There are some details around Lucius that I find often left out of discussion of the character, namely the daemonic entity afflicting of Lucius and other details surrounding it. This thread is my attempt to collect references around this subject.
It was born in lust and unthinkable atrocity. Coalesced from the anguish and joy of a billion souls across a billion lifetimes, it swam in the afterbirth of a new god, shuddering from the screaming reverberations that echoed without end from the wound its arrival had torn in the fabric of the universe. From deep within this realm that joined real and unreal, it slipped out from the Sea of Souls, and onto the land of souls. It caressed the material void with questing tendrils. It was a whisper, a mellifluous zephyr that had tempted the ambition of kings and twisted entire worlds into writhing monuments of flesh, shrines for the master of pain and pleasure who was the Youngest God. It was honey and silver and the laughter and cries of aeons of sentient life. It was all of these things, and more. It watched the day and night pass over the empires of man, rising and falling, swelling and starving. It watched as they laid claim to the stars, and first drank from the cup offered by the realm of the gods. It watched as those who drank turned upon those who would not, and set their galaxy afire. Champions rose, and as a shining son was born anew within the cradle of the Dark Prince, it found the object of its desire. It watched as his hearts were pierced by midnight blades, and fate flew to pull him into the dark. A million denizens of oblivion waited across the veil, howling and slavering for the feast of his soulfire as the last of his life ebbed away. It moved closer, and in an instant it was there, looming over his stricken form, watching the lifeblood drain from his veins to grow cold and still. So long had it waited for this moment. The one born of lust and atrocity reached down, and smiled.
The blade did not move. It stayed resting against the World Eater’s throat, and no cut was made. No sacred gasp as airways and arteries were opened into the air, no transcendent splitting notes of flesh peeling apart as head separated from neck. Lucius’ smile soured into a sneer. His brow furrowed, lip curling in anger as he fought to control his own sword arm. Still it defied him, refusing to move. Worms of trembling numbness bloomed in his fingertips, spiralling up his arm as the limb rebelled against him. The swordsman snarled, releasing his lash to hang loose as he clamped his other hand over his wrist. The muscles of his sword arm locked tight, sinews pulling taut and constricting the bones in crushing seizure. A stink like roasting hair rolled up Lucius’ palate and flooded his nostrils. His vision narrowed, the way ahead stretching into a long corridor slowly filling with oily water. Sound ceased, replaced by a shrill ring that fluttered his eardrums, and the swelling screams of the captive killers within his mind. Vertigo stole the balance from his legs. A cold hammer blow sprang Lucius’ world back into focus. A gasp burst from between his teeth as the Red Centurion’s gladius punched into his side.
Lucius staggered back, his arm still locked stiffly out in front of him. The exterior of the Pit Cur began to rattle and shake beneath his boots. The twisted faces pressing up from the surface of his armour shrieked in a horrid chorus of disunity, filling his ears to join his mind with their overlapping syncopated screams.
Something had intervened to thwart the glorious triumph that was Lucius’ by right. He had experienced similar sensations before, moments where he lost control. In the past they had been minute tugs at his limbs or an icy numbness creeping over his flesh, but it had never been this severe, never enough to arrest him so completely.
‘We picked this region specifically for the fact that, for the meantime, there is nothing here, but that could change at any–’ ‘Something to say, brother…’ Clarion turned, her gold eyes flicking back in a sidelong glance. ‘What?’ Lucius was leaning over the table, knuckles flat against the polished metal, eyes staring glazed and unfocused into the dancing screeds of hard light. His mouth slowly moved as the words came out in a soft murmur, barely even a whisper. None of the bridge crew, caught up in their duties, heard it. But Clarion did. Clarion leaned forwards in her throne, looking closer. The hulking robed figure standing on the other side of her, half hidden in shadow, remained silent and unmoving, avoided by all. The child watched the warlord as his words drifted away and his eyes refocused. Lucius straightened, as if waking from a dream, lifting a hand to brush a trickle of dark blood from his nose. He looked down at Clarion, into shining eyes that stared into him with the undisguised fascination of a magos studying a pinned laboratory specimen.
