Imperial Fists

The Imperial Fists are one of the First Founding Chapters of the Space Marines and were originally the VII Legion of Astartes raised by the Emperor Himself. They stand out from other Space Marine Chapters since they possess no fixed homeworld, although they are most frequently based on Terra. Instead, the Imperial Fists rely on their 10,000-year-old mobile space fortress, Phalanx, to serve as their fortress-monastery. They maintain recruitment-chapels on various worlds spread throughout the Imperium. Part of the Imperial Fists' duties during the Great Crusade were to function as the Emperor's "personal praetorians", accompanying Him everywhere. The Imperial Fists were usually used to strike a decisive blow against the enemies He confronted during that time. The role of the Emperor's bodyguards since he was mortally wounded during the Horus Heresy and interred within the Golden Throne at the heart of the Imperial Palace on Terra has been entirely taken over by the Adeptus Custodes.

Chapter History
The Imperial Fists' Primarch was named Rogal Dorn and is usually regarded as having been the most level-headed and fair of the Primarchs, although in the view of the Imperial Fists' great rivals, the Iron Warriors, he was arrogant and spiteful. The Imperial Fists were one of the three Space Marine First Founding Legions who defended the Emperor of Mankind's Imperial Palace during the Horus Heresy. In fact, it was only due to the intervention and self-sacrifice of a squad of Imperial Fists Terminators that the Emperor was able to strike down Horus. It was Rogal Dorn who discovered the bodies of the Emperor, Sanguinius and Horus, receiving the last words of the Emperor, instructing him to build the Golden Throne in the Imperial Palace which sustains him to this day in a state neither alive nor truly dead.

The Imperial Fists, like the Iron Warriors, were the siege masters of the First Founding Legions and as such rely greatly on artillery and the use of heavy weapons in combat, although not to the extent of their traitorous former brethren among the Iron Warriors. These two rivals' shared specialisation led to a great rivalry and eventually hatred between the two Legions and their Primarchs, and after the Heresy the Imperial Fists continued to pursue the Iron Warriors for some time, culminating in the battle of the "Iron Cage" -- which essentially ended in a stalemate broken by the arrival of the Ultramarines.

After the Horus Heresy, the Imperial Fists were broken up into separate Chapters, as were the other remaining Loyalist Space Marine Legions, and their more notable Successor Chapters include the Crimson Fists and the Black Templars. The Imperial Fists, however, were among the slowest of the Chapters to co-operate with the tenets of the Codex Astartes written by the Primarch of the Ultramarines, Roboute Guilliman.

Great Crusade
The Imperial Fists were first formed on Terra, as shown by their earliest battle honour, "Roma." The Imperial Fists Legion had heavily recruited from the Ice World of Inwit with over 70% of the Legion's strength having come from that frigid Hive World when Rogal Dorn joined them. This means that the Legion was relatively young when it was united with its Primarch, allowing them to form an unbreakable bond, based upon their similar desires for self-discipline and total commitment to the spread of Order. The few Battle-Brothers of the Imperial Fists who originated on Terra brought with them a tradition of honour duels, practiced even to this day. No one knows where or when this form of combat originated, but it served to bond the warriors together by giving and receiving honour while maintaining their Terran heritage.

After the Imperial Fists won a major victory against the Orks on the ash wastes of the hive world of Necromunda, the Hive Lords consented to recruits being drawn from their population in gratitude. A Fortress-Chapel was duly consecrated but the Imperial Fists were there as esteemed guests, not masters. Rogal Dorn asked no special rights on the worlds where the Fists recruited. Some Primarchs, such as the increasingly mercurial Perturabo, took every opportunity to garrison a world for their Legions and claim its tithes. Dorn is famously recorded as saying "I want recruits not vassals," and was always satisfied to keep his Legion as a military unit with none of the civil responsibilities that came with governing a Legion homeworld.

During the Great Crusade, the Imperial Fists acted as the strategic reserve of the Emperor's forces due to their ability to rapidly redeploy to battlefields aboard Phalanx. They made use of detailed planning and as such were soon found to be supreme urban fighters and siege specialists. After several campaigns and thousands of conquered worlds being brought into the Imperium, the Emperor returned to Terra to build a capital from which he could run His new empire. He took the Imperial Fists with Him, set them up as his praetorians and charged Dorn with the construction of the Imperial Palace, something that didn't go unnoticed by the other Primarchs. Perturabo flew into a rage upon hearing that Dorn thought the Imperial Palace would be proof against an assault by even as mighty siege-masters as the Iron Warriors and he unleashed a torrent of vitriol and accusations against his brother Primarch so unfounded that the onlookers from his own Legion were dumbstruck. After this outburst was reported to Dorn, the two Primarchs rarely spoke, neither Legion serving in the same campaign again. The Imperial Fists were ever at the Emperor's side and the Iron Warriors were part of Horus' vanguard.

Mission To Mars
For those still loyal to the Emperor on the Red Planet, their salvation arrived in the form of a great Imperial expeditionary fleet. Malcador the Sigillite, the Regent of Terra, charged Rogal Dorn with a mission of the most vital importance- to secure the forges of Mars for the Imperial war effort. Dorn informed the Sigillite that he would send his Legion's Champion and First Captain Sigismund, 4 companies of Imperial Fists and a large force of Imperial Army soldiers to secure the forges of Mars. Within the northern hemisphere of the Red Planet lay an arc of Loyalist control—the important munitions manufactorums of Mondus Gamma and Mondus Occulum. Within these two vast industrial complexes the Mechanicum fabricated the weaponry and Power Armour for the Legions of the Space Marines. The forges of Mondus Occulum and Mondus Gamma alone produced the bulk of the armour and weapons of the Astartes. Dorn intended for his force to strike there and capture those forges and once they were occupied, the Imperial Fists and their allies would push outwards and secure the others.

Sigismund's companies landed at Mondus Occulum as the rest of the Imperial expeditionary force was fighting all across the surface of Mars. After a rapid deployment under fire in the shadow of Pavonis Mons, 13 companies of the Imperial Army's Saturnine Hoplites advanced on the Traitors' lines surrounding the forge of Ipluvien Maximal. Further south, 2 of the companies of Imperial Fists and 4 regiments of Jovian Grenadiers (nearly 15,000 Imperial Army soldiers in total) under the command of the Imperial Fists' Captain Camba-Diaz made planetfall in the Mondus Gamma forge complex.

Nothing of the Imperial Fists' mission to Mars panned out the way it had been expected. Camba-Diaz and the Jovian regiments soon became embroiled in a fight for their lives at Mondus Gamma forge, and the Saturnine Hoplites companies tasked with breaking the siege at Ipluvien Maximal’s forge had been repeatedly turned back by the horrifyingly altered weapon-creatures of the Dark Mechanicum. Though the fighting was desperate, Camba-Diaz eventually secured the armour forges and the ammunition silos, but his company was outnumbered a hundred to one. The Traitor Chrom’s troops pushed him back to the landing fields and his losses were grievous. Sigismund knew the Imperial expeditionary force would not be able to hold the forge, but a great deal of essential supplies had been secured for transit to Terra.

Sigismund’s companies had descended upon Mondus Occulum not knowing whether they would have to fight to secure the forge, but it was a relief to find that Fabricator Locum Kane still held true to the Imperium. Sigismund secured vast quantities of munitions for transport back to Terra, including nearly 12,000 suits of Mark IV Power Armour and twice as many Astartes weapons. But the Loyalists had run out of time. Despite the locum's Servitors working at full capacity, it still was not rapid enough, for Sigismund's ship masters informed him of a sizable enemy force closing in, composed of infantry, armoured vehicles, Skitarii and at least two  Traitor Titan Legions] comprising nearly 60 war engines in all. Sigismund's desire to wreak a bloody vengeance on the heads of those who had rebelled against the Emperor warred with the necessity of the mission his Primarch had given him to secure the vital armour and weapons of Kane’s forge that would be needed to defend the Imperial Palace at a later date. Reluctantly he knew that he must stay true to his mission, for the forces arrayed against the Imperial strike force were simply too many and his orders did not allow for the pursuit of futile gestures of defiance. Locum Kane warned the Imperial Fists' First Captain that if both the Mondus Occulum and Mondus Gamma forges fell, the Imperium would have no way of replenishing the combat losses they would sustain in any meaningful way.

After barely a few hours worth of fighting both Mondus Occulum and Mondus Gamma were burning, with vast swathes of their industrial machinery and manufacturing capacity destroyed. The loss of such irreplaceable technology and knowledge, would be felt by the Imperium for many millennia to come. Like comets launching from the surface of Mars, the Imperial starships fled for the heavens. Astartes and Imperial Army vessels jostled in the sky in their haste to depart the Red Planet. Barely a thousand Loyalist warriors were able to escape from the planet's surface before the manufactorums fell into the hands of the Traitors. The desperate rearguard action of the Astartes and other Loyalists on Mars and the sacrifice of many thousands of lives at least had secured tens of thousands of suits of newly-fabricated Mark V and Mark VI Space Marine Power Armour and other vital materiel that would ultimately prove to be the edge for the forces of the Imperium in the campaign against the Traitor Legions of Horus Lupercal.

