The **Iron Purity** are a Loyalist Successor Chapter created from the proud lineage of the Ultramarines, supposedly created as early as the 2nd Founding, following the bloody civil war of the Horus Heresy and the subsequent Great Scouring. An honourable and dedicated Chapter, the Iron Purity have continuously fought the enemies of Mankind for ten millennia, standing as a bulwark between realm of the Emperor and the encroaching darkness of the Ruinous Powers.

## Chapter History

### Origins

Founded after the Horus Heresy in 021.M31, they are a Chapter with troubled origins. Only a few members of the chapter's command staff know who their primogenitor is, although they are increasingly rare to hold this information. Their origins suggest that they are of Ultramarines' descent, although this has never been confirmed by any institution of the Imperium or the Iron Purity itself. They have been working in the region of the Segmentum Ultima for ten millennia, going where their talents are needed.
Their origins are sufficiently fuzzy to make each Chapter Master fear the impromptu visit of the Holy Inquisition. Since the almost total loss of their archives, they also lost all traces of their Primogenitor. Their traditions as well as their affinities with certain strategies, reinforce the fear of an unenlightened ancestry among the brothers.

## Notable Campaigns

* **War of the Beast (545.M32)**: It is known that the Chapter took a very active part in the defense of the borders of the Segmentum Ultima and Solar in the face of the assaulting moons of the Beast. The nature of the engagements was mainly spatial, given the strength of the Chapter fleet at that time. Several incursions were thus promptly annihilated at great cost by the Chapter's responsiveness in defending their Segmentum

* **Woe of the Iron Purity (923.M32)**: The Chapter came close to extinction and lost almost all of its Archives to an enemy of unknown nature. None of the Chapter's veterans survived, and the Iron Purity went into a long period of military inactivity to rebuild. It is likely that during this time, the Chapter holed up in an uncharted system and conducted recruitment raids in the surrounding systems, before heading to a familiar world such as Catorsha. It is also theorized that it was at this time that the Tarant Tertius station was claimed by the Chapter to defend the far bangs of its territory. It remains unclear how many years or centuries this forced settlement lasted, but it is possible that this time span could be counted in millennia.

* **Age of Apostasy - Crusade of Wrath (238.M36)**: There is no clear record of the Iron Purity's actions during the Age of Apostasy, but it would appear that their activities took a more radical turn. They claim that they spent most of their time pursuing and eradicating Astartes Chapters that had turned to the Powers of Ruin during this dark period. This "crusade" would have cost the Chapter a great deal of money, which explains the lack of documentation of this period according to them, but also the creation of the Red Rampart and the reinforcement of the Protocol to guard against corruption. It is also possible that these confrontations radically changed the mindset of the astartes of the time, as the Chapter seems to have reverted to a nomadic lifestyle, abandoning their adopted territory and world: Catorsha.

* **The Undying Legions (112.M37)**: The Chapter was confronted with the emergence of a minor Necron Dynasty in the Eastern Fringe of the Segmentum Ultima. This is officially the oldest official proof of a Necron awakening known to date from the Imperium. The Chapter lost almost the entire deployed company. First mention of the term "Abomination of Living Iron" listed in the Chapter's archives following the trauma of this confrontation and the unknown nature of this species not listed at the time.

* **The Tau Empire (018.M39)**: First meeting of the chapter with T'au specimens. The archives mention an "intrinsic disagreement of point of view that led to the end of the transmissions". It is reported that the fleet encountered was destroyed by the vessels of the chapter and that no further research was carried out in view of the "insignificance of this xenos species".

* **Defence of Ultima Segmentum (350-500.M41)**: Numerous minor engagements throughout the Segmentum. The meager detail of the Archives does not allow for a complete and detailed chronology of this period. However, many scholars agree that it was during this time that the chapter last passed by Catorsha without lingering and abandoned its static mode of operation in order to be able to intervene throughout the Segmentum.

* **Death of Aliendros (700.M41)**: The Chapter was confronted by a large greenskin horde in a sub-sector, not mentioned in the Chapter's records, of the Segmentum Ultima. This confrontation led to the death of Chapter Master Aliendros and the appointment of Ivander Cestius as Chapter leader. The losses reduced the Iron Purity to two Companies after more than three centuries of uninterrupted conflict throughout the Ultima Segmentum. A succession of campaigns to exterminate and pursue the surviving greenskins responsible for Aliendros' death were carried out in retaliation.

* **Simondis Epsilon Campaign (838.M41):** First encounter between the Iron Purity and the Sons of Shadow Chapter. The Forge World Simondis Epsilon is then invaded by a Waaagh! Skins of importance. Faced with the challenge of this new purge, the two Chapters collaborated effectively to free the planet. It was during this campaign that Seraphus Akland met his mentor, who taught him the basics of Sons of Shadow training, essential to his survival behind enemy lines. There is no record of how the overall conflict unfolded or how Seraphus Akland and Alis Irae became trapped by the Orks. This is probably due to the highly secretive nature of the Sons of Shadow Chapter. The chapter archives do not explain the presence of the Sons of Shadow there, nor whether they were contacted by the Iron Purity in the first place.

* **The War of G-18-A-19 (902.M41):** Gathering their forces on the frozen world of G-18-A-19, unknown to the Imperium, a Warband prepares to launch a raid against the Kingdoms of Ultramar. The heretics use a special demonic device to haunt the dreams of the surrounding systems and convince Imperial citizens and soldiers to turn to the Dark Gods in their sleep. Disturbed in her visions by the nightmarish device, the Great Prophetess Daenalli orchestrates the arrival of Hector Adrian's newly promoted company of Iron Purity on G-18-A-19. Supporting the Adeptus Astartes, first from the shadows, then openly, employing a squadron of Fire Prisms to annihilate the heretic base, adding their firepower to that of the Whirlwinds and the Chapter's Land Raider. Despite the Aeldari's initial manipulation, Hector chose to leave without further conflict, complimenting the firepower of their casual allies before leaving, entrusting the Eldar with the Chapter's distress beacon, in case future cooperation is needed with the xenos. Hector adds that he would rather help knowingly than be manipulated.

* **The Treachery of Garonis (099.M42):** The Iron Purity engage in the defense of the Garonis system against a massive greenskin invasion after receiving a distress call from the Garonis Tertius Throatworld. It took six months to repel the xenos, but the losses were great, not from the orks, but from a more insidious threat that revealed itself at the worst possible time. Securing the advance of the first and third companies of the chapter was left to the second company alone, which, while reinforcing the planetary capital of Garonis Prime, was attacked from within by Heretic Space Marines belonging to the traitorous Iron Warrior. This unexpected confrontation resulted in the loss of more than half of the Second Company's strength. The forge world of Garonis thanked the Chapter for its intervention and sacrifice by presenting it with four relic armor models of the Cataphractii Terminator.

