Blood Drinkers - Notable Blood Drinkers: Chapter Master Orloc - Current Lord of San Guisiga and Chapter Master of the Blood Drinkers in the late 41st Millennium. Orloc is known to be a pious and respectful Space Marine.Chapter Master Radin Castor - Lord of San Guisiga and Chapter Master of the Blood Drinkers. Radin Castor was the successor of Chapter Master Caedis. Before taking the mantle of the Blood Drinkers Chapter Master, Radin Castor was a Captain of the Blood Drinkers 1st Company. Castor won the Mastery of the Chapter by defeating his fellow Captain Sorael of the 5th Company. Castor was the last man standing, as well as the one who whistood the Red Thirst.Chapter Master Caedis (Deceased) - Lord of San Guisiga and Chapter Master of the Blood Drinkers in the 39th Millennium, he personally led a large strike force comprised of Blood Drinkers to fight alongside the Novamarines Chapter in a ferocious assault on the Genestealer-infested Space Hulk Death of Integrity. During the height of the fighting, the genetic curse known as the Black Rage came upon him, and he was overcome with visions of Brother Holos. During the subsequent fighting, as the Blood Drinkers 1st Company cleared their assigned sector of any Genestealer taint, his sense of reality was obscured by visions of Holos' trials during his ascent up Mount Calicium to reach its summit. On the edge of perception, Caedis passed through deeper and deeper into the Space Hulk in Holos' fugue. While in this fugue state, Caedis experienced reaching the summit of the volcano, and saw the indistinct vision of a mysterious entity that his mind could not quite grasp. As he conversed with this mysterious entity that claimed to be his Chapter's salvation, a sense of terrible horror gripped him as he realised that it was not an angel that he spoke with, but a Daemon of Chaos! All Space Marines had some knowledge of the Ruinous Powers. Few among their number were fully aware of the Dark Gods' actual influence on the material universe, or the nature of their servants, or how those servants could manifest themselves. But Caedis knew, for he was a Chapter Master, and thus the most awful secrets of the universe had been laid open to him. Caedis refused the Daemon Lord's offer, willingly suffering the torments of the depths of the Black Rage. The Daemon Lord warned the Chapter Master, that though he may defer his fate, those like him would continue to follow Holos in his trek up the mountain. They would fight, and they would struggle, and they would come to the Daemon Lord. Many would say "no", but inevitably one would say "yes". As promised, Caedis did indeed suffer the torments of the Black Rage, his body transforming into a monstrous form. Before the Novamarines that were present could inquire to the Chapter Master's transformation, they were forced to flee, as the sentient Death of Integrity translated into the Warp, taking the mutated Chapter Master with it. Caedis met his demise in an unknown circumstances. His successor was Captain Radin Castor of the Blood Drinkers 1st Company.Chapter Master Ganlan Sang - Lord of San Guisiga and Chapter Master of the Blood Drinkers in the 37th Millennium, during the Chapter's darkest days when it waned dangerously close to extinction. The genetic curse of the Flaw seriously affected the Chapter's Battle-Brothers and a large proportion of their warriors fell into the throes of the Black Rage and were placed within the Death Company. At that time the savagery of the Chapter's large Death Company and the constant desire for death and sacrifice to sate the Thirst bedevilled every brother, their stoic resistance burned away in a cloak of insatiable bloodlust.Captain Carnifus - Captain Carnifus was the commander of the Blood Drinkers' 3rd Company prior to the Devastation of Baal and was among the forces sent to reinforce the Blood Angels in the face of Hive Fleet Leviathan's assault on Baal. It is unknown whether he survived the siege.Captain Sorael - Sorael was the Captain of the Blood Drinkers 5th Company.Holos - Holos is an ancient Chapter hero, revered by the Blood Drinkers as a saint -- the one who delivered the nearly extinct Chapter the secret to surviving the ravages of the Black Rage and bringing a measure of peace to the Blood Drinkers and saving them from damnation. By the 37th Millennium, the Blood Drinkers was a dying Chapter, brothers succumbing to the Black Rage as soon as they were fully initiated. The hero-saint Holos had set out after a dream, disobeying the will of the Chapter Council to fulfil his quest. Holos had experienced a dream, and after being secretly counseled by Reclusiarch Shanadar, had set out on his sacred journey to climb Mount Calicium, the mightiest volcanic peak on his Chapter's homeworld of San Guisiga. As the brave Battle-Brother climbed the nearly insurmountable peak, he battled Lo-tan, the lord of the astorgai -- vile xenos creatures that infested the mountain's crags. This foul creature was a great monster five times the size of his subjects. Four great heroes of the Chapter had set out to slay him, four heroes had died, their wargear and lives lost in his lair. Holos' mind was clear on the matter -- this was the only way to the top of the mountain. By the time Holos reached the summit his armour had been broken by the violence visited upon him by the astorgai. So damaged were its Machine Spirit and aiding systems that it died and its weight soon became a burden. What armour Holos could free was thrown off. One of his arms hung uselessly at his side and his weapons were gone. But Holos' will remained. As Holos lay close to death upon Mount Calicium's peak, a winged, angelic figure had appeared to him, reviving him at the point of his death and giving him the secret that would enable the Blood Drinkers to keep the Thirst at bay, if they dared -- and Holos dared. Brother Holos had returned solar weeks later to the fortress-monastery on San Guisiga, long after he had been given up for dead. Celebrations at the hero's return turned to uproar when he revealed what he had been told. What the winged figure proposed nearly tore the Chapter in two, but those were desperate days, a time when more and more Battle-Brothers were falling into the Black Rage with every passing year, and the Thirst tormented them endlessly. Any measure to alleviate it was attempted, all without success. These two events are known in the Chapter's histories as Holos' Return and the Blood Schism. Holos' solution, the rite and the way of being he brought back with him from the summit of the volcano, soon worked, putting an end to the demands of the Red Thirst and the madness of the Black Rage. The Blood Drinkers have since known an equilibrium that the other scions of Sanguinius could only pray for. The Rite of Holos is the Blood Drinkers' greatest secret and their greatest strength. Without it the Chapter would have descended into savagery and been lost. With it, the brothers remained stalwart defenders of the Imperium. There was, however, a terrible cost, which may yet damn the Chapter for all eternity.Epistolary Guinian - Epistolary of the Blood Drinkers.Reclusiarch Mazrael - Chapter Reclusiarch and successor of Quiniar.

It was his counsel that Brother Holos first sought when he began to experience the first signs of the Black Rage. Sharing his vision of the angelic entity upon the summit of Mount Calicium, Shanandar colluded with Holos, advising him to seek out the truth of this vision. After Holos returned from his quest, he shared the whole truth with the Reclusiarch about the Rite and the Daemon whom he spoke with. From that time forth, the Chapter's Reclusiarch passed down the truth of Holos' "vision" to each successive Reclusiarch, the truth of the Rite their burden to bear.Forgemaster Quaeston - Forgemaster Quaeston was the Blood Drinker's Master of the Forge prior to the Devastation of Baal and was among the forces sent by the Blood Drinkers to reinforce the Blood Angels in the face of Hive Fleet Leviathan's assault on Baal.