Battle of Terra
Along with the White Scars and the Blood Angels Legions, the Imperial Fists put up a heroic defence of the Imperial Palace from the Forces of Chaos during the Battle of Terra, that has since passed into legend. Having originally constructed the Imperial Palace, it was also Rogal Dorn who prepared the Palace's defences at the Emperor's request to face the Traitor Legions of Horus. Then, when all hope seemed lost, they accompanied the Emperor in his last battle aboard the Warmaster Horus' Battleship Vengeful Spirit. It fell to Dorn to discover the bodies of the Emperor, Horus and Sanguinius after the final drama had run its course. His grief was immense. Until that point Dorn had been true, noble and enduring, but now he became an avenging son. While the Ultramarines maintained order within the battered Imperium, the Imperial Fists hunted down the Traitor Legions, levelling fortress after fortress. Dorn led them, dressed in the black of mourning, his customary mercy set aside until the guilty were punished. While others like the Ultramarines' Primarch Roboute Guilliman shaped the new Imperium's institutions during the Reformation, Dorn immersed himself in implacable justice. It was rumoured that he saw the Emperor's death as his personal failure and his crusade as penance. After all, were the Traitors not his brothers? Whatever the cause, Rogal Dorn was absent from the highest councils until he was summoned back to Terra when Roboute Guilliman, Primarch of the Ultramarines, presented his Codex Astartes as the future of the Space Marines and the Imperial military machine.

Pillar of Bone
The Pillar of Bone is believed to be a monument raised on Terra to the Imperial Fists' courage in an unnamed campaign. But in reality it is actually a sacred holy relic to those privy to the truth within the Imperial Fists. The Pillar is the last remnant of the once-great Imperial Fists fortress-monastery on Terra. It was destroyed during the Horus Heresy in the midst of the Battle of Terra, but, to most of the huddled masses of the Imperium, the Heresy is now no more than a legend and few would dare to openly claim that the Forces of Chaos had ever set foot on the sacred ground of Terra. In the holes torn from the column by the Bolter fire of the Traitor Legions were the scrimshawed hands of Imperial Fists Battle-Brothers. Part of the sacred duties given to Imperial Fists Chaplains was to bring new relics of the Chapter to the Pillar, but at times they would also recruit those pilgrims who came to Terra from all across the galaxy into the Chapter if they were deemed worthy of becoming Aspirants. It was at this sacred site that future-Captain (and Imperial Fists' hero) Darnath Lysander was recruited after he had survived multiple misfortunes, including the slaughter of his entire family, to make it to the holy soil of blessed Terra. It seemed to the Imperial Fists Chaplain that recruited him that the young pilgrim surely had the blessings of Rogal Dorn upon him. Such intuition would be proved right again and again during Captain Lysander's career.

Column of Glory
Another of the greatest relics of the Imperial Fists Chapter also rests on Terra. Known as the Column of Glory, this structure is a massive crystalline pillar studded with the shattered armour of all those Imperial Fists Astartes who fell in defence of Terra and the Imperial Palace during the final battle of the Horus Heresy. The Column of Glory stands as an eternal testament to the sacrifice the Sons of Dorn made in defence of the Emperor of Mankind and the homeworld of humanity.

The Second Founding
After the Heresy, the Imperial Fists were broken up, as were the other First Founding Space Marine Legions, into one-thousand-man strong Chapters, and their more notable Successor Chapters include the Crimson Fists, the Black Templars and the Renegade Soul Drinkers. The Imperial Fists, however, were among the slowest of the Chapters to co-operate with the tenets of the Codex Astartes. Rogal Dorn at first refused to countenance for the splitting of his Legion into separate Chapters as required by the Second Founding, only backing down once it became clear to him that the Ultramarines, the other Space Marine Chapters and the Imperial Navy and newborn Imperial Guard would all initiate another civil war with the Imperial Fists rather than allow them to avoid accepting the dictates of the Codex. Despite his love for the Space Marines of his Legion, Rogal Dorn loved the Imperium the Emperor had created too much to subject it to another terrible conflict in the wake of the horrors of the Horus Heresy and acquiesced to the reforms ordained by Guilliman.

Iron Cage
The Imperial Fists, like the Iron Warriors, were masters of the siege and as such relied greatly on the use of artillery and heavy weapons in combat, although not to the extent of their traitorous former brethren. Their shared specialisation led to the development of a great rivalry and eventually hatred between the two Legions and their Primarchs during the Great Crusade, and after the Heresy the Imperial Fists continued to pursue the Iron Warriors for some time, culminating in the incident known as the battle of the "Iron Cage" on the world of Sebastus IV. Perturabo, the Primarch of the Iron Warriors Traitor Legion, was a master of fortification whose writings had been retained by Roboute Guilliman in his Codex Astartes. Dorn had always been Perturabo's match in the arts of siege warfare and combat engineering, and, what was more, his honest warrior's soul was indignant. The Iron Warriors had rebelled against their rightful lord and lost. Their master, Horus, was dead and the Emperor still ruled over the galaxy. Yet still they dared raise their heretical banners over another Imperial world as if they had some right to be there. Dorn would not tolerate this. Without his customary caution and planning, Dorn led his Legion into the heart of the Iron Warriors'  fortifications, a massive set of interlocking defences designed to look like an 8-pointed Star of Chaos that was known as the Eternal Fortress. The fortress was located on Sebastus IV, a world that became known in legend as the Iron Cage. The battle should have favoured the treacherous trench-fighters of the Iron Warriors, but the Imperial Fists endured. They countered every ambush and fought their way out of every trap set by the Chaos Space Marines. Rogal Dorn was a colossus who personally turned back attack after attack. Ammunition expended, the Battle-Brothers of the Fists fought in half-flooded trenches with combat knives, giving and expecting no quarter. Eventually it became apparent that the Iron Warriors could not finish them. For all their skill and ferocity, as devotees of Chaos the Iron Warriors lacked the faith to make the ultimate sacrifice that victory demanded. While they paused, the Ultramarines intervened; Guilliman had decided that Perturabo's destruction was not worth the loss of Rogal Dorn and had brought his Legion to drive off the Iron Warriors.

Cleansed by their sacrifice in the Iron Cage, the Imperial Fists immediately began their reorganisation into separate Chapters as required by the Codex Astartes. For the next two decades the remaining Imperial Fists went into retreat to rebuild their numbers, their Successor Chapters taking to the field in their stead. Dorn used this time to retrain the Chapter to embrace all aspects of the Codex Astartes. When the Imperial Fists later emerged, their adherence to the Codex was matched only by the Ultramarines.

Rogal Dorn's Death
Rogal Dorn "died" fighting onboard a Chaos Space Marine starship, after attacking the First Black Crusade fleet to emerge from the Eye of Terror under the command of Abaddon the Despoiler, with a vastly outnumbered Imperial force. Seeing the importance of attacking the enemy fleet while they were still preparing to invade Imperial space, Dorn relied on hit-and-run attacks until his reinforcements could arrive. Dorn "died" onboard the Chaotic Despoiler-class Battleship Sword of Sacrilege after leading a desperate attack on its bridge.

According to Ian Watson's now non-canonical novel Space Marine, Dorn's skeleton, without its hands, is encased in clear amber, which is formed in the shape of the Primarch's body. Dorn's skeletal fists are kept within two shrines, the bones intricately engraved with the heraldry of all the Imperial Fists Chapter's previous Chapter Masters. Only the current Chapter Master has the right to engrave his name upon the bones. Even with minuscule script, ten thousand standard years of history have left the bones covered with names, giving a list of the Imperium's greatest heroes. Each bone corresponds to former commanders of the Chapter. For instance, the left hand first metacarpal contains the names of Chapter Masters Bronwin Abermort, Maximus Thane, Kalman Flodensbog and many others, while the first phalanx of the thumb bears the name Ambrosian Spactor, and so forth.

However it has recently been revealed that Dorn and his Veteran Space Marines stormed the Chaos starship and were cut down to a man. Later, the Imperial Fists would pick up an escape pod from one of their own ships present at the battle, which contained the weapons and armour of the Primarch when he went onboard the Chaotic vessel and a single skeletal fist of the Primarch. Where the true Rogal Dorn or his body is and what his fate may have actually been, no one yet knows.

