Garviel Loken - Personality: Loken was an unusually thoughtful, calm and rational Space Marine, referred to as "the quiet one" of the Luna Wolves' Mournival by Horus. While not a man of many words, he often surprised those around him with the depth of his mind and character, unexpected in one who had been bred for war.Like most of the members of his Legion, Loken was a native of Cthonia, the ancient Mining World near Terra where Horus Lupercal had been rediscovered by the Emperor of Mankind in the early days of the Great Crusade. Unlike his fellow Astartes, Loken spent a great deal of his time reading and studying ancient writings, such as the Chronicles of Ursh. These were loaned to him from the vast Librarium of ancient Human texts aboard the Luna Wolves' battle barge Vengeful Spirit by his friend, the Iterator Kyril Sindermann.It is the insights gained from this study that enabled Loken to see the corruption of Chaos for what it was as it took hold of Horus and most of the Sons of Horus Legion around him. It was his devotion to the truth at all costs, and his loyalty to the Emperor that ultimately placed him at odds with those who followed Horus into darkness.Loken had many friends within the XVIst Legion as well as outside it in the days before the start of the Heresy, an unusual quality for an Astartes, as the Space Marines of the Luna Wolves rarely took notice of the normal men and women many of their kind routinely dismissed as "mortals." He befriended the Remembrancers Mersadie Oliton and Ignace Karkasy.Oliton, a writer, followed Loken and often met with him in his personal armoury to record the takes of his experiences in battle. Karkasy was a poet who, after landing in trouble with the Imperial Army and nearly being beaten to death for openly speaking his mind about the potential immorality of the Great Crusade's conquest of human worlds, caught Loken's attention.Loken respected him for his unusual willingness to speak the truth even when he did not agree with his conclusions and the Luna Wolf captain sponsored him, allowing him to remain with the 63rd Expeditionary Fleet. Loken protected Karkasy, even when Karkasy's poetry became openly critical of the Astartes.Another important figure in Loken's life was Kyril Sindermann, who as an Iterator was a member of the corps of Imperial propagandists who accompanied each Great Crusade Expeditionary Fleet to carry out the cultural incorporation of conquered human worlds into the Imperium by spreading the Imperial Truth. Loken often pursued in-depth discussions on a variety of intellectual topics, including religion, with Sindermann.Religion had been dismissed as mere superstition by the rationalism of the official creed of the Imperial Truth. This association, along with his protection of the Remembrancer Ignace Karkasy, later led to strife for Loken with Horus and his Warmaster's new confidante, First Chaplain Erebus of the Word Bearers Legion.The Warmaster, often manipulated by the long-corrupt Erebus, turned against all the Remembrancers accompanying the 63rd Expeditonary Fleet shortly before the Isstvan III Atrocity. He believed them to be of little use in his coming war against the Emperor, particularly as they began to tell the truth about the corruption induced in the Legion by Chaos.For this reason, once the Loyalists were on Isstvan III and could no longer protect them, Horus has his Astartes execute all the Remembrancers in the Sons of Horus fleet. Sindermann would survive and escape to the Eisenstein with the aid of Iacton Qruze, and would himself later become one of the founding members of the Inquisition.
