The **Raven Guard** are a formerly Loyalist First Founding Space Marine Legion of Heretic Astartes who are wholly dedicated to the service of the Chaos God Tzeentch, the Lord of Change. Drawing on the demeanour of the techno-savages from which it initially recruited, the proto-XIXth Legion quickly demonstrated its skill at reconnaissance and target identification, and it ability to transition from inscrutable watchfulness to rapid attack in the blink of an eye. Its Legionaries waged war by infiltrating into position, studying their enemy and, when the time was right, striking from the least anticipated quarter and slaying the foe outright in a bloody, yet brief assault.

Corrupted while attempting to rebuild their legion after the Istvaan massacre, the Raven Guard have dedicated their lives and souls to Tzeentch, the God of Change. Flesh follows desire, as bone and armour is moulded into wings and claws. Even before their Fall the legion was able to strike from the darkness, to end battles before they even began. Now, guided by their powerful sorcerers, they are able to manipulate the fates of entire worlds.

## Legion History

### The Hidden Hand of the Emperor

The origin of the XIXth Legion begins on Terra during the Wars of Unification. The XIXth Legion were created as the Emperor's hidden hand - vengeful sentinels against recidivists and harrowers of those who would sooner flee than bend knee before the Master of Mankind. The similarities between the Raven Guard known to later histories of the Great Crusade and the XIXth Legion before its unification with Corax are clear, but much of the tale remains untold. It is known that the Emperor recruited the first Legionaries of the XIXth Legion from a number of Old Earth's regions, the majority drawn from the Xeric tribes of the Asiatic Dustfields. These savage yet technologically adept warrior people made constant war upon one another and against the neighbouring and much larger Yndonesic Block with relentless fury, battling ceaselessly for possession of scant natural resources. Once brought to heel by the Emperor and His Thunder Warriors, the tribes were forced to render up their firstborn sons to the Emperor's gene-forges, and upon their ascension to the nascent Legiones Astartes, these same sons were then used to ensure and enforce the continued Imperial Compliance of their fractious kin. The Xeric warriors proved well-suited to the Emperor's vision, though some observed their propensity for cruelty when ordered to attack as well as a disdainful attitude to those they considered weak. The culture of the Xeric people demanded that a vanquished enemy be watched over with a cold, all-seeing eye and any hint of recidivism crushed utterly lest the subjugated rise up in strength against the victor. The XIXth Legion inherited this mindset and when coupled with the heritage of the Legiones Astartes, it became one of its most distinctive characteristics.

Confronted with the coming of the Emperor, some of the enemies of Unification foolishly decided to stand and fight, to deny His manifest destiny. That was until the moment that the XIXth revealed themselves as the gun already raised to the target's temple without him ever seeing his would-be assassin's approach. In the face of such infiltration, most enemies capitulated. Never given to wanton cruelty, the Emperor's emissaries would avail the target of His impending doom and offer them the choice -- kneel or die. Most chose to serve but many refused, and so the XIXth Legion would be unleashed. Emerging from the shadows, they would attack without warning, their methods enabling them to engage with forces far more numerous than themselves. Bereft of leadership after a campaign of targeted assassination, most enemy armies fell apart in short order. When they did not, the XIXth Legion withdrew back into the shadows, but not in retreat. Rather, they attacked again from yet another quarter, bleeding their enemy dry and denying him any chance to counterattack, regroup or take the initiative.

### The Raven Lord

When the infant primarchs were scattered across the galaxy, most came to rest on worlds outside the bounds of the growing Imperium. The infant Corax, though, landed on a moon orbiting a planet that had recently been brought into compliance, yet there was no way for the Emperor to know that His lost son was already within His domain. The pale youth was found on Lycaeus, an airless mining moon orbiting the world of Kiavahr. Unfortunately, the Imperium's presence on the planet extended little beyond a handful of officials sent to ensure that the ruling Tech-Guild kept up the flow of equipment and weapons to nearby expeditions. Lycaeus was a penal colony, with the mines worked by criminals and dissidents opposed to Kiavahr's rulers. To be shipped up to Lycaeus was a life and death sentence combined, as the back-breaking labour, bad air and ever-present risk of cave-ins meant that life was ugly, brutish and short. Protests were quickly stamped upon by the guards, backed up with the ultimate sanction that if unrest ever became too vocal, the force-domes that enclosed the settlements would be deactivated and the unruly elements vented to open space.