Notable Campaigns

 * First Pacification of Luna (Unknown Date.M30) - This early Imperial campaign was the first operation mounted by elements of the early Space Marine Legions beyond the skies of Terra. The Unification Wars were still raging across the surface of Mankind's birth world. Luna was the bastion of a conglomeration of resurrectionist gene-cults whose members believed that human nature was both fractal, fractured and transcendent. Each of these Selenar gene-cults clung to a different set of archetypes. Every cult member was a product of creation by the Selenar gene-wrights according to formulae crafted in the Dark Age of Technology. Resurrected in body time and time again they sought to distill the true personification of a single human archetype. In their subterranean complexes the cults were powerful, insular and resistant to the Imperial Truth. The Imperials would have normally dealt with these insular cults in the usual matter they handled all of the other Terran factions and techno-barbarian states that refused to accept the rule of the Emperor of Mankind -- by obliteration. The fact that the Selenar gene-cults had something that the growing Imperium needed complicated such action. The Selenar responded to the Imperial entreaties for alliance with silence. As the threats of the Imperium soon began to outnumber its offers, the Selenar cults began to gird themselves for war. So it was that the Emperor finally ordered Luna to be pacified by the sword, their superstitious beliefs cast down before the Imperial Truth and their gene-craft yoked to the needs of the Imperium. To this task the Emperor set three of his newborn Space Marine Legions most suited to this purpose on what some Imperial chroniclers name as the first true battle of the Great Crusade. The combined force of the VII, XIII and XVI Legions (later named the Imperial Fists, Ultramarines and Luna Wolves) lifted from the surface of Terra in a scattering of rocket flame. The as yet unnamed XVI Legion had been chosen to serve as the Space Marine force's vanguard, and had brought its full strength to bear. Cutting power to their assault craft, the Astartes of the XVI Legion drifted silently towards Luna through the void like arrows fired into the night. As the smaller wave of assault craft belonging to the VII and XIII Legions approached the airless world, the Selenar defensive weapon systems embedded in Luna's surface lashed the oncoming Imperial force. The XVI Legion's assault craft, unlooked for and unseen, struck their targets like a dagger in the night. Within six hours of the first shot being fired, Luna had been pacified and brought into Imperial Compliance, the first off-world conquest of the Imperium of Man. Faced with annihilation, the surviving Selenar cultists bent the knee instead, their surrender communique transmitted to Terra calling for the Emperor to "call off his wolves." Broken and humbled, the enslaved gene-wrights of Luna would help forge the next generation of Space Marine who would carry out Mankind's conquest of the stars. As for the XVI Legion, they had earned their name -- the Luna Wolves.
 * Pacification of Schravaan (Unknown Date.M30) - This was a joint Imperial Compliance action conducted by the Imperial Fists, Iron Warriors, Emperor's Children and the Luna Wolves Legions against the xenos Badoon on the world of Schravaan. The Iron Warriors won a great victory when they stormed the final refuge of the Badoon. They breached the defences and held while the other Legions carried the city beyond. During the following victory feast, Horus proclaimed Perturabo the greatest master of siege warfare in the Great Crusade. Fulgrim, the Primarch of the Emperor's Children then inquired to his brother Rogal Dorn whether he thought even the defences of the Imperial Palace could resist an assault by the Iron Warriors, in which Dorn replied that he regarded the defences as being proof against any assault if well-planned. Perturabo flew into a rage and unleashed unfounded accusations against his brother. After this the two rarely spoke, and their Legions would not serve in the same campaign for the remainder of the Great Crusade.
 * Pacification of Necromunda (Unknown Date.M30) - The Imperial Fists won a major victory against the Orks upon the ash wastes on the Hive World of Necromunda. The Hive Lords consented to recruits being drawn from their population in gratitude and a Fortress-Chapel was duly consecrated, but the Imperial Fists continued to refuse to accept any special rights on the worlds where their Legion recruited. Throughout the Crusade they refused to garrison or claim tithes of newly conquered worlds, instead opting to remain a military unit with none of the responsibilities that came with having a homeworld.
 * Battle of Gyros-Thravian (Unknown Date.M30) - The Battle of Gyros-Thravian was a massive joint Imperial Compliance action carried out by three Space Marine Legions, composed of the Luna Wolves, Death Guard and Imperial Fists against the extremely powerful Ork Warboss Gharkul Blackfang, one of the most powerful Ork warlords ever encountered up until that time. Despite the strength arrayed against the vile Greenskin, it was the Imperial forces who were soon on the verge of defeat. It was then that the Emperor Himself, aboard his flagship Bucephelus, came to the aid of His sons. He personally led a force composed of 1,000 Legio Custodes into the heart of the mighty Ork horde. Blackfang was confronted by the Emperor and killed atop his Gargant while the Custodians proceeded to lay waste to the rest of the Greenskin horde. The Custodians accounted for the slaughter of the Orks, slaying over 100,000 of the savage xenos, with the loss of only three Custodians. Following their momentous victory, the Emperor commemorated the Custodians' sacrifice by engraving the names of the three fallen Custodians into his own personal Power Armour.
 * Pacification of the Cheraut System (Unknown Date.M31) - This was an Imperial Compliance action during the Great Crusade jointly conducted by Astartes from the Imperial Fists, Night Lords and Emperor's Children Legions. As the Primarch of the Night Lords Legion suffered from one of his violent fits, Primarch Fulgrim rushed to Konrad Curze's aid. The Night Lords Primarch confided to his brother of the dire visions that he had seen; his death at the hands of their father, that many of the Primarchs would die fighting amongst themselves, and that the light the Emperor brought to his homeworld of Nostramo would destroy it forever. Troubled by these dire portents, Fulgrim confided in his brother Rogal Dorn. Dorn took exception to this slight on the Emperor's name and confronted Curze. Shortly thereafter, Dorn was found unconscious and bleeding with great gouges of flesh ripped away from his torso. Crouching above his fallen brother was the pallid form of the Night Haunter, weeping. Wracked with self-loathing and guilt, Curze was taken into custody and exiled to his chambers, while his brother Primarchs discussed what actions to take against their deeply disturbed brother. Hours later, when the council of Primarchs finally disbanded, they found Night Haunter missing and the Imperial Fists' honour guard watching over him butchered. By the time the Primarchs gave chase, Night Haunter had already disappeared with his Legion into the Warp.
 * Battle of Phall (Unknown Date.M31) - During the Horus Heresy, at the command of the Warmaster Horus, a large Iron Warriors contingent was sent to halt the encroaching Imperial Fists Retribution Fleet that had originally been sent to Istvaan III to reinforce the beleaguered Loyalists but, had been unable to reach its destination due to the Warp Storms created by the Chaos Gods to prevent Imperial reinforcements from reaching the Istvaan System. As such, the Retribution Fleet, containing approximately one-third of the Imperial Fists Legion's total forces, had established itself within the nearby Phall System while it waited for the Warp currents to stabilise. The Traitors could not allow such a strong complement of Loyalist Astartes to infiltrate the area of space under their control, for they could seriously disrupt preparations for the attack on Terra. Commanding hundreds of warships, the Primarch Perturabo led his fleet in a sudden and devastating attack upon the Imperial Fists fleet. Over a dozen vessels were ripped apart by the brutal hail of fire from the Traitor vessels. The Imperial Fists fought back, devastating the lead ships of the Iron Warriors' fleet, tearing them apart in a vicious firestorm. The Loyalists gained the initiative in what would be remebered as the Battle of Phall and managed to repel the Traitors' surprise attack, despite severe losses at the start of the engagement. Unfortunately, at that same time, the Retribution Fleet's Astropaths managed to make contact with Terra and received a direct order from Rogal Dorn recalling the Retribution Fleet to Terra to prepare the defences of the Imperial Palace. Launching a counterattack, the Imperial Fists drove off the embattled Traitor fleet and managed to break orbit and manoeuvre to their jump points, where they entered the Warp and made for Terra.
 * Battle of Terra (Unknown Date.M31) - After the infamous Drop Site Massacre on the world of Istvaan V, the Imperial Fists' Primarch Rogal Dorn was charged by Malcador the Sigillite to prepare the defences of Terra and the Emperor's Imperial Palace. During the closing days of the Horus Heresy, the Warmaster Horus and his Traitor Legions attacked Terra, the seat of the Emperor's Imperium of Man, in a final attempt to overthrow his father and usurp the throne for himself. During the Battle of Terra the Imperial Fists, Blood Angels and White Scars were the three Loyalist Space Marine Legions that helped defend the Imperial Palace from the hordes of Chaos. Three entire Titan Legions of the Adeptus Mechanicus and close to 2 million soldiers of the Imperial Army stood alongside the Loyalist Astartes to face the Traitors in a battle that would determine the fate of Mankind for the next 10,000 standard years. After nearly two months of constant siege, the Warmaster made one last gamble and lowered the Void Shields of his flagship, the Vengeful Spirit. Taking advantage of this opening, the Emperor, a cadre of Legio Custodes, the Primarchs Rogal Dorn and Sanguinius and a force of Imperial Fists and Blood Angels Astartes teleported aboard the Warmaster's Battle Barge. It fell to Dorn to discover the bodies of the Emperor, Horus and Sanguinius after the final drama had run its course. He returned the mortally wounded Emperor to His palace. Following the Master of Mankind's final instructions, Dorn helped inter his father within the Golden Throne, where the Emperor has sat for the last ten millennia.
 * Great Scouring (Unknown Date.M31) - Following the end of the Horus Heresy, Dorn became an avenging son. Whilst the Ultramarines Legion maintained order within the battle-scarred Imperium, the Imperial Fists hunted down the Traitor Legions, leveling fortress after fortress during the Imperial campaign of vengeance against the Forces of Chaos known as the Great Scouring. Dorn led his Imperial Fists, dressed in the black of mourning, his customary mercy set aside until the guilty were punished. Whilst others shaped the new Imperium, Dorn immersed himself in implacable justice. Rogal Dorn remained absent from the highest councils until he was summoned back to Terra when Roboute Guilliman presented his Codex Astartes as the future of the Space Marines.
