Terran Crusade - Gods of War: Drawing himself up to his full height, Magnus the Red raised his ensorcelled glaive and spoke dolorous words of power that rang out in defiance of all natural law. Purple flames leapt, forming shimmering shields and warding the Thousand Sons from harm. Suddenly, the Rubricae and Scarab Occult could advance unharmed, striding upwards as their foes' shots exploded upon Magnus' psychic shields. The Thousand Sons suffered no such obstruction, and dozens of Loyalists were sent tumbling back from the crater's lip, blood and shattered bone spraying.Seeing the sudden shift in the situation, and knowing that they must hold out no matter the cost, Guilliman ordered his surviving warriors back. Moments later, the first ranks of Rubricae crested the lip of the crater and strode out with their gun muzzles flaring. More Thousand Sons marched behind them, and the surviving Loyalists fell back to voidship wrecks and rocky craters to gain cover while their tanks backed steadily away with their guns thundering.Magnus rose from the crater. With a word, the Daemon Primarch unmade a trio of Dreadknights, burning out their psychic wards and crushing their armour. With a gesture, he telekinetically plucked an Ultramarines Land Raider from the ground and slammed it through ranks of Skitarii like a cannonball. Magnus brandished his staff and reality rent apart, a tide of cackling Tzeentchian daemons boiling from the Warp to join the battle.Recognising that the Daemon Primarch would swiftly destroy his army if allowed free reign, Guilliman broke into a headlong charge. Giving vent to a booming war cry, the Primarch of the Ultramarines smashed a path through the Rubricae before him and launched himself into a heroic leap from the lip of the crater.Guilliman soared, burning blade leaving a trail of flame behind him. Magnus saw his brother coming and began an incantation of pain, but before he could finish it the Lord of Ultramar struck. Magnus managed to parry his brother's arcing blade with his glaive, but the battering ram impact of Guilliman's leap carried the Crimson King backward, away from the fight. The two Primarchs tumbled across the lunar surface, dust billowing around them, and smashed into the rusted wreck of an Imperial frigate. Slabs of metal and corroded ironwork crashed down around them, burying the fighting brothers in an avalanche of wreckage. Meanwhile, the battle around the crater raged on, the last remnants of the Terran Crusade fighting furiously to survive.Guilliman fought his way to freedom, hurling aside a slab of rusted metal and ignoring the alarms ringing within his helm. His armour was compromised, its air supply venting and the cold of the void leaking in. Were it not for his god-like constitution, and Cawl's life-sustaining technology, Guilliman would likely have been dead.Instead, he raised his blade and kicked his way clear of the scattered wreckage."Magnus", he shouted through his Vox grill, searching around him. The Primarch knew his dubiously gifted brother could hear his words, even in the void of space. "I know better than to think you dead. Face me!"Deep laughter rolled around Guilliman, a sound redolent with ancient malice. As he watched, Magnus' ethereal form rose from the wreckage and drifted down to loom over him. The Daemon Primarch solidified once more, huge and menacing."Very well, Roboute", laughed Magnus, and his words conjured crystalline showers that rained down upon the pale ground. "Here I am, in the flesh. And -- somehow -- there you are." Magnus cocked his head to one side and smirked. "I don't remember you seeming so ... insignifcant.""Ten millennia have made you no less arrogant, then?" asked Guilliman, warily circling his towering foe. Inside his helm, a look of disgust twisted his patrician features as he regarded the monstrous form of the Crimson King. "Certainly those years have done you no other kindness."Magnus sighed. "How you can have such grand plans and yet such scant vision has always eluded me. This", the Daemon Primarch said, empyric energies stirring as they gathered around his levelled glaive, "is what true power looks like.""I see no power here", said Guilliman, shaking his head in dismay. "I see corruption, and enslavement to monsters that are worshipped as gods.""On that, Roboute," Magnus laughed, sparing a glance at the Loyalists fighting nearby, "perhaps we can finally agree."The cyclopean Sorcerer's smile turned into a sneer when he noticed his brother