The boy-primarch was found by the convicts, who recognised something exceptional about him. They hid the child from the guards and named him Corax, or "The Deliverer", so certain were they that he held the key to their salvation. This vision was shared by Corax, who from an early age had dreams of a vast, winged presence, a raven that guided him in times of trouble and spoke of a great destiny to protect mankind from its enemies. The first steps on this long road were to free the downtrodden population of Lycaeus from their brutal masters.

Despite the sickly surroundings, Corax matured rapidly to become a warrior of superhuman proportions. As he did so the convicts taught him all manner of techniques honed in Kiavahr's criminal underworld. Tactics such as sabotage, misdirection, intimidation and assassination would be vital in freeing them from the iron grip of their jailers, and Corax put all these skills and more to use. It was clear that they could not hope to match their overlords in open combat as the only weaponry they possessed were mining tools and machinery.

Corax clinically analysed his enemies' weaknesses and constructed an ingenious plan to bring about their demise. Through a subtle campaign of sabotage, Corax's followers steadily increased the pressure on the guards without ever drawing their wrath. The prisoner‟s mining skills were invaluable in this, first in gaining access to restricted areas, and later to outflank and surround their enemies. A series of "accidents" at the spaceport grounded much of Kiavahr's small fleet of mining shuttles which saw the guards‟ tours and shifts constantly extended as their replacements were trapped on the planet below. By the time Corax‟s revolution finally ignited, the warders were exhausted, disgruntled and easy prey. The greatest threat came from the towering black mountain from which their overlords ruled the moon, but it too was neutralised when the defenders found their control of the force domes had been subverted. Their attempts to vent the rioting prisoners into space only resulted in their fortress's blast doors grinding open and the force dome over the tower failing, flushing the guards themselves into space.

Incensed by the rebellion, the rulers of Kiavahr used their remaining shuttles to carry military forces up the gravity well. They fared no better than the guards before them, and were torn apart by Corax's grim-faced rebels, made all the more deadly by the weaponry taken from their former warders. Finally recognising the seriousness of the threat they faced, the leaders of the Tech-Guilds called for aid from the Imperium to put down the revolt. Without access to their moon's mineral resources the forges would rapidly fall cold, and the expeditions they supplied would soon falter.

The Imperial fleet arrived with creditable haste, heading directly for the turbulent moon, and after only a brief time the heads of the Tech-Guilds were curtly informed that the rebellion was at an end. When the Imperial flagship's landing craft touched down at Kiavahr's main spaceport, the rebel leader was brought out not in chains, but emerged proudly as a victor, alongside none other than the Emperor Himself. All assembled fell to their knees before the Master of Mankind, who proclaimed Corax as His son, and the man who would from that day onwards rule the Kiavahr system in His stead.

Cowed by this edict, and the legion of Astartes placed under Corax's command, the now subservient Tech-Guilds were given the task of providing arms and armour for his new 'Raven Guard'. Conditions for the miners were dramatically improved, and the moon of Lycaeus, now renamed '*Deliverance*' for Corax's achievements, became the legion's home. The forbidding black tower that had been the symbol of the Tech-Guild's power was reinforced and expanded to become the legion's fortress-monastery, and named the '*Ravenspire*'.

It has been suggested that the great raven in Corax's dreams was a manifestation of the Emperor reaching out to find him. Certainly, after father and son were reunited, Corax was rarely visited again by this mysterious presence. At Ullanor, Corax famously asked his father about this phenomenon, but, ever enigmatic, the Emperor simply smiled knowingly.

### The Great Crusade

"*Do not ask me to approach the battle meekly, to creep through the shadows, or to approach my foes quietly in the dark.
I am Rogal Dorn...
Imperial Fist...
Space Marine...
Emperor's Champion.*"
— Rogal Dorn, Primarh of the Legiones Astartes Imperial Fists, commenting on the Raven Guard's 'dishonourable' tactics

Even with the power of a legion of Astartes at his disposal, Corax continued to follow the precepts with which he had been brought up. He trained his commanders to observe the enemy, to strike at the place they were the most vulnerable, and to cripple their ability to strike back. While some primarchs used their forces as a bludgeon to bring worlds to compliance, the Raven Guard were the rapier of the Legiones Astartes.

Because of this, the Raven Guard rarely needed to operate in large groups. Instead they spread themselves out across dozens of expeditionary campaigns alongside many other legions. Indeed, it is said the reason Horus claimed so many victories was because he so readily used the Raven Guard to crack open the defences of worlds, which his own legion then followed up and took credit for liberating. In other cases, though, the cultural differences were just too great. Corax had forbidden the creation of a psychic Librarium within his legion, and considered that the way the Thousand Sons' embraced their burgeoning psychic potential bordered upon sorcery. He forbade the Raven Guard from fighting alongside them, and even spoke out against Magnus at his trial at Nikaea.

