Blackshield Reaver Lord - Notable Blackshield Reaver Lords: Endryd Haar - Known as the "Riven Hound," Haar was once a World Eater. Both he and his command were believed long-lost on Crusade when his brethren cast in their lot with the Traitors. Endryd was driven to cold madness by the revelation of his Legion's betrayal when he returned to find the Imperium riven by civil war, and he cast off all traces of his Legion's insignia and honours and swore a Death Oath to atone for the XIIth Legion's crimes. Leading a Blackshield unit known as "The Fangs of the Emperor," Endryd Haar fought alongside the Loyalists as a field commander in the dark days before the Siege of Terra, accepting any mission -- whatever the odds of survival -- so long as in doing so he could spill the blood of the enemy.Crysos Morturg - Section Leader Crysos Morturg was a bitter warrior, morbid and given to introspection. He was disliked by his Battle-Brothers despite his evident talents as a warrior and field commander. He was neither Terran nor Barbaran by birth, having been inducted into the Death Guard Legion during an emergency influx of recruits from the induction pool of the 18th Expeditionary Fleet after the Death Guard suffered near-catastrophic losses during the Rangdan Xenocides campaign of the Great Crusade. Years after his induction, after he rose to the rank of Lieutenant, his latent psychic abilities manifested. This only served to further isolate him from his fellow Astartes, and he had barely begun his training within the Legion Librarius when Mortarion had it disbanded and ordered such "witchcraft" suppressed. Morturg was reassigned to the Legion's Destroyer Corps and was often given Legionaries judged to be fractious or unstable, and his unit was tasked to the brunt of the worst fighting the Death Guard endured. During the campaign against the Traitor Legions' Loyalists on Istvaan III at the start of the Horus Heresy, he was marked for death as a Loyalist and sent to the surface on the doomed world. But Morturg did not die and instead endured, rising to become one of the most deadly commanders of the Loyalist resistance. Despite all the odds, Morturg survived the atrocity on Istvaan III and he and the few remnants of the slaughtered Loyalists he had gathered to him would live to avenge themselves upon their former brethren.The Nemean Reaver - This unknown Blackshield Reaver Lord fought throughout the middle years of the Horus Heresy, leading the Blackshield band known as the Dark Brotherhood against numerous foes as he sought to carve out a haven within the Eridayn Cataract. He garnered a reputation throughout the Pale Stars, and was often referred to simply as the Nemean. It is generally believed that he was once an officer of the Ist Legion -- the Dark Angels -- though even this was far from certain. Unconfirmed rumours circulated that he was a survivor of the Rangdan Xenocides, the apocalyptic conflict that saw the nascent Imperium threatened with destruction during the Great Crusade, and he had already entered into the legends of the Legiones Astartes long before the Horus Heresy. At the Conclave of Optera, he renounced his position and departed with Nathaniel Garro, Knight-Errant of Malcador the Sigillite, for Terra, leaving his lieutenants to take command of the Dark Brotherhood and lead it as they saw fit. It is believed his duty to the Sigillite culminated at the Battle of Terra upon the walls of the Imperial Palace during the very climax of the Horus Heresy.Nuhmarak - Nuhmarak, the so-called Crippled King of the Void, was a darkly brooding warrior-lord, bitterly resentful of the fate that had befallen the galaxy.