 * The Iron Cage (Unknown Date.M31) - Upon the world of Sebastus IV the traitorous Iron Warriors, bitter archenemies of the Imperial Fists, laid an ingenious trap to ensnare Rogal Dorn and his Legion. Heedless of the inherent danger, the Primarch ordered the Imperial Fists to attack the Iron Warriors' Eternal Fortress—later referred to as the Iron Cage by the surviving Imperial Fists. The battle should have favoured the treacherous trench-fighters of the Iron Warriors, but the Imperial Fists endured. For all their skill and ferocity, as devotees of Chaos, the Iron Warriors lacked the faith to make the ultimate sacrifice that victory demanded. While they paused, the Ultramarines intervened; Guilliman had decided that Perturabo's destruction was not worth the loss of Rogal Dorn and had brought his Astartes to drive off the Iron Warriors.
 * 1st Black Crusade (ca. 781.M31) - Abaddon the Despoiler, the new Warmaster of Chaos Undivided, made his first attempt to launch a new offensive against the Imperium of Man following the Horus Heresy, and when he unleashed the 1st Black Crusade and the First Battle of Cadia. Rogal Dorn "died" fighting aboard a Chaos Space Marine vessel after attacking a Chaos warfleet that emerged from the Eye of Terror and vastly outnumbered the Imperial defenders. Seeing the importance of attacking the enemy fleet whilst they were still preparing to invade Imperial space, Dorn relied on hit-and-run attacks until his reinforcements could arrive. Dorn "died" aboard the Chaotic Despoiler-class Battleship known as the Sword of Sacrilege after leading a desperate attack on its bridge. When Dorn and his elite Honour Guard stormed the bridge they were cut down to a man. Later, the Imperial Fists would pick up an escape pod from one of their own ships present at the battle, which contained the weapons and Power Armour of their beloved Primarch. The only sign of Dorn was a single skeletal fist that the Imperial Fists believed belonged to the Primarch. What fate ultimately befell Rogal Dorn, and whether he truly died or not, has yet to be determined with absolute certainty.
 * The Beheading (546.M32) - The Imperial Fists participated alongside forces from the Sable Swords and Halo Brethren Chapters in the hunt for the Officio Assassinorum Grand Master Drakan Vangorich after he had all the members of the High Lords of Terra assassinated.
 * Age of Apostasy (378.M36) - At the height of the Age of Apostasy, an elite Space Marine strike force composed of the Imperial Fists, Black Templars, Fire Hawks, Soul Drinkers, and the forces of the Adeptus Mechanicus assaulted the renegade High Lord Goge Vandire's seat of power—the Ecclesiarchal Palace on Terra - effectively ending Vandire's "Reign of Blood" and his attempts to assume dictatorial control of the Imperium.
 * Haddrake Tor Campaign (ca. 800.M40) - The Imperial Fists take part in the three-year-long campaign to recover the world of Haddrake Tor from the clutches of Chaos. In the course of the campaign, 1st Company Captain Kleitus is mortally wounded, but passes on the Imperial Fists' relic, the Thunder Hammer known as the Fist of Dorn and the command of the 1st Company to Darnath Lysander before his untimely death.
 * Nimbosa Crusade (790.M41) - The Imperial Fists took part in the Nimbosa Crusade alongside one of their Successor Chapters, the Black Templars, reclaiming the Imperial world of Nimbosa from the encroaching Tau Empire.
 * Conquest of Uttu Prime (Unknown Date.M41) - Nemesor Zahndrekh's ultimatum had given the Imperial defenders of Uttu Prime one solar month to withdraw, as was required by the ancient Necron codes of battle. Yet, when the deadline had passed, the foolish humans had not availed themselves of this most generous of offers. Indeed, whilst the Necron fleet held in intentional abeyance in orbit around Uttu Prime's desert moon, four regiments of the Imperial Guard's Catachan Jungle Fighters and three companies of Imperial Fists Space Marines had come to reinforce the contested world. So it was that when Zahndrekh finally launched his assault, he did so against a planet with formidable defences. However, when his courtiers argued against prosecuting the war to completion, the Nemesor merely issued a grating laugh and sent the interstitial command that set his fleet in motion. Zahndrekh initially ignored Uttu Prime's outlying cities, focussing his assault on Fort Anan, the planetary capital. Zahndrekh's first attack wave was a dozen squadrons of Doom Scythe fighter craft. They swarmed over Fort Anan's fortifications, death rays raising great furrows of twisted metal and stone as they ploughed through bastions, ferrocrete walls and the luckless human defenders therein. To their credit, the humans put up a spirited resistance. Hydra Flak Tanks and Defence Lasers scoured the skies, driving off or blasting apart many of the swarming Necron aircraft. Yet each time a Doom Scythe was destroyed, another immediately peeled off from the main group to exact vengeance. Soon, Fort Anan was stripped of aerial defences, and the landings began. Transport craft followed in the wake of the first attack wave. Night Scythes flew low over the wreckage of crashed Necron flyers and Imperial bastions. Small arms fire scattered across the Night Scythes' armoured hulls as their flickering teleportation invasion beams delivered Zahndrekh's assault troops into the heart of the humans' defences. Phalanx upon phalanx of Immortals and Necron Warriors stalked through the fresh ruins, Gauss Weapons blazing in unnaturally precise volleys as they drove the Catachans back. Here and there, an officer's barked orders held the Guardsmen in line, but where those commanders fell, the Imperial lines went into full retreat. It was as the attackers' lines reached the Planetary Governor's citadel that the Imperial Fists finally made their presence known. Thunderhawk gunships screamed through the skies, shredding the oncoming Necron Warriors with Heavy Bolter fire and blasting Immortals limb from limb with missile strikes. As the gunships touched down amongst the rubble to disgorge Space Marines into the fray, the Necrons shifted to defensive protocols and awaited reinforcements. Alas for the Imperial Fists; from his vantage point in orbit, Zahndrekh had marked the approach of the Thunderhawks long before they had made their presence known planetside. Thus, even as the roar of Bolter-fire echoed through Fort Anan's ruins, a shadow fell over the battlefield as the massive Necron Megalith descended. The Megalith was no ordinary war engine, but a vast floating fortress. Green fire lanced out from its flanks, blasting Thunderhawks from the air or crippling them on the ground. As the shadow grew larger, chunks of the Megalith's understructure broke away, the blocks falling lazily to the ground. They were no mere wreckage, but Monoliths detaching from the mothership's hull. As each touched down, it added firepower to the barrage assailing the Imperial Fists. The Space Marines must have determined that they were doomed, but duty and stubborn tenacity made them redouble their efforts. Lascannon and Multi-melta fire flickered through the ruins, the beams converging to pierce the Monoliths' necrodermis hulls. Assault Squads threw themselves at the Necron phalanxes, Chainsword teeth screaming as they ripped through living metal bodies. However, the Megalith was now close enough to the ground to bring its invasion beams into play. Ghoulish viridian light flickered over the battlefield as the teleport beams activated, delivering Doomsday Arks, legions of Necron Immortals, as well as Zahndrekh and his personal Lychguard, into the thick of battle. Those Space Marines that yet survived now withdrew to the Planetary Governor's citadel, but three Doomsday Arks converged their fire on the great adamantium gate. For a handful of moments it glowed an angry red, then burst into fragments with an ear-splitting crack. As the Imperial Fists fell back deeper into the citadel, Zahndrekh raised his Warscythe in salute to the doomed foe. Then the scythe swept down and the Nemesor led his triumphant army of the undying through the ruined gate. Shortly thereafter, Fort Anam had fallen. The rest of Uttu Prime would soon follow, and another world would be added to the territory of Gidrim -- and the growing personal domain of Nemesor Zahndrekh.
 * Scouring of Malodrax (966.M41) - The 1st Company's Captain Darnath Lysander leads the Imperial Fists to the Chaotic fortress-world of Malodrax and successfully scours their ages-old enemies, the traitorous Iron Warriors, from the planet.
 * Khai-Zhan Uprising (968.M41) - The Imperial Fists 5th and 9th Companies are deployed alongside four Cadian Imperial Guard Regiments to the world of Khai-Zhan to suppress the heretical Khai-Zhan Uprising against Imperial authority. The Imperial Fists force is instrumental in countering the warband of Night Lords Chaos Space Marines taking part in the uprising, laying siege to the heavily fortified citadel called the Palace of Peace.
 * Defence of Miral (ca. 997.M41) - 1st Company Captain Lysander and his battle group intercepts the Tyranid Hive Fleet Leviathan in the Miral System on the planet of Miral where defensive fortifications are established. Despite being severely outnumbered, the battle group drives off the incipient Tyranid swarm on the seventh day, one day after the defense was expected to fail.
 * 13th Black Crusade (999.M41) - The Imperial Fists arrived at the Cadian Gate as part of the massive Adeptus Astartes reinforcement of the region, five companies smashing into the forces of the Archenemy at Cadia as soon as contact was made. After an initial void engagement that saw the Chapter's Battle Barges and Strike Cruisers take a fearsome toll on the Chaos warfleet besieging the Cadia System, three of the companies carried out a combat drop on Cadia itself, while the other two dispersed to bolster the defences in surrounding sectors, including reinforcing the Iron Hands Chapter at their homeworld of Medusa. The 1st, 2nd and elements of the 3rd Companies were instrumental in the defence of key points on Cadia, manning the walls of a number of fortresses with the steadfast resolution for which they are famed throughout the Imperium. In these actions, the 2nd Company was noted for exceptional acts of gallantry, overcoming a horde of mutants from the notorious Stigmatus Covenant Chaos Cult that numbered almost 10,000 traitorous fanatics. At the height of the assault on the walls of Kasr Vasan, the company commander, Captain Tialo, gave his life holding a breach in the fortifications, repelling a mob of mutants numbering several hundred before succumbing to the terrible wounds inflicted upon him. The Captain's body refused to die, however, and was held in stasis by the Chapter's Techmarines, who hoped to inter it within the mighty form of a Dreadnought so that the renowned warrior might continue to battle the forces of darkness beyond the death of his mortal body.

