Deathwing - Pre-Heresy: Holguin - One of the few Terran-born members of the Ist Legion to hold a place in the Council of Masters of the Hexagrammaton, Holguin was a key member of Lion El'Jonson's council. During the long years of the Great Crusade, he was renowned for his unwavering loyalty and determination in battle. This grim resolve saw him survive confrontations that few others could, and he was one of a handful of Space Marines that could claim to have fought in all three Rangdan Xenocides and lived. In the later years of the Horus Heresy, the actions of his own primarch and the sins of the Traitors would bring a dark aspect to his demeanour, leaving him prone to a bitter fury. Once Holguin stood at the forefront of the Legion's battles, however, with the coming of the Lion and the great changes wrought within the Ist Legion he had become more withdrawn. It was only with the outbreak of the Horus Heresy and the perfidy of those that would spurn their oaths of loyalty to the Emperor that he had once again thrown himself into the front lines. Some among his brethren called his nearly-rekindled zeal self-destructive, but few could deny that the fury he directed at the Traitors was a blessing for the Loyalist cause.Knight-Praetor Kordray Mordred - Kordray Mordred served as commander of the 51st Chapter of the Dark Angels, the Sable Griffons, during the Great Crusade and the early years of the Horus Heresy. This Chapter was comprised of approximately 1,500 Legionaries. Following the end of the Rangdan Xenocides, little remained within the Rangda System, save Advex-Mors, believed to be the homeworld of the xenos species known as the Rangda, upon which a chantry station of the Order of Broken Claws was erected. One of the smallest of the Orders Militant of the Hekatonystika, this cadre of warriors held the only full and complete accounting of that war and the the Rangda and, in the wake of that xenos strain's destruction, these knights were charged with guarding the spoils of those victories. The Order of the Broken Claws were charged to act as watchmen over the remains of the Rangdan home and to stand sentinel over the far reaches of the Emperor's domain. In 006.M31, a Sons of Horus Heavy Cruiser Conqueror's Pride translated in-system and hailed the Dark Angels garrison on Advex-Mors, indicating that they needed to resupply. Unaware of the treachery that had occurred on Isstvan III, there was no immediate cause for alarm. Queries from the Dark Angels requesting their destination and intent were ignored, and when Knight-Praetor Kordray Mordred demanded to speak with the Sons of Horus commander, his only answer was a sudden and indiscriminate barrage launched by the cruiser in orbit. Though the barrage left little of the fortifications on the surface, the Order of the Broken Claws' chantry below the surface only sustained minor damage. The Sons of Horus launched an entire Chapter's worth of Legionaries upon the surface, including a formation of elite Justaerin Terminators. Within the stygian darkness of the corridors of the Broken Claws chantry, the warriors of the Ist Legion broke the pride of the Sons of Horus, inflicting heavy casualites upon their foes. When the Traitors finally managed to breach the inner chambers they were greeted with the sight of a slew of corpses of their own warriors, with very few Dark Angels bodies amongst them. With their honour besmirched, the Sons of Horus launched a series of successive assaults. But these only resulted in more of their warriors being slain by the stubborn Dark Angels defenders. Finally, with only one surviving defender, the Sons of Horus sent their Destroyer squads to finish off the stubborn Dark Angels once and for all. With the death of the final defender, the Sons of Horus broke into the stasis vault that contained the forbidden Rangda weaponary and proceeded to plunder a number of pre-determined weapons and fled for the surface. However, one of the grounded Traitor Stormbird gunships was captured and the relics it bore lost to a daring assault by Knight-Praetor Mordred and his Deathwing lifeguard, while another was shot down and destroyed by Ravenwing Xiphon Interceptors. However, despite their efforts, the surviving Sable Griffons were unable to halt the Traitors' exodus from the surface. Though the remainder of the Dark Angels defenders were trapped beneath the surface, the Sons of Horus were unable to take their revenge and were forced to flee due to the arrival of Dark Angels reinforcements in the form of the Promethean-class Cruiser Invidious. Though the Sons of Horus had achieved their primary objective and managed to acquire some of the Rangdan weapons, they were unable to break the will of the fiercely Loyalist Dark Angels, achieving only a phyrric victory at best. Ultimately however, the potency of these forbidden weapons would help turn the tide of the Horus Heresy in the Traitors' favour.Knight-Sergeant Indravain Mors - Knight-Sergeant Mors was a Seneschal of the Deathwing, assigned to the 23rd Order, "The Shattered Mantle", during the Great Crusade and Horus Heresy. Indravain was inducted into the inner circle of the Deathwing after the battle on Mykana, where he took a Mykanan phase-lock musket shot meant for his commander, leaving him on the brink of death once victory was secured. His armour bore a number of elements of the unique heraldry used by the Dark Angels, often considered indecipherable by their brethren in the other Legions. Knight-Sergeant Mors would fall again on the fields of Sheol IX, once again shielding the knight-praetor of the Shattered Mantle, though this time from the vengeful talons of the Night Haunter himself. His shattered body was recovered from the field of battle and interred in a cybernetic Dreadnought sarcophagus in honour of his sacrifice.
