious is the word.’ Aximand had put in quickly, coming to Abaddon's aid. If you were to be wounded, to fall even, it would-'

Horns rose, glaring. 'Now you deride my abilities as a warrior, little one? Have you grown soft since my ascendance?'

'No, my lord, no...'

Only Torgaddon, it seemed, had noticed the glimmer of amusement behind the Warmaster's pantomime of anger.

'We're only afraid you won't leave any glory for us,' he said.

Horus began to laugh. Realising he had been playing with them, the members of the Mournival began to laugh too. Horus cuffed Abaddon across the shoulder and pinched Aximand's cheek.

"We'll war this together, my sons,' he said. That is how 1 was made. If I had suspected, back at Ullanor, that the rank of Warmaster would require me to relinquish the glories of the field forever, I would not have accepted it. Someone else could have taken the honour. Guilleman or the Lion, perhaps. They ache for it, after all.'

More loud amusement followed. The laughter of Cthonians is dark and hard, but the laughter of Luna Wolves is a harder thing altogether.

Afterwards, Loken wondered if the Warmaster had not been using his sly political skills yet again. He had avoided the central issue entirely, and deflected their concerns with good humour and an appeal to their code as warriors. It was his way of telling them that, for all their good counsel, there were some matters on which his mind would not be swayed. Loken was sure that Sanguinius was the reason. Horus could not bring himself to stand by and watch his dearest brother go to war. Horus could not resist the temptation of fighting shoulder to shoulder with Sanguinius, as they had done in the old days.

Horus would not let himself be outshone, even by the one he loved most dearly.

To see them together on the battlefield was a heart-stopping thing. Two gods of war, raging at the head of a tide of red and white. Dozens of times, they accomplished victories in partnership on Murder that should, had what followed been any different, become deeds as lauded and immortal as Ullanor or any other great triumph.

Indeed the war as a whole produced many extraordinary feats that posterity ought to have celebrated, especially now the remembrancers were amongst them.

Like all her kind, Mersadie Oliton was not permitted to descend to the surface with the fighting echelons, but she absorbed every detail transmitted back from the surface, the daily ebb and flow of the brutal warfare, the losses and the gains. When, periodically, Loken returned with his company to the flagship to rest, repair and re-arm, she quizzed him furiously, and made him describe all he had seen. Horus and Sanguinius, side by side, was what interested her the most, but she was captivated by all his accounts.

Many battles had been vast, pitched affairs, where thousands of Astartes led tens of thousands of army troopers against endless files of the megarachnid. Loken struggled to find the language to describe it, and sometimes felt himself, foolishly, borrowing lurid turns of phrase he had picked up from The Chronicles of Ursh. He told her of the great things he had witnessed, the particular moments. How Luc Sedirae had led his company against a formation of megarachnid twenty-five deep and one hundred across, and splintered it in under half an hour. How Sacrus Carminus, Captain of the Blood Angels Third Company, had held the line against a buzzing host of winged clades through one long, hideous afternoon. How Iacton Qruze, despite his stubborn, tiresome ways, had broken the back of a surprise megarachnid assault, and proved there was mettle in