The Phalanx
The Imperial Fists are unique among the Space Marine Chapters because they have no fixed home planet and are officially based on Terra. This is because of their Terran origins, as well as their pre-Heresy role as the praetorian custodians of the Emperor, following Him wherever He went in their vast, 10,000-year-old mobile space fortress,the Phalanx. They have transformed the Phalanx into their primary fortress-monastery, although they also maintain recruitment fortress-chapels on various worlds throughout the Imperium. It is known that the Emperor had reached the ice hives of Inwit when Rogal Dorn showed himself to the Emperor aboard the Phalanx.

The Phalanx is the massive starship that serves as the mobile fortress-monastery of the Imperial Fists Space Marine Chapter and was constructed many millennia ago by unknown hands during the Dark Age of Technology long before the Age of the Imperium. Officially, the homeworld of the Imperial Fists is always listed as Terra, but in reality, the Phalanx serves as the Imperial Fists' true base of operations. Originally discovered adrift in space by the Imperial Fists' Primarch Rogal Dorn, the massive vessel was given as a gift to the Emperor of Mankind when Dorn was discovered near the Ice Hives of Inwit by his gene-father. The Emperor then returned the massive spacecraft to Dorn after he was appointed as the commander of the Imperial Fists Space Marine Legion. Phalanx itself is gigantic, the largest starship known to have been constructed by human hands, and something of its magnitude has not been seen since the Dark Age of Technology. The size of a small moon or large asteroid, its foredeck can dock a dozen Imperial Navy Cruisers around its circumference. The vessel is essentially a hive city in space, with its great spires reaching towards the stars, giving it the appearance of a giant mace-head. In many ways, Phalanx is the only vessel ever built by Mankind that comes close in size and complexity to that of the Eldar's Craftworlds. Phalanx is so large that it reflects light like the stars themselves, and it served as a symbolic representation of the Emperor Himself during the time of the Great Crusade. The vast starship is completely mobile and capable of travel through the Warp and often follows the Imperial Fists Chapter as it moves throughout the galaxy.

Chapter Organisation
Initially, the Imperial Fists were an inflexible formation; each company had an identical organisation and company captains tended to be unimaginative. Overall strategic planning for the Legion was excellent, however, and this, coupled with the unshakable determination of the individual Imperial Fists, made them an excellent assault formation against static defences. Through most of the Great Crusade, the Imperial Fists would be held in reserve, waiting while other Legions pinned the enemy in position and identified the keystone of their defence. Inevitably, that position would then be shattered by the Fists. They were equally valuable when resolutely blocking, and often totally defeated enemy counteroffensive breakthroughs. The Legion had a willingness to fight until they earned victory, which few opponents could match. Rogal Dorn led from the front, a tireless warrior who, having set the strategy for a battle, would unerringly place himself in the front ranks of most critical engagements.

After the losses incurred in the Iron Cage, what remained of the Imperial Fists was a hardened, veteran force fully able to embrace the concepts of the Codex Astartes; alongside the Ultramarines, the Imperial Fists have become the epitome of Codex doctrine. All ranks are able to make tactical decisions and are encouraged to act on their own initiative. The Imperial Fists combine all arms in flexible balanced battle groups each of which can present an opponent with a diversity of threats, then press their attack so swiftly that the foe is overwhelmed before he can react. The Imperial Fists since the Heresy have retained their traditional skills in urban and siege warfare, although they are quite willing to engage and defeat the enemy in open battle in any environment. They will use fortifications on the defensive, but only after all of the more aggressive options have been exhausted. The Fists' only weakness is perhaps a reluctance to accept the possibility of defeat. This sometimes blinds them to the risks inherent in their aggressive stratagems.

Like all Codex Astartes-compliant Space Marines Chapters, the Imperial Fists are divided into 10 companies comprised of 100 Space Marines each. Each company is led by a hero of the Chapter with the rank of Captain, who - in addition to his company command - is in charge of a particular aspect of the Chapter's logistics.

Imperial Fists Librarians
Like their fellow Astartes Chapters, the Imperial Fists also maintain a Librarium of potent psykers who are highly talented and trained to master the power of the Warp at the highest levels. Each Chapter selects its Librarians in its own way, either from seed worlds, as it does with the bulk of its Initiates, or from the ranks of gifted psykers brought to the Scholastica Psykana. Most Chapters train and test their chosen psykers following the ancient ways laid out in the Codex Astartes. Librarians of the Imperial Fists are trained in this way with few minor traditional variances, and have been taught to live by the word of the Codex. Imperial Fists Librarians have a number of unique psychic abilities only used by the psykers of their Chapter:
 * Into the Crucible - The Librarian calls upon the spirits of all those Imperial Fists who gave their lives at their Primarch's side during the battle of the Iron Cage. The blows of his enemies are turned aside or healed by the incarnate force of his ancestors.
 * Noble Praetorian - Rogal Dorn is remembered by many as the right hand of the Emperor, His most faithful son who stood watch over Him and enacted his every command with unshakable loyalty. Reaching into his soul and his genetic inheritance, the Librarian channels a portion of Dorn's noble spirit, making himself a champion of the weak and a defender of the just, greatly enhancing his physical abilities and morale in combat.
 * Stonebane - No wall or fortification can stand against the will of Dorn made manifest. The Librarian channels his powers into an attack so terrible that no stone will be left standing upon another. The ground quakes, the skies darken and the air itself screams as a mighty etheric hammer manifests itself in the Librarian's grip. Stonebane may be used when the Librarian is faced with a wall, fortification, bunker or similar structure that he wishes to smash asunder.
 * The Golden Son - The Librarian is transformed into a radiant figure suffused with the power and nobility of his Primarch. Friends witness a glorious sight not seen since Rogal Dorn himself walked amongst Men, while enemies see the fiery harbinger of their doom.
 * Ultimate Sacrifice - The Imperial Fists are possessed of the most selfless spirit of any Chapter, willing to lay down their very lives for causes others would abandon as hopeless. The Librarian channels this spirit into himself, causing fate to deliver blows meant for his fellows to strike him instead.
 * Wave of Penance - The Librarian reaches into the ether and draws forth all of the pain suffered by his ancestors in the self-imposed atonement of the Pain Glove and a hundred other such rituals. In an instant, ten thousand standard years of penance is unleashed upon his foes, and every iota of pain ever felt by the Chapter is turned back upon its foes in an unstoppable blast wave.

Chapter Recruitment
Being a space-borne Chapter, the Imperial Fists recruit from a variety of worlds, including Terra and Necromunda. The Chapter maintains a great number of Fortress-Chapels on planets across the Imperium. Such places are staffed by small, dedicated cadres of Veterans, perhaps Imperial Fists warriors wounded so grievously they can no longer fight, but are still well able to serve their Chapter. However, the Imperial Fists have no special political rights on the worlds where they recruit their Neophytes as other Chapters do. The staff of these facilities keep a watch upon the peoples around them, seeking potential candidates for recruitment. On some worlds they hold tournaments and contests to ascertain suitability, while on others they actually instigate combat in order to test potential recruits in person. On some Hive Worlds, the Imperial Fists conduct purges of the down-hive slums, ostensibly to clear out undesirable elements on behalf of the planetary government, but they often return with captives they have judged such worthy fighters they will be invited to undertake the trials to become a Neophyte of the Chapter.

The Imperial Fists are unusual in making few, if any, demands of the peoples of the worlds they recruit from, other than the right to test those who believe themselves worthy of entering the ranks of the Battle-Brothers. Whatever the source of the recruit, whether he comes from a brotherhood of warrior-knights or a band of hive-gang psychopaths, the Chapter instils its noble doctrines in him, retaining his essential martial qualities but overlaying them with the qualities that the Imperial Fists have inherited from their Primarch and their ancestors. The Chapter is not especially shaped by the mores and character of the worlds its warriors are drawn form, and instead draws heavily on its own traditions and the values instilled in it by its Primarch.

Once Imperial Fists Aspirants are selected, their criminal record is examined, and they undergo a battery of tests determined to measure their musculature, psychological profile ("psychosis level"), psychic level, eye reflexes, intelligence, the ability to shoot, pain resistance, and dexterity. Recruits spend six months in the Phalanx where they learn proper Imperial Low Gothic through the use of a hypnocasque before undergoing their initiation in the "tunnel of terror." In the latter, they face extreme heat, cold, empty space, etc. The severity of the trial increases along the way. If the Aspirant passes, he becomes a Neophyte cadet and the symbol of the Imperial Fists is tattooed on his buttock. Then begins the psycho-indoctrination, training and the actual surgery and implantation of the gene-seed organs that will make the Neophytes into true Astartes. To celebrate the introduction of the Preomnor implant, cadets eat poisonous plants, venomous animals, etc. For the Omophagea, they consume meat and must divine from the meat a few details about the nature of the actual animal. After the initiation ceremony, the Neophyte's family is informed that their child has become a Space Marine in service to the Emperor so that they may rejoice at their offspring's great fortune.

Deathwatch Service
The Imperial Fists as a Chapter might have largely withdrawn from the Jericho Reach, but they are well represented in the ranks of the Deathwatch. The Sons of Dorn are known to have contributed Battle-Brothers to the Deathwatch since its earliest days, and given the Chapter’s reputation and character it is hardly surprising that this should be so. Many of those standing their Vigil at Watch Station Erioch took the Apocryphon Oath as their Chapter began redeploying to other warzones, choosing to remain and complete the obligations that had brought the Imperial Fists to the region in the first instance.

One such individual is Chaplain Magno Stoan, who served as a Chaplain to the Imperial Fists' 3rd Company for the best part of two standard centuries before the deployment of five of its squads to the Jericho Reach in 801.M41. Chaplain Stoan was present at numerous great victories, including the fall of Fort Crimson, the breaching of the 48th Parallel, and was instrumental in the destruction of the Space Hulk Scion of Vehemence. It was during a mission into the Slinnar Drift that Chaplain Stoan encountered a new and deadly foe—the Dark Eldar. Despite the ferocity of the Imperial Fists’ defence, they found themselves surrounded and impossibly far from any hope of reinforcement. The details of the battle are known only to Chaplain Stoan himself, for no others survive to describe it. Stoan has vowed to keep his own counsel on the matter, but it is known that he was taken alive, having been struck by dozens upon dozens of toxic projectiles, his superhuman constitution finally overcome by the xenos poisons. Dragged back to the Dark Eldar’s fell demesnes, Stoan was tortured and prepared to fight in the gladiatorial arenas of a Wych Cult for the entertainment of the bloodthirsty masses. Though he has never recounted how, Chaplain Stoan not only resisted the tortures his captives inflicted upon his flesh, wounds he still bears the scars of to this day, but he broke his bonds and escaped, capturing one of his tormentors in the process. At length, Stoan made it back to the Jericho Reach, his captive in tow.