Lucius’ false smile soured to a grim line. A tic twitched at his left nostril as his eyes narrowed. His voice was low, a growl barely above a whisper. ‘I. Am not. Cursed.’ Kyoras’ bolt pistol did not waver. ‘Reality exists unconcerned of whether you believe it or not, Eternal One. Look around you. Our ability to make war on any level above base piracy has vanished. Our brothers stumble aimlessly across this ship, their stares distant, their nerves unable to send the sensation they crave riding through their bodies. They can only be brought to feel through the machinations of your Apothecary’s potions, and even then it can do little more than remind them of what they have lost. To continue upon this path is–’ ‘Insane.’
‘Now leave me be, Apothecary. Your incessant melancholy throws my humours out of balance.’ Cesare watched Lucius disappear into the stark bands of coloured light and rippling waves of sound. He glanced down, reading the results of his narthecium’s passive scans as they spilled over the datascreen of the gauntlet in screeds of sharp green runes. He released another sigh, his eyes turning back to the now empty corridor. ‘Out of balance, indeed.
‘Yours is a curious case, brother,’ said Fabius, watching as Lucius struggled inwardly. ‘Consistently exposing yourself to the extradimensional intelligences that you and our deluded brethren worship has provoked a uniquely malignant form of schizophrenia to take root within your mind.’
Lucius staggered to one knee. He fought to stand, to move, but his body refused to obey his commands. He felt it, more than he ever had before, uncoiling from inside the deepest part of him. It was ice, and shadow. It had been so patient. It had waited for so long, just beneath the surface, growing stronger. Bolder. Lucius felt it drink his synapses, leeching the bylestim from his blood, using the warpborne essence of it to take control. Taking, taking. It wrested hold of his muscles, drawing them into cramping, locked knots around his bones. Paralysis gripped Lucius, cementing him in place. His world darkened beneath a monstrous shadow as the Bloodthirster’s pounding tread brought it over him. Blood-pinked foam flecked from the Eternal’s lips as he heard the voice laughing behind his eyes. Yes, it cooed. Die, Lucius. Die and come to us.
The Bloodthirster turned its blistering gaze back down upon him. Agony ripped at the Eternal’s soul as he felt the screams building and building in power. Lucius readied himself, feeling the wrath of his killers become a physical force breaking open his skull. He bore the pain, preparing for the moment, exceedingly rare due to the threat it courted, where he would use their unceasing siege to his advantage. ‘You will not use me,’ Lucius snarled. ‘It is I who use you!’ Lucius relented, relaxing the crushing hold his will held over his bound killers for a fraction of a second. Every wailing maw that strained against his cracking armour shrieked, releasing their pent up malevolence in a deafening crescendo.
Lucius shifted, almost stumbling as his knees locked. He fought to hold back the thing wrestling beneath his flesh. He could not hear the cheers of the Faultless before him, only the screams of imprisoned killers formed into a blade wielded by a single voice. ‘Agony!’ ‘Ecstasy!’ …more.
‘Why do you remain?’ he asked, looking to the massive seat at the centre of the command dais beside him. ‘Why come back for me?’ Clarion stood upon the ornate seat of her command throne, her child’s body still not even reaching his gorget. ‘Because of you,’ she replied, with the smile that always reached her golden eyes. ‘You, Lucius. You fall, you rise, you continue on, refusing to believe your failures until once more they strike you down. You return, slowly diminishing, but unwilling to stop, unwilling to succumb. You are your race, Lucius. You are humanity, and as with the rest of your kind, I delight in your dance, all the way to its end.’
The Composer nodded. He stroked a flask hanging from his belt, where thebound essence of what had once been a tortured slave was held. ‘But what happens when you reach perfection? The achievement of what is so widely considered impossible. What happens when you get there, and discover that perfection is not the end? When you learn that perfection is only the turning of a key, a signal sent to a higher place that you are worthy of being told the truth of the universe? ‘Enlightenment is not found outside of you. Real truth is inside of you, and always has been. To find it, you must cut away everything, lower and deeper until you reach the bottom. Once there is nothing left, all that remains is the truth. That is what is happening to you, Eternal. You are on the cusp of discovering the real truth.’
