Macragge - The Ultramar Campaign and the Terran Crusade: Soon after the Iron Warriors' Invasion of Ultramar was defeated in 999.M41, Abaddon the Despoiler's 13th Black Crusade began in earnest. In the days immediately after the fall of Cadia the Despoiler was informed by the Chaos Sorcerer Zaraphiston of a disturbing reality. The Sorcerer had discovered through his Warp-scryings that the Archmagos Dominus Belisarius Cawl had escaped Cadia's destruction with a device in his possession that could turn the tide of the Long War in favour of the Imperium of Man. The Despoiler also learned that Cawl was one of a number of survivors of Cadia, now calling themselves the Celestinian Crusade, who had escaped into the Webway with the aid of the Eldar Ynnari and were making their way to Macragge, the homeworld of the Ultramarines Chapter. To neutralise the nascent threat to his coming triumph over the Corpse-Emperor, the Despoiler detached a portion of his Black Fleet and ordered a Chaos invasion of the Realm of Ultramar as part of the 13th Black Crusade.The Celestinian Crusade, named for Saint Celestine, the Living Saint who had come to aid the defenders of Cadia in their darkest hour, was led not only by its namesake but also by Archmagos Cawl, Marshal Marius Amalrich of the Black Templars, and Inquisitor Katarinya Greyfax of the Ordo Hereticus. These individuals, joined by the Ynnari's commanders Yvraine, the Daughter of Shades, and her war leader The Visarch, first stepped from the Webway and onto the soil of the Shrine World of Laphis in the Macragge System. They were surprised to discover that they had set foot in a war zone, but they soon defeated the local Chaos forces that had been in the vicinity of the Webway portal. The Celestinians and their uneasy Eldar allies defeated the Heldrakes besieging the local Ultramarines fortress and then convinced the Space Marines to grant them passage to Macragge, though Yvraine and the Visarch sent the majority of the Ynnari back into the Webway to carry out missions more pressing for their people.The Celestinians arrived at Macragge aboard an Ultramarines Strike Cruiser to discover that the capital world of Ultramar had come under a full-scale invasion by the Forces of Chaos. While a massive battle raged in orbit between the Chaos and Loyalist fleets, on the ground the Fortress of Hera, the Ultramarines' fortress-monastery, was in danger of falling to the Archenemy. Gaining an audience with Marneus Calgar, the Chapter Master of the Ultramarines and the Lord of Macragge, Belisarius Cawl revealed that he was over 10,000 standard years old and had known the Ultramarines' Primarch Roboute Guilliman during the time of the Horus Heresy. Cawl explained that he had been tasked by Guilliman with finding a way to restore the Primarch to life even before his mortal wounding by the Daemon Primarch Fulgrim in the time after the Heresy.After much debate, the Celestinians and the Ynnari were allowed into the Temple of Correction where Guilliman sat in stasis despite Chapter Master Marneus Calgar's reservations about the newcomers.While Cawl began his work on the time-frozen body of Guilliman, seated upon his throne in the temple, the Black Legion took notice of the activity and launched a massive assault upon the Temple of Corrections, fearful of what the Loyalists were attempting. The Celestinians, aided by the Ultramarines' officers and the 3rd Brotherhood of the Grey Knights led by Grand Master Aldrik Voldus who had come to Macragge to aid the defence, faced off against over a hundred Black Legionaries. Yet, even as the Loyalists fought to give Cawl just one more solar second to complete his work, more Chaos forces poured into the shrine from above using Dreadclaw assault boats, and the defenders quickly found themselves overwhelmed.Only then, at the last, did Yvraine call upon the power of her patron, Ynnead, the recently awakened Eldar God of the Dead. The alien god's power over life and death combined with Cawl's arcane technology to heal the Primarch's wound and awaken him from his ten-thousand-year slumber. An awakened and enraged Primarch proved more than the Chaos attackers were prepared to deal with. Guilliman shattered the attacking Forces of Chaos and provided an extraordinary surge in morale for his Ultramarines and the other Loyalist forces. The Imperials quickly swept the Black Legion before them, breaking the back of the Chaos assault upon the Ultramarines fortress-monastery. In that one moment of resurrection, the fate of Macragge and of all Ultramar was decided.In the wake of the battle in the Temple of Correction, Guilliman was crowned as the restored Primarch of the Ultramarines Chapter and all of its Successor Chapters, and as the Lord Macragge and ruler of Ultramar. Marneus Calgar happily ceded the role of Chapter leadership to his gene-father, while Guilliman declared that the autonomy of all the worlds that had once belonged to the Realm of Ultramar and gone their separate ways in the millennia since the Horus Heresy was revoked. Ultramar was to be restored to what it had been in the golden age of the Imperium, a miniature stellar empire comprising five