Garviel Loken - Luna Mendax: Having failed in their mission, Loken returned to the Somnus Citadel on Luna, the fortress-monastery of the Silent Sisterhood. Already appraised of the mission's outcome by astropathic means, the Primarch of the Imperial Fists had, nevertheless, taken time from the dismantling of his father's bejewelled palace in preparation for the coming invasion of Horus to hear the ill-news from Caliban first-hand.Loken had seen Rogal Dorn's hope that the imperfect medium of astropathic communication had missed some subtle nuance to Qruze's report, some sign that the Lion's warriors of Caliban could be counted on to rally to the Emperor's banner. Dorn would return to Terra none the wiser, and Loken's heart had broken at disappointing him.Loken had no time for the Sigillite's half-truths and subterfuge. He no longer wanted a part in his schemes within schemes. Though Loken had survived the horrors he experienced on Isstvan III, he was a man whose sanity was just a mask to cover the real horror of what was going on underneath the surface. After Caliban and the disastrous attempt to learn the Dark Angels' true allegiance, Loken retreated into his own little world of isolation, but the first cracks in what others believed to be his sanity started to show when he saw his former battle-brother Tarik Torgaddon.Loken had taken to spending most of his time within an abandoned and disused lunar biodome. The previous custodian of this biodome had allowed it to grow wild, neglecting the task of prudent weeding and maintenance. He later learned that it was the former domain of a Silent Sister, long dead on Prospero, and no one had taken up her duties in the biodome, as the maintenance of a space that existed as purely aesthetic was seen as wasteful.He devoted his time to tending to a small garden. Bred to kill, not to care, it gave Loken a sense of the wonder of creation. It also gave him a small sense of peace, as he was a warrior born and bred, wrought in the Emperor's gene-labs. That word, peace, was meaningless to him, for as far back as he could remember, he had never known any state of being that could equate to the concept. The madness that almost consumed him on Isstvan III had left scars that were slow to heal and quick to flare in jagged pain.Loken had found the biodome by chance, staring vacantly through the armourglass window of the orbital shuttle bringing him back to Luna. He had spent the journey back from the Caliban fiasco in contemplative silence, isolating himself from the crew of the nameless vessel that crept into the Dark Angels domain before slinking away like a thwarted thief.The abject failure of the mission weighed heavily on Loken, and he had struggled with his part in it through the long, cold nights in the dark heart of the vessel. He was a warrior who had turned his back on war, a man without colours or a Legion to call his own. In the depths of his despair, he had believed himself to be a Legion of one. Nathaniel Garro had shown him that that was no longer the case. He no longer fought alone, but he cared nothing for the warriors who stood with him. The brotherhood of his former life was no more than a ghostly memory now.One day, while tending to his garden, he was visited by a mysterious individual. He had the bulk of a Legionary, though Loken couldn't immediately recognise who he was, though his appearance was maddeningly familiar. A cold hand clenched Loken's hearts as the man's previously unknowable features resolved into those of a brother from a previous life -- it was his long dead battle-brother, Tarik Torgaddon. At first Loken believed that this so-called "Torgaddon" was a figment of his imagination -- some memory his damaged mind had conjured up.But as Loken continued to talk to him, the more he was convinced that it was indeed his old friend. Torgaddon helped unlock the forgotten memories from Loken's fractured synapses. As Loken looked upon the garden, he recognised it for what it was -- it was a replica of the water garden where he had taken the Mournival Oath. Torgaddon reminded him what he had pledged when he had sworn this sacred oath -- to serve the Emperor above all Primarchs. To uphold the truth of the Imperium of Man, no matter what evil assailed it. To stand firm against all enemies, alien and domestic.Loken had sworn to be true to the ideals of the Mournival. He was nearly overwhelmed by the surge of suppressed memories. Loken remembered it all -- the war on Murder, the blood spilled from misunderstanding upon the homeworld of the Interex; the horror of Davin; the slaughter of the Auretian Technocracy; and the final, monstrous betrayal on Isstvan III. He'd known all this, he'd always known it, but had found a way to keep it locked away in the depths of his mind. But no matter how hard he had tried to forget, he was unable to.Togaddon reminded him that he was a Luna Wolf, and nothing was more dangerous than a cornered wolf. A man might have control of action alone but he never had control over the fruits of that action. He told Loken to take control of his actions. Before he departed, Loken inquired to Torgaddon whether or not he was real, to which the other Legionary couldn't easily answer.Torgaddon didn't have an explanation -- he felt real, but he thought that something terrible happened to him after he died. Loken inquired what could be worse than dying. Torgaddon didn't know yet, but he was sure that Loken was the only one who could undo it. After imparting his warning, Torgaddon departed.Soon, Loken was approached by another visitor, this time, one of his fellow Knights-Errant, Iacton Qruze. He brought a summons from Malcador himself. Reinvigorated by Torgaddon's visit, Loken was ready to depart to undertake whatever was required of him.Essentially, Torgaddon's visit had shocked Loken back into reality, restoring a final sense of himself as wounded, but not broken. Though he went to Terra to meet with Malcador, deep down Loken still worried that the damage wrought to his mind left him untrustworthy. But he was still willing to serve to the best of his ability, and prepared to receive his next mission from the Sigillite.