The other legion the Raven Guard went out of their way to avoid was the Imperial Fists. Rogal Dorn's disdain for tactics he deemed dishonourable was legendary, publicly decrying camouflage as being "*the colour of cowardice*". It is not clear if offense was intended, or if it was simply part of Dorn's brash insensitivity, but in the wake of such pronouncements the Raven Guard saw fit to remove themselves from Imperial Fist led campaigns.

Despite this, the list of worlds brought into the Imperium thanks to the Raven Guard's subtle application of military pressure continued apace. The fortress-system of Sangramor had withstood the might of the Imperium for decades, but within three months of arriving Corax's legion succeeded in isolating and crippling the system's rulers. With the planetary confederation fractured, the system‟s planets easily fell one after another and accepted the Emperor's rule. Their mastery of warfare was not restricted to battling human societies, either. When the Tanaburs sub-sector was threatened by a massive Ork uprising, the Raven Guard were able, through assassination and sabotage, to kill and discredit the most troublesome leaders without detection. The inevitable squabble for power stalled the Orks long enough for the Imperium to amass a large enough force to exterminate the xenos threat once and for all.

With the future of His Imperium seemingly assured, the Emperor withdrew to Terra, but before He did, He called His sons together at Nikaea. Evidently Corax was not alone in his concerns over Magnus, who stood accused of pushing beyond the boundaries of the psychic and into the forbidden realms of sorcery. One after another Leman Russ, Mortarion, Corax and even Dorn spoke out against their brother. The Raven Guard were not the only legion to have rejected librarians, and at Nikaea the nature of psychic ability itself was put on trial.

On the night before the Emperor rendered His judgement, Corax's dreams were again visited by a great bird. Rather than a comforting presence, it was troubling and elusive, an indistinct figure spied out of the corner of his eye. This disturbing omen presaged the Emperor's decision, which not only allowed the legions, with certain precautions, to continue the use of psychics, but went further and gave significant concessions to the Thousand Sons. Magnus was to be personally instructed by the Emperor in the subtle arts of the psychic, and could pass this knowledge on to his legion. In return, he and his marines would submit to the soul-binding process. By merging their essences with that of the Emperor, it was claimed, they would be shielded from the horrors and temptations of sorcery. This compromise did little to allay the fears of the most sceptical primarchs and led to bloodshed later, yet the Emperor seemed blind to the resentment it caused.

The primarchs returned to their legions to continue the Great Crusade. Under Horus' stewardship as Warmaster the list of worlds under the Emperor's dominion continued to grow, but without His presence a sense of malaise set in. This found form when the Warmaster himself was struck down by a sickness, and was unable to respond to the stories coming from the Eastern Fringe that Roboute Guilliman, Primarch of the Ultramarines, was about to secede from the Imperium. With Warmaster Horus indisposed, Rogal Dorn, in his role as the Emperor's Praetorian, assembled a fleet sufficient to bring the massive Ultramarine legion to heel. Along with many others, the Raven Guard was one of the legions summoned in their entirety to the Istvaan system.

### The Istvaan Betrayal

Guilliman's new 'Ultramar Segmentum' composed a sizable portion of the galactic east, and in their relative seclusion the Ultramarines had grown to vast proportions. To oppose them, fully half of the Legiones Astartes had been called to the task, with seven alone assembled to strike at Guilliman in his forward base of Istvaan V. Though disturbed that it could have come to brother fighting brother, and worse, doing so at the command of Rogal Dorn, Corax approached the task with his usual analytical nature. His offers to aid in the planning of the assault were brushed aside by Dorn, whose own skill at siege-breaking was legendary. Corax was dismissively informed that Dorn would lead the first wave of four legions to make planet-fall. They would weaken the Ultramarines, while the Raven Guard, World Eaters and Emperor's Children waited in orbit ready to strike the killing blow.