Making straight for Watch Station Erioch, Chaplain Stoan presented his prize to the Deathwatch and declared that he would take the Apocryphon Oath. This he did, and while the captive withered and died within a matter of weeks, Stoan and the Deathwatch learned much from the sadistic Dark Eldar before it met its end. The Chaplain stands his Vigil to this day, ministering to the spiritual needs of his Battle-Brothers, regardless of which Chapter they hail from. It is also said that he harbours a special hatred for the Dark Eldar, and that he has tutored numerous brethren in the mental and spiritual disciplines required to resist their torments. This is perhaps Chaplain Stoan and the Imperial Fists’ greatest legacy to the Deathwatch, for thanks to the suffering of one man, all are ultimately made stronger.

Chapter Gene-Seed
The Imperial Fists' gene-seed is very stable and has never exhibited signs of mutation. However, over time they have lost the use of two of the special organs produced by the basic Astartes genetic template: the Betcher's Gland, which allows a Space Marine to produce poisonous/acidic spittle, and the Sus-an Membrane, which allows an Astartes to enter a state of suspended animation.

Another peculiar and unexplained quirk of the Chapter is the Imperial Fists' pathological need to scrimshaw the bones of their dead when off-duty. Scrimshaw is considered a solemn undertaking to the Astartes of this Chapter. It is seen as a way to practice mental discipline, focus, and attention to detail. Oftentimes the finished scrimshaws are worn as jewelry and ornamentation, particularly by the Chapter's officers. None know the roots of this practice, which for many Imperial Fists becomes an obsession they must indulge every hour they are not fighting or training. The bones of slain kin are engraved in minute detail, every surface lovingly covered in lines of devotional script and illuminated scenes depicting the deeds of the fallen. Even the bones of the Chapter's Primarch have been engraved in this manner, preserved as the most sacred relic the Chapter possesses.

The only worrying trait that has attracted scrutiny is the Imperial Fists' over-zealous self-castigation. They often make use of a device called the "Pain Glove", which encases the whole body and stimulates its pain neurons. The Imperial Fists constantly feel the need to punish themselves for the smallest inadequacy, failure or infraction. The last remaining relic of Rogal Dorn, his skeletal hand, is displayed in their fortress-monastery on the Phalanx as a reminder of the ultimate dedication to their duty and the Emperor required of the Space Marines. Considering the circumstances of Rogal Dorn's eventual death, it is clear that the Imperial Fists have a drive for self-sacrifice that they must continually battle to overcome.

Although the Imperial Fists have a preference for long-range engagement and specialise in siege warfare, they are also well-known for their passion for dueling, a tradition thought to date back to the earliest days of the old Legion, before it even left Terra on the Great Crusade. The Imperial Fists engage in ceaseless duels against one another, sometimes to settle a point of honour but more often to test themselves and their swordsmanship. The most experienced and long-serving Imperial Fists sport numerous duelling scars all over their bodies, each a reminder of a hard-won victory, or a salutary defeat.