* **MN-12a Disaster (100.M42):** Immediately following the conclusion of the Garonis campaign, Iron Lord Ivander Cestius responded favorably to the call for the Crusade in the Venexian sector. Even as the Chapter prepared to depart, a phantom echo on the fleet's omens forced the Iron Lord to exercise caution by changing his original flight plan to a longer one based on tortuous detours between different systems. This decision was motivated by the weakness of the Chapter after the bloody Garonis campaign. This took the Chapter to an uncharted and unnamed system that proved to be home to an awakening Necron dynasty. With the Chapter's fleet initially undetected, a reconnaissance mission to the surface of the newly designated planet MN-12a (Necron World-12th found, system position: alpha). In the time it took to send the reconnaissance force of scout squads, the chapitral fleet was spotted by Necron patrol ships, which gave chase. The Iron Purity retreated, leaving the scout squads behind on the surface of MN-12a. Hector Adrian refused to leave the future of the Chapter behind and disobeyed orders to return to the scene to extract the Scouts from the inferno. Accompanied by Regulus Covis, the Iron Paladin led the assault on the planet's surface and recovered the neophytes and Instructor Sergeant Akland in extremis, escaping with the help of the Chapter's fleet at the critical moment. This event marks the first rift between Hector and Ivander and the arrival of the first Iron Purity Primaries.

* **Incidents of Carcerem (100.M42):** A few months after the disaster of MN-12a and the Chapter's involvement in the Fulminata Crusade, the Iron Purity attempt to pacify the penal world of Carcerem, which is plagued by an invasion of greenskins who fled the Garonis system after the Chapter's passage. Even before the first confrontations, Iron Lord Cestius received confidential information about the probable presence of a chaotic sorcerer orchestrating the revolt of the millions of inmates of Carcerem. In order to get to the bottom of it, Ivander commissioned Seraphus Akland, now a Paladin of SombreFer, a company specializing in assassination, sabotage and infiltration missions, to go and investigate the depths of the planet's prison system. Hector Adrian was assigned to pacify the surface of the Cultist world. It was under these conditions that Confessor Selenna Ivannova of the Ordo Hereticus revealed herself to the chapter, forcing the hand of the Iron Lord and leading to the death of the Iron Paladin Nicodemus Lazar after the decision not to send reinforcements to Hector when he requested them following a massive ork assault on the surface of Carcerem. This event will mark a pronounced distance between a majority of the chapter members towards the Primaries. After a number of close calls, the survivors of the third company rallied Serpahus in the depths of Carcerem and were able to capture the wizard with the help of a Red Rampart Killer. When Hector finally returned to the fleet, he learned of Lazar's death and the loose details of the story. He will make his disgust with Ivander's decisions clear to Ivander and will become Ivander's designated successor for many. While the Iron Lord is paralyzed by indecision between his desire to continue the crusade, at the risk of being accused by the highest authorities of the Venexian sector of being responsible for the loss of Carcerem, and his desire to preserve the chapter by fleeing the sector, fate will show itself to offer him a way out. As the Chapter prepared to flee the Carcerem system, a communication reached the Iron Lord from none other than Lord Commander Roboute Guilliman himself. He orders the Iron Purity to lead a crusading force to liberate a minor sector bordering the Great Rift in the name of the Emperor. The chapter then sets out for the Sarbedia sector.

* **The Betrayal of Sigma (101.M42) +++Data not found+++**

* **Crusade of the Worlds of Sarbedia (101.M42):** Like the many Crusades that have shaped the history and territory of the Imperium, the Crusade of the Worlds of Sarbedia was a vast gathering of disparate forces from across the God-Emperor's domain, especially since it was part of Primarch Roboute Guilliman's Indomitus Crusade. Without the others, none of the Imperial forces present could have succeeded alone. During the campaign, the Imperial forces, spurred on by the Imperial propaganda machine, were dubbed the Saviors, as the first ships gathered at the edge of Chaos-controlled territory. From the youngest recruits of the Astra Militarum to the remarkable Titans of the Collegia Titanica to the devoted and loyal Sisters of the Adepta Sororita to the legendary Battle Brothers of the Adeptus Astartes, the Sarbedia Worlds Crusade enjoyed a variety of fighters, a double-edged sword. Indeed, while variety offers a range of strategies, weapons and thoughts to deal with many situations, it also brings with it the independence of some and the multiple agendas of others. Politics was one of the main internal enemies that the Triumvirate enjoyed during the conflict.

* **The Rediscovery of the Behemoth (111.M42):** As the Sarbedia Worlds Crusade came to a bitter end, the Iron Purity set out for the Sarbedi Gate to regroup and rebuild their forces. During the journey, the fleet had to make a stop to regroup their ships for the final approach to the Catorsha System. The journey went smoothly, but a scan of the transition zone revealed a huge ship adrift. Upon analysis it was a Super-Heavy Cruiser Avenger. The name of the ship was still visible on the hull: Behemoth. An expedition was hastily assembled to explore every corner of the ship with the goal of capturing it to reinforce the Chapter's fleet. This region, lost between two solar systems, was an ideal hiding place, as few Navigators made such a stop to regroup several ships before the next jump. So it was with good luck that the Iron Purity came upon the Behemoth. But capturing the Behemoth was not going to be easy. The cruiser was overrun with hibernating tyranid organisms. The first skirmishes took a heavy toll on the Chapter's vanguard troops. Reinforcements from across the fleet descended upon the super-heavy cruiser to purge its corridors of the xenos that infested them. The purge lasted for days, but all traces of the Genestealers had finally been eradicated. The ship was finally towed into orbit on the moon of Catorsha for extensive repairs. The power of the Behemoth would prove to be a valuable asset to the Chapter's fleet. After the catastrophe of the Home War, the Behemoth was hastily repaired before the Chapter's hasty departure. Although this decision was often questioned by some of the Chapter's officers, any challenges were quelled by the Iron Lord, who argued that it was time to go on the offensive against their long-time enemies. The necessary repairs would be made as the fleet moved and the Forge-Worlds encountered

* **The Field of Steel (112.M42):** Following the Sarbedia Crusade and the loss of Ivander Cestius and Gabriel Cardos, the Iron Purity Chapter found itself greatly weakened. The chapter invited their chapter masters to beatify them alongside the Kings Fangs, who were also mourning the loss of Kalish Clovis. On the world of Caros, the funeral took place, with the bodies or remains of the chapter masters lying side by side in sarcophagi covered by their respective chapter banners. Hector Adrian spoke first, recalling Ivander's inflexibility, both as a leader of his people and during the events in Sarbedia. He said that he had always made the right decisions, that he had always served the interests of the Imperium and the Chapter above all else, until the very end, and that he would make it his duty to follow his teachings with the same selflessness. Following Hector Adrian's speech, a fleet was spotted in orbit and the information was immediately transmitted to the astartes' com-voxes on site. The solemn and truly unique moment that the battle brothers were experiencing had just been disturbed by an unwelcome guest of the worst kind. There was silence until several ships in space were struck by masses of flesh with mouths and fangs. All the astartes drew their weapons and took up defensive positions. The remains of a Tyranid spin had just arrived in the planet's orbit. From the battle barges, the marines battled the xenos ships with some difficulty. Meanwhile, the situation on the planet was even more perilous, as the protection of the bodies of the former chapter masters forced the astartes to hold an extremely disadvantageous position, and many of them fell while defending themselves. Hector was nearly impaled by the sharp limbs of a burrowing creature, but was saved by Harold Merova. The King Fang deflected the attack with a swipe of his blade and sliced open the xeno's torso before moving on to another target. After dozens of hours of fierce fighting, victory was achieved and the Kings Fangs captains present chose Harold to go up to the square where Hector had made his speech and do the same. He had distinguished himself during the Sarbedia Worlds Crusade, and during this battle. Hiccup gave a poignant speech to his brothers, one that resonated in the hearts of the Iron Purity as a reminder of their own condition. After the Kings Fangs' rite of passage was completed, the actual coronation of Ivander Cestius was performed. In the vast foundries of the Redemption's Stars, the body of the former Iron Lord was plunged into the molten metal, slowly sinking and his face sinking into the yellowish flames. The heat around his frozen face clouded the air and some thought they saw a parting smile on Cestius' mouth, one of confidence and certainty. The events and the common celebrations bound the chapters together with bonds stronger than blood, becoming eternal allies in the midst of the endless war. Hector and Harold embraced each other like brothers and pledged their loyalty. A tradition was born, honoring each other's dead as if they were his own whenever the two brotherhoods crossed paths. Each chapter was now willing to do anything to assist the other, even if it meant abandoning their personal goals. The honor of each chapter was at stake, and each meeting between the two chapters was always a celebration, punctuated by ritual duels and the sharing of past exploits.

* **The Home War (113.M42):** After the grueling Crusade of the Worlds of Sarbedia and the campaign of the Steel Field, the Chapter decided to travel to their preferred recruiting world: Catorsha, located in the heart of the Sarbedi Gate. Hector Adrian, newly appointed Iron Lord, wished to establish himself there for a time in order to replenish the Chapter's numbers until it was up to the standards of the Astartes Codex. This decision was seen as the first step towards the renewal of the Chapter envisioned by Ivander Cestius. As the Iron Purity left the Sarbedia Sector to travel to the heart of the Sarbedi Gate to join their recruiting world of choice, the Chapter Fleet spotted strange emissions of unknown energies at the edge of the System as soon as they entered orbit. Before the Iron Purity could react to the strange emissions, a huge black ship with emerald lines and a crescent moon shape appeared before them. Hector Adrian, just elevated to Iron Lord by the Chaplains of his Company, recognized the battle ship as the one he had encountered on MN-12a, and fury seized him. He was both eager to fight and upset, for the sighting of the Cairn ship in this system, so far from MN-12a, could not be a coincidence. It meant only one thing to Hector: The Necrons of this Dynasty had been tracking them since MN-12a and had been waiting for an opportunity to reveal themselves. For Iron Lord Hector Adrian, the space battle was a losing proposition given the firepower of the Starship Cairn and its escort. So he took a risky gamble: lure the Tomb Ship's escorts behind the Catorsha Womb Moon and land all of the Chapter's Companies on the moon's surface to establish a fortified position as only the Iron Purity could do against the Necrons. This, he hoped, would keep the Necrons away from Catorsha and its population, while still having the advantage of position. The Starship Cairn stayed back, not far from the moon, while its many Escort ships chased the Chapter Fleet. Both sides were eager to do battle with each other, eager to get revenge or to finish unfinished business. Once on the surface of the mining moon of Catorsha, the Iron Purity quickly took up position in one of the planet's more isolated manufacturing districts. Almost immediately they received reinforcements from the Mechanicus, who had been there for eons. The Mechanicus did not know that the Necrons' presence was a result of the Chapter's arrival, but that did not seem to matter as the followers of the Cult of the Machine were thrilled to have an opportunity to get their hands on xenos' technology and artifacts. The Chapter had little time to establish and strengthen its defenses, for already, countless Necron legions had set foot on the moon. What followed was a tedious siege in which the fighting did not stop for a second. The staggered defenses held, allowing the chapter to make several retreats and counter-charges with the help of the Mechanicum's machines, and the Iron Purity's habits of supply allowed the Astartes to hold the line without fail. Casualties were still high, however. For every Living Iron Abomination the Iron Purity killed, hundreds more arrived, and hour after hour, day after day, the Iron Purity lines retreated in the face of the living machines' relentless onslaught. On the verge of total annihilation, with their last line of defenses down, the Iron Purity were narrowly saved by the intervention of the Chapter's returning ships, which began a bombardment of enemy positions on the moon's surface. The Iron Purity ships were not alone, however. A large number of ships from the Imperial regiments and the dreaded Knights of Valgast arrived from orbit in a storm of flame and shells to cover the surviving Astartes. The battle was fierce and costly, but the xeno machines inexplicably retreated and left the System in a hurry, while the outcome of the battle was still undetermined, if not in favor of the xenos. What remained of the Chapter took on a much more belligerent and stubborn attitude, convinced that they were being persecuted all the time and that they could not take the years of rest the Chapter needed to rebuild its numbers and reserves.

* **Fleeing Forward (113.M42):** Beyond this point in the story, little is known about the movements of the Chapter as it once again abandoned the Catorsha system. According to the most recent reports from the Inquisition, the Chapter was headed for a deserted system already visited by the Chapter long before the Sarbedia Crusade. These reports do not explain their motives, but assure the loyalty of the Iron Purity. It is likely that, under the impetus of their new Chapter Master, the Iron Purity embarked on a vengeful crusade against all their enemies who had bullied them for centuries. This event was later known as the Vindicta Crusade, and was intended to fulfill the Iron Purity's age-old vengeance against all those who had the audacity to stand in their way.

* **The Vindicta Crusade (115.M42):** No longer able to maintain their nomadic lifestyle, which has offered them many advantages in exchange for losses that are difficult to replace without a fixed base, the Iron Purity are at a low ebb, even with the Primaris reinforcements they received shortly before their arrival in the Venexian sector. Iron Lord Hector Adrian decides to call upon old and new allies of the Chapter to exterminate the xenos and heretics that have been hunting the Chapter for several years now. The first target of this vendetta is of course the Necron Dynasty of the system named MN-12a by the Chapter, and having inflicted a serious setback on them in the heart of what was once the Chapter's domain: Catorsha. This crusade is primarily a way for the Chapter to regain morale and honor they feel they have lost since the Garonis campaign, but more importantly to rid themselves of a serious threat to the Imperium, the Ultima Segmentum and the Chapter. To do this, the Iron Purity must still take the time to build up their strength, so Iron Lord Adrian will plan a tortuous path from the Sarbedian Gate, taking the fleet to safe zones and forge worlds with which they have good trade relations, while sending astropathic messages to their allies. This vengeful crusade was quickly perceived as more personal than altruistic. To this, the Iron Purity vehemently replied that this vengeance was long overdue, after millennia of selfless and costly fighting. This burning desire for revenge was the root of many minor conflicts among the factions involved in the Necron extermination. This uncharacteristic attitude of the Iron Purity would isolate them somewhat from their allies until they felt they had received retribution for their past suffering. However, this attitude changed when they finally approached the Garonis System, the last stop before MN-12a, which had fallen into the clutches of the Amekthar Dynasty from MN-12a several years earlier. As the Iron Purity investigated the surrounding systems, they became aware that the awakening of MN-12a was complete and that the necrons had not remained idle. The Living Iron Abominations had taken over half a dozen systems close to their own, making it difficult for the chapter's crusade to succeed.

## Chapter Organisation

The Iron Purity were strongly influenced by the conduct of the Ultramarines when their Chapter was created. Wishing not to repeat the mistakes of the past, and in a perpetual quest for redemption, they always act in a logical, coordinated and relentless way, taking into account the risk of casualties whether in their ranks or among the civilians of the Imperium that they protect. The Iron Purity do not have a homeworld, their chapter fleet and the battle barge, *Redemption's Star*, serve as a mobile fortress-monastery for the chapter. No one knows where their stubborn refusal to settle on a fixed world comes from.

The Chapter had, until recently, only a total of three companies of 100 Astartes and two Scout Squads. Although this figure is correct, it did not take into account all the Chapter astartes that were assigned to the orders of the various ships of the Chapter fleet. Following the events of MN-12a, the Chapter will undergo a reorganization in depth and an increase in the number of Astartes within it.

### Primaris Space Marines

The newly assigned Primaris Space Marines has a different marking than the one usually used by Iron Purity. Where the chapter identifies color scheme, their Primaris brethren grades via shoulder and/or knee markings, the rank of the Primaris is color-coded on their helmet, leaving the right shoulder pad without any markings other than the various squad specialist icons to distinguish what role a Primaris brother is currently assigned to. This difference in marking is most certainly due to a desire to respect the *Codex Astartes* as heirs of Guilliman. This difference is only one of the causes of the mistrust of certain members of the chapter with regard to the Primaris Marines. Although the majority has accepted their presence, there are still differences, both in terms of tradition and habits that are not concerned with full respect for *Codex*. The Iron Purity Primaris wear on their armor the original gold colour of the Chapter. Those of the ancients, having tarnished with the millennia of existence of the Chapter, lean more towards the bronze to see the orange. On the two Primaris companies, Ivander Cestius made the decision to leave the captains who led them when these reinforcements reached the chapter. They were then named Iron Paladins and were instructed to abandon the old denominations of ranks. Although this obligation had little impact on both companies, most Primaris brethren still make the mistake of calling their Iron Paladin, Captain. On the other hand, it fits very well with the help of Iron Paladin Hector Adrian, the only Iron Paladin to have welcomed Primaris into his Company, and the Dark-Iron Paladin Seraphus Akland, who selected the most promising elements for integrate the company of Dark-Iron.

### Specialist Formations

#### Assault Marines

These battle-brothers are more revered than those who make up a typical Chapter's assault squads. A true embodiment of fury and violence of which an Iron Purity is capable, being part of these squads is perceived as a great honour. They are seen by other brothers as those who bring their just punishment to the enemies of the Imperium with speed and ferocity. The overzealousness with which they slaughter their chainswords in the heart of the enemy's formations can be chilling for the outside observer, as their determination knows no bounds. Within the chapter, they have the highest casualty rate, having the unfortunate propensity to remain more than necessary in the midst of enemy troops. They are therefore used sparingly and only for engagements where their presence on the battlefield will be decisive in the course of the global conflict.

#### Chaplains

Since the Age of Apostasy and the constant confrontation with fallen Astartes Chapters and the Demonic Osts that accompanied them during this period, the Iron Purity have adopted the adage "Better more than not enough". This translates into a number of Chaplains greater than what is recommended by the Codex. Each Chapter Company therefore contains a minimum of two Chaplains, to ensure that the Iron Purity do not fall into the same trap as the Renegades. The control exercised jointly by the two Chaplains also applies to the Iron Paladins of the Company. Each Chaplain must also keep an eye on his colleague. Apart from this particularity, their role does not change and they are always there to respond to the spiritual needs of the Chapter. Each Astartes of the Chapter knows that he can blindly trust these zealots in the service of the Emperor's will. On the battlefield, their imprecations and fanaticism galvanize the Brothers and push them to surpass themselves. Strangely, the Iron Purity Chaplains do not seem to be affected by the frenzy of the Last Stand that other Space Marines suffer when they find themselves cornered and outnumbered. They are probably the only ones who keep a cool head and try to temper the frenzy of their Brothers. They also serve as scholars, charged with educating future generations of warriors in the great Oratorium of Redemption' Star. Recently, more and more Primaris have been attending these lessons on the history of the Chapter and its traditions, making it easier for these new brothers to integrate into the Chapter.

#### "Red Wall" or "Killer"

Specialized training prior to the Age of Apostasy, these Astartes were once specialists in fighting against renegade Space Marines. In the 42nd Millennium there are only a handful within the Chapter and their existence, apart from the other brothers in battle, is full of mystery. The "Killers" wear two distinctive signs on their armour: the black helmet, symbol of their function; and the red-stained gauntlets, the symbol of their mission. Each member of this former formation is never far from a chaplain and never mixes with the other brothers of the Chapter for fear that the horrors they once faced and saw, would corrupt the rest of the Chapter. Doomed to disappear with time, it is not excluded that their talents may be needed again for the Iron Purity, thus postponing the time of their extinction. Each "Killer" takes the *Oath of the Dead*, promising never to talk about what they will see and face to anyone. This vow of silence is also accompanied by a promise of death in battle and far from the Chapter. Rumours have it that only the most dedicated marines were once selected to be part of the "Red Wall" and so it was common for the Assault Marines to finish their service in this specialized training.

### Order of Battle

#### Chapter Companies

Shortly before the Chapter entered the Fulminata Crusade in the Venexian sector, its composition changed drastically with the arrival of the Marine Primaris.

* **1st Company** (Kristaros Domiel - Post Sarbédia)
* **2nd Company** (Regulus Covis - Post Carcerem)
* **3rd Company**  (Astur Reyzor - Post Sarbédia)
* **4th Company**  (Primaris) Aleric Medon; Post MN-12a)
* **5th Company**  (Primaris) Garren Draxx; Post MN-12a)
* **6th Company**  (New Iron) Arald Gotbrand; Post MN-12a)
* **Dark-Iron Company** (Seraphus Akland; Post MN-12a)

This composition will undergo many changes from the Garonis campaign to the Sarbedia Worlds Crusade, as well as the senior officers at the head of each Company, due to the many successive conflicts the Chapter has experienced since MN-12a.

### Company specializations

#### 1st Company

The First Iron Purity Company has always been the one to escort the Iron Lord and see to his safety wherever he is and wherever he goes. This Company will always be part of all deployments and has always specialized in heavy and frontal assaults. It is best equipped and is the only one that can own and use the rare Chapter Weapons and Relic Armor. This company is also the one with the most armor of ancient models such as the Mk3 and Mk4. Each Iron Paladin who has succeeded one another at the head of the First Company has always had a burning character, the first necessity to lead violent assaults head-on.

#### 2nd Company

This Company has always been the backbone of the Chapter. Versatile and adaptable, the Second Company of the Chapter is always the last to deploy in order to assist the other Companies of the Chapter effectively and at the right time. This is reflected in the character of each Iron Paladin leading the Second Company: always ready to assist the other Brothers of the Chapter no matter the danger, no matter the enemy. The late deployment of this Company means that it must also oversee the supply chain of ammunition and equipment to the Companies already deployed. Under the leadership of Iron Paladin Lazar, the Company will become an indispensable part of the other two Chapter Companies. With the Iron Paladin Covis at its head, the Second Company would abandon some of the aspects that made it a supporting force. The burning zeal of Regulus Covis will be passed on to his men, who will be deployed more often as a strike force by Hector Adrian, who is more than confident in his friend Regulus' abilities.

#### 3rd Company

Little is known about the specialization of this Company. It is mostly deployed to break down the defenses of an entrenched target, making this Company experienced siege breakers. This tendency seems to be disappearing with time since the re-creation of the Company with the Iron Paladin Hector Adrian, who pushes his men to be more versatile in order to be able to face all the unforeseen situations encountered by the chapter. However, the Third Company is systematically deployed in the event of a siege and is the only one to make extensive use of the assault modules launched from orbit, and the Chapter's rare armor is always made available to it first. After the death of Iron Lord Ivander Cestius, the Company will wear a black band on the left shoulder of their armor in his memory and as a mark of deep regret.

#### 4th Company (Primaris)

This company has a history of daring suborbital assaults. As a result, Ivander Cestius granted unrestricted access to the Chapter's Thunderhawk shuttles when necessary, although the company already had its own fleet of air vehicles when it joined the Chapter after the events of MN-12a. From then on, the fourth company was used for reconnaissance flights, lightning landings, or targeted bombing operations. Coordination with information gleaned by the sixth company, on the ground, increases the results and accuracy of the operations of this Primaris company.

#### 6th Company

The Sixth Company currently includes all the Scout Squads of the Chapter as well as the Neophytes. Reconnaissance and tactical support are their main tasks within the Chapter. It is often requested by the Fourth Company, in order to provide them with as much information as possible before a lightning intervention.

#### Dark-Iron Company

++ *Access impossible. Locked archives* ++

## Chapter Recruitment

Only the Officers have the ability to select the few potential recruits who will join the ranks of the Chapter. The selected recruits must then complete, among other things, the Ritual of Forging. A challenge in which the Recruit must compete against an Astartes of the Chapter. Only the current Chapter Master, Ivander Cestius, would have beaten the Astartes who faced him when he was a young boy. If the child is deemed too weak, unworthy, or simply has no potential for the Chapter, he or she is either sent back to his or her world within the hour or kept as a Chapter serf. On the other hand, if the child shows talent and reflection in the face of a normally hopeless battle with an Astartes, he or she will be accepted and integrated into the group of neophytes who begin their first psycho-conditioning sessions. Each Neophyte is seen as an extremely valuable resource, and their lives are not wasted. All the brothers in the chapter take care of them without showing it ostensibly.

### Post MN-12a

Following the events on MN-12a and the arrival of Primaris reinforcements, Ivander Cestius decreed that the recruitment of Novices would be less strict in order to ensure the future of the Chapter, where it had almost disappeared on Tomb World MN-12a. From then on, every world with a harsh climate, crossed by the Chapter, was the object of recruiting young boys to be Astartees, regardless of the opinion of the Chapter Officers. This way of doing things made it possible to replenish the ranks of the present 6th Company, to the detriment of a rigorous selection of recruits. Some Officers believe that the strength of the future Astartes will only be a shadow of the strength of the Marines who preceded them.

### Primaris

The recruitment of future Primaris is left to the Iron Paladins Primaris of the 4th Company. This mark of independence from the Chapter is intended to facilitate the integration of the Primaris Marines by entrusting them with the full and complete charge of their Company. This freedom was badly perceived by the Officers who refused their presence among their ranks, sometimes going so far as to question the decisions of the Iron Lord. This tradition will continue under the authority of Hector Adrian and will even be fully encouraged. The Primarist apothecaries were also instructed to pass on information concerning the biology of the Primarists to the older apothecaries of the chapter, in case the Primarist apothecaries were not present to look after their brethren.

## Combat Doctrine

"*We hold, no matter what the storm is, what does the flames matter, we hold a line as well as the sons of Dorn hold a rampart.*"
— Chapter Master Ivander Cestius

The Iron Purity put all their knowledge into the art of siege and the destruction of strongholds in the Segmentum Ultima. Their combat doctrine focuses on static position wars like the Astra Militarum. Artillery shelling and the regular use of heavy weapons, as well as explosives, make them a Chapter as effective in the art of siege as in taking and maintaining position on a conventional battlefield. Although, the Iron Purity compensate for the small number of Astartes deployed in the field by a strong supply line and a highly effective and foolproof logistical support, allowing them to progress in the various theaters of operations they are responsible for.

### The Protocol

"*Nothing is more important than protocol within the chapter. Except maybe the chapter itself.*"
— Chapter Master Ivander Cestius
#### The Confrontation

"*Hector Adrian, Iron Paladin of the Iron Purity. Do you question the commandment of your Lord, Ivander Cestius, Iron Lord of the Chapter?*"
—Nicodemus Lazar
In the event of disagreement between two members of the Chapter having different ranks, a Chapter officer must arbitrate the dispute through a series of ritual questions relating to the nature of the dispute, so that the two parties no longer speak directly but can freely express their disagreements without prejudice to the protocol governing the hierarchy. The problem must therefore be solved, so as not to risk hasty and counterproductive decision-making that would hinder the smooth running of future Chapter operations. The confrontation can be triggered at any time and usually results in a silent face-to-face meeting between the two parties until a third party officer asks the usual questions. It is not impossible that the confrontation could end in a deadlock in this case, an officer's council meets and both parties are deprived of their ranks and privileges until a solution is found. This solution is most often in favour of the most senior officer of the two parties in this very rare case. However, the greater the hierarchical gap, the more misunderstood the confrontation will be by the chapter as a whole. In theory, a simple brother of the rank can therefore confront the chapter master, but the consequences for the brother would undoubtedly be more important than the potential gain.

#### The Judgment

*"By my life and my honor, I defer to your judgment."*

This formula has a very strong impact within the chapter and is only used very rarely, because the person who uses it seeks to make his interlocutor(s) understand his willingness to prove full acceptance of his mistakes and the consequences that result from them. This protocol formula is not used lightly because it allows those for whom it is intended to have the fate of the person who pronounces it. Thus, the one who pronounces this formula, literally risks dying in the minutes that follow.

#### The Greeting

*"Iron Purity"*

Although this sentence is normally the rallying cry of the chapter, it also serves as a greeting. Salvation is used against a superior, a mentor or simply a person respected by the person who employs it. This respect for the Protocol, and for the person being greeted, is widespread within the Chapter. The person greeted in this way, however, is not governed by a mandatory response rule and may not respond with the following formula: "Steel will be our will". Like the answer, salvation is not systematic and can be replaced by a more informal salvation such as the sign of aquilla.

#### The Duty

*"You have done your duty to the Chapter and the Emperor"*

This formula serves, in theory, only as a constant reminder to Iron Purity of their objectives. In practice this formula actually serves to remind the Iron Purity what the original renegade legions betrayed: the chapter being the representation of the Imperium. Thus, whenever a chapter astart thinks it has failed in its duty, when it is not, this formula is there to make it clear that only the chapter, the Imperium and the Emperor matter. However, this is only one of many possible interpretations of this formula. Being the most obscure, and paradoxically the most used of all, it can also be used to honour a Chapter member for outstanding service.

This set of rules may seem unnecessary or considered a waste of time. But the origin of the creation of this strict framework was, above all, motivated by a desire that the chapter should not fall into the same trap as the treacherous legions, should not make the same mistakes as these, and should lead it to betray its oaths.

### The Dubbing

Within the Chapter, a tradition has been going on since its foundation. The Iron Paladins and the Lieutenants, once appointed to one of these posts, are officially recognised as such by the rest of their Brothers once they have been knighted by the two Chaplains of their respective Companies, in a long private ceremony with the two Chaplains as sole witnesses. During this ritual, the future Superior Officer discusses at length with the Chaplains, any subject can be discussed, from the apprehension of the Astartes to find himself in a position of importance, to questions of a more philosophical or religious nature. The two Chaplains take the time to answer any questions and discuss them as Brothers would. Then, the two Chaplains collect the Oaths of Fidelity and Service from the Astartes, which are all the more strengthened once any doubts they may have are swept away by the Chaplains. This tradition can last from a few minutes to several days depending on the individual.

#### The Iron Lords

The tradition remains more or less the same for the Adoubtement of the Iron Lords of the Chapter. Apart from the two Chaplains present in the room, there is also the Lieutenant of the former Iron Paladin, who is dubbed Paladin at the same time as the future Iron Lord. The two Brothers meet for a few hours on equal terms and share their feelings with each other as much as with the Chaplains. The two Astartes take an oath of eternal fidelity in the presence of the two Chaplains, one as Iron Paladin and the other as Iron Lord. Then the ceremony resumes its normal course and this for as long as the two men need.

### Frenzy of the Last Fight

The Iron Purity are only looking for one thing. Death in battle, in the face of an innumerable enemy and alongside a handful of respected brothers. It is only in the face of a similar situation, where there is no longer any hope of escaping alive, that the astarts of the chapter reveal their full potential. Once against the wall, in small numbers, in front of an opponent so numerous that it becomes impossible to count him. Joy seized them, the prospect of the challenge of winning as many opponents as possible before passing through the shoots in a lucid frenzy. The wounds do not slow them down, the death of a brother only reinforces this desire to kill as many enemies as possible. The distance combat is shortened in order to bring the enemy into contact as quickly as possible and this in order to let speak all the violence of which the chapter's battle brother is capable. More than once Iron Purity squads have found themselves in this situation where they should not have been able to get out alive. And yet, as they like to tell it, the challenge was not equal to their talent.

### Hate of the "Living Iron"

All the astarts of the chapter, whether they are veterans or simple brothers in rank or scouts, are affected by a deep aversion towards the Necrons. The strangest thing is that even those who have never faced them directly seem to feed this hatred. Many chapter apothecaries have examined the subject without finding an explanation for this behaviour. Recently, the chapter's chief apothecary, Maximillian Dercius, put forward an interesting theory on this subject. The implants of a marine space are transmitted at the death of the latter, so it is not impossible that the Iron Purity that succumbed, during the first meeting of the chapter with the Necrons, is transmitted through their progenoid glands a kind of heritage of hatred for those responsible for their death. This legacy would then have been passed on from one seafarer to another and would have spread throughout the chapter. Only the Primaris do not seem to be affected by this aversion, reinforcing the credibility of this theory, because they have never shared the genes of the chapter. This theory, although it opens up many avenues for reflection on the emotional transmission capacities of marine space implants, is strongly contested within the chapter itself.

### Recuperators

Since the chapter is based on a fleet and cannot rely on the resources of a dedicated world, Iron Purity spend a lot of time recovering as much material as possible from wherever they can, be it in the still smoking ruins of a battlefield, a drifting shipwreck or on an asteroid, even if it's a bit rich in minerals. It is, in part, for this reason that the Capital Fleet moves in small successive jumps through the warp, hoping that luck is on their side and stumbled upon something worthy of retrieving resources.

## Chapter Gene-Seed

### Additional Information

The recent discoveries of Selenna Ivannova, Confessor of the Ordo Hereticus, in searching the fragmentary Archives of the Chapter, have gathered much valuable information to trace the genetic origins of the Chapter. However, given the importance of this information, the Confessor decided to conceal it after consulting with Ivander Cestius, Iron Lord of Iron Purity at the time. The only tangible information that can be known about these famous discoveries is that the Iron Purity Primaris do not share the same genetic heritage as their non-Primaris counterparts. In order to avoid any further problems, it was decided, in view of the loyalty proven time and again by the Chapter Astartees, to place the origins of the Chapter under the taboo of the Inquisition. As a result, any investigation targeting the Iron Purity will now be impossible, except by a member of the Inquisition who has irrefutable proof of the need to reopen an investigation.

## Notable Personnel

### Seraphus Akland

Formerly Lieutenant to Gabriel Cardos, Iron Paladin of the Chapter's 1st Company, he was the Chapter's Veteran-Instructor of Neophytes. This position was taken by Alis Irae, Captain of the Sons of Shadow Chapter. The two men met during a joint campaign on Simondis Epsilon to destroy a Waaagh! that was threatening the Forge-World. The two astartes found themselves isolated in enemy territory after a greenskin ambush on their detachment. Alis Irae was forced to train Seraphus in the urban combat and guerrilla doctrines of his Chapter in order to survive. Seraphus was reluctant at first, but eventually accepted the teachings of the man who would become his mentor and friend. Upon his return to the Chapter Fleet, Seraphus asked to take over the leadership of the Chapter's Scout Squads to train them in reconnaissance, assassination and ambushes as his mentor had taught him, in order to increase the effectiveness of these vital squads at all levels for the Iron Purity. He would later be allowed to create a company specializing in these areas following the events of MN-12a and would be named Paladin of Dark Iron, granting him the same levels of accreditation as an Iron Paladin. The events in the Carcerem System will have a profound impact on him, both the nature of his mission there and the death of the Iron Paladin Lazar. He would distance himself even more from the rest of the Chapter, reinforcing the special nature of his Company while supporting Hector Adrian's ideals, which he understood although he did not approve of the latter's lack of thoughtfulness in his actions. His involvement in the survival of the Chapter was not to be denied, and Seraphus became a respected member of the Chapter, even by those who did not approve of his methods at first. The lack of discrimination between Firstborn and Primaries in his recruitment to the Chapter made him and his company the glue that held the Primaris together in the Chapter.

### Venerable Tavarre

The oldest member of the Chapter, Tavarre has been locked in a Dreadnought sarcophagus for aeons. He served during the earliest years following the Chapter's inception. Tavarre is also one of the few survivors of the company to which he was assigned during the first meeting of the Chapter with the Necrons in 112.M37. He was then the incarnation of the trauma of this meeting and probably the origin of the nickname "Living Iron Abomination" that the Iron Purity gave to the Necrons. Some battle-brothers even proudly claim that Tavarre fought during the Horus Heresy alongside Roboute Guilliman himself. However, the Venerable Astartes vigorously refutes these allegations, which he himself finds inappropriate and does not fail to point out to those who would be foolish enough to ask him directly. He has been locked up in his sarcophagus for so long that he has rarely come out of his sleep. His most recent awakening in a campaign was during the Garonis campaign. His rest was short-lived, for he is now awake to teach the traditions of the Chapter to the Primaris Marines. He was the one who helped temper the Primaries' ardor after the Sarbedia Worlds Crusade, when they discovered the Necrons besieging Catorsha. He was also the first to propose the idea of a vengeance crusade to purge the Chapter's enemies in order to strengthen the brotherhood and bond between Firstborn and Primaris. Since the Home War, the venerable Dreadnought has been plunged back into a dreamless sleep to relieve the pressure on his mind of such a long life encased in his sarcophagus.

### Ivander Cestius

Iron Lord of the Iron Purity Chapter from 700.M41 until his death on Gemmae in 107.M42, he is the only Chapter Master to have passed the Ritual of the Forge, the most insurmountable test of the Iron Purity initiation. He defeated the Astartes who faced him in the test as a young boy with cunning and uncommon calm for a mortal. The Chapter Master of the time was troubled by this victory which he thought was unexpected. Intrigued by the boy, he talked with him for a long time and concluded that this child possessed a potential the likes of which the Chapter had not seen since its founding. So Iron Lord Aliendros watched Ivander's training and progress very closely. When Ivander was elevated to the rank of Brother, Aliendros integrated him into the Chapter's First Company. It didn't take long for Ivander to rise through the ranks and gain a reputation within the Chapter. Upon the death of the Iron Paladin of the First Company, Ivander succeeded him and led his Company through many conflicts, where his keen sense of logic and absolute calm allowed him to achieve great victories. However, there were tensions between Ivander and the Iron Lord Aliendros. The two Astartes did not see eye to eye on the direction the Chapter was taking. Many heated discussions and debates took place, without ever resorting to the ritual of The Confrontation. This friction ended, however, when Iron Lord Aliendros was killed by a xeno incursion into a darkened Subsector of the Ultima Segmentum. Ivander was consecrated as the Chapter's new Iron Lord and has since attempted to apply his vision to the Chapter while remaining true to the memory of his predecessor. He too will perish, in the Sarbedia sector, from a cohort of chaos demons who ambushed his detachment. The Iron Lord completed his Last Challenge with unimaginable vigor and strength, destroying more than a third of the demonic host almost single-handedly. He was found less than a minute after his last breath by Hector Adrian, who brought him back to the Redemption's Star and honored him with strength and determination.

### Hector Adrian

An Iron Paladin of the Third Company and an accomplished duelist, he was once Nicodemus Lazar's Lieutenant before being chosen by Nicodemus Lazar and Iron Lord Ivander Cestius to lead the newly formed Third Company. Quiet and thoughtful by nature at first, the many cold decisions involving the lives of his brothers motivated Hector to assert himself against Ivander and his vision for the future of the Chapter. Hector Adrian rebelled against his lord's impartial decisions on more than one occasion, challenging his authority for the first time during the events of MN-12a. But it was on Carcerem and the death of his former friend and mentor that Hector would openly confront his vision for the future of the Chapter with that of Ivander, sometimes to the point of insubordination. In the years that followed, Hector became the representative of the resistance to the injustices created by Ivander's choices and the face of a more secure future for the Chapter. Seeing his most promising and respected son die in this way plunged the Iron Lord into a deep melancholy that would not leave him until the day he died on Gemmae during the Crusade of the Worlds of Sarbedia. It is only after being named Iron Lord upon Ivander's death that Hector realizes that every decision of his predecessor was only meant to put the Chapter on the right track with Hector at its head, realizing then that their points of view had never been opposed, Ivander's being much more long-termist than Hector's. This achievement would elevate Ivander Cestius to the rank of Hero and Savior of the Chapter under the impetus of a grateful Hector who was saddened that he had not understood the sacrifice of the man he called "Father" until it was too late. As Iron Lord, Hector would lead the Iron Purity into difficult campaigns just as the Chapter needed a break to refuel and rebuild. This would not happen until after the Vindicta Crusade, many years after his appointment as Iron Lord.

### Noctor Videlis

He is probably one of the oldest members of the Iron Purity not encased in a Dreadnought Sarcophagus. For almost 500 years, he has held the important, yet unofficial, rank of Protector Colossi. This role means that he is responsible for keeping watch over the Iron Colossus at all times. Noctor's job is to follow the Colossus wherever it goes on the battlefield and make sure that the ancient Automaton does not fall into the hands of the enemy, whoever it may be, when the day of its deployment comes. He is one of the most mysterious and discreet characters in the Chapter, rarely appearing outside the deepest Manufactorums of Redemption's Star. His first appearance in several centuries, outside the corridors of the Battle Barge, was during the Sarbedia Worlds Crusade, at the Siege of Elemant. His presence was required as the Iron Colossus had to be deployed to protect Iron Lord Ivander Cestius and the 1st Company of a Corrupted Knight, who were sweeping through the ranks of the Loyalists, who were attempting to take down Fort Dust, a major stronghold of the old Knight World. The Iron Colossus was dropped from low orbit, followed closely by Noctor's Drop Pod. Once there, he transferred control to the Iron Lord and stayed in the automaton's wake as it confronted the Chaos Knight. That day, every battle brother within sight of the Protector could see what a formidable warrior he was, boosting morale and ensuring victory over Elemant.

### Issator Carnaan

The current Master of the Forges of the Chapter, he is the holder of a knowledge and a wisdom proper to an Astartes of his age. No member of the Chapter is more respected than him. Even the Iron Lords know how to listen to his advice or his old stories. A Techmarine for almost 900 years, he has been responsible for many of the Chapter's innovations, such as the Ferrum Cohortis, responsible for the defense of the Fleet Ships, but also for the maintenance and improvement of all Chapter equipment. Issator Carnaan has his own philosophy of the Cult of The Machine. For him, The Machine is not a conscious mind, but an inanimate construct that only works if it is used properly, without recourse to prayers or other blessings. However, the old Techmarine is wise enough not to boast of this way of looking at things. So he applies the principles of the Mechanicum daily to the equipment of the Chapter. But he never misses an opportunity to study the reactions of the Machine Spirits to support his theories. His greatest challenge will be the unpredictable reactions of Hector Adrian's old armor.

## Deathwatch Members

Over the millennia of the Chapter's existence, very few Iron Purity have joined the ranks of the Deathwatch. The few who have left the ranks of the Chapter to join the xeno killers of the Inquisition have returned in even smaller numbers.

* **Athos Zurion:** *Fate unknown*. He was a ruthless Assault Marine and joined the ranks of the Deathwatch, quickly noticed by his superiors for his talent in bringing death to Xenos. He never returned to the Chapter and the Inquisition says it does not know what happened to him. It is not to be excluded that Athos decided to continue his service for an indefinite period.
* **Zuriel Codeus :** *Alive*. Marine Devastator of the Chapter. He served in the Deathwatch with zeal and returned to the Chapter after 50 years of absence. He brought back with him all the equipment that was allocated to him there. His return was greatly appreciated as he brought with him a great deal of knowledge about the Xenos and his own experience in eradicating them.
* **Tivius Pratal:** *Alive*. Chapter Tactical Marine. The veteran of the third company was sent to Deathwatch at his own request. The astartes was destined to become a talented officer at the head of his company. Indeed, his pragmatism and coolness made him a very prominent Iron Paladin among the other officers before his departure.

* **Delos Bellator:** *Alive*. A respected Assault Marine of the Chapter, this veteran of the Third Company was sent to Deathwatch to bring the fury of the Chapter's Assault Marines to the Inquisition. A respected veteran, he doesn't seem to be as zealous as the chapter's other assault marines, but much more fraternal. A charismatic commander who cares about the needs of the brothers under his command, he was popular with the chapter's previous Iron Lord before Ivander Cestius took command following his untimely death. Delos distinguished himself on numerous occasions within the Deathwatch, and returned to his homeland as Champion. Although silent on what earned him such an honor, Hector Adrian also granted him this special status within the chapter, confident that the veteran had not earned this title without reason. Delos was to become the mentor of a new generation of aspirants, in whom he placed the hope of a better future for the chapter, as well as a chance for redemption.

### Exiled

* **Brother Cassius:** *Living*. One of the last representatives of the Red Rampart, Brother Cassius left the Chapter's fleet after the Home War. Too aware of the danger facing the Chapter, he abandoned it in search of the one person who could turn the tide: Confessor Selenna Ivannova. Since then, Cassius has been protecting the Confessor, who is doing everything in her power to help the Chapter survive by providing information, materials and targets.

## Chapter Relics

### Iron Colossus

This Android was discovered in M33 by the Chapter during the exploration of a Great Crusade Iron Warriors complex, uncovered following the devastation of the Beast War. The Colossus model Battle Robot would appear to have been the model for the design of the Iron Circle of the Primarch of the Fourth Legion due to its age. This Colossus Battle Robot has never been deployed by the Iron Purity since its discovery until the Sarbedia Worlds Crusade. Instead, it has undergone a series of procedures to ensure that no problems would arise during the Automaton's hypothetical future deployment. Recently, the Master of the Forges has been working on modifications to the chassis to increase the size of the Iron Colossus and thus increase its destructive potential. The robot is considered a true relic from the era of the Great Crusade.

### Cataphractii Armour

Because of its isolationist nature, the Chapter has little contact with other structures in the Imperium. As a result, the Iron Purity obtain supplies from minor Forge Worlds along the way. In exchange for various services, ranging from the conquest of neighboring systems to the defense of the Forge World itself, the Iron Purity obtain weapons and energy armor. This explains why the Chapter currently possesses only a few Dreadnought Tactical Armors, the latter being of the ancient Cataphractii design. Recently, the Chapter has been forced to come out of isolation to join the ever-increasing battle, requiring all available forces. The Iron Purity had no choice but to be much more exposed to the fighting of the Fulminata Crusade, despite being on the periphery of the main battles on San Tarkus and the other worlds of the sector core. This exposure will quickly make them realize that their equipment must be renewed at the risk of losing effectiveness.

### Indomitus Pattern Armour

After the Chapter arrived in the Sarbedia sector to take the lead in the crusade to reclaim its worlds, the Iron Purity were given twenty pieces of Terminator Indomitus armor by envoys from Mars, as a thank you for their heroic actions at the start of the crusade, but also to seal the collaboration between the Chapter and the Martian Mechanicum for the bloody battles to come. This material was gratefully received and allowed the reinforcement of the first company to become, finally, the Iron of Lance that the Chapter needed. These armors are seen as a blessing and are revered as holy relics. They are all stamped with the seal of the Sarbedia Crusade, the Mechanicus and the Chapter. These armors can only be inspected and repaired by the Master of the Forges Issator Carnaan, as he alone is trusted by the brothers of the first company to maintain their equipment. Unfortunately, many of these precious relics were lost during the Home War and their loss is mourned daily by the red-robed followers and Techmarines of the chapter. Repairing and recovering spare parts for this armor remains a priority for the chapter.

### Ferrum Cohortis

Since taking office, Issator Carnaan has been collecting spare parts and other components to create Automatons that he will name Ferrum Cohortis. These Combat Robots are used only for the defense of the ships of the Chapter Fleet and more particularly the Redemption's Star. Invisible to anyone, they are hidden in the walls via containment hatches and only come out in the event of a boarding of the ship to support the Astartes and crew members on board. Their estimated number is fifty units on the Chapter's Battle Barge alone. Technologically unsophisticated and devoid of control AI, the Automata are all connected to an auxiliary control center under the supervision of the Master of the Forges himself. The armament of these Automatons varies considerably from one unit to another and does not seem to follow any predefined logic. It can range from Laser Rifles to melee weapons or more sophisticated weapons such as the Energy Fist or Plasma Launcher.

### Artifact Collection

During the various battles against the Living Iron abominations, the Iron Purity quickly realized the value of saving Necron weapons and carcasses in order to have powerful arguments for future exchanges with the minor Frog-Worlds that the chapter crossed. This allowed the Iron Purity to recover weapons, ammunition, spare parts and armor as well as their interviews with Mechanicum representatives on these worlds, who were only too happy to get their hands on such rare and valuable artifacts. Although the Chapter's stock of Necron spares is extremely limited due to the difficulty of obtaining them, each piece of technology traded in helped the Chapter secure its future in terms of equipment. This saving grace for the Iron Purity is undervalued, however. Indeed, the chapter prefers to trade its rare parts for a lot of low-value Mechanicum equipment rather than hope for high-value, hard-to-produce imperial equipment, although some Forge-worlds seemed willing to do so. This devaluation allowed the chapter to maintain excellent relationships with minor forge-worlds in the Ultima Segmentum.

### Cestius' grief

After the heroic sacrifice of Ivander Cestius, his armor was recovered and fully repaired. However, the machine mind of this ancient Cataphractii model had become deeply refractory. Indeed, when this relic was given to Astur Reyzor, the new Iron Paladin of the Third Company, the spirit of the machine rebelled and the harness became unusable by Reyzor, as it deactivated itself and became impossible to restart as long as the Iron Paladin was wearing it. The techno-priests hypothesized that the machine's mind had been traumatized by the death of its former wearer, but proposed to solve the problem by manipulating it in a way that only the Mechanicus could. Hector Adrian emphatically refused, preferring to let the spirit of the armor machine mourn like every brother in the chapter. The ceramic plates were then repainted black and the terminator armor was put on display in the heart of the Iron Halls of the Redemption' Star. It is said that the "Mourning of Cestius" will only be worn by an astartes with the same steely will as Ivander Cestius. Some of the brothers in the chapter advised Hector Adrian to attempt to don the armor, convinced that the Iron Lord was the worthy successor to Ivander's will, but he refused without explaining his reasons. Whether it was for fear of being rejected by the spirit of the machine and losing some legitimacy as Iron Lord, or for fear of not feeling truly worthy, Hector Adrian did not seek to approach the armor, which patiently awaited its next wearer.

## Chapter Relations

### Allies

"*Our enemies are far more numerous than our allies, but the strength of the few we can rely on far outweighs the strength of those who seek our downfall.*"
—Hector Adrian
* **Kings Fang:** Whether during the conflicts of the Crusade of the Worlds of Sarbedia or during the Beatification of Ivander Cestius and Clovis Kalish, the Iron Purity deeply respect the nobility and unwavering will of the sons of Kalaris. Both chapters sealed oaths of friendship and mutual assistance several years after the Crusade, and the Iron Purity seem less pessimistic in the presence of their brothers King Fangs. In battle, the two chapters complement each other, adapting perfectly to each other's habits, making defeat virtually impossible when the two chapters cooperate during a campaign, and limiting losses.