On the eve of the attack on Istvaan, as often happened at times of great turmoil, Corax's dreams were visited once again. As on Nikaea, the presence was elusive and did not reveal itself, but this time it spoke to him. Corax had been counselled by the raven countless times before, and so the warning that the legion faced a great disaster chilled him to the core. Corax's journal describes the dream:

"*I begged the figure to show itself, to explain what must be done to avert this terrible fate. From behind me I heard a scratching of claws in the shingle floor and turned to see not the raven that had guided me in my youth, but a thing far more like a vulture in aspect. The creature spouted bile, hissing that the Emperor had forsaken me, but that the lives of my men could be saved if I denounced my father and dedicated body and soul to the God of Change.*

*I confess to be so revolted and stunned that I could not speak. Perhaps mistaking my silence for consideration of its offer, the thing came closer and asked again if I would betray my father. “Never!” I shouted, and pushed it roughly away. It reared up into the air, plumage flushing pale blue, and fixed me with its evil, malevolent gaze. In a sibilant hiss it claimed that I would run like a coward on the battlefield of Istvaan, and consign my legion to utter ruin.*

*I picked a stone from the ground, and pouring into it all my revulsion and anger, cast it at the apparition. It caught the vulture in one of its hateful, blue-filmed eyes, provoking it into a fit of screeching curses. Its final threat of 'Nemo me impune lacessit', or 'No one attacks me with impunity', echoed in my ears long after I awoke.*"

Disturbed by the dream, Corax re-examined anything he could find about the coming battle to make sure that the prediction would not come to pass. At the final briefing Corax raised his concerns about the lack of visibility over the drop-site, but was mocked by Dorn for is caution. The Praetorian even portrayed it as cowardice in "*not wanting to take to the battlefield in an honest fight for once.*" Before this escalated further, Dorn threw down a sheaf of images of the planet below, taken, he said, the previous night during his unsuccessful visit to persuade Guilliman to surrender. None of his brother primarchs would return Corax's gaze as they filed out to start the attack on Istvaan V.

The four vanguard legions landed and reported good progress, and after what seemed like an eternity of waiting Dorn gave the command for the second wave to attack. Despite having scoured the images, Corax could find no fault in Dorn's plan. An orbital strike was part of the Raven Guard's favoured approach, so they took to their drop pods and ships with confidence, but even before they reached the ground it became clear that something was very wrong. They were targeted by ground fire far beyond that predicted, with jump pack equipped brethren cut to bloody shreds and even the lightning-fast drop pods meticulously blown apart by the Ultramarines' defences.

Corax assembled the survivors, only to be set upon not just by the Ultramarines, but also Dorn's vanguard legions gone turncoat. Stung by the prophesy that he would run like a coward, Corax assembled what remained of his legion for an attack against their betrayer, Rogal Dorn. Time and again the Raven Guard struck out of the darkness at Imperial Fist command positions, and yet Dorn himself was nowhere to be found. Certain that Dorn had finally been located, Corax appealed to the World Eaters and Emperor's Children for support, only to find them making a fighting retreat to their rescue landers. Cursing his brother primarchs for their weakness, Corax led the remnants of his legion in a forlorn, hopeless attack into the teeth of the Imperial Fist's guns. Heavily outnumbered, they sustained hideous losses, but while their primarch marched on, his men loyally followed to their doom. Finally, with only a score of his brothers left around him, Corax realised what his pride had done to the legion. He bitterly ordered the retreat, and the tattered remnants of the once-mighty Raven Guard faded back into the fog of war to join the evacuation.

With the Imperium alerted to Dorn's betrayal, the three broken legions evaded the traitors and paused, before returning to their respective homeworlds to rebuild. Corax silently fumed, not only at the traitors but at his allies for not supporting his final, catastrophic attack upon Rogal Dorn. He was certain that if they had followed his lead they could have killed the Great Betrayer and ended his treachery there and then. This resentment only deepened as the true scale of the war reached Deliverance.

### The Fall

Nothing was heard from the legion for some years after Istvaan. This in itself was not surprising as the entire Imperium was in the midst of a civil war, and the Raven Guard was ever a taciturn legion. When Imperial forces finally investigated rumours of dark goings on in the surrounding area of space, they found not just Deliverance, but also Kiavahr completely deserted. Even the force domes which retained the atmosphere around the Ravenspire were down, the great gates flung wide, and the fortress-monastery exposed to the vacuum of space. The account of what happened in that dark time has been drawn from what are thought to be Corax's own words, although their accuracy, and completeness, are matters of much conjecture.

Corax's journal tells that in his desire to rebuild his legion, he used the kind of accelerated zygote implantation techniques used in the earliest days of the Imperium. These methods had been abandoned for good reason, as the vast majority of the test subjects proved to be grossly deformed. Rather than dramatically increasing their numbers, it instead resulted in the depletion of their stocks of gene-seed. The lowest levels of the Ravenspire were filled with slavering monsters that became known as the '*Weregeld*', and their rhythmic, hypnotic hammering against their prison walls – like his shame – haunted Corax wherever he went.

