Lorgar - The Raven and the Urizen Clash: Amidst the carnage and the slaughter, the anger of a demigod was released -- beyond anger, beyond rage. It went beyond both, for it was wrath, in physical form. Lord Corax, primarch of the Raven Guard, charged into the ranks of the traitorous Word Bearers, a blur of charcoal armour and black blades, butchering with an ease that belied his ferocity. Soon the voices of dying Word Bearers became a conflicting chorus over the Vox as they screamed for help. Argel Tal, the Crimson Lord and leader of the Daemon-possessed Astartes known as the Gal Vorbak, Lorgar's "Blessed Sons," leapt forward to meet their end at the hands of a demi-god.Meanwhile, Lorgar mirrored his brother primarch's actions, and slaughtered enemy Astartes with contemptuous ease. Just as the Word Bearers struggled to stand before Corax, so too did the Raven Guard fall back and die in droves. Suddenly, the Urizen halted his attack. He noticed that Corax was wading through the Gal Vorbak, ripping his Daemon-possessed crimson warriors apart. Given a blessed respite from the primarch's murderous advance, the Raven Guard were falling back from him in a black tide. They left their dead in a carpet at the primarch’s feet.Despite the protestations of both Kor Phaeron and Erebus, Lorgar disregarded their counsel and sprinted forwards across the churned earth and dead bodies of his brother's Legion to engage in a battle he had no hope of winning. He saw his brother – a man he had barely spoken to in two centuries of life, a man he barely knew – butchering his sons in a vicious rage. There was no thought of conversion. No hope of bringing Corax into the fold, or enlightening him enough to cease this murderous rampage. Lorgar’s own anger rose to the fore, burning away the passionless killing of only moments ago. As the Word Bearers primarch hammered his way through the Raven Guard to reach his brother, he felt power seethe within him, aching to rise out. Always, Lorgar had bitten back his psychic potential, hiding it and hating it in equal measure. It was unreliable, erratic, unstable and painful. It was never the gift it seemed to be for Magnus, and thus, he had swallowed it back, walling it up behind unyielding resolve. No more. A scream of release tore itself free, not from his mouth, but his mind. It echoed across the battlefield. It echoed into the void. Energy sparked from his armour, and a sixth sense unrestrained at last, with its purity perhaps coloured by Chaos, exhaled from his core. Lorgar felt the heat of his own fury made manifest. He felt his unchained power reaching out, not only to enhance his physical form, but reaching to his sons across the battlefield. And there he stood at the heart of the killing fields, winged and haloed by amorphous contrails of psychic fire, shouting his brother’s name into the storm. Corax answered with a shriek of his own – the call of the betrayer, the cry of the betrayed – and the raven met the heretic in a clash of Crozius and claw.In response, the Gal Vobak underwent their final metamorphosis, changing into their true Daemonic forms. Their ceramite armour had fused to flesh, layered by dense bone ridges and spines, as they sprouted all manner of razor sharp claws, talons and wings. They warped into new, bestial forms, marking them out as amongst the first Possessed Chaos Space Marines. Meanwhile, the primarchs fought in furious combat -- Corax fighting to kill, while Lorgar fought to stay alive. During their duel, Corax hurled insults and accusations at his former brother. He wanted to known why Lorgar and his Legion had committed such treachery? Lorgar shared with his brother of the future visions he had seen of their father -- a bloodless corpse, enthroned upon a throne of gold and screaming into the void forever. Angered by his brother's lies, Corax lashed out furiously with his pair of Lightning Claws across Lorgar's face, cutting the meat of his cheeks deeply. Even should Lorgar somehow manage to escape his ultimate fate this day, he would bear these scars until the day he died.The two primarchs traded vicious blows, but the Raven Lord had the advantage not only speed and finesse, but of also being a penultimate warrior with decades of fighting experience. Lorgar did not, for he had always been more of a scholar than a warrior, and his lack of experience cost him dearly as Corax impaled Lorgar through his stomach, the tips of his metre-long talons glinting to the side of his spine as they thrust out his back. Such a blow meant little to a primarch -- only when Corax heaved upwards did Lorgar stagger. The claws bit and cut, sawing through the Word Bearer’s body. Illuminarum slipped from the impaled primarch's fists. Those same hands wrapped around Corax’s throat even as the Raven Lord was carving his brother in half. Even as he tightened his grip on Corax's throat, the Raven Lord remained untroubled by his weaker brother's grip. Lorgar crashed his forehead against Corax’s face, shattering his brother’s nose, but still he couldn’t free himself. The Raven Lord gave no ground, even as a second, third and fourth head butt decimated his delicate features. The claws jerked, snagged against Lorgar’s enhanced bones. Corax tore them free, inflicting more damage than the first impaling had done. Blood hissed and popped as it evaporated on the force-fielded blades. Lorgar fell to his knees, hands clutched over the ruination of his stomach. As Corax stepped closer, he raised his one functioning claw to execute his brother. Lorgar screamed his defiance at Corax, lost in the irony that of all the sons of the Emperor, he was the one soul in twenty who'd never wished to be a soldier. And now here he would die, at the heart of a battlefield. As the claw fell, it struck opposing metal.Corax looked to meet eyes as black as his, in a face as pale as his own. His claw strained against a mirroring weapon, both sets of blades scraping as they ground against each other. One claw seeking to fall and kill, the other unyielding in its rising defence. Where the Raven Guard primarch's features were fierce with effort, the other face wore a grin. It was a smile both taut and mirthless -- a dead man's smile, once his lips surrendered to rigor mortis. It was Curze. Corax sought to wrench his claw free, but Curze's second gauntlet closed on his brother's wrist, so that Corax would be unable to fly away and escape his fate. Curze looked upon his prostrate brother and ordered him to rise from his knees, disgusted at his cowardice. Corax was not idle as this exchange took place. He fired his flight pack, burning his fuel reserves to escape Curze’s grip. The Raven Lord’s claw ripped free, and Corax soared skyward, carried on jet thrust away from Curze's rising laughter. Curze then shoved Lorgar back towards his Word Bearers.Around them both, the grey Legion warred with the warriors in black. Lorgar thanked his brother for saving his life. But Curze warned him that he would let him die next time. As bit out another retort, his words halted as he took in the scene of the transformed Gal Vorbak -- their armour was crimson and ridged bone. Great claws, both metallic weapons and fleshy, jointed talons, extended from bestial arms. Every helm was horned and every faceplate was split by a Daemon's skull-like leer. Disgusted by this horrific sight, Curze turned his back on Lorgar and commented that he was so much more than merely foul, he was rancid with corruption. Though grievously wounded, Lorgar would live. The traitors had carried the day and dealt the Emperor and the Imperium a grievous blow. As the Horus Heresy began in earnest, Horus now possessed nine Space Marine Legions and had all but destroyed three of the remaining nine Loyalist ones. The path to Terra was now wide open, and the decisive Siege of Terra and the assault on the Imperial Palace would follow after seven more Terran years of blood and terror as the Traitor Legions penetrated to the very heart of the Imperium of Man.