Notable Imperial Fists

 * Rogal Dorn - Rogal Dorn was the Primarch of the Imperial Fists Legion and one of the greatest heroes in the history of the Imperium of Man. Dorn constructed the defences of the Imperial Palace in the Himalayan Mountains on Terra that would be sorely tested by the Forces of Chaos during the climax of the Horus Heresy, the terrible Battle of Terra. He is presumed to be deceased after leading an assault against a Chaotic flagship during the 1st Black Crusade. His supposed remains are now sacred relics of the Chapter kept aboard their mighty Chaptership Phalanx.
 * Chapter Master Vladimir Pugh - Pugh is the current Chapter Master of the Imperial Fists. Whilst not a particularly inspirational leader, Pugh is considered as meticulous a planner as any Chapter Master in the Imperial Fists' history.
 * Chapter Master Lazerian - Chapter Master of the Imperial Fists during the Age of Apostasy in the 36th Millennium and present during the Second Siege of the Imperial Palace where the Black Templars, Imperial Fists, Soul Drinkers and Fire Hawks fought to depose the insane High Lord Goge Vandire.
 * Chapter Master Bronwin Abermort - One of the Imperial Fists' early Chapter Masters.
 * Chapter Master Maximus Thane - One of the Imperial Fists' early Chapter Masters.
 * Chapter Master Kalman Flodensbog - One of the Imperial Fists' early Chapter Masters.
 * Chapter Master Ambrosian Spactor - One of the Imperial Fists' early Chapter Masters.
 * First Captain Sigismund - During the Horus Heresy era, Sigismund was the First Captain of the Imperial Fists. Due to his fighting prowess, Sigismund was singled out by Rogal Dorn and was given the best arms and equipment, becoming the first Emperor's Champion for the Legion. During the Second Founding, Sigismund would go on to lead the more zealous elements of the Imperial Fists and was elevated to the esteemed rank of High Marshal (Chapter Master) of the newly formed Black Templars Chapter.
 * Captain Camba-Diaz - During the Horus Heresy era, Camba-Diaz was the Second Captain of the Imperial Fists Legion. Due to his fighting prowess and ability to stay cool under fire, Primarch Dorn often deployed Captain Camba-Diaz beside First Captain Sigismund. The resolute and taciturn Captain was a soothing balm to Sigismund's fiery temper. They complemented one another in battle. During the Horus Heresy Camba-Diaz played an instrumental role in the vital mission to obtain armour and munitions from the forges on Mars during the great civil war known as the Schism of Mars which had erupted between the Loyalist Mechanicum and Dark Mechanicus forces.
 * Captain Efried - Efried was the Third Captain of the Imperial Fists Legion during the Horus Heresy. Captain Efried served as adjutant to Rogal Dorn during the fortification of the Emperor's Imperial Palace. Captain Efried had previously served alongside the Luna Wolves' 3rd Company in the Great Crusade during a year-long Imperial Compliance campaign. With the outbreak of the Horus Heresy, Captains Efried and Halbrecht served alongside Primiarch Dorn during the early days of the fortification of the Imperial Palace and the preparation of Terra and the entire Sol System for the invasion of the Traitor Legions of Horus.
 * Captain Alexis Pollux - Alexis Pollux was described as a giant of a man whose physical strength belied a cold, rational and supremely logical mind. His character traits displayed the legacy of his Primarch Rogal Dorn. During the Second Founding when the Imperial Fists Legion was broken down into Chapters, Pollux became the first Chapter Master of the newly created Crimson Fists Space Marine Chapter.
 * Captain Aleph - Aleph was the Captain of the Imperial Fists who was present during the defence of the Emperor's Imperial Palace on Terra at the climax of the Horus Heresy. He was the ancestral source of the gene-seed used in the transformation of Captain Demetros in the 41st Millennium, and was eventually slain by the Black Legion Captain Scaevolla, a former comrade-in-arms of Aleph. Scaevolla allowed Aleph's Progenoid Glands to be recovered by the Imperial Fists, however, so that another would inherit Aleph's genetic legacy. The Black Legion Captain would then one day face this new recipient of Aleph's genetic legacy, thus starting the cycle of confrontation and death all over again.
 * Captain Halbrecht - Halbrecht was a Captain of the Imperial Fists Legion who served during the Horus Heresy. Along with Captain Efried, Halbrecht was the only other captain of his Legion to accompany Rogal Dorn to Terra with former Death Guard Battle-Captain Nathaniel Garro and his heroic 70 Astartes survivors of the virus-bombing of Istvaan III. The rest of the Legion went to investigate Istvaan before returning to Terra. In the meantime, Halbrecht and Efried served Dorn during the early days of the fortification of the Imperial Palace and the preparation of Terra and the entire Sol System for the invasion of the Traitor Legions of Horus.
 * Captain Learchus - Learchus was an Imperial Fists Captain who served with the Legion during the Great Crusade and Horus Heresy eras. He was present at the defence of the Emperor's Imperial Palace during the Battle of Terra, and was killed fighting against Death Guard Plague Marines.
 * Captain of the Banner Navarre - Navarre was the Emperor's Champion of the Black Templars Chapter who carried the Chapter Banner across the breach in the walls of the Imperial Palace during the height of the fighting during the Second Siege of the Imperial Palace in the 36th Millennium. For his actions, he was granted the honorary title "Captain of the Banner" within the Imperial Fists Chapter by the Imperial Fists' Chapter Master Lazerian.
 * Captain Darnath Lysander - Darnath Lysander is the Captain of the 1st Company, Overseer of the Armoury and Watch Commander of the Phalanx. The famous Imperial Fist Captain first appeared in the Liber Honorus Imperial Fists in 567.M40 as a Sergeant in command of a unit of the 2nd Company where he was victorious over a group of Heretics on Iduno at the Battle of Colonial Bridge. He was then promoted to command of the 2nd Company in 585.M40 after successfully boarding and capturing an Eldar Cruiser. During the three year siege of the world of Haddrake Tor to retake it from the Forces of Chaos, Lysander witnessed the death of the Captain of the 1st Company, Kleitus, and from him received the Imperial Fists' sacred relic Thunder Hammer, the Fist of Dorn, which he used to go on and conquer the Heretics. Lysander was soon after promoted to command the elite 1st Company, which he led for many years. Whilst leading a force of Imperial Fists, they disappeared into a Warp Storm and were feared lost, though the Chapter patiently waited for his return for quite some time. The Chapter ultimately pronounced Lysander and his men dead in absentia. In truth, Lysander's starship re-emerged into Chaos-held space where it was captured by the Imperial Fists' bitter enemies, the Iron Warriors. Lysander and the survivors were captured and taken by the Traitors to one of their accursed Fortress Worlds, known as Malodrax, and were tortured for years. Eventually Lysander, without weapons or armour, effected his escape and fought his way off the accursed Chaos world to freedom. When he returned to the Imperial Fists Chapter, many centuries had passed in the material universe. Fearing that he might have been tainted by the Ruinous Powers, Lysander was thoroughly screened by the Chapter's various specialists and found free of Chaotic taint. Afterwards, Captain Lysander was reinstated to his position as Captain of the 1st Company. Lysander then lead a force to raze the Iron Warriors from Malodrax and laid the world to waste, achieving his vengeance at last.
 * Captain Taelos - Taelos was the Captain of the 10th Company, and the former Captain of the 2nd Company. Whilst in command of the 2nd Company, Captain Taelos played a vital role against the Tau's expansion during the Nimbosa Crusade. The contested planet of Nimbosa on the outskirts of the Tau Empire had been fought over several times before and the Imperial forces there were stretched to the brink of collapse. Captain Taelos and Imperial Ambassador Palmatus traveled to the Tau world of T'olku in an attempt to stall the Tau invasion. They were unsuccessful, but with the arrival of the Black Templars, Ultramarines, Raven Guard and several other Astartes Chapters, the tide quickly turned and the Tau were driven from the world without mercy. The Black Templars established a Chapter keep on the world. Elements from the 2nd Company were present during the Koloth Gorge Massacre, where Commander Brightsword of the Tau Empire ambushed and slaughtered an entire regiment of Imperial Guard and many of the Imperial Fists present. Captain Taelos himself was severely wounded and following the massacre, Taelos was incapacitated for the rest of the campaign and another took his place to command the 2nd Company. After the campaign, Captain Taelos sought leave to go on a Warrior Pilgrimage, a lone trip across the Imperium to fight the enemies of the Emperor alone until death claimed him, to atone for the loss of so many Space Marines under his command, but Chapter Master Pugh refused and instead appointed Taelos to command of the 10th Company. It was Captain Taelos himself who recruited s'Tonan, du'Queste and Zatori and watched them rise through training and their trial as Scout Marines to become full Battle-Brothers.
 * Captain Alaric Eshara - Eshara is the Captain of the Imperial Fists' 3rd Company. Eshara led his company against the Iron Warriors on the planet of Hydra Cordatus. Unbeknownst to the defenders, the world of Hydra Cordatus was one of two large storage facilities for their tithes of Space Marine gene-seed possessed by the Adeptus Mechanicus. The genetic material at these centres was used to test all active Chapters for genetic purity and to create new Chapters during a Founding. While the defenders fought with faith and skill they were ultimately defeated in the end, and most of the gene-seed was captured by the Traitors. The Imperial Fists fought to the last and Eshara himself was cut down by the ascendant Iron Warriors Warsmith who became a powerful Daemon Prince of Chaos following this victory.
 * Lexandro D'Arquebus - Former Captain of the Imperial Fists. A high-habitat resident of the Trazior Hive on Necromunda before his recruitment into the Imperial Fists, Lexandro rose rapidly through the ranks of the Imperial Fists. He is the only surviving one of the "Three Brothers" of Trazior; the finger bones of his left hand are inscribed with the names of his two deceased Battle-Brothers from the hive city of Trazior as a permanent memorial to them. He is one of the main characters of Ian Watson's recently re-released non-canon 1993 novel Space Marine, and also appears in his Inquisition War trilogy.
 * Deathwatch Captain Bannon - Captain Bannon was the Imperial Fists Astartes who served as the leader of the Deathwatch Kill-team present during the defence of the world of Tarsis Ultra, tasked with assisting Inquisitor Kryptman in fighting the Tyranids. Bannon and his team aided the defences alongside the Space Marines of the Mortifactors and Ultramarines Chapters, though Bannon himself and half of his team died during the course of the events on Tarsis Ultra. Their death was not in vain, however, as the Tyranids were eventually fought off after the death of one of their Norn-Queens.
 * Deathwatch Captain Octavius - Captain Octavius was the Imperial Fists Astartes who led a Deathwatch Kill-team that included three individuals seconded temporarily from the Mantis Warriors Space Marine Chapter. These Astartes, previously disgraced due to their actions during the Badab War, proved their honour with the Deathwatch following a series of heroic actions and sacrifices. After his actions on Herodian IV, Captain Octavius was given the rare honour of remaining seconded by his Chapter to the Deathwatch permanently. However, his tenure was cut short when he fell in battle against a Dark Eldar Talos Pain Engine. One shoulder plate from his armour was all that was recovered by his team, though their mission was accomplished and no other members fell in battle. The team managed to escape their Dark Eldar captors and reach their grounded Thunderhawk gunship.
 * Archamus - Never so volatile as First Captain Sigismund, Archamus was the master of Rogal Dorn's Honour Guard retinue known as the Huscarls during the Great Crusade and Horus Heresy eras.
 * Instructional Officer Rhetoricus - A legendary figure within the Imperial Fists Chapter, Rhetoricus was a contemporary of Chapter Master Vladimir Pugh and the author of The Book of Five Spheres. In his later years, after his injuries placed him in a hover chair and rendered him unable to serve in the field, Rhetoricus was involved in instruction of Imperial Fists Neophytes during training and implantation of their gene-seed.
 * Lo Chang - Lo Chang was a moon-faced Chaplain of the Imperial Fists and served as the Chapter's Master of Sanctity and Reclusiarch. He has a countenance that is badly scarred by crater-like wounds incurred when his helmet failed him in combat. When Lo Chang preaches, he is swept up in devout ecstasy wherein his passion can inspire any Imperial Fists Space Marine to strive to be a true child of Rogal Dorn and servant of the Emperor of Mankind. Lo Chang appeared in the recently re-released non-canon novel Space Marine by Ian Watson.
 * Carnark - Chaplain Carnak was the Keeper of the Shrine of Mithron for centuries, having served the Chapter for more than four hundred standard years. Chaplain Carnak and his assistant Brother Nidon were the only survivors of the Shrine Guard stationed on the planet, as the rest of the Imperial Fists' 5th Company was wiped out by a force of Chaos Space Marines. Chaplain Carnak was killed by the possessed body of Ultramarines Captain Severus aboard the 2nd Company's Strike Cruiser in orbit over Mithron, the daemon within Severus executing Carnak before he could reveal Severus' possession to the other Space Marines present.
 * Dominicus - Chaplain Dominicus was attached to the Imperial Fists' 10th Company during its recent recruiting mission aboard the Strike Cruiser Capulus. Dominicus is a stern but inspiring man, charged with first introducing Initiates to the Chapter to the Pain Glove, and instructing them in the Imperial Fists' Cult of Dorn.
 * Magno Stoan - Magno Stoan served as a Chaplain to the Imperial Fists' 3rd Company for the best part of two standard centuries before the deployment of five of its squads to the Jericho Reach in 801.M41. Chaplain Stoan was present at numerous great victories, including the fall of Fort Crimson, the breaching of the 48th Parallel, and was instrumental in the destruction of the Space Hulk Scion of Vehemence. It was during a mission into the Slinnar Drift that Chaplain Stoan encountered a new and deadly foe—the Dark Eldar. Despite the ferocity of the Imperial Fists’ defence, they found themselves surrounded and impossibly far from any hope of reinforcement. The details of the battle are known only to Chaplain Stoan himself, for no others survive to describe it. Stoan has vowed to keep his own counsel on the matter, but it is known that he was taken alive, having been struck by dozens upon dozens of toxic projectiles, his superhuman constitution finally overcome by the xenos poisons. Dragged back to the Dark Eldar’s fell demesnes, Stoan was tortured and prepared to fight in the gladiatorial arenas of a Wych Cult for the entertainment of the bloodthirsty masses. Though he has never recounted how, Chaplain Stoan not only resisted the tortures his captives inflicted upon his flesh, wounds he still bears the scars of to this day, but he broke his bonds and escaped, capturing one of his tormentors in the process. At length, Stoan made it back to the Jericho Reach, his captive in tow. Making straight for Watch Station Erioch, Chaplain Stoan presented his prize to the Deathwatch and declared that he would take the Apocryphon Oath. This he did, and while the captive withered and died within a matter of weeks, Stoan and the Deathwatch learned much from the sadistic Dark Eldar before it met its end. The Chaplain stands his Vigil to this day, ministering to the spiritual needs of his Battle-Brothers, regardless of which Chapter they hail from. It is also said that he harbours a special hatred for the Dark Eldar, and that he has tutored numerous brethren in the mental and spiritual disciplines required to resist their torments.
 * Akrida - Akrida is a Chaplain of the Imperial Fists who served during the Great Crusade and Horus Heresy eras. He was present at the defence of the Imperial Palace during the Battle of Terra.
 * Borgos - Borgos is a Chapter Librarian who holds the rank of Epistolary. He was attached to the 10th Company during its recent recruiting mission aboard the Strike Cruiser Capulus. Though Borgos is physically blind, he refuses [[augmetic implants. This is because his blindness does not hinder him in the slightest as his Warp sight is far superior to whatever mortal sight might provide him.
 * Corwin - Corwin was a Librarian attatched to the Imperial Fists 3rd Company under Captain Eshara during the relief of beleaguered Imperial forces on the world of Hydra Cordatus which was under siege by a large warband of Iron Warriors Chaos Space Marines. Corwin sacrificed himself to open a portal through the Warp to allow a horrific Greater Daemon of Khorne to leave the fighting on Hydra Cordatus and hopefully spare his comrades from death at its hands. Where the daemon went or the result of this action on Corwin's soul are unknown, but his valiant sacrifice did buy the Imperial defenders some time, though in the end the battle was still lost.
 * Franz Grenstein - The Imperial Fists Librarian Franz Grenstein is described as dusky-skinned, with criss-crossed duelling scars on both cheeks from numerous honour duels. An intense and preoccupied Imperial Fists Librarian, Grenstein takes his responsibilities to keep the Imperial Fists safe from psychic or daemonic enemies very seriously. On the rare occasions an Imperial Fists Space Marine is in contact with Chaos, it is Grenstein who will be assigned to help them regain their mental stability and ensure they have not brought Chaos's taint with them. Grenzstein was killed during a search-and-destroy mission against Tyranids; he appeared in the recently re-released non-canonical novel Space Marine by Ian Watson.
 * Lysol Blane - In 812.M39, Techmarine Blane wrote the Liber Proditor Armorum, a text containing his insight into the use of armoured units by the Traitor Legions. The Liber was set to be an approved addition to the sacred Codex Astartes when its inclusion was blocked for unknown reasons by the Iron Hands Space Marine Chapter.
 * Brother Szobczak - Szobczak is an ancient and cantankerous Deathwatch Dreadnought formerly of the Imperial Fists 5th Company. Inducted into the Chapter in the late 34th Millennium, he served with distinction. Eventually he became a Techmarine and was attached to the 5th Company, distinguishing himself as both a gifted siege engineer and tech-priest. For nearly two centuries he served the 5th Company. In early M35, Brother Szobczak was seconded to the Deathwatch at a long-lost Watch Station in the galactic East of Ultima Segmentum. At the end of his vigil, he petitioned to be allowed another, feeling that his work was far from complete. He was granted his request and completed three more vigils, acting as an infiltrator and sapper, until he was grievously wounded in a campaign supporting the Imperial Guard against an Ork Waaagh! His wisdom and unique skill-set were deemed to valuable to waste, and so, the Deathwatch honoured him by interring him within the Adamantium sarcophagus of a Dreadnought. Though he can remember his early days with the Imperial Fists and his first Vigils with the Deathwatch, he remembers little to nothing about his time as a Dreadnought. Records at Watch Fortress Erioch mention no Imperial Fists matching his name or description, nor is he listed amongst the Battle-Brothers slumbering in the Watch Fortress’s Chamber of Elders where the few Dreadnoughts officially attached to the Deathwatch are kept.
 * Scout Sergeant Zed Juron - Juron was the first Astartes squad leader to have Tundrish, d'Arquebus and Valance under his command. Juron led the Scout Marines during the Karkasson Campaign where the squad, code-named the "Wolverines," performed spectacularly. He orchestrated the capture and control of an Imperator-class Titan on that rebel-held world and took the throne of the Princeps during the battle. Later, he led a squad of Battle-Brothers under the command of Lieutenant Vonreuter in one of the Imperium's first boarding actions against a Tyranid Hive Fleet.