At this low ebb, Corax's dreams were again taunted by the daemonic presence. It did not speak, and only looked down in silent judgement upon him with those cold, dead, vulture eyes. The next day, as Corax walked the corridors of the Ravenspire's vaults and happened to stare at one of the pitiful wretches penned within, he noticed the same vulture-like gaze staring mockingly back. Down the rows of Weregeld he searched, and inside each cell he found the same corruption of the soul looking back at him. Knowing what he had to do, Corax dismissed his assistants and went from cell to cell to systematically expunge his mistakes from existence. The rhythmic hammering of the creatures rose to a shuddering crescendo in the hour of the wolf, but by the dawn, it was at long last silenced.

The full story of what happened later – of how Corax was deposed and of his eventual fate – is far from clear. The bloody raids that brought the Imperium back to Deliverance were commanded not by the legion's primarch, but a shadowy figure known variously as the Clonelord, Progenitor or even the Manflayer. Extant records such as Corax's journal talk in glowing terms of an individual that had 'solved' the problem with the creation of new marines, although any reference of how this was achieved, or the identity of the Clonelord, had been carefully removed. As the Raven Guard's numbers rose, so did Corax's spirits. He took to training the new battle-brothers and even wrote of taking a force to help in the Siege of Terra. However, this was eventually replaced by disquiet at the nature of his new marines, in particular their increased level of uncontrolled psychic abilities, and the disturbing methods used to create them.

After this the journal entries end, although further information has been gleaned from writing on the wall of a specially constructed cell in what would have been the fortress-monastery's Apothecarion. The following was written in what was undoubtedly Corax's hand, and indeed in the primarch's own blood:

"*At first I thought I was still asleep; all I could hear was the same rhythmic thumping that has haunted my dreams for so long. Then I opened my eyes and realised I was truly in a waking nightmare. What I saw about me made the Weregeld look like beatific angels in comparison.*"

It appears that Corax had been drugged and imprisoned by the Clonelord as both a vital source of genetic material, and a cruel demonstration of what his legion was becoming. Corax went on to describe, in painful detail, how the Clonelord went about perverting his genetic legacy, and repeatedly chastised himself for a willful blindness of how his new brothers had been created. He told of the breeding of monsters, the forerunners of those who would go on to become all-too familiar opponents of the loyal legions. Through blasphemous rites their natural psychic potential was dramatically enhanced, turning the most skilled into sorcerers able to effortlessly manipulate the powers of the Warp. The majority were only able to use their latent powers to reconfigure their own bodies, and to a lesser extent their armour and weapons.

"*For these abominations, form follows desire. Fingers mould into talons. Nascent wings are extruded to lift them aloft. The failures, and those unable to control the changes they invite upon themselves, become little more than amorphous sacks of claws and spite.*"

The remainder of Corax's writings become ever-more incoherent as imprisonment, realisation and whatever experiments the Clonelord subjected him to took their toll. The final marking, drawn in blood, was a simple representation of a raven.

What ultimately became of Corax is unknown. When the Imperium came to investigate Deliverance the door of the prison cell was open and no body was ever found. At first it was thought that rapid decompression when the fortress-monastery's force dome failed had vented all of its occupants into space, but the rest of Deliverance, and Kiavahr were similarly deserted. The Imperium has recorded seventeen different instances of Raven Guard warlords and daemon-princes claiming to be Corax, but all have been discredited over the millennia. As the corrupter of one of the Emperor's loyal legions, much time and effort has gone into establishing the real identity and fate of the Clonelord, though after ten thousand years the trail has grown cold. No-one by that name has been associated with the Raven Guard since they fled Deliverance, although he could easily have taken another.

### Post-Heresy

In the wake of Dorn's Heresy, the corrupted Raven Guard fled their home moon of Deliverance and scattered to the whims of the Warp. While many of the Traitor Legions gravitated to the Eye of Terror to craft daemon worlds in their own images, the Raven Guard rejected such stagnation and have never been observed to stay in one place for long. Instead they endlessly move from planet to planet and from place to place, following the unfathomable whims Tzeentch, their dark God of Endless Change.

