Battle of Prospero - Duel of the Crimson King and the Wolf King: The Crimson King and the Wolf King met in battle, with the fate of an entire world balanced on the outcome, and they fought like the gods of ancient Terran legends. Forking traceries of lightning shot upwards from the ground, isolating them from the host of the Space Wolves and the Custodes. Russ rained down blow after blow on Magnus, shattering his horned breastplate, and in return Magnus struck his brother with a searing blast of cold fire that cracked his armour and set light to his braided hair. The Wolf King’s Frostblade struck at Magnus, but his golden Power Axe turned the blow aside as they spun and twisted in an epic battle beneath the madness of a blazing storm of sheet lightning and pounding thunder. This was a battle fought on every level: physical, mental and spiritual, with each Primarch bending every ounce of their almost limitless power to the other’s destruction.Magnus used his powerful psychic magicks, battering Russ with fists of telekinetic force wreathed in fire and lightning. Yet, Russ was a Primarch and such powers had little effect on him save to drive him to greater fits of rage. Magnus drove his fist into Russ’ chest, the icy breastplate cracking open and shards of Ceramite stabbed into the Wolf King's heart. In return, Russ snapped Magnus’ arm back, shattering it into a thousand pieces. A blade of pure thought unsheathed from Magnus’ other arm, and he drove it deep into Russ’ chest through his shattered armour.The psychic blade burst from Russ’ back and the Wolf King let loose with a deafening bellow of pain. A chorus from his Fenrisian Wolves added their howls to that of their master. The two enormous lupine monsters that accompanied Russ leapt upon Magnus, fastening their jaws upon his legs. Magnus slammed his fist into the black wolf's head, driving it to the ground with a strangled yelp, its skull surely shattered. With a bellow of anger, Magnus tore the white wolf from his leg with a thought and hurled it away over the heads of the army at Russ' back.Magnus and Russ were locked in battle high above the causeway to the pyramid, the furious horror of their struggle obscured by ethereal fire and bursts of lightning. A flare of black light erupted and Russ cried out in agony. His blade lashed out blindly and struck a fateful blow against Magnus’s most dreaded weapon: his eye. Magnus reeled back from the Wolf King, one hand clutched to his eye as his shattered arm crackled with regenerative energies. As broken and bloodied as Leman Russ was, he was brawler enough to seize his opportunity. He barreled into Magnus and gripped him around the waist like a wrestler, roaring as he lifted his brother’s body high above his head. All eyes turned to Russ as he brought Magnus down across his knee, and the sound of the Crimson King’s back breaking tore through the heart of every Astartes of the Thousand Sons.The Wolf King howled his triumph to the blackened heavens. Russ dropped Magnus to the mud and brought the Frostblade Mjalnar around to take the head of his defeated brother. With the last of his strength, Magnus turned his head, and his ravaged eye found his favoured son, Ahriman, "This is my last gift to you."Leman Russ’ blade swept down, but before its lethal edge struck, Magnus whispered eldritch words of power as his body underwent an instantaneous dissolution, its entire structure unmade with a word, and Ahriman gasped as vast and depthless power surged into his body. As it swept through him, he knew what he had to do. Ahriman clasped his hands upon the jade scarab set in his breastplate. He knew everything about that gem, and pictured the identical artefact on the chest of each Astartes of the Thousand Sons. Even as he visualised them, the power in him spread to the entire Legion as Magnus gave the last of his strength to save his sons, teleporting his beloved and infamous City of Light, Tizca, from the surface of Prospero and through the Warp and into the Eye of Terror, to rematerialise upon the Daemon World known as Sortiarius, the Planet of the Sorcerers. This new world preserved all of their precious knowledge hidden within its libraries that the Thousand Sons had gathered from all across the galaxy during the Great Crusade, and the Thousand Sons were saved from their enemies -- at the cost of their souls.