Chapter Relics
"If you bear the honour and glories of the past, you must also bear its duties."

- Danarth Lysander, Imperial Fists Captain


 * Armour of Dorn - Fragments of Dorn's golden Artificer Power Armour are kept by the Second Founding Black Templars Chapter.
 * Dorn's Skeletal Hand - The now skeletal hand of the Primarch Rogal Dorn recovered from the Chaotic warship known as the Sword of Sacrilege duing the 1st Black Crusade is one of the Imperial Fists' most sacred relics and is kept in stasis in the innermost chapels of the Phalanx. Each Chapter Master writes his name in minute script on the bones of the hand, a symbolic reminder of the Chapter Master's duty to the Primarch. When Rogal Dorn was still alive he and any new Chapter Master would slit their palms and clasp hands, the sacred blood of the Primarch mixing with that of the new Chapter Master. A symbolic and physical representation of the duty and responsibility of the new Master of the Chapter towards the Astartes of one of the Imperial Fists' Successor Chapters. With Dorn's death, the ceremony has ceased but by inscribing the names of its Chapter Masters on the bones of Dorn's hand the Chapter honours the memory of its bond with the Imperial Fists' progenitor.
 * Duty's End - Duty's End is a powerful relic Storm Shield. Brother Sergeant Artor and his squad were posted on the world of Deepcut IX, guarding a mine colony, when Ork raiders attacked. Despite assurances of assistance from the hundred or so miners, their chief foreman convinced them to flee and hide deep in the tunnels. The ten Space Marines were left to defend the mine head unaided against a horde of nearly a thousand Orks. The mine entrance was an excellent place to defend, but inevitably the Ork numbers overwhelmed the Imperial Fists. Artor was last to fall, countless Slugga shells impacting on his great Storm Shield as he hacked down Greenskin after Greenskin.
 * The Fist of Dorn - The Fist of Dorn is a legendary master-crafted Thunder Hammer traditionally wielded by the Captain of the Imperial Fists' 1st Company. The weapon is shaped to resemble a gauntleted fist that is holding each end of the warhammer's head. The arcane technologies built into the Fist of Dorn allows it to strike with far more powerful blows than that of a normal Thunder Hammer, and was designed to be most effective when used to assault heavily armoured vehicles and fortifications. It is currently carried into battle by Captain Darnath Lysander, who received it from his predecessor Kleitus when the latter was killed in a teleportation accident during the siege of Haddrake Tor.
 * Icon of the Iron Cage - Legend says that in memory of the Imperial Fists’ great battle against the Iron Warriors Traitor Legion and their rebirth as a Chapter, a handful of survivors of that time crafted Icons of the Iron Cage. No one knows if these stories are true. However, there are a few talismans used by the Imperial Fists in the Jericho Reach Deathwatch that bear a resemblance. Whether or not they are the very same Icons crafted millennia ago there is no way of telling, but their inspiring effects on the Battle-Brothers that wear them cannot be denied. Named for the infamous siege of the Imperial Fists against the Iron Warriors Traitor Legion, the Icon is a talisman worn on Power Armour that reminds the Battle-Brother of the strength of faith and unity his Chapter displayed against the Traitor Legions, and how that strength still flows through his Chapter today.
 * Ossific Relic - Many Imperial Fists bear small tokens of lost Battle-Brothers, engraving their bones with descriptions of their deeds so that they may never be forgotten and will live on forever. Ossific Relics take the form of small bones, normally finger or hand bones, carried in a small pouch near the Battle-Brother's heart, or sometimes on a chain around his neck or wrist. Far from grisly or barbaric, this practice is the ultimate act of remembrance for an Imperial Fist, and the relic of his fallen brethren are his most valued possessions.
 * Pain Glove - A tool of both torture and penitence, the Pain Glove is a cage of ancient technology and cunning design that the Imperial Fists have used for centuries to test their strength, punish the unworthy, and cleanse themselves of sins, weakness and guilt.
 * Roma - The Roma was the first Imperial battle honour won by the VII Legion at the start of the Great Crusade in the late 30th Millennium. The honour exists now only as a Ceramite icon, as it is too precious to be displayed in even the most heavily protected Inner Reclusium aboard the Phalanx.
 * Scrimshaw Tools - It is said that as an Imperial Fist grows older and sees more of his Battle-Brothers fall in combat, his urge to master the practice of scrimshawing the bones of his fallen kin becomes all but irresistible. Often, this devotional act serves to belay any sense of failure the Battle-Brother may feel for his own part in the death, whether real or imagined, and in some cases is an act of penance imposed by the Chapter Chaplains or by the Imperial Fist himself.
 * Soulspear - The Soulspear was an ancient Chapter relic wielded by the Primarch Rogal Dorn during the Great Crusade. It was forged from lost archeotech by the hand of the Emperor Himself, and gifted to His son. In battle it acted as a Warp vortex weapon, able to cut through anything. This sacred artefact was entrusted to the Imperial Fists' Successor Chapter, the Soul Drinkers, when the Legion was split during the Second Founding. The spear was lost for over ten thousand years before the Chapter discovered its whereabouts on an old derelict starfort. Upon destroying the starfort's defenders, the Soul Drinkers made their way to a treasure room in which the Soulspear was kept, where it was then stolen from their grasps by the Adeptus Mechanicus. In their obsessive need to obtain this sacred relic, the ensuing crisis resulted in a chain of events that saw the Soul Drinkers' declared Excommunicate Traitoris by the Inquisition. The Soul Drinkers eventually recovered the Soulspear, which was used by their Chapter Master Sarpedon to slay a Greater Daemon of Tzeentch named Abraxes.
 * Strikers of Allerox - These heavy gauntlets were worn by Captain Allerox in the purging of Hive Greyreach. The hive was infested by daemons who had slaughtered nearly half of the workforce populace. Allerox himself strangled the daemonic Herald of Khorne who had led the bloody rampage.
 * The Sword of Dorn - The blade carried by Rogal Dorn was shattered when Dorn broke it over his knee after returning from Horus' flagship Vengeful Spirit with the broken body of the Emperor at the end of the Battle of Terra. Dorn vowed never to wield the blade again as a penance for his failure to protect the Emperor. First Captain Sigismund kept the shattered blade and had part of it forged into the weapon known as the Sword of the High Marshals that is a relic of the Black Templars Chapter, as a reminder of the duty and sacrifice expected of the Sons of Dorn. The broken blade resides in the halls of the Eternal Crusader, the Battle Barge and flagship of the Black Templar Crusade Fleet.

Controversial Depiction
Ian Watson's novel Space Marine, the first fictional representation of the Space Marines ever written, revolves around the recruitment, training and combat experiences of an Imperial Fist Astartes. Unfortunately, the content of the book is no longer considered to be canon and in fact the tale has been deemed outright heretical by Imperial authorities.