hundred human-settled worlds. Once in full control of the Loyalist forces on Macragge, the Primarch's strategic genius was unleashed, and the Forces of Chaos were driven off of Macragge and then from most of Ultramar within approximately seven solar months.With Ultramar safe for the moment, Guilliman decided that the time had come to journey to Terra and meet with his father the Emperor for the first time in ten millennia, beginning what became known as the Terran Crusade.Gathering forces from all across the Imperium who were able to reach Macragge as the Warp grew ever more turbulent in the wake of the 13th Black Crusade, the Primarch assembled a massive Crusade Fleet to reach Terra. Leaving Macragge and Ultramar in the capable hands of Marneus Calgar, Guilliman's fleet was passing near the great Warp rift known as the Maelstrom when it was intercepted by a Chaos fleet led by the Daemon Primarch Magnus the Red and his Thousand Sons Traitor Legion. Magnus had stirred himself from the Planet of the Sorcerers for the first time in millennia in recent days, to assault the Fenris System of his ancient foes the Space Wolves, and now to confront his former brother. The Thousand Sons Primarch cast a potent sorcerous ritual that flung the Terran Crusade Fleet into the Maelstrom, with no apparent way for it to escape from the labyrinthine clutches of that wound in reality.With time in the Warp indeterminate, the Terran Crusade wandered from Daemon World to Daemon World within the Warp rift, taking steady casualties from the constant daemonic assaults. All during this time Roboute Guilliman's guilt and frustration began to grow, weighing down his psyche as the Loyalists found it impossible to escape the Maelstrom's clutches. But a beacon of hope came when on one such world Guilliman received a psychic message from the Eldar Farseer Eldrad Ulthran, now an ally of the Ynnari, which laid out a series of landmarks for the Imperial fleet to follow to escape the Warp rift. But when the much-diminished Crusade reached the starship graveyard which marked the passage back to realspace, it was met by another massive Chaos fleet, this time of the piratical Chaos Space Marines known as the Red Corsairs, led by the Lord of Change Kairos Fateweaver. The Chaos forces assaulted every voidship in the Imperial fleet, and Kairos ultimately succeeded in defeating Guilliman by using his psychic powers to wrap the Primarch in chains literally crafted from his own guilt. Threatening the immobilised Primarch's life, the Greater Daemon forced the rest of the Imperial fleet to surrender.The Terran Crusade found itself in dire straits, brought by Fateweaver's command to a Blackstone Fortress hidden in the Maelstrom by the Red Corsairs, a secret gift from Abaddon the Despoiler. There the Primarch and his remaining followers would have rotted for eternity were it not for intervention from an unexpected source -- the Eldar Harlequins led by the Shadowseer Sylandri Veilwalker and Cypher, the mysterious Fallen Angel who was a sometimes enemy and sometimes ally of those loyal to the Emperor. In return for a promise to bring the Fallen Angel before the Golden Throne, Cypher freed the Primarch and his compatriots. With their starships lost to them, their crews sacrificed to the Ruinous Powers, Veilwalker offered another path to Terra -- through the Webway gate that lay at the heart of the massive xenos star fortress.The Terran Crusade passed successfully through the Webway towards Terra, only to discover that the Labyrinth Dimension was already haunted by Magnus the Red and the forces of the Thousand Sons. As Veilwalker explained that there had long existed a secret exit of the Webway on Luna, the moon of Terra, Guilliman realised that his daemon brother had been waiting for them. As soon as they opened the Webway exit in the Sol System, the Thousand Sons would rush through behind them, unleashing a major Chaos invasion right on Terra's doorstep, allowing Magnus to gain the glory ahead of the Despoiler. But with aid from the Harlequins and other Imperial forces such as the Sisters of Silence and the Imperial Fists, Guilliman and his Terran Crusade survivors managed to overwhelm the Thousand Sons and cast Magnus back through the Webway portal, permanently sealing it so that it could never be used again to threaten the Throneworld of the Imperium.At long last, Guilliman was escorted by the awed defenders of Terra to the Imperial Palace, where the survivors of the Celestinian and Terran Crusades at last went their separate ways. There, he finally met for one full solar day with his father, the Emperor of Mankind, for the first time in millennia. None know what was said between them, but when the Primarch emerged from the Inner Palace, he declared that he was taking up the mantle of the Lord Commander of the Imperium once more. Now the first among equals among the High Lords of Terra just as he had been after the Horus Heresy, Guilliman promised the people of the galaxy that he would assemble the greatest fleet and armies seen since the Great Crusade to take the fight to Chaos ... and revive the Emperor's lost dream of a better future for Humanity.
