Heralds of Coming Doom

History/Background and Beliefs
The Heralds Of Coming Doom are a 3rd Founding chapter of the Dark Angels lineage, however, there is much bad blood between these two chapters, because the Heralds were formed from the more radical elements of the Dark Angels Legion (originally), and they revere Lion El'Jonson, but blame him for the destruction of Caliban and the corruption of Luther and his followers, and as a result do not follow any of the traditions common to the Dark Angels and their successors, and they eschew calling themselves the "Unforgiven".

The Heralds have fought in many battles, including all of the Black Crusades, and the Tyranid Wars, and more recently the Orks and presently the Tau. The Heralds Of Coming Doom are a mainly fleet based chapter, but maintain a Fortress-Monastery somewhere between the Eye of Terror and the Rock, but its exact location is unknown to all apart from the Heralds themselves.

In the Heralds most famous and celebrated battle sometime in M33, the Heralds crushed a traitor Titan Legio on a Mechanicus forge world, during the fighting, the forge world's own resident Titan Legio was destroyed in the conflict (and later rebuilt), but their one Imperator Titan survived intact enough to be restored, so as the titan's Legio was destroyed, the Heralds claimed the servitude of the rebuilt Legio as payment.

This was presented with strong opposition from the Mechanicus (as the Heralds became the new unofficial masters of the Legio and therefore indirectly controlled it's Titans), but ultimately there was nothing they could do, so the Heralds took the Legio's servitude.

The Heralds restored the Imperator to its former glory and augmented it with psycho-active materials, so the crew could communicate psychically with the Heralds over great distances, these materials also had limited unintended side affects of increasing the Imperator's power. The Imperator was then christened Fatum ex Fustrix, it along with a small battle group of other Titans (mostly Reavers and Warhounds) stand vigil over the gates of the Heralds' Fortress Monastery on Bororus Prime as a sign of their contract with the Heralds and are at the command of the Doom Priest.

Doom Crusades
During times of grave need or when the Doom Priest has had great portents from the Doom Angel, the Chapter marches to many war-zones throughout the Imperium and commences massive war efforts known as Doom Crusades, holy wars fought in the Doom Angels name only to bring glory to the Chapter and Terra and to destroy all enemies of mankind. These Doom Crusades involve all the Doom Hosts of the Chapter supported by numerous Imperial Guard regiments and Titan battle-groups often working with several other Chapters, though the Heralds of Coming Doom are frequently the only Astartes involved. During these great events the Heralds will only use Bororusian Regiments and the Artrexus Titans without the support of non-vassal regiments, ships, other Astartes or Inquisitional troops if possible due to the great mysteries and secrets guarded and held by the Chapter. Other reasons include general distrust of other chapters and the Inquisition and the disregard of non-vassal regiments, though this is due to an increased level of risks involving Chapter secrets rather than a lack of competency. The Doom Crusades have been launched against all enemies of the Imperium over time from the repelling of Dark Eldar raids to the crushing and defeat of entire tendrils from Hive Fleets, including Behemoth. These Crusades bring the Chapter into even greater levels of scrutiny from the Inquisition and some chapters due to the massive levels of manpower and resources involved, as well as the scale of the campaigns. Though without a doubt these Crusades have been key to some of the Imperium's most important, if less well known victories (due to Inquisitional censorship) and this makes the Inquisition uneasy as this helps to display the Chapter's power if not to show it's scale and size though it arouses further doubts about the Chapter's faith, stability and threat assessment as these events indicates strengths in great excess of the Codex Standards. This has brought the Inquisition worries that they face when confronting the Black Templars due to the uncertainty regarding the Chapter's size and capability should they prove a threat and how likely they are to fall to Chaos due to their secrecy. These Crusades are always shrouded in mystery as the Chapter nearly always turns up unannounced with dozens of vassal regiments and Titan battle-groups and rarely do they share their true goals and objectives with other Imperial forces, remaining aloof and only work with other Imperial forces only when the success of their mission absolutely depends on co-operation with other forces outside their control. The Crusades themselves are also used to mask the Chapter's numbers from the rest of the Imperium and to confound the efforts of the Inquisition, this has furthered the distrust between the Heralds and the Inquisition. Geneseed sample dispatches to the Mechanicus are closely controlled so that the servants of the Machine-God never have enough of the Chapter's geneseed at one time to arouse enough interest or evidence to warrant an official full-scale Inquisitional investigation. Many Doom Crusades have been launched facing hundreds of the Imperium's foes, the most recent being the upstart Tau Empire, whose incursions and defences have withered under the constant assaults from the Heralds of Coming Doom and their vassals over the most recent centuries. The Crusades themselves can last from a few years to centuries long, depending on the strength and size of the enemies involved. The enemies crushed by the Doom Crusades have ranged from series of cultist uprisings to fully fledged Ork and Heretic and most recently, the dynamic Tau Empire. While these Crusades have earned the Chapter much favour and glory amongst the Emperor's followers, they have also made many enemies amongst the Inquisition and some of the more beleaguered Imperial forces which the Heralds refused to aid or co-operate with, only the Heralds' secrecy and their prowess on the battlefield along with the battles and glories won for the Imperium have foiled the Inquisition from making enough valid claims of heresy to declare the Chapter Excommunicate Traitoris.