Anywhere touched by their foul presence is never the same again, as crops grow twisted and insanity and mutation run rampant. Investigations by the Adeptus Mechanicus, Thousand Sons and the Ecclesiarchy have each put forward theories to explain these phenomena, yet none have been able to effectively combat the corruption. Purging the area with fire and sowing the ground with salt seems to be the only way to prevent further loyal Imperial subjects from becoming corrupted.

For all the many changes that their corruption had wrought, they retained their primarch's ability to cripple an enemy before they even know they are fighting. In the centuries following their Fall, the Raven Guard carried out raids on disparate targets that left Imperial commanders bemused. While they had been bloody and militarily successful, the targets themselves were unusual, leaving other, much higher priority locations untouched. Initially it was attributed to the inevitable insanity associated with the worship of Chaos. In time, though, it became clear that these small, seemingly unconnected attacks were part of something far more sinister. For instance, a chain of events that started with a small raid on a promethium refinery in Pinosa Minor has been shown, with nudges from the Raven Guard, to have caused the loss of the entire Jhadra sub-sector a century later.

Because of this, confirmed attacks by the Raven Guard are analysed time and again by Imperial commanders for fear of where it might lead. Sometimes the very reinforcements and pursuit forces requested to bolster a region pays directly into their hands, as defences around the legion's true target are drawn away and left ripe for destruction. Such are the subtle weaving of fates the Raven Guard seek to engineer.

Of all the loyal legions of Astartes, the one with the best record of deflecting and thwarting the Raven Guard's wiles are the Thousand Sons. Their psychic divinations have enabled them to set traps for the Raven Guard, to counter their sorcerers, and banish their daemonic allies back to the warp. This rivalry has led to titanic battles between the two legions, although many of the worlds caught in these ætheric conflagrations have been left as uninhabitable husks.

## Legion Recruitment

Sometimes on their twisting path through the galaxy the Raven Guard choose to take captives rather than simply kill their victims. Among those destined to become slaves and sacrifices for their dark rituals, a few may be chosen to join the legion‟s ranks. Given their eldritch powers, it has been postulated that they are drawn to claim those with psychic potential. Be it an isolated agri-world settlement or the depths of the underhive, it seems that nowhere is beyond their grasp.

Whereas in most legions the creation and implantation of new marines is the responsibility of the Apothecarion, in the Raven Guard this grisly duty is solely the domain of their sorcerers. The process is an abomination of warp-craft which transcends any mere chirurgical procedure. It wipes away the conscience and morality of the victim and opens them up to the God of Change, and in doing so unlocks their psychic potential. This horrific process unleashes an uncanny ability to twist flesh and armour so that, as Corax put it, 'form follows desire', and in the most receptive individuals produces psychics amongst the most powerful in the galaxy.

## Legion Organisation

Raven Guard covens are led on the battlefield by their greatest warriors, although careful examination has shown that the true leaders are the sorcerers. As direct conduits to Tzeentch, the cabal of sorcerers guide their charges and direct them towards whatever incomprehensible mission they might be intent upon. The number of sorcerers in a coven varies depending upon its size and prestige, and the coven will sometimes split apart or merge with another seemingly on a whim.

According to Chief-Librarian Mieuren of the Thousand Sons, the success of a Raven Guard coven can be judged by its composition. Older, more established forces are composed largely of assault troops. Ones that have recently split off from a larger warband, or that have taken heavy losses, contain more of the younger, bolter armed marines that have yet to fully manifest their abilities to transform. According to Mieuren, covens rarely grow beyond a hundred marines in size – not including the attendant spawns and summoned daemonic entities - as their style of warfare achieves with lightning strikes what others would attempt with a massed assault. The number nine also seems to hold a fascination for them, with units composed of nine members being particularly favoured.

Because of the vital role played by the sorcerers to the continued existence of the coven, on only the most critical and sensitive occasions does a senior magus venture onto the battlefield. Usually lesser members of the cabal are sent in their stead, but such is the importance of even these individuals that they are inevitably surrounded by a cadre of brutal killers, summoned daemonic entities and the hideous results of their failed genetic experiments. Outside the cabal, marines are given respect based upon the extent to which they can transform their bodies. The monstrous Annihilators and the raven-winged Assault squads are held high above their younger bolter-armed brethren. Even the youngest initiates, though, look down in pity upon the amorphous spawn. These unfortunates have proved unequal of Tzeentch's gifts, and in doing so have paid the price with their sanity.

