Chapter Master - Crimson Slaughter: Kranon the Relentless - Once known as Sevastus Kranon, Kranon the Relentless is the current Chapter Master and Chaos Lord of the Crimson Slaughter warband of Chaos Space Marines. Kranon was known to be militant and brutal even during the days when he was still a loyal servant to the Emperor as the Chapter Master of the Crimson Sabres Chapter. Upon leading his warband into self-imposed exile in the Eye of Terror, Sevastus was corrupted by the Ruinous Powers of Chaos. Renaming himself Kranon the Relentless, he has driven himself to commit more and more bloody and vile acts in an attempt to silent the maddening voices that plague him, the result of a "gift" from the Blood God Khorne.Drabek - Drabek was Chapter Master of the Crimson Sabres sometime during the 39th Millennium. Despite the heroics and their many instances of sacrifice, then Chapter Master Drabek became increasingly convinced that the reputation of his Chapter was in question. To those on far-off Terra, this was not the case –- for the Crimson Sabres were amongst the most highly decorated forces that participated in the campaigns in the Segmentum Tempestus. To those who fought alongside them, however, Drabek's assessment was accurate. Many allies were growing frustrated with the highly critical and overly suspicious nature of the Crimson Sabres Chapter.Arnoc - Arnoc assumed command of the Crimson Sabres upon the death of Nigellus in 599.M38. Arnoch succeeded Nigellus as Chapter Master of the Crimson Sabres, but the new traditions he had established lived on. If anything, the Chapter became yet more fervent and exacting in its strict adherence to orders. Arnoch became known as the Intransigent –- a title that would be used to describe all the Chapter Masters that followed. In one of his first acts, Arnoch the Intransigent sought to further banish their hidden past, wary of how others might judge the Chapter. He made the decision to seal all entrances to the Sanctum of the Sword, located within the Chapter's fortress-monastery. Not only did it lock away evidence of a perceived imperfection, but it was also his declaration that the past was over and a new era begun.Nigellus (KIA) - Nigellus was the Chapter Master of the then-Loyalist Crimson Sabres in the mid-38th Millennium. When the Crimson Sabres received words of censure from Terra for their actions during the Amalgamathian Schism for breaching unspoken protocol, Nigellus was determined to shed his Chapter's growing self-doubt and make a statement. In a bold move, he declared the Crimson Sabres would sever all ties to their brother Space Marine Chapters, including their founders. They would be loyal to the tactical guidelines laid out by the Codex Astartes and follow uncompromisingly all orders as issued by the High Lords of Terra. To all others, they would be unanswerable. In this action, he sought to free the Crimson Sabres from faulty judgement and therefore all reproach. When self-doubt began to gnaw at many within the Chapter, Nigellus ordered to scrub clean all evidence of their forebears and the Chapter's full history was locked away. Years later, while suppressing a rebellion over the Hive World of Fornstadt, the Crimson Sabres become embroiled in a brutal clash with Chaos Cultists. Master Nigellus was slain in his 112th year as Chapter Master -– his last action was to expose the source of the rebellion, which rested with the Alpha Legion.
