'Half truths. Half truths and lies!'
'I... I don't understand...'
'Do you know what the Night Haunter's final words to me were? Do you know what he said, as he seated himself and awaited the assassin?'
'N-n—'
'He said "See how the mighty are fallen."'
'W-why?'
'Because he had finally realised what nobody else had ever seen. That his father, his glorious Emperor, his Divine Creator, was just as vicious, just as terrible, just as merciless, as the Night Lords themselves. See how the mighty are fallen. See how divinity lowers itself to dispose of the monster it created!'
One final pulse of rebellion — alone and drowning in a sea of doubt — struggled to be heard in Mita's heart. 'L-lowers itself? By sending an assassin? After all that Konrad Curze had done? After the horrors of the Heresy? What else could the Emperor have done?'
For an instant the doubt seemed to retract. For an instant she felt she'd somehow scored a point, landed a blow.
The Night Lord remained resolutely unphased.
'What else? Nothing, to be sure — if, as you say, the killer was sent to avenge the terrors of the Horus Heresy.' He leaned forwards again, as far as his chains would allow, and his black eyes were pools of oil, sucking her soul down into their lightless depths. 'But, child, the assassin that killed the Night Haunter was not the first to seek him out.'
'W-what?'
'She was the last of a long line. A line that he had evaded at every stroke. A line whose endless attempts had exhausted him beyond his desire to retaliate. He had endured enough, do you understand? He was the hunter! He was the first, and the mightiest! He ruled the shadows! He reigned in the Dark! And then his father rescinded his sanction, and at the end of the Great Crusade, before the Heresy had even begun, he was brought before his lord and his brothers, humiliated, and held to account. Did he betray the Emperor's honour, then? Did he excuse his actions by telling the truth? By revealing to his kin their father's duplicity? No. Loyalty gripped him still, and he endured his father's derision with boundless humility.'
'I remember the tales...' Ancient texts swam through Mita's memories, the echoing spaces of dusty libraries vivid in her mind. 'He attacked his brother-primarch, Rogal Dorn. Where was his loyalty then, Night Lord?'
'Dorn's pomposity infuriated him. Was it not enough that he had toed his father's line, without the chiding of ignorant fools? Of course his temper snapped. Whose would not have?'
Mita opened her mouth, a suitably acidic reply prepared, but stalled herself. There was little acid left in her, and that which remained was certainly not directed at the melancholy creature suspended above.
'What happened?' she breathed.
'My master was confined to his quarters. He sought time to meditate, to confer amongst his honour guard.'
'And?'
'And the conference was interrupted by a black-suited devil. An assassin, child. You understand me? Sent to kill the Night Haunter. Sent to silence his outbursts. Who else could have sent him? Who else but your holy, righteous Emperor? And, witch, remember: this was long before Horus unveiled his treachery and turned from the light!
'That's... that's impossible...'
'The attack was foiled and my master flew into a rage. Finally he recognised the truth of his father's so-called "justice". He fled from the conference to gather his strength, to consider his movements, to fume at the insult of the attempted murder.
'It was the first of many. Before, during and after the Heresy. On Tsagualsa the Night Haunter stopped running. He built a palace that he knew would be his mausoleum, and he awaited the bitch that would take his head and steal his crown.
'So you see, child, the Haunter was not killed for his part in the Heresy. He was not killed to halt excesses or unsanctioned behaviour. No... no, he was kitted by a father who thought nothing of using him. Of twisting him into a hated monstrosity. Of demanding atrocities and horrors from him to scare his enemies into submission. Of taking from him everything that was pure, everything that was human, and then repaying the sacrifice with betrayal.
'So tell me this, little witch. Do you still believe you aren't being used? Do you still think you'll find some... some reward in death for your loyal service? Do you still think the hatred of the masses is irrelevant?
'Do you still think your Emperor loves you, girl?'
If she'd had a stomach, if this incorporeal realm had taken form and replaced her astral self with a physical body, she knew she would be vomiting blood at the disgust that gripped her. Disbelief battled certainty, the doubts spiraled and flocked to dominate her whole soul, and like an island sinking beneath the sea, like a ship that had been considered impregnable splintering apart and slipping down into cold and lightless depths, every shred of faith that Mita Ashyn had ever felt in the Emperor of mankind crumbled to dust.
She peered through her tears, raised the gun, and fired.
The chains that bound the Night Lord to his crucifix splintered and unravelled.
Zso Sahaal smiled a savage smile, and tore free of the prison inside his own mind, to reclaim what was his.
PART FIVE
DOMINUS NOX
We are coming for you!
Zso Sahaal
It was not a gentle awakening.
He arose from the mire of sleep — that psychic trap that the warlock had constructed around him — with red rage in his eyes and every muscle tightening together. He felt the cords stand out on his neck. He felt the knuckles of his hands strain against the flat blades of his claws, brandished before him like a bevy of swords. He felt the talons of his feet — autoreactive pinions studding the periphery of each boot — scratching at the metallic floor on which he'd awoken, pushing him upwards.
All without conscious thought. All at the whim of his fury alone.
He felt the rush of boiling air as his jump pack swooned to life, and the dizzying acceleration as he left the ground.
He felt the soup of hormonal insanity that was his armour's chem-boost deploying into his flesh like a liquid sigh, and for the first time he did not struggle against it. For the first time he welcomed its unsubtle burst, he drew its burning promises into his blood as if accepting a second layer of armour, and he opened his mouth and screamed like a flaming banshee.
There was alien blood patterning his claws before his mind had fully thrown off the shackles of slumber.
They had not expected his revival, that much was clear. He was upon them like a lion before even they, blessed with lightning reactions and impossible grace, could react. The first he clove in two with contemptuous ease, turning away and rolling as he touched down from a shallow swoop, tumbling onto his injured shoulder and springing upright. A second startled xenogen appeared before him, fumbling for its weapon, and he tore through its frail chestplate as he rose. The tips of his claws slipped so far through eldar meat that they cracked the inner orbs of the alien's eye-slits, like branches growing from within. He shook the body away and leapt onwards, luminous fluids drizzling clear.