Beliefs and Practises
The Heralds believe in making war according to the 4 Aspects Of Doom: Fire, Death, Terror and Vengeance, all Heralds are grouped into 4 cults, respective to each of the Aspects, then the mixture of the 4 cults are divided into the 10 Doom Hosts, or companies. The cult each Herald belongs to defines, which of the Aspects he specialises and beliefs in above the others, and there fore his wargear and fighting techniques.

The 4 Aspects are represented by a mythical being called The Doom Angel, who maybe an aspect of the Emperor as a great destructor, who has mastered all four Aspects and is a powerful psyker. It is these beliefs and organisation, similar to the pre-heresy Thousand Sons legion, which draw the attention of the Inquisition, who believe the Heralds might be heretics and mutants, but have never found any proof, and any Inquisitor, openly voices these claims at his peril, for the Heralds Of Coming Doom are amongst the most loyal of the Astartes, and also the most notorious.

Of all the Aspects and their respective cults, Death is the most dominant its members are comprised utterly of the Chapter's most hardened veterans and psykers, who are known as Seers. The Death cult forms the entire 1st Doom Host and wear suits of ancient Terminator armour. These Terminator squads are known as Death Bringers, as nothing but death follows in their wake on the battlefield and they are the epitome of the Death cult. Only members of the Death cult can earn the honour of joining the 1st Doom Host and wearing terminator armour, except for Doom Reapers who have dealt the Death cult a great honour, such as saving one of their leaders. Psykers of the Heralds, specialise in psychic powers, respective of the aspect they follow, Fire Seers use flames to protect their brothers and slay their foes. Death Seers harvest the life force of their enemies and use it weaken armies and temporarily strengthen the Heralds. Terror Seers conjure shadows and illusions to baffle their foes and allow their brothers sneak up on them, they also use psychic shrieks to smash enemy morale and minds. Vengeance Seers use their powers to cause the enemy's blood to boil, and harness their aspect to quicken their brothers' reflexes.

Each Aspect Cult is headed by a Great Seer, of whom the Great Death Seer is most highly ranking, the equal of any chief librarian. The Chapter Master, also known as the Doom Priest is the Chapter's most accomplished psyker who has mastered the martial and psychic arts of all four Aspects, he has a retinue of Doom Sayers (chaplains) who are spread throughout the Doom Hosts and respect all the Aspects equally, as does the Doom Priest, regardless of which cults, they may have originally joined and provide spiritual advice and welfare to the brothers. The Great Seers, upon their appointment are entombed in unique and heavily customised Dreadnoughts. The Doom Priest is always accompanied by a honour guard called the Doom Devils, an elite fighting force of Seers, who have forsaken the opportunity to become a great seer and have, or are in the process of mastering all 4 Aspects. It is from amongst these warriors that the next Doom Priest will be appointed though the Trials Of The Doom Angel, notably called this because the Heralds believe the Doom Angel will lend his strength to the most worthy Doom Devil to ascend to the rank of Doom Priest, which is why the Doom Priest(s) emulate the Doom Angel, to honour their victory and their heritage.

