Ultramar Campaign - Revelation and Rebirth: Entering the resting place of Roboute Guilliman was like stepping into some doleful warrior's afterlife. The chamber itself was enormous, a vaulted sepulchre through which a Warlord-class Battle Titan could have strode without hindrance. Marble columns held aloft a ceiling of stained armaglass and obsidian inlaid with theldrite moonsilver. Guilliman's greatest deeds were depicted in spectacular friezes and statuary, arranged around the chamber and lit artfully by flickering electrosconces to lend the images the greatest possible gravitas. Huge braziers of devotional incense burned throughout the shrine, lacing the air with subtle scents, while from cherub-visaged laud hailers spilled a steady background murmur of martial arias and reverent prayer.Despite the grandeur of the shrine, the pilgrims' eyes were drawn to the splendid figure enthroned within a pool of stark white illumination at one end of the chamber. There, upon a throne of marble, gold and finely worked adamantium, sat Roboute Guilliman. Esoteric machineries loomed over the Primarch's throne, thrumming and whispering as they fed remarkable energies through ribbed cables to enfold him in a rippling stasis field. Guilliman sat as though in repose, his eyes closed and his blood glinting jewel-like in a delicate necklace about his throat. Guilliman wore his finely-crafted Power Armour, still marred by the damage it had sustained during his final duel with the Daemon Primarch Fulgrim. Across his knees was laid a grand blade of prodigious size, the "Emperor's Sword", once wielded by the hand of the Master of Mankind Himself. Though the Primarch sat peacefully upon his throne, the force of his presence was palpable.The pilgrims approached the throne in reverent silence, their Ultramarines escort marching alongside them and Cawl's auto-reliquary at their rear. The group drew to a halt near the foot of the steps that led up to the Primarch, where countless Ultramarines had knelt in communion over the millennia. Marneus Calgar moved forward to stand at the very base of the steps, bowing his head reverently to his Primarch for a moment before turning to face the assembled pilgrims. The sounds of furious battle were still audible, even in this sacred place, muffled and distant but inescapable.Calgar drew a deep breath, and then asked once more for Belisarius Cawl to state his business here. The Chapter Master had indulged his visitors thus far, but with a desperate battle raging outside his fortress' walls, he could offer them no more time or patience.Magos Cawl inclined his head, and told an incredible tale. Cawl explained that, in the years before Guilliman was mortally wounded, the Primarch had summoned him into his confidence. Cawl's memengrams of that meeting were eroded and incomplete, but he believed that Guilliman had seen in him the potential for great things. The Magos had been charged with a great labour by Roboute Guilliman, one for which he would be richly rewarded with information that only a Primarch could provide. Cawl stated that he was not at liberty to reveal the nature of his task, forestalling Calgar's angry response by explaining that his labours had been divided into two distinct parts, and that he was here to deliver on the first of those. He brought a magnificent new suit of armour fit for the Ultramarines Primarch, one whose ancillary systems possessed the power to heal Guilliman's grievous wounds. Stunned silence reigned at this announcement. To bring back a living, breathing Primarch, to restore one of the Emperor's greatest sons to the Imperium in its hour of need; such a notion filled the Imperial warriors with awed wonderment.Yvraine spoke up, explaining her presence at this seminal moment. She was the Emissary of Ynnead, the Eldar God of the Dead, and her powers would be vital to Guilliman's restoration. Reading the puzzlement on her audience's features, Yvraine explained with sharp impatience that such a miracle could not be brought about without sacrifice. Cawl had laboured long and hard to fulfill the Primarch's request, but without Ynnead's aid, the fruits of that labour would not be enough. In order for Roboute Guilliman to live once more, first he must die.Where Cawl's words had been met by shocked silence, Yvraine's raised a storm. Calgar exclaimed his fury at such a notion, vowing that no xenos witch would ever lay hand upon the Primarch while he drew breath. Grand Master Aldrik Voldus moved to stand alongside Calgar, his expression grim, and Greyfax and Marshal Amalrich followed his example. The surrounding Ultramarines raised their weapons, pointing them at Cawl, the Ynnari, even the hulking shape of the auto-reliquary itself. They awaited only their master's order to open fire.Yet others raised their voices in support of this apparent insanity. Cawl blurted loudly that he was bound by the terms of his pact with Guilliman, and that he must bring it to completion. Saint Celestine too spoke up, imploring those around her to have faith, and asserting that this was, indeed, the will of the Emperor. Most unexpected of the proponents was Chief Librarian Tigurius, who strode, Force Staff ringing against the stone floor, to stand alongside Magos Cawl. Tigurius spoke in a calm voice that cut through the clamour, asking Lord Calgar to trust his counsel and saying once more that he had seen hints of this future in his visions. It was a scene of anger and confusion, but it was about to get worse.