## Legion Combat Doctrine

The Raven Guard has retained the ability to attack without warning where the enemy is most vulnerable, and a favoured tactic is to strike under the cover of darkness, be it true night or a form of stygian gloom conjured up by their sorcerers. As befits their lightning-fast ambush tactics, the legion favours infantry over heavier vehicles. At the forefront of attacks are always their assault squads, who sweep in on sable wings before rending their victims apart with razor-sharp talons. In their wake come all manner of daemonic creatures spitting balefire and hate, and the grossly mutated spawns that can only be directed, if not controlled, by their sorcerer masters.

The youngest, least mutated marines are tasked with providing a strong gun-line to suppress the enemy. These brethren, whose abilities to transform their bodies and armour are yet to fully mature, fight instead with bolters and on occasion with heavier weaponry. An over-reliance on static firepower is rare though, and the role of laying down the heaviest ordnance is most often provided by the monstrous Annihilators. These abominations have willingly given themselves over to daemonic possession to enhance their natural abilities, and are able to transform their bodies and armour into a wide array of exotic weaponry. Be it a mob of Orks or an Imperial Land Raider, there is no target that these living tanks are unable to deal with.

How the Raven Guard are able to travel so rapidly between battle-zones without the aid of conventional transportation has never satisfactorily been explained by the Imperium. The most mundane theory has it that they have well-camouflaged transport vehicles away from the site of the battle. In recent centuries, though, credible reports have claimed seeing Raven Guard forces both appearing out of, and disappearing into, thin air. This could point to their ships possessing some advanced form of massed teleportation array, although the Raven Guard have only been observed to use the smallest types of capital ships. Given the power of their sorcerers, it is possible that this ability may be warp-derived, or, given their battles with the Farseers of the Ulthwé Craftworld, the Raven Guard may have forced access to the fabled Eldar Webway.

## Legion Gene-Seed

The shadowy Clonelord's perversion of the Raven Guard intentionally and irrevocably altered the legion's gene-seed; not only was Corax betrayed, his genetic legacy was murdered. In addition to the usual methods of implantation, chemotherapy and psycho-indoctrination, the sorcerers of the cabal utilise other, more esoteric methods to create new brethren.

Many of the original implants, such as the Mucranoid, Betcher's gland and often the Haemastamen are absent in the Raven Guard, while the intent of others have been changed radically, and completely new ones added. These changes, in particular the drastic alterations to the catalepsean node, are primarily focussed on enhancing psychic abilities.

In true prodigies this leads to the creation of sorcerers of incredible power, and in time can stimulate transformational abilities in others. While the remarkable ability of Raven Guard brethren to grow wings may be due in part to a hyper-stimulation of ossomodula and biscopea, nothing short of warp-craft would explain the way that ceramite and adamantium can be re-shaped at will into razor-sharp talons.

Despite the seemingly infinite variety into which the Raven Guard twist themselves, one constant remains. Just like their tragic, betrayed primarch, their skin is as white as snow and their hair and eyes are black as night. If this is an immutable part of Corax's genetic heritage or a bitter, taunting joke at his expense, only the God of Change knows for certain.

## Legion Beliefs

After leaving Deliverance, the Raven Guard fragmented to all intents and purposes, and has never fought as a legion since. They broke into warbands called 'covens' and spread out to every corner of the galaxy to further their own vision of how best to serve Tzeentch, the God of Change. These missions are frequently inexplicable, and on some occasions have led them into bloody conflict with rival covens. With a great deal of hindsight and infinite patience, dozens of seemingly minor nudges at history by the legion over the course of centuries have been shown to have catastrophic consequences. Imperial scholars and strategos have spent lifetimes trying to unravel the greater meaning behind the Raven Guard's actions, to as they say 'unweave the strands of fate'. The Adeptus Terra conducts periodic crackdowns upon this kind of research, saying, with some justification, that such cogitation is to invite only insanity, and that no good can come from trying to know the mind of a Chaos God.