Earliest Days/Founding
Amongst the 3rd Founding Chapters created are the Heralds of Coming Doom, they were formed from the more radical members of the Dark Angels. A few years before the 3rd Founding, Interrogator Chaplain Jermiah Beridial was recently promoted to his new rank and was told of the Fallen and what had happened on Caliban. Disturbed by this, Jermiah went to sleep later that night after his training and meditation and seeing to the spiritual needs of his brothers. During his slumber he dreamed that the Emperor was speaking to him, introducing himself as the Doom Angel and how the other Astartes had yet to glimpse the way of warfare needed to defeat Chaos. The Emperor/Doom Angel told Jermiah to form his own Chapter in the name of Coming Doom and told him all about the 4 Aspects of Doom and how to wage war according to their creeds to defeat all enemies of humanity.

When he awoke, Jermiah was afire with righteous faith and then demanded the current Grand Master to allow him to take part in the coming 3rd Founding and create a new Chapter of the Dark Angels. The Grand Master agreed after much questioning, seeing the faith in the Chaplain's eyes. Jermiah selected a few marines and was given the geneseed, war ships and other supplies needed to found a Chapter. He started enlightening his new followers about the Emperor as the Doom Angel, an all destroying saviour of mankind and his creeds and his advice about the 4 Aspects of Doom.

The Cults and first Doom Hosts were created as recruiting into the Chapter began and so Jermiah, now Chapter Master of the newly christened Heralds of Coming Doom, took on the title of Doom Priest. as the Chapter organisation and librarium took form, Jermiah declared each Cult would be led by a Great Seer and that all his predecessors must be elite Seers who had refused their chance to don one of those mantles. As the Chapter grew in size and it's traditions and beliefs hammered out, it publicly denounced the crimes of Caliban, blaming the Lion and how his sons should fight for his redemption and for the Doom Angel, to the Grand Master of the Dark Angel's face. The Grand Master rejected all that Jermiah had said and started the centuries long hostility between the two Chapters. Jermiah, knowing his words and revelations were the truth, called the Grand Master a blind fool and that inability to see the truth would destroy the Imperium and left him to storm and stew in his own blind rage.

Soon afterwards Jermiah and his fledging Chapter left the Dark Angels at the Rock, however the Grand Master was so enraged he sent several Strike Cruisers and Battle Barges after the Doom Heralds. But the Heralds launched a psionic mine which killed all the navigators aboard the Dark Angel's fleet so they couldn't pursue them. A few weeks after this incident, the Grand Master saw how unwise it would be to continue persecuting the Doom Heralds, as it would led to an open war between the two Chapters, which the Imperium could ill afford and only stain the honour of the Dark Angels in the eyes of the other Chapters. This happened because the Grand Master realised no matter how unorthodox or insulting the path the path and beliefs the Doom Heralds had chosen, he would never be able to justify any overly hostile act towards them as the Chapter actually hadn't committed any heresy which could be proved major enough to earn their persecution. Therefore the Dark Angels and Heralds of Coming Doom would treat each other very carefully and wary from then on with hostility, but nothing violent or especially insulting.

