Terran Crusade - War Zone Ultramar: As the armies of reconquest gathered upon Macragge, so ever more Imperial forces came seeking the Primarch. Some, like the Dark Angels and the Raven Guard, sent small delegations to determine the veracity of this miracle. Others came in hope and celebration, bands of Space Wolves, White Scars, Black Templars and others hastening to the Primarch's side. A glorious moment came to pass when the Black Templars made planetfall, for they were reunited with Marshal Marius Amalrich, who alone of his brotherhood had survived the battle in Guilliman's shrine. Taking one look at the zealous light in Amalrich's eyes, the Black Templars Chaplains declared him touched by the hand of the Emperor. The Marshal was brought aboard the Strike Cruiser Scourge of Heretics, and girded with the armour and the Black Sword of the Emperor's Champion.Others, too, came to Ultramar upon the insistence of their seers, Astropaths, soothsayers and lords. Battleships of the Imperial Navy, regal Barons of Imperial-aligned Knight Worlds, fleets of warships from the Adeptus Mechanicus and their Titan Legions, processions from the Adeptus Administratum; all came to offer fealty to the Primarch.A grotesque cyber-synod of the Adeptus Ministorum descended upon the Fortress of Hera and insisted upon first confirming, and then proclaiming, Guilliman's alleged divinity. The horrified Primarch agreed to such beatification only after Celestine and Greyfax impressed upon him just how powerful the Ecclesiarchy was in the Imperium of the 41st Millennium. Better to have them as a firebrand ally than an obstreperous foe.Before his departure from the fortress, Guilliman had one more order of business. He decreed that now was an age of wrath and war, in which learning and lore must be set aside. The Primarch shocked his Chapter by ordering the great Library of Ptolemy barred to all comers on pain of death. Every last tome, every lingering, dangerous secret contained within that ancient repository was locked behind adamantium bulkheads and Servitor guns. At the same time a new war room was built. This was the Strategium Ultra, from where Guilliman's reconquest could be plotted, tracked and coordinated.When finally the armies of reconquest were ready to set out, Roboute Guilliman led them into battle with something akin to relief. After the endless political infighting and bureaucracy of this turgid new Imperium, the thought of a battlefield seemed almost welcoming.Guilliman began with the Macragge System itself, several of whose worlds were beset by the Forces of Chaos. A warband of Iron Warriors known as the Bitter Sons had invaded the Hive World of Ardium, conquering one of the planet's three subterranean hive cities and fortifying its winding tunnel networks. Linking up with the surviving Auxilia garrisons of Hives Geodrane and Tarnis, Guilliman led elements of the Ultramarines 4th and 6th Companies through a subterranean hellscape to assault Hive Magmaria. The fighting was savage in the extreme, the outnumbered Iron Warriors clinging tenaciously to their defences until the last man. Corpses choked entire magtunnels, and blood filled the undersump until it overflowed through the hive's drainage grilles. In the end, Guilliman and his gore-drenched followers emerged victorious.The Shrine World of Laphis became the site of the liberation's greatest naval engagement when the Ultramar Defence Fleet engaged the ships of the Alpha Legion blockading the planet. Marneus Calgar commanded the offensive, seated in the captain's throne aboard the ancient flagship Macragge's Honour. The Ultramarines vessels swept in through the void with their guns thundering, successfully driving back those Alpha Legion voidcraft engaged in surface bombardment. Triumph turned to horror when a flotilla of fleeing Imperial bulk carriers were revealed to be crewed by Alpha Legion Chaos Cultists. Packed with explosives, the lumbering haulers ploughed into the Ultramarines starships and crippled several. Calgar had expected treachery from his foes, however, and now revealed his own masterstroke as a second, reserve fleet of swift Strike Cruisers and frigates swept in from behind Laphis' third moon, Aurora. At the same time, elite strike units containing Ultramarines Techmarines dropped onto Laphis' surface and succeeded in awakening the world's battered orbital defence grid. Caught from three sides, the Alpha Legion warships were torn apart, left as a belt of drifting wreckage above the Shrine World.Through such heroic actions was the Macragge System made secure, allowing the armies of Imperial reconquest to sweep on towards the neighbouring star systems that made up the Realm of Ultramar. That stellar domain had once comprised five hundred human-settled worlds, before Lord Guilliman had granted many their own sovereignty after the Horus Heresy. All such treatises the Primarch now declared null and void, the Five Hundred Worlds of Ultramar reborn like their ruler. In such grim and desperate times, he would see his personal empire forged anew, for in this, as in all things, Guilliman desired strength through unity.Onward through shuddering Warp Storms and Traitor hosts swept the armies of Ultramar. Not once did they falter. Iron Hands fought alongside Praetors of Orpheus on Talasa Secundus. Dark Angels went to war beside Titans of the Legio Fulminari to liberate Ischara. The chanting processions of the Cult Mechanicus fought shoulder to shoulder with Novamarines and Battle-Sisters of the Order of the Ebon Chalice against mutant hordes on the killing fields of Konor Prime. Unified and elevated by the leadership of Roboute Guilliman, their war efforts coordinated with clockwork precision from the Strategium Ultra on Macragge, the armies of reconquest overcame Warp Storms, Traitor armies, and even daemonic incursions in their battle to drive the ravagers of Chaos from ever more worlds. Yet still the fight ground on, solar weeks becoming solar months, for Ultramar is a vast stellar realm and its numerous invaders, the fires of their old hatred stoked, were obstinate. The Long War raged, worlds burned, and blood stained the stars.