glance to the skies above. "Hoping to keep my sons and I occupied until the remnants of this palsied Imperium come to save you? I may not reach our father's throne room today, but I promise that you won't either. You will be dead long before help arrives. That alone will be worth all this trouble."With that, Magnus attacked. The giant moved far faster than even Guilliman could have believed, his ensorcelled glaive lashing out to split the Lord of Ultramar in two.Guilliman leapt backward, pulling his midriff in as he did so. Magnus' weapon drew sparks from his armour as it whistled past, and Guilliman landed atop the crumpled prow of a nearby frigate.Before he could take stock, Magnus was hurling balls of blue psychic flame at him. Guilliman threw himself out of their path, sliding down the prow's rusted flank and dropping into a crouch at its feet. He broke into a charge, bursting from the drifting cloud of dust raised by his landing and weaving skillfully around his brother's sorcerous projectiles.The ammunition in the Hand of Dominion was spent, but it was still a phenomenally powerful weapon. Sidestepping a downward cut from Magnus' glaive, Guilliman slid inside his brother's guard and delivered a thunderous uppercut. The impact lifted Magnus from his feet and sent him tumbling upward into the inky blackness. Fiery blood drifted in strings from Magnus' shattered jaw, causing kaleidoscopic fungi to sprout from where it spattered on Luna's surface, the power of change embedded even in the Daemon Primarch's blood.Roiling psychic energy wrapped around Magnus, arresting his motion and righting him as he howled in anger. The Daemon Primarch stared hatefully down with his single eye, and Guilliman knew fresh sorrow as he realised how truly mad and lost his sibling had become."Arrogance", shouted Guilliman. "It was always your undoing, brother. You thought this would be an easy fight, that the gifts of your so-called gods would render me impotent. Perhaps those you serve are not all you believed them to be?"Magnus' rage vanished in an eye-blink, and he laughed scornfully in response to Guilliman's jibe."You would like to believe that, wouldn't you? That the dutiful Roboute Guilliman was justified in his loyalty? That, now the ramifications of our choices have become clear, you can look down on me as you always did?"With sudden violence, Magnus jabbed downward with his glaive. Multicoloured flames exploded from its blade, engulfing Guilliman and the bedrock upon which he stood. Moon dust exploded upwards in crackling clouds. Fire danced across scrap iron, and Roboute cried out as agony wracked his body.Crackling with raw power, Magnus descended, still pouring Warp fire into his brother. Guilliman screamed again, dropping to one knee as his armour blazed with searing energy. Sparks burst from the overloaded systems of his Power Armour, and the smell of his own, cooking flesh filled his nostrils.Desperate, Guilliman drove himself backwards in a graceless leap. He flew in an arc to smash down amidst a tumbled heap of enginarium debris, armour still flickering with flames.Magnus landed, chuckling cruelly. Sprawled amidst the tangle of wreckage, Guilliman tried to push himself to his feet. The Primarch's body was a mass of pain, and his armour responded sluggishly, a number of its servomotors burned out."No, brother", said Magnus. "You stay where you are."The Daemon Primarch gestured, and spectral claws tore several hundred tons of machinery loose from a nearby wreck. Guilliman had time to brace himself before the ungainly mass impacted like a comet, burying him completely beneath an avalanche of crushing metal.Guilliman was entombed. Alarms chimed in his ears, red warning signs flashing in his peripheral vision. The pain of lacerated organs and shattered bones dragged at him, and for a moment the Lord of Ultramar was tempted simply to give in. Then he thought again of his long-suffering sons, fighting so hard for the ideals of an Imperium they had never even known. He would not betray them. He would not let one of his degenerate brothers keep him from his responsibilities -- not again.Muscles tensing, strength surging, Guilliman ripped his way up through the tumbled mountain of wreckage. He roared as he hurled aside a capacitor unit the size of a Land Raider, and stepped, bloodied but unbroken, into the hard light of Luna. Magnus arched an eyebrow at the sight, and braced his glaive to hurl another spell.And then the void lit with fire.