## Notable Raven Guard

* **Corvus Corax** - Primarch of the Legiones Astartes Raven Guard, after the disastrous battle on Istvaan V, Corax and his shattered Legion limped back to their home world of Deliverance. Utilising forbidden techniques, such as accelerated zygote implantation, the Raven Guard's Apothecaries attempted to raise a new generation of Astartes. Though initially successful, soon however, the lowest levels of the Ravenspire were filled with mutated and grossly deformed creatures. Despondent, Corax was desperate to rebuild his shattered Legion, and so, struck a devil's bargain with the former Emperor's Children Apothecary known only as the 'Clonelord'. What exactly happened after this point is unclear, but extant records indicates that the Raven Lord was somehow subdued and imprisoned by the Clonelord. He then utilised the Primarch's genetic material and raised an entire new generation of Astartes, many of which possessed an increased level of uncontrolled psychic abilities. Corax's exact fate after this point is unclear, but years after Istvaan, both Deliverance and Kiavahr were found completely deserted.
* **Kayvaan Shrike** - Of all the Raven Guard covens at large in the galaxy, the most feared is undoubtedly that led by the Daemon Prince known as Kayvaan Shrike. He claims to have been born on Kiavahr, which the Adeptus Mechanicus have periodically tried to repopulate, and rose swiftly through the ranks to command the Subtle Blade Coven. His campaign to destabilize the Targus system, long a bulwark against the local Ork empires, reduced the million strong Imperial Army stationed there to a fraction of its former strength. Even the arrival of the Sixth Grand Company of the Iron Warriors could not halt this decline, who themselves lost more than half their number and three associated Ordinatii to the crippling Raven Guard raids. The loss of the Targus System, and the subsequent Ork rampage across the surrounding sub-sector crowned Shrike's ascension to daemon-princehood. His taunting proclamations that "*We are closer than you think, and our blades are sharp*" strikes fear into what little remains of the Imperial Army in the area. What deeper reason Tzeentch might have for unleashing this tide of greenskins, beyond fomenting chaos and unrest, is unclear, but the High Lords of Terra themselves watch for Shrike's next appearance with great apprehension.

### Reflex Shield Technology

During the time of the Great Crusade, the Raven Guard Legion fleet made use of a variant of void shield technology known as Reflex Shields that had been developed on the Forge World of Kiavahr, the planet which the Raven Guard's homeworld of Deliverance orbited. Reflex Shields acted as a form of cloaking device for Raven Guard warships, preventing them from being seen either by sensors or even the naked eye. A void shield worked by using the power of the Warp itself to displace incoming projectiles and high-energy attacks through gravitic manipulation. Reflex Shield technology altered the modulation of the warp-drive cores that powered a Raven Guard warship's standard Void Shields, calibrating them to a much higher tolerance and also directing them inwards, so that all of the matter and energy emitted by the vessel was redirected instead; all forms of electromagnetic radiation emitted by the Raven Guard's starships could be displaced, rendering them undetectable to almost all forms of scanning equipment.

The advantages of the Reflex Shield technology fitted well with the XIXth Legion's ethos of war, allowing Raven Guard starships to approach their targets unseen and strike swiftly and decisively before withdrawing. The low energy requirement for the use of the technology meant that such stealth could be maintained almost indefinitely. There was, however, a serious downside to the use of Reflex Shield technology. By employing its Void Shield generators for the projection of Reflex Shields, a Raven Guard vessel had no defence against physical attack and it took time to switch the generators from one state to the other, leaving a warship vulnerable for several minutes with neither its cloaking field nor its energy barriers fully operational.

To the auspex augurs and scanning arrays of an orbital base or starships throughout a star system, any starship activating Reflex Shield technology would seem to melt away into the stars. To the naked eye it would appear to shimmer, as the Reflex Shields engaged and reflected all visible light from the ship's surfaces, until eventually all such energy was dampened and the vessel was rendered effectively invisible to sensors and the naked eye alike. Another problem with Reflex Shield technology, one that Corax had unsuccessfully laboured to overcome for many years, was the relatively low amount of energy emissions it could cloak. A vessel's reactors could only be run at half power without generating too much energy to be displaced by the Reflex Shields. Thus, when operating under the cloak provided by the technology, a Raven Guard starship had to reduce its top speed and make do with decreased sensor capabilities.

## Legion Appearance

### Legion Colours

Prior to the Dornian Heresy, the Raven Guard Legion primarily wore black-coloured power armour, and made use of much more extensive iconography. Following the Heresy and their Fall, the Raven Guard adopted black and gold as their livery when they converted to the service of Tzeentch, but now they possess no fixed uniform. Some sorcerers and their attached warriors bear variations on these standard hues, such as dark grey and gold, whereas others add a third colour to reflect their own personal heraldry. Many Raven Guard Heretic Marines began wearing ornate crests on their helmets similar to the striped cloth Nemes crowns of the ancient Gyptian pharaohs of Old Terra.

### Legion Badge

The Raven Guard Legion badge consisted of a stylised, large white raven centered on a field of black. Following their corruption to the service of the Ruinous Powers, this symbol was altered slightly, symbolising their ever-changing bodies in the service to their patron god, Tzeentch.
