Abaddon put his hand to the hilt of his sword and growled.
‘Your duplicitous nature is well known,’ said the captain, teeth bared in anger. ‘The Warmaster saw fit to bring you into the light of his plans, I hope you have not made a mockery of his fair judgement.’
‘I seek to place Horus on the throne of Terra, the same as you,’ replied Alpharius, lowering to one knee in deference. It was an instinctive reaction, though such submission grated at the primarch’s pride. ‘If I acted out of turn it is only because circumstance forced me to make a decision quickly.’
‘I have not yet heard an explanation for your actions,’ said Horus.
The Warmaster’s gaze was piercing, as if trying to bore into the primarch’s mind to see his thoughts. Alpharius matched the stare without fear. Horus knew nothing of the Alpha Legion’s true aims. If he had any inkling of the part made out for him by the Cabal, Alpharius would already be dead. ‘I consider it a grave crime to usurp my authority, a crime compounded by the severity of the consequences.’
‘The Raven Guard have not yet been apprehended,’ said Erebus, a sneer twisting his lips. ‘Though but a shadow of their former strength, it was foolish to allow them to escape.’
‘You must trust me,’ said Alpharius, ignoring the two legionaries, his attention focused on his brother primarch. It was the Warmaster’s will, or whim, that needed to be swayed to Alpharius’s cause. ‘The military potential of the Raven Guard has been expended, they are no physical threat. Their survival, Corax’s escape, will play a greater role in this war we have unleashed.’
‘Will it?’ Abaddon spat the words, his scorn etched into the creases in his brow. ‘What greater role?’
Alpharius kept his gaze on the Warmaster, noting that his displeasure did not seem so deep. It was clear that he did not have Horus’s full trust, but Alpharius did not care for that. His brothers had always been wary of the Alpha Legion, always suspicious of their methods, if not their motives. Horus was no different. He had consistently underestimated the power of subterfuge, eschewing the subtler weapons of espionage and misdirection in favour of overt action. Alpharius had not answered the Warmaster’s summons to excuse his actions, he had come to persuade Horus of their merit. That he could do so without the interference of the other Legion commanders was an advantage.
‘The Alpha Legion have infiltrated the Raven Guard,’ Alpharius said bluntly.
He saw Horus’s eyes widen slightly with surprise, and suppressed an expression of pleasure at the Warmaster’s nonplussed moment. Far from an admission of guilt, it was a declaration of strength; the unveiling of a weapon that the Alpha Legion kept hidden.
Alpharius could see the calculation behind the Warmaster’s eyes. If the Alpha Legion could infiltrate the Raven Guard, they could have done the same to any Legion. The Warmaster cocked his head to one side, momentarily perturbed, his eyes flicking away from Alpharius for the first time since he had entered, glancing at Abaddon.
‘To what purpose?’ asked Horus, recovering his composure, his stare returning to its previous intensity. ‘Had they been destroyed, what would be the point of spying on corpses?’
‘You allowed Corax to get away from the World Eaters to protect your operatives.’ Erebus levelled the accusation with a pointed finger, pushing Alpharius’s patience beyond its limit.
‘I am a primarch, genetor of the Alpha Legion, and you will show me due respect!’ snapped Alpharius, standing up.
He took two steps towards Erebus, eyes glittering. Abaddon moved to intercept him, half-drawing his blade.
‘Don’t make the mistake of letting that sword leave its scabbard,’ said Alpharius, fixing Abaddon with a venomous glare. ‘I may prefer to work in subtle ways, but if you continue to insult me, I will slay you here and now.’
Horus held out a hand, waving Abaddon back, a thin smile on the Warmaster’s face. He seemed pleased at Alpharius’s anger. ‘You are somewhat defensive, my brother,’ he said, gesturing for Alpharius to seat himself on one of the chairs arranged around the throne. ‘Please explain to me the benefits of allowing Corax to escape.’
Alpharius sat down, reluctantly accepting the Warmaster’s invitation, darting a warning look at Erebus just as the Word Bearer opened his mouth to speak.
‘Save your posturing for those that are swayed by it,’ said Alpharius. ‘Your change of loyalty proves the vacuity of your proselytising. You are privileged to stand in the presence of your betters, and should know not to speak until spoken to.’
The primarch enjoyed the contortions of anger that wracked the First Chaplain’s face, but Erebus heeded the warning and said nothing.
‘I have good information that Corax will attempt to return to Terra,’ Alpharius said, turning his attention back to Horus. ‘He will entreat the aid of the Emperor, and be given access to some secret of Old Night that we can use to our advantage.’
‘From where does this “good information” come?’ asked Horus, affecting disinterest though Alpharius could see that the Warmaster was intrigued.
‘We each have our own means and sources,’ replied Alpharius, flicking a meaningful gaze towards Erebus. The Alpha Legion had made it their business to know as much as possible about their fellow conspirators, and Alpharius was well aware of the strange rituals that Lorgar and his Word Bearers now indulged in. The Alpha Legion’s allies in the Cabal had furnished them with much information concerning the Primordial Annihilator, the Power of Chaos. It would not hurt to pretend that the Word Bearers were not the only Legion who had influence with the powers of the warp. ‘I am not of a mind to share mine with you at the moment.’
‘Are you not?’ said Horus, irritated. ‘Why would you keep secrets from me?’
‘Perhaps it is just my nature to do so. Secrecy is my best weapon.’ Alpharius smiled apologetically and gave a slight shrug. ‘Also, I do not believe myself or my Legion indispensable in your endeavours, so it would be unwise to surrender the few small advantages I possess. I know that my behaviour in the past and in recent times does not engender trust, but I assure you that this information is not only legitimate, but accurate.’
‘I will accept your assurances,’ said Horus, ‘for the moment.’ He leaned back in his throne, visibly relaxing as if to back up his words. Alpharius knew not to be lured into a sense of security. The Warmaster’s temper might change at a wrong answer from him or a sly word from Erebus. ‘What is your intent?’
‘We will allow Corax to obtain whatever it is he seeks, and then take it from him, turning it to our purpose.’
‘How do you think your operatives will remain undetected?’ Abaddon asked. ‘Our reports show that less than four thousand Raven Guard fled from Angron. New faces will be easily spotted, your legionaries exposed.’
‘That is why they wear old faces,’ Alpharius told him. He smiled and explained further when the others’ frowns deepened. ‘The Raven Guard were scattered as they fled the massacre at the dropsite. It was several days before they convened their strength again, during which time many were cut down in pursuit and anarchy reigned through their organisation. It was no simple matter for my Apothecaries to transplant the facial features of several fallen Raven Guard onto volunteers from my Legion, but they have had a lot of practice. As you may have heard, such facial surgery is not uncommon in the ranks of the Alpha Legion. My warriors are skilled and experienced, able to blend in without attracting attention. Even now they are with the Raven Guard, waiting for the opportunity to report.’
‘You stole their faces?’ Abaddon’s expression was a mixture of incredulity and disgust.
Alpharius nodded and looked for Horus’s reaction. For a moment the Warmaster had the same guarded look as earlier, but his aggression swept it aside as he leaned forwards, brow furrowing.
‘You are sure of their success?’ asked Horus, the words laden with accusation. ‘You have heard from them since they began their infiltration?’
