Katarinya Greyfax - Terran Crusade: The Reborn Eldar 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 from their arrival point on the Shrine World of Laphis. On the journey from Laphis to Macragge, Belisarius Cawl purged Greyfax of the Necron Mindshackle Scarabs that had enforced her captivity during her time with Trazyn the Infinite. This process was effected over several solar days, and wracked the Inquisitor with terrible agonies as the invasive cyber-parasites were strained from her blood stream.Despite the pain that she endured, Greyfax's iron will never faltered, nor did she show any but the most minor outward signs of pain. Instead, she concentrated on keeping a wary eye on Saint Celestine. In private, Greyfax was beginning to suspect that Celestine's apparent divinity was more than a sham. She had seen the Living Saint battle against Arch-heretics and twisted Traitors; she had seen her predict events about which she could not have known in advance; she had seen how the light of Celestine's faith repelled the wicked and brought new strength to the righteous.Yet Greyfax was an Inquisitor of the Ordo Hereticus, a Witch Hunter whose first duty was to doubt and to suspect all that seemed fair in case it concealed foulness at its heart. In Greyfax's long experience, true miracles were few and far between, and that which seemed a gift from the Emperor was, more often than not, a tainted temptation laid by the Dark Gods. Thus, even as the seeds of hope grew in her heart that Celestine might be uncorrupted, and even through her own agonies, Katarinya Greyfax kept watch over the Living Saint, alert for the slightest hint of duplicity.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 Eldar 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 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.In her own way, in the midst of the battle in the Temple of Correction after the Primarch's sudden resurrection and dramatic turning of the tide against the Chaos attackers, Greyfax even apologised to the Living Saint."I erred," shouted Greyfax over the roar of her Bolter. "And I shall do penance. You truly are an instrument of the Emperor's will.""Vigilance is not a sin, Katarinya Greyfax," replied Celestine, slashing her blade through the enemies before her. "You serve Him as surely as I.""Indeed," said Greyfax with a curt nod. "Then let us serve him together, as true warriors of faith."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. Greyfax 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.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 Eternity Gate of the Inner Palace leading to the throne room of the Emperor where Guilliman would meet his father for the first time in ten standard millennia, Greyfax chose this time to depart and report to her Ordo Hereticus superiors for the first time in many standard centuries. Guilliman emerged a solar day later from the Palace and was soon restored to his former position as Lord Commander of the Imperium. As Guilliman prepared to launch a massive counteroffensive against the gathering forces of the Ruinous Powers, there was no doubt that Katarinya Greyfax would stand at his side and face the enemies of the Emperor.