Over the later centuries the Doom heralds grew in strength to their current numbers and colonised Bororus Prime and over the course of many decades, built their Fortress Monastery and Townships, mines and manufactories. Eventually they colonised the Bororus' Moons and converted them into archives of ancient knowledge, chapter secrets and ultimately orbital fortresses to protect their new homeworld below. They endured to keep the world's location from the rest of the Imperium and built an ancient, massive psychic device which could mask the presence of the planet from both conventional and warp sensors, this device has masked the planet completely since. During this time Jermiah received more visions from the Doom Angel, telling him how to advance his Chapter further and coaching him more about the Coming Doom and its 4 Aspects. Jermiah then relayed this information back to the Librarium and Chapter Teachers and thus the methods and tactics of the Chapter continued to grow and become more advanced. Amongst these visions were shown worlds that the Heralds had to crush to continue on their sacred path. These worlds varied from Ork territory to space and ground sacred to the Elder and on these worlds after a series of massive battles, the Chapter often found unique STCs which contained information on the construction of the unique wargear utilised by the Doom Heralds today. Believing the Doom Angel had gifted them with these STCs, for passing His trials and vanquishing many enemies of the Imperium, the Doom heralds refused to share their prizes with the Mechanicus, who at first remained ignorant of the new-found STCs. Eventually the Mechanicus heard rumours of the Heralds of Coming Doom using unique wargear as they became more notorious and demanded that they share any STCs the Chapter might have uncovered, but after failing of having found any evidence of heresy or crimes against the Imperium, the Mechanicus eventually relented as they have with other chapters such as the Blood Angels. This could also possibly be because of support for Heralds from the Space Wolves who believed that if the Heralds had indeed obtained STCs, they had the right to keep them for trophies. This hasn't been confirmed however though the two Chapters are indeed close as they both recognise the mutual benefit in such an alliance (though it is just as likely that they are allied because they both dislike the Dark Angels).

Tenets and Creeds
1. All shall obey the Doom Priest or his Great Seers during his absence, his Doom Devils speak with his voice, heed their words.

2. Repent not for yourself, but for the Primarch, He who doomed Caliban.

3. Respect all Aspects regardless of thou Cult.

4. Never retreat, never surrender only in the execution of the Foe's Doom will bring satisfaction.

5. Respect the spirits of your wargear, for though them will the Enemy meet their end.

6. Detest the fallen, but never let their presence deter you from your course, never place their Doom above your given command.

7. Revere the Seers and Doom Sayers for though their wisdom lies the true path of the Doom Angel's black light.

Litany of The Coming Doom

Detest the enemy and fill your heart with hatred, never retreat, never surrender, when all hope seems lost remember the creeds of the Doom Angel, His Aspects of War! Fire, Death, Terror, Vengeance these are the bloody blades with which we sow the Enemies' Coming Doom! Strike them down for eternity and damn them to destruction and to feel the dread gaze of the Doom Angel as he judges their worthless souls. For we are their Doom, we are His bloody talon to rend and tear the foul heart of the enemy from Mankind's heritage. We the Coming Knights, the Crusaders of Doom, the bane of corruption and foulness for we are the Angels of both Doom and Death and when the battlefield is filled with screams and curses, they, the Enemy shall know that at last their Doom is here and that the Doom Angel himself has sent us to throw them screaming into the pits of Hell, to utterly crush them of both body and will!

Organisation
The Heralds Of Coming Doom have unique organisation as they base it on their beliefs and don't follow the Codex Astartes. They are divided into the usual 10 companies, which are known as Doom Hosts, each Doom Host is led by a Doom Reaper (captains), who led command squads known as Doom Guards, who are headed by a Doom Champion. Each Doom Host is comprised of the following squads.

Fire Squads
These squads, believe crushing their foes at range, all vehicles of the chapter (with exception of Land Raiders, Rhinos, Land Speeders and Razorbacks as well as Dreadnoughts) belong to and are maintained by the Fire Cult and its squads. These squads form the core of the chapter and are the equivalent of Tactical Squads. These Squads form the elite of the Fire cult and are the equivalent of Sternguard Veterans. Fire Hammer Squads are the equivalent of Devastators.
 * Doom Fire Squads- Wargear: Power Armour, Boltguns, Frag and Krak grenades.
 * Doom Inferno Squads- Wargear: Power Armour, Doom Pattern Bolters, Frag and Krak grenades, Doom Kines.
 * Fire Hