While the Chapter has served throughout the galaxy, they have made the Loki Sector their primary base of operations for millennia. As the sector has been dominated by Orks since humanity first encountered the region, the Crimson Fists have engaged in countless wars with these savage xenos. Though they are not specifically devoted to overcoming these foes, the Chapter's battle-brothers are well versed in Ork psyche, physiology, and tactics. The near-constant supply of Ork warbands in the region makes this training necessary and profoundly useful. As this ability has become associated with the Chapter, the Adeptus Administratum and even the Inquisitorial Ordo Xenos have often requested assistance from the Crimson Fists when significant Ork forces gather throughout the Imperium. Miracle of the Blood - A sacred ritual that is observed b For unknown reasons, in the last century of the 41 st Millennium, the Soul Drinkers were declared Excommunicate Traitoris and all records of the Chapter were destroyed by an Inquisitorial Edict of Obliteration. Somehow these Renegade Space Marines escaped destruction.

And should I choose not to do so?" Kantor asked, for he could not bring himself to place his trust in the elaborately helmed alien, now revealed as a warrior of the Aeldari race, that stood before him.When the forces of the Indomitus Crusade entered orbit above Rynn's World, they brought more than just reinforcements to the Crimson Fists -- they brought a future and not a small degree of hope. From Archmagos Dominus Belisarius Cawl's freighter-hulk Zar-Quaesitor, a new generation of Crimson Fists -- the Primaris Space Marines -- joined the fray. Crimson Fists Chapter Colour Scheme as displayed by a Firstborn Space Marine. Foundation and Crusades The Crimson Fists are often on the move, no longer having a true home base and reverting to their ancient practice of operating as primarily a fleet-based Chapter. Yet, they often return to Rynn's World to mourn the battle-brothers who died so heroically in its defence. Brothers, today we have come to reclaim that which is ours and defend the Imperium as the primarch instructed. Show these greenskins no mercy, for they are nothing but a pox upon the galaxy." The Lord Commander of the Imperium, the newly resurrected Primarch Roboute Guilliman, launches his Indomitus Crusade

In the aftermath of the tragic conflict known as the Horus Heresy, Roboute Guilliman, the primarch of the Ultramarines Legion, penned his sacred manual of warfare, the Codex Astartes. With the creation of this tome, Guilliman demanded that his brothers accept his example by dividing their own Space Marine Legions into 1,000-member Space Marine Chapters so that no single commander could ever control the power of an entire Astartes Legion again. The planet is sparsely populated, mountainous, and devoted to intensive agriculture, with its principal export being jadeberries, an exotic fruit native to the planet. Rynn's World possesses one major conurbation (New Rynn City) and eight smaller cities plus small farms and agricultural centres (1,468 facilities according to most recent Imperial census). It was a difficult campaign, for the Orks defended every crag and cavern, and Kantor had neither the men nor the equipment he would have wished for such a task. Nonetheless, the Crimson Fists forged on, slaying Greenskins wherever they could be found. The Chosen - The Chapter's Serfs are made up of failed Astartes Aspirants collectively called "The Chosen", who serve the Chapter in multiple combat support roles. It is from these Serfs that messengers, skilled labourers and even the Chapter Master's Major-Domo are all drawn.

Rynn’s World

Chapter Master Polux reorganised his battle-brothers in a format that followed closely with the structure proscribed by the Codex Astartes. However, he continued to follow many of the tactics and traditions that he had learned at the hand of the primarch as a member of the Imperial Fists. These men make sure that the Deathwatch has its due and many within the Crimson Fists are seconded for service, an arrangement which benefits both the Chapter and the Ordo Xenos. The result is that Crimson Fists have both great pride for their place in the Deathwatch and a great responsibility to live up to the Long Vigil's expectations. This can sometimes grate with the other members of a Crimson Fists Astartes' Kill-team as the Space Marines of other Chapters consider them aloof and entitled, as if the right to wear the silvered shoulder plate of the Deathwatch was always their due and not something to be earned only through glory and death. The Crimson Fists are noted for having an extensive calendar of sacred days to honour the Emperor and their primarch as well as practising a number of traditions and rituals unique to their Chapter:
