"*Follow me if I advance! Kill me if I retreat! Avenge me if I die!*"
— Lictor Ivan Gardorian, as the Blades of Dorn Chapter entered the Eye of Terror during the Penitent Crusade of Vengeance (112.M38)
The **Blades of Dorn** are a proud Chapter descended from Imperial Fists lineage, created as a part of the 12th Founding during the tumultuous centuries of the Nova Terra Interregnum during the 35th Millennium. This was a period of extreme unrest and civil strife, when the Imperium of Man had been split in twain. The Ur-Council of Nova Terra no longer recognised the rule of the High Lords of Terra and had seceded from the Imperium of Man, forming their own empire in the Segmentum Pacifiucs. This period of divided rule would last for nine standard centuries.

During this time, there were multiple foundings of Space Marine Chapters created to counteract the many outside threats to the unstable borders of the Imperium during this tumultuous period in Imperial history. The Blades of Dorn were one such Chapter, created to help provide much-needed security to the borders between the Segementum Pacificus and the Segmentum Solar. Since their inception, this Chapter has earned the respect of their forebears through their courage, battle-prowess, and centuries of service in the Emperor's name. However, there once was a time that the Blades' loyalty was called into question, for it is to the Chapter's eternal shame that they are successors of the formerly loyalist Crusaders of Dorn, who were corrupted after entering the Eye of Terror in 321.M37, as part of the ill-fated Abyssal Crusade, and reemerged centuries later in 112.M38, as the Chaos Warband known as the Brotherhood of Lethe.

## History

The Blades of Dorn were created during the turbulent era of the Nova Terra Interregnum when the Imperium was split into twin interstellar empires when the Ur-Council of Nova Terra had denounced the High Lords of Terra and claimed rule over the Segmentum Pacificus. This Age was marked by ongoing civil wars for reunification and disputes over old trade terms, tithes, and wavering allegiances. During this period, multiple Foundings of Space Marine Chapters occurred during this centuries-long period of civil unrest. One such Founding was the 12th Founding, which occurred sometime during the ninth century in the 35th Millennium. The Blades of Dorn was one of several Adeptus Astartes Chapters created during this time. However, few records remain regarding this particular Founding which was believed to have come to pass to counteract the rapid erosion and contradiction of the Imperium's borders during this period.

Most of the cadre of the newly created Blades of Dorn were drawn from the 1st Veteran Company of the Crusaders of Dorn, a Chapter that was predisposed towards aggressive and bold styles of warfare, dispatched from warzone to warzone in order to battle Mankind's enemies. During the Nova Terra Interregnum, the Crusaders of Dorn were one of the most highly active Chapters prosecuting the Nova Terran secessionist forces, as well as responding to various emergencies and adding their strength to multiple ongoing conflicts, often tipping them in the Imperium's favour. They were eventually recognised by the High Lords of Terra for their efforts and were found worthy of begetting a new Chapter from their genetic stock. The Blades' first Chapter Master was a bellicose and brutal warrior named Saul Invictarius, the First-Captain of the Crusaders of Dorn Chapter. He was chosen for his zealous prosecution of his duties and strategic brilliance to lead the newly created Chapter. Though oftentimes he was regarded by Imperial authorities as a bitter and hubristic individual, he was an undoubtedly competent commander whose personal valour was second to none.

Soon after their inception, the Blades of Dorn would claim the Feral World of Ostiarius as their new Chapter homeworld. Ostiarius was a planet whose human population was segregated into militant city-states that had only recently developed the use of gunpowder weaponry, making their home an opportune recruiting ground. Constructing their fortress-monastery on Ostiarius' moon, the Warden, the Blades began to recruit from the Ostiarian populace, eventually setting out into the galaxy to prove themselves to their progenitors, their fellow Scions of Dorn Successor Chapter and their Primarch. In the aftermath of the Reign of Blood in M36, the enemies of the Imperium had taken advantage of the turmoil and advanced farther into Imperial space, and thus the Blades of Dorn had their work cut out for them. Aggressively challenging the enemies of Mankind, the Blades became known for exploits such as the eradication of the Cult of the Unclouded Eye, the purge of the Chaos-corrupted world of Rygel V, and the defeat of the Aeldari Corsairs known as the Hands of Khaine, just to name a few. Soon, tales of the Blades' battles were becoming known throughout the greater Imperium.

###  The Years of Shame

Nearly three millennium passed, and the Blades of Dorn established themselves as a rising star among the more recently founded Chapters of the Adeptus Astartes. Honourable to their allies and implacable to their foes, this Chapter's valiant record might have seen them eclipse Chapters of more ancient provenance and heritage in time. But just as the Blades of Dorn were at their highest point, they were suddenly brought low by devastating news. The Crusaders of Dorn, their own progenitors, had been declared *Excommunicate Traitoris* after taking part in the massive Imperial Abyssal Crusade in 321.M37. It is unknown what they endured during their sojourn into the Eye of Terror, as Chapter after Chapter fell to the perils of the Eye, for the Abyssal Crusade had entered a hell from which very few emerged unchanged. The true account of what occurred within the Eye to the Crusaders of Dorn is unknown, but by the time they made their way back into realspace many standard centuries later in 112.M38, this once loyal Chapter was no more, for they had become the warband of Chaos Space Marines known as the Brotherhood of Lethe, wholly dedicated to the service of the Ruinous Powers.

While an early founding Imperial Fists Successor Chapter going renegade was a serious blow to all the scions of Dorn, it was particularly hard for the Blades, and not just because of the shock and feelings of betrayal that came with the report. The Inquisition quarantined off the Ostiarius Sub-Sector, placing the Blades of Dorn under the custody of the Ordo Hereticus to investigate them for potential heresy. Many felt at the time that the Crusaders of Dorn's corruption could have been a result of a deficient gene-seed, and as the Crusaders of Dorn's progeny, the Blades of Dorn were made out as potential conspirators. Of course, the Blades chafed at such accusations, refusing to submit to the Inquisition's screening and defiantly stating that they were no heretics. This defiance however only further convinced the Inquisition that the Blades of Dorn had something to hide, and many Inquisitors clamoured for the destruction of the Crusaders of Dorn's 'corrupted' bloodline. Tensions ran high, and no doubt the two factions would have come to blows if the Imperial Fists themselves had not intervened.

The Imperial Fists arrived upon Ostiarius to meet with the Inquisitorial representatives and gave them their proposal. Chapter Master Bronwin Abermort personally vouched for the purity of the Blades of Dorn and proposed a solution to their dilemma. Abermort offered to test the truth of the Blades' conviction by interrogating one of their numbers through the use of their own Pain Gloves aboard their mobile star fort *Phalanx*. Ivan Gardorian, the current Chapter Master of the Blades at the time, offered himself, personally, to be tested. Admiring his resoluteness, Abermort had his fellow Chapter Master taken aboard *Phalanx* and secured in the archaic device. During his interrogation, Gardorian maintained that his Chapter was innocent, even while being tortured by the Imperial Fists' most skilled Castellans. While the majority of Dorn's lineage deemed this sufficient proof, the Inquisition was still not convinced. To truly prove the innocence of their Chapter, the Inquisitorial representative argued, the Blades of Dorn would be forced to undergo a Penitent Crusade through the Eye of Terror, to prove their loyalty to the Imperium by braving the temptations of the Ruinous Powers without succumbing to it's corrupting influence. If they managed to return uncorrupted, all charges against them would be dropped.

The Blades of Dorn held an emergency council to discuss the proposed Crusade, and after scant hours of debate, they acquiesced to the Inquisition's demands. They concluded that martyrdom was preferable to an existence of suspicion and doubt. They would not dishonour their Primarch, and would not be judged by their fellow Scions of Dorn as found wanting. The Blades of Dorn gathered their forces and in a solemn procession of Battle Barges and Strike Cruisers, they passed through the Cadian Gate and disappeared into the iridescent dust nebulae that surrounded the Eye of Terror, and entered that hellish realm of Chaos.

###  Penitent Crusade & Vindication

Little record of the actions or whereabouts of the Blades of Dorn since they launched their Crusade exist within the Imperium's archives, but there were unconfirmed sightings of the crusading Blades on numerous battlefields around the Fortress Worlds of the Cadian Gate fighting against the Forces of Chaos. It was reported that elements of the Chapter appeared in force to take the fight to their hated enemies on every possible occasion, and once victory was achieved, they would disappear yet again back into the Eye. Once thought destroyed, the Blades of Dorn finally resurfaced near Cadia, battered, but still fighting their long war against Chaos. It was their Chapter Master, Ivan Gardorian, who ordered the Chapter out of the Eye after a subjective twenty standard years of combat against the Traitor Legions. Gardorian saw the toll that the Eye was taking upon his brothers and decided to end their Penitent Crusade of vengeance against the Forces of Chaos. To the Blades of Dorn's surprise, though only twenty standard years had passed for them in the Eye, almost eighty had gone by in realspace. Such is the all-too-common time distortion effects of the Warp.

The Imperial Fists were notified by the Blades themselves of their re-emergence from the Eye of Terror. The Chapter's mobile star fort, *Phalanx*, alongside an Inquisitorial escort, was despatched to Cadia forthwith, and the Blades of Dorn were granted an audience with their genetic forebears. The Blades were detained by the agents of the Ordo Hereticus and tested for the taint of Chaos. Enduring scrutiny from both the Inquisition and the Imperial Fists, the Blades of Dorn passed every test - physical, mental, and spiritual. They were not found wanting and were deemed uncorrupted. Satisfied by this news, the Inquisition formerly absolved the Blades of their progenitor's sins and granted them the Emperor's forgiveness.

It was further agreed that the truth of the Blades of Dorn's gene ancestry would, forevermore, be kept from future generations of Blades of Dorn Battle-Brothers, as this revelation would no doubt break the resolve of the already battered Chapter. The Blades of Dorn had successfully returned from the Eye, having cleansed over two dozen worlds, and with nearly half of their overall forces destroyed. Despite their sojourn into this hellish realm of Chaos, they had returned alive and still devoutly loyal, nonetheless. Deemed free of corruption, the Blades of Dorn were welcomed back into the Imperium's fold with open arms. The Imperial Fists even lent the depleted Blades stores of their own gene-stock to not only help them to rebuild their shattered Chapter but also to instill the purest bloodline of Dorn within them. The Blades were also gifted arms and equipment from the Imperial Fists' vast stockpiles to rebuild their stores of sorely depleted war material. Since their penitent crusade, the Blades of Dorn mainly focused on rebuilding their Chapter, determined to raise themselves to their former heights of glory.

## Chapter Homeworld

###  Ostiarius

The Blades of Dorn's Chapter homeworld is the feudal realm of Ostiarius which is located in the eastern reaches of the Segmentum Pacificus near the borders of the Segmentum Solar. It is within close proximity of the Sanctum, the home world of the White Templars Chapter. Discovered long ago during the Dark Age of Technology, it is a planet made up of an assortment of feudal lords and various kingdoms.

###  A Call to Arms

Permeating the myths and legends of cultures the world over, the stories of knights are a cherished tradition among the inhabitants of Ostiarius, many of whom revere the noble warriors as personifications of glory, righteousness, and the will of the people. Countless knightly orders serve distinct lords, causes and philosophies. Regardless of their exact means, heroes from all backgrounds and nations can serve as knights, hailed as harbingers of exaltation in life and immortalised as legends by their dedicated followers.

Knights often dedicate themselves to the honour of their homeland and the glory of their kingdom. These patriots defend their nation against outside threats or travel the world to spread the influence of their people. Knights who swear their allegiance to the same lord must often work together to achieve goals greater than themselves, though not all such alliances unite knights without strife, and even those who fight under the same banner might not see eye to eye because of ulterior motives. Philosophy can be as much of a motivator as religion or patriotism, and many are the crusaders who fight for a specific cause with no allegiance to god or country. Whether seeking self-perfection through trials of goodliness or delivering the iron fist of law to ignoble miscreants, knights dedicated to disseminating a particular way of thinking can be found acting alone or in large groups.

Of all the motives behind knighthood, honour is perhaps the most ubiquitous as well as implicit. Many are the soldiers who bear a sword as well as a grudge, and those who wish to prove their honor-whether to their people, their nation, or themselves - need to look no further than the path of the knight. In addition to the aforementioned calls to arms, many knights follow a path defined by a particular quest, whether this expedition's mandate is divine, royal, or self-imposed in nature. A knight who dedicates her life to a singular goal or purpose is steadfast in her ways and may journey her entire life in pursuit of such a quest. Although some knights make their odysseys in pursuit of a vile monster or some holy relic, there are those whose voyages are a simple search for wealth and treasure. Knights in search of monetary gain typically do so for the sake of their kingdom or their knightly order and donate their valuable findings to the cause they believe in.

###  Chapter Recruitment

Anyone aspiring to join the Blades of Dorn will have to earn it. First, they will have to attract one of the Chapter's many Chaplains' attention through some valorous deed or trait, such as prowess of arms, undaunted bravery, a thorough belief in chivalry or unerring piety in the God-Emperor. Once a Chaplain has noticed such persons, they will have to impress him with their adherence to a strict code of behavior. They must be just, loyal, courteous, generous, and, most importantly, reverent; they must protect the poor and weak, and never deny protection to a lady or maiden; they must remain clean and chaste in spirit and in flesh (though it is permissible to love from afar); they must strive for candor and flee from pride; and they must face death at all times with courage and good bearing.

Although the Chaplains are not foolish enough to believe that all of these initiates can live up to this code all of the time, they will not extend an invitation to undergo the Chapter's Trials of Initiation to anybody who displays more than minor variations from these standards. These standards are interpreted as the Code of Dorn. The code is rooted in a deep faith in the God-Emperor, in the beneficence of a special order, and in the belief that a warrior proves their worthiness only to the extent that they serve an ideal greater than themselves.

## Notable Campaigns

* **The Nova Terra Interregnum (Unknown Date.M35)** - The Imperium of Man fractures into two interstellar empires, when the Ur-Council of Nova Terra dismissed the High Lords of Terra and claimed separate rule over the Imperium's worlds of the Segmentum Pacificus. The Blades of Dorn were one of several Chapters called upon by the High Lords of Terra to mobilise to this troubled region of the galaxy to help counteract the rapid erosion and contradiction of the Imperium's borders. Fighting alongside the elder Ultramarines Successor Chapter - the Wardens of Orask - and their fellow Scions of Guilliman - the Imperius Ravagers - this powerful triumvirate deployed from one warzone to the next, fighting against secessionist forces as well as adding their strength to multiple ongoing campaigns. These three Chapters helped to tip the balance of several conflicts in the Imperium's favour.
* **Castigation of Aetius (345.M36)**
* **Defence of Amasis VII (389.M36)** - Elements of the Blades of Dorn Chapter joined with the entirety of the Ebon Knights Chapter to combat a huge Aeldari strike force that was assaulting the world of Amasis VII. The two Chapters were seriously outnumbered by the Aeldari forces. When all hope seemed lost, the Blades of Dorn reluctantly pulled out their sorely-depleted forces after sustaining heavy casualties in the open phases of the conflict. They promised to bring nearby reinforcements from their Chapter as soon as possible. For five days the Ebon Knights valiantly fought alone, holding the Aeldari at bay. The Ebon Knights' Knight-Commander, Renannius Cole, held a breach in the Imperial lines, slaying two Aspect Warrior Exarchs single-handedly. The Aeldari prepared to launch their final assault on the beleaguered Space Marines when reinforcements finally arrived. The sky of Amasis VII was filled with Blades of Dorn Drop Pods. Soon the two Chapters fought in tandem which altered the course of the battle and destroyed the Aeldari forces completely. After the fighting, the Blades of Dorn praised the Ebon Knights' courage and tactical prowess. Both Chapters formed strong bonds of friendship and brotherhood during this campaign.
* **Siege of Velorum Prime (405.M36)** - In 400.M36, the civilised world of Velorum Prime was lorded over by the megalomaniacal Planetary Governor Doros Vidius, who ruled the planet with an iron fist. He led a violent and cruel regime and often exercised his sadistic tendencies on those that displeased. Many Imperial scholars believe that Vidius' behaviour was the result of daemonic possession or that he was a willing follower of the Dark Gods. Shortly after he rose to power through various nefarious means (such as extortion and murder) he declared his world's independence from the 'tyrannical rule' of the False Emperor and personally insulted the Master of Mankind. He also (allegedly) sacrificed thousands of Imperial officials to his patron daemon. The actions of such a disreputable individual could not stand. In response, the local Segmentum Imperial High Command send several detachments of elite Tempestus Scions to quell the world-wide uprisings, but became bogged down in the deadly urban warfare fought within the planet's vast mega-city sprawls, which had been preparing for several years for just such a response from the Imperium. The conflict quickly bogged down into a stalemate, as both sides became deadlocked in a conflict that saw no end in sight. After nearly five years, the High Lords of Terra decided that enough was enough, and so, they sent official orders to both the Blades of Dorn and Tempest Knights Chapters to help bring the ongoing conflict to a decisive conclusion. When word reached both the Tempest Knights and the Blades of Dorn of Vidius' cruelty and heretical practices, both Chapters immediately mobilised for war, intent on crushing the rebellious Planetary Governor's rebellion. When both Chapters arrived in-system, they immediately held a war council to decide on how best to proceed. Both Chapter Masters expressed their desire of having the honour of personally slaying the heretic governor, and discussed their plans until they both came to an accord. Since the Tempest Knights were the senior Chapter, the Blades acquiesced and agreed to grant the venerable Chapter the honour of leading the assault on the governor's palace. By dawn the following day, the Tempest Knights launched an orbital assault on the heavily fortified capital. Meanwhile, both Chapters teleported their elite 1st Company formations directly into the heart of the palace itself, while the rebellious planetary forces were distracted by the Tempest Knights' initial orbital assault. The Terminator-armoured elite cracked open the supposedly "unassailable" palace and proceeded to massacre the governor's rebellious forces. Outmatched and outgunned, the mortal soldiers were slaughtered in a hail of assault cannons and storm bolter fire, and slashing lightning claws. Fighting their way to the governor's command bunker, the Veteran Marines slaughtered all those that opposed them and broke their way inside, past the bunker's formidable defences. Once inside, the Chapter Master of the Tempest Knights personally slew the heretic governor and took his head as a grisly trophy. After flensing the head of the slain governor and dipping it in gold, he sent the gruesome trophy by Space Marine envoy to the Segmentum High Command. Upon the gleaming surface of the brilliantly shining gold-plated skull were etched the Tempest Knights Chapter Master's words, "Thus, perish all traitors to the Emperor."
* Assault on Drusus (587.M36)
* **The Clovis Rebellion (112-114.M37)** - When a Black Crusade is launched in the Clovis sector, a joint-Astartes strike force is sent to quell the five worlds that have become overrun by bloody insurrection. The Clovis Rebellion quickly escalates when a large force of Night Lords Heretic Astartes arrived and the Planetary Defence Forces of Clovis Prime crumbled. The Blades of Dorn, Blood Vultures, Brazen Lions, and the Ebon Knights launched a counter-attack to secure vital Imperial artefacts before *Exterminatus* was declared. It takes the three Chapters two more years of brutal conflict to cleanse the rest of the sector's worlds before they are declared free of corruption.
* **Penitent Crusade of Vengeance (112-192.M38)** - When the Blades of Dorn's genetic forbears, the Crusaders of Dorn, are deemed *Excommunicate Traitoris* following the events of the Abyssal Crusade in 112.M38, suspicion and doubt fall upon their progeny as well. Despite having their integrity and loyalty brutally tested by the Imperial Fists themselves, this is not deemed a good enough reason to allay the suspicions of the Ordo Hereticus. Therefore, the Inquisition forces the Blades of Dorn to undertake a penitent crusade into the Eye of Terror itself. Should they successfully prosecute this nigh-suicidal task, and emerge uncorrupted from this hellish realm, they would be deemed loyal and saved in the eyes of the Emperor. With no other recourse, the Blades of Dorn set course for the Cadian Gate, and then disappeared into the hellish realm of the Eye of Terror. Nearly eight decades later, the battered Blades of Dorn Chapter fleet once again reemerged into realspace near the Fortress World of Cadia. They were reunited with the Imperial Fists and granted an audience aboard their star fort *Phalanx*. They were detained and thoroughly tested by the agents of the Inquisition, both in body, mind, and soul, and were not found wanting. Satisfied, the Inquisition absolved the Blades of Dorn Chapter of their progenitor's sins and granted them the Emperor's forgiveness. The Blades had successfully purged more than two dozen worlds within the Eye but had lost nearly half their number in the process. To help assist them in rebuilding their shattered ranks, the Imperial Fists granted them some of their own genetic stock. This was both symbolic as well as practical, as the Blades would now receive the purest of Dorn's bloodlines, which would help tie them closer to their genetic forebears, as well as absolve them of the tainted gene-seed of their corrupted progenitors. The Imperial Fists also provided some of their most ancient relics, arms, and equipment to help rebuild the fighting strength of the newly absolved Chapter.
* **Serkis Compliance (692.M38)** - The Ivaldi System was settled by humanity in the distant past and had remained isolated for millennia. Though bringing a new civilisation (who referred to themselves as the Serkis) into Imperial Compliance would bring the Imperium great renown, this formidable civilisation refused to bend the knee to the light of the Imperial Truth, and instead were prepared to fight to maintain their independence. The Imperium wanted Serkis's wealth and resources to harness for their own needs. So the securing of Serkis fell to the Brazen Lions, supported by select elements of the Astra Militarum and the forces of the Adeptus Mechanicus. Despite meticulous planning, the campaign did not begin well as substantial losses were inflicted upon the Imperial forces. The Brazen Lions recognized the dire circumstances of their situation and issued a request to Terra for reinforcements. Soon, Imperial reinforcements arrived in-system to augment the beleaguered Imperial forces. These forces included several additional Space Marines Chapters, such as the Blades of Dorn, Ice Dragons, Impalers, and Silverbacks Chapters. Despite his misgivings, the Brazen Lions Chapter Master grudgingly accepted these Chapters' assistance and immediately drew up plans for prosecuting the second offensive against the Serkis. Utilising the strength of their new reinforcements, the coalition of Angels of Death launched a successful second offensive against the Serkis that would soon see an Imperial victory.
* **The Titan Wars (920-925.M41)**

## Chapter Organisation

Unlike their genetic forebears, the Imperial Fists, the Blades of Dorn are strong adherents to the dictates of the *Codex Astartes*, however, they only nominally adhere to the *Codex* in terms of tactical and logistical division of their troops, with their insignia and command structure varying somewhat in structure and use. Most notably, the conventions of title and nomenclature used by the Chapter are of marked difference from the *Codex*. Feudal heraldic ranks that originated on the Chapter's homeworld of Ostiarius are traditionally appended to the nomenclature of the Blades of Dorn's command structure. The Chapter Master of the Blades of Dorn, for instance, is known as a Lictor. The Chapter's Lictor awards these titles in recognition of acts of courage and skill-at-arms performed by individual Battle-Brothers. Every rank is fully capable of making tactical decisions on the fly and is encouraged to act on their own initiative should those above them in rank, fall in battle.

###  Hierarchy & Rank Structure

####  Officer Ranks

* **Lictor** - Chapter Master equivalent.
* **Seneschal** - The Seneschal is the Lictor's second-in-command and field marshal, usually the Knight Marshal of the 1st Order.
* **Knight Marshal** Captain equivalent, charged with leading one of the Chapter's Orders (Companies).
* **Paralictor** - This rank is equivalent to the bygone rank of Lieutenant, which has been re-constituted from the days of the Great Crusade, following the introduction of the Primaris Space Marines into the Chapter's ranks.

####  Specialist Ranks

* **Grand Prelate** - Reclusiarch equivalent.
* **Viceroy** - An appointed position, serves as the Grand Prelate's second-in-command.
* **Vicar** - Chaplain equivalent.
* **Paravicar** - This rank is equivalent to a Chief Librarian. They are the leaders of an order's Signifiers, equal in rank to a Master of Blades.
* **Signifier** This rank is reserved for those battle-brothers who possess psychic abilities. (Equivalent to a Lexicanium, Epistolary or Codicier.)
* **Forge-Thane** - Master of the Forge.
* **Forge-Smith** - Techmarine equivalent.
* **Medicae Primus** - Chief Apothecary equivalent.
* **Medicae** - Apothecary.

####  Line Ranks

* **Knight Grand Cross** - Not a rank, but a senior grade of chivalry (the Chapter's highest honorific title) given to a Knight who has the knowledge, and achieved great accolades and monumental victories, above and beyond the call of duty. These Knights-Errant are entitled to wear Terminator Armour in battle.
* **Knight-Errant** - Veteran Marine equivalent.

* **Preceptor-Sergeant** - Sergeant equivalent rank, oversees the command of a squad (10 Astartes).
* **Preceptor-Brother** - Preceptor-Brothers are those who have passed all the Trials of Dorn and are recognised as full battle-brothers.
* **Armiger-Brother** - Armiger-Brothers or Armigers, are not yet full members of the Chapter, serving as the Chapter's Scout Marines.
* **Squire** - Squires are those Neophytes who have passed the initial Trials of Dorn, but have yet to undergo the necessary surgeries to become Astartes.

####  Non-Astartes Ranks

* **Esquire** - Senior ranking Chapter serfs that have faithfully served the Chapter for several decades of loyal, dedicated service.
* **Man-at-Arms** - Known also as an armsman, these stalwart retainers serve as the maintainers of a Preceptor-Brother's arms and equipment.
* **Page** - A young Chapter serf that serves as an attendant to a Preceptor-Brother.

###  Order of Battle

As a semi-*Codex* oriented Chapter, the Blades of Dorn are divided into ten Orders (Companies) comprised of 100 Space Marines each. Each Order is led by a veteran hero of the Chapter with the rank of Knight Marshal (Captain). In addition to their company command, these consummate warriors and leaders are also charged with a particular aspect of the Chapter's logistics.

Since the advent of the Primaris Space Marines being inducted into their ranks, the Blades of Dorn have effortlessly integrated these superior transhuman warriors into the various companies of the Chapter. Within some of the Chapter's companies, the Blades of Dorn have begun to incorporate the bygone rank of Paralictor (Lieutenant) - warriors who serve as sub-company leaders - with two assigned per Order (Company), to help act as the right hands of their Knight Marshals by providing flexibility and helping to direct their fellow battle-brothers in engagements.

When the situation calls for it, Battle Companies can divide into two Demi-Orders (Battle Demi-Companies) of fifty Astartes each, in order to spread their forces across multiple combat zones. These demi-companies are led by a Paralictor, who leads his brothers unflinchingly into battle, therefore taking the burden of command on the ground off the Knight Marshal's shoulders, so that he can concentrate on the overall flow and every-changing fluidity of the battle, and can adjust his tactics accordingly.

## Combat Doctrine

Like their genetic forebears, the Blades of Dorn are the epitome of *Codex Astartes* doctrine. All ranks are able to make tactical decisions and are encouraged to act on their own initiative, making this Chapter a truly flexible fighting force, able to adapt to almost any combat situation. The combat doctrines of this aggressive Chapter are those of the application of overwhelming force directed to where the foe is weakest. These shattering blows are used to utterly destroy enemy command cadres, and vital strategic support structures and wreak terrible slaughter on the pride of an enemy's forces, often turning the tide of an entire conflict with a single, well-placed, and savage attack. In accordance with the *Codex Astartes*, the Blades of Dorn combine all arms in flexible, balanced battle groups, each of which can present an opponent with a diversity of threats. The Blades of Dorn will then press their attack so swiftly that the foe is overwhelmed before they can react.

The Blades retain the traditional skills of the Imperial Fists in urban and siege warfare, although they are quite willing to engage and defeat the enemy in open battle in any type of environment. They use fortifications when on the defensive (which rarely occurs, as they are an aggressive Chapter), but only after all of the more aggressive options have been exhausted. Like the Imperial Fists, the Blades of Dorn's principal weakness is their reluctance to accept the possibility of defeat which sometimes blinds them to the risks inherent in their aggressive stratagems. The Blades will stubbornly hold their ground, refusing to withdraw from the field of battle, even when faced with annihilation by a numerically superior enemy force, despite being beneficial for them to do so.

## Chapter Beliefs

The Blades of Dorn are pious, zealous, and uncompromising Astartes who have a deep and abiding faith in the Emperor of Mankind and their Primarch Rogal Dorn. But faith is not the only thing that drives their actions - they are also burdened by overwhelming guilt for the actions of their former genetic forebears - the disgraced Crusaders of Dorn. When encountered, these stoic and taciturn Astartes seem aloof and standoffish, most likely due to the actions of their forebears, which aroused much suspicion amongst their fellow Adeptus Astartes Chapters. During the Years of Shame, many aspersions and recriminations were cast upon them without just cause, as the actions of their progenitors often overshadowed the loyal and faithful service of the Blades of Dorn. Though ultimately vindicated of their forebears' sins and granted the Emperor's forgiveness, they are sometimes still treated with much acrimony and suspicion by more zealous Chapters. This has caused the Blades of Dorn to tread lightly when working alongside other Space Marine Chapters but has also instilled within them an overwhelming drive to enact retribution against those who dare transgress against the God-Emperor and the laws of the Imperium.

## Chapter Gene-Seed

As a Successor Chapter of the Imperial Fists, the Blades of Dorn share their genetic legacy with their genetic forebears, especially after receiving their progenitor's own gene-stock following their redemption of the Years of Shame. Due to this direct link with their forebears, they have inherited many of the characteristics of their common Primarch Rogal Dorn. The Chapter's gene-seed is highly stable, though the Imperial Fists', and therefore the Blades' genome is lacking the Betcher's Gland that allows a Space Marine to spit corrosive acid and the Sus-an Membrane that allows him to enter a life-sustaining state of deep hibernation. The Blades of Dorn's gene-seed is remarkably stable and healthy, free of all other major mutations and Chaotic contamination.

###  Primarch's Curse: Only Honour in Death

Like their progenitors, the Blades of Dorn are more than willing to fight to the last, holding their ground with a siege-like mentality that sees them triumph or die in the attempt. This expression of duty can become exaggerated in members of the Chapter after long periods of combat, especially against foes such as Heretic Astartes. In these instances, these Battle-Brothers see only death; their comrades, the death of their world, and the death of their foes. A Blades Battle-Brother believes that the only righteous path lies in the expenditure of their own life for these purposes and he faces his death with a stoic heart and a single-mindedness that can only lead to the complete annihilation of everything and everyone he faces, eventually including even himself and those who fight beside him. When the Chapter's genetic curse manifests itself in an affected Battle-Brother, it comes on in three stages:

* **Stage 1 (No Retreat)**: As the odds mount so does the Battle-Brother's stubborn refusal to retreat, seeing only the glory and honour in defeating such overwhelming foes if even the barest glimmer of victory remains. Even if the doctrine and teaching of the *Codex* dictate retreat or flexible defence, the Battle-Brother will be loath to disengage until there is absolutely no choice, though often this can come too late.
* **Stage 2 (Suffer not Defeat)**: Defeat is a bitter pill to swallow for the Battle-Brother and he would rather die fighting than accept that he has failed. This can lead to reckless behaviour as he throws himself into the fray or takes on excessive odds to win when prudence and tactical reason would dictate he withdraws.
* **Stage 3 (Unto Death)**: The Battle-Brother has come to accept that perhaps only the cost of his own life will be enough to secure victory and is gladly willing to give it up. This can have dire consequences should the circumstances present him with a chance to martyr himself for the Emperor and bring ruin to the enemies of the Imperium. Should a Battle-Brother suffer mortal wounds, he gains a fatalistic desire to sell his life for the cause and will choose to expend his own life for a chance at victory or the safety of his brothers. This means he will fight on regardless of his wounds and continue to attack or place himself in the path of attacks even though the next blow could mean his end. He will also gladly accept suicidal ornear-suicidall tasks (such as disarming unstable warheads, leading a forlorn hope or holding a breach to buy time for his companions) without complaint.

## Notable Blades of Dorn

* **Lictor Fortis Dostriun** - Lictor Fortis Dostriun is the current Chapter Master of the Blades of Dorn Chapter.
* **Lictor Barathus Thornbur** - Predecessor of Fortis Dostriun, he was one of the longest-serving Chapter Masters of the Blades of Dorn Chapter, having served for over six-hundred years of faithful service to the Emperor.
* **Lictor Ivan Gardorian** - Chapter Master of the Blades of Dorn during the early 37th Millennium. When the Blades' progenitors were deemed renegades by the Inquisition, he voluntarily led his Chapter into the Eye of Terror on a Penitent Crusade, in order to take the fight to the Forces of Chaos and prove his Chapter's innocence. After nearly eight decades, the battered Chapter emerged from the Eye of Terror, and was subsequently tested for their purity of mind, body, and soul. Found unwanting, the Blades of Dorn were granted the Emperor's forgiveness and brought into the Imperial fold. Chapter Master Gardorian would continue to lead the Blades for another five centuries, overseeing the rebuilding of his shattered Chapter, and prosecuting the Imperium's wars against the heretic, xenos, and the daemon, until he was eventually killed during the 7th Black Crusade in 811.M37.
* **Lictor Saul Invictarius** - The first Chapter Master and patriarch of the Blades of Dorn, Saul Invictarius was the former First-Captain of the Crusaders of Dorn Chapter. When the 12th Founding occurred during the 35th Millennium, he was chosen for his zealous prosecution of his duties and strategic brilliance to lead the newly created Chapter. Though oftentimes he was regarded by Imperial authorities as a bitter and hubristic individual, he was an undoubtedly competent commander whose personal valour was second to none.
* **Knight Marshal Timon Reznor** - Seneschal Timon Reznor is the commander of the Blades' 1st Veteran Company and is the Chapter's *Master of Blades*. He serves as the Lictor's Equerry and right hand.
* **Knight Marshal Richard Greyson** - Richard Greyson is the current commander of the Blades' 2nd Battle Company.
* **Grand Prelate Lucan Valenburg** - Current Reclusiarch of the Blades of Dorn.
* **Viceroy Gaheris Huntinggard** -
* **Medicae Primus Gareth Palworth** - Current Chief Apothecary of the Chapter's Apothecarion.
* **Paravicar Asmodeus Grimgard** - Current Chief Librarian of the Chapter's Libarius.
* **Forge-Thane Erastil Blackstrong** - Current *Master of the Forge* of the Chapter's Armoury.
* **Prior Tristan Longstride** - Chapter Champion and personal bodyguard of Lictor Dostriun.

## Chapter Appearance

Many Imperial scholars have noted that the Blades of Dorn tend to utilise the most ancient patterns of power armour, weaponry, vehicles, and sacred relics. It is surmised that following their penitent crusade in the 38th Millennium, the Imperial Fists provided the battered Blades with the ancient VII Legion's most revered arms and equipment, in order to help bolster their severely depleted stocks of equipment and war material. The Blades of Dorn have continued to lovingly preserve their archaic arms and equipment, and have borne them down through the ages against the foes of their Primarch and the Emperor of Mankind.

###  Chapter Colours

####  Original Livery

The Blades of Dorn originally wore yellow and black coloured battle-plate. The chestguard, vambraces, gauntlets, belt, and groin guard were yellow in colour, dingy with the patina of millennia - the original yellow colour of the ancient Imperial Fists Legion. While the backpack, top of the helmet, shoulder pauldrons, cuisses (thigh armour), poleyns (knee guards), greaves (lower leg armour), and boots were black in colour, symbolising the Chapter's state of perpetual mourning for the loss of the Emperor and their Primarch Rogal Dorn. The shoulder pauldron trim, faceplate of the helmet, vents of the backpack, and details of the lower leg armour was gold in colour.

The Aquila or Imperialis on the chest guard was also gold in colour. The left shoulder pauldron proudly displayed the chapter's iconography, while the right shoulder pauldron bore the individual battle-brother's squad specialty markings (Fire Support, Close Support, Battleline, Veteran, or Command). The right poleyn displayed a white-coloured Roman numeral, which designated company assignment. It was not known how the Blades of Dorn designate squad numbers.

####  Post-Penitent Crusade Livery

Following the corruption of the Blades' progenitors and the completion of their Penitent Crusade, the Blades of Dorn re-painted the majority of the their battle-plate in sombre black. Though this symbolic colour still marked the loss they felt for the Emperor's mortal shell and the death of their Primarch, it also came to encapsulate the Blades' eternal shame that they were descended from a Chapter of oath-breakers. Parts of their power armour are still detailed in their original gold colours, including the faceplate, parts of the backpack, gorget (neck armour), shoulder pauldron trim, couters (elbow guards), and details around the poleyns (knee guards).

A golden coloured Aquila or Imperialis is worn on the plastron. The left shoulder pauldron proudly displays the chapter's iconography, while the right shoulder pauldron bears the individual battle-brother's squad specialty markings (Fire Support, Close Support, Battleline, Veteran, or Command). Alternatively, sometimes the squad specialty marking is indicated on the right vambrace. The right poleyn displays a white-coloured Roman numeral, which designated company number. Sometimes squad number is indicated by a small white coloured Roman numeral on the inset of the right shoulder pauldron or on the right vambrace.

###  Chapter Badge

The Blades of Dorn's Chapter badge consists of a golden gauntlet, reminiscent of their progenitor's Chapter iconography, holding aloft a sword which symbolising the Blades' neverending crusade to take the fight to the enemy. This central symbol is placed in front of a laurel, centered upon a field of black.

###  Allies

 Wardens of Orask |  | The Wardens of Orask are a stoic and proud Successor Chapter descended from the noble lineage of Roboute Guilliman. Following the Blades' inception during the Nova Terra Interregnum sometime during the 35th Millennium, the Wardens deployed en-masse to the troubled borders between the Segmentum Pacificus and the Segmentum Solar to help counteract the rapid erosion and contradiction of the Imperium's borders. The Wardens soon found themselves fighting alongside the newly created Blades of Dorn Chapter, which quickly garnered a reputation for being one of the most highly active Chapters during this conflict, deploying from warzone to warzone, fighting against secessionist forces as well as responding to various emergencies and adding their strength to multiple ongoing campaigns. Fighting alongside the Wardens, these two Chapters helped tip the balance of several conflicts in the Imperium's favour. Forming unbreakable bonds of friendship and brotherhood in the heat of battle, the Wardens were one of the few Chapters that continued to support the Blades of Dorn following the fall from grace, and eventual excommunication, of their progenitors - the Crusaders of Dorn. Despite the aspersions, suspicions, and outright hostility shown to the Blades, the Wardens stood by their cousin Chapter, and vehemently argued on their behalf, that they were both honorable and devoutly loyal, despite their progenitor's sins. Whenever called upon, the Wardens have eagerly answered the Blades' call, and have fought alongside this dedicated and stalwart Chapter several times down the millennia.

###  About the Blades of Dorn

"*I remember your Chapter Master Ivan Gardorian. He had the audacity to glare at me when I suggested that your Chapter was not as pure as they professed themselves, considering the dead he had left behind. I can see a little of him in how you glare at me now. I am glad that I now bear the mark of shame on my armour for having been proven wrong - you children are far greater than your forebears.*"
— Phoenix Commander Deus Krost of the Unbroken Spears
