Saint Celestine - The Terran Crusade: The Reborn Aeldari guided the Celestinians through the Webway to the Realm of Ultramar in the Eastern Fringes of the galaxy, now also under ferocious assault by the forces of the Despoiler. After some initial distrust, the Celestinians were ultimately taken by the Ultramarines who called Ultramar home to the realm's capital world of Macragge.Once in the Ultramarines' Fortress of Hera, Cawl revealed the identity of the artefacts in his accompanying auto-reliquary. He declared that they were intended to resurrect Primarch Roboute Guilliman from the mortal wound that had seen him trapped in stasis in the Temple of Correction for the last ten millennia.While the Celestinians and the Ultramarines were under potent assault by the forces of Chaos within the primarch's final resting place, Cawl worked with Yvraine, the Daughter of Shades and priestess of Ynnead, the Aeldari god of the dead, to restore the primarch's life force while Cawl's technology healed his grievous wound.The resurrection of the primarch was held to be a miracle brought about by the will of the Emperor. Celestine's unrelenting faith in the Master of Mankind had been spectacularly rewarded, and this resulted in the end of the rift that had existed between her and the Puritan Inquisitor Katarinya Greyfax, who had believed the Living Saint to be a fraud and dupe of Chaos.But the return of a living primarch, one of the Emperor's own sons, revealed the depth of Greyfax's own errors of faith. She, too, now came to believe that Celestine was a true servant of the Emperor and instrument of His will.With Guilliman resurrected, he drove the invaders from Ultramar before deciding to make his way to Terra through the Warp anomalies roiling the galaxy to an extent not seen since the Horus Heresy.Celestine joined the primarch on this Terran Crusade, her combat prowess and unwavering faith aiding the Imperial forces of the Crusade in all their trials and tribulations in the Warp rift known as the Maelstrom.More than once when trapped in the Maelstrom, the Imperial ships were forced to fight off opportunist raids by sleek hunting packs of Traitor warships. Amidst a thousand-mile-wide cloud of corrosive spores, the Terran Crusade ships found themselves beset by swarms of vast plague flies as large as frigates.The monstrous insects took a savage toll upon the smaller ships of the crusade, until Celestine took to the Navigator's observation blister of the Ultramarines flagship Macragge's Honour. Unleashing her holy light in a blazing psychic shockwave, the Living Saint purged the hideous daemon beasts from the void.The survivors of the Terran Crusade finally arrived in the Sol System at Luna through the Webway after being freed from imprisonment in another Blackstone Fortress belonging to the Red Corsairs. Following the crusade's rescue by the Fallen Angel Cypher and a troupe of Harlequins, Celestine was one of the few Imperials present at the fall of Cadia to survive both the Celestinian and Terran Crusades.After aiding in the defeat of the forces of the Thousand Sons Traitor Legion and the Daemon Primarch Magnus the Red on Luna, Celestine and her allies were finally ferried to the Imperial Palace on Terra. There, before the Ultimate Gate of the Sanctum Imperialis leading to the throne room of the Emperor where Guilliman would meet his father for the first time in ten standard millennia, Celestine moved to minister to the frayed hordes of desperate pilgrims and penitents.Always determined to spread the light of the Emperor wherever she went, Celestine became a beacon of hope to all of Terra's oppressed and downtrodden. Guilliman emerged a solar day later from the palace and was soon restored to his former position as Lord Commander of the Imperium. As he prepared to launch a massive counteroffensive against the gathering forces of the Ruinous Powers, there was no doubt that Celestine would stand at his side once more.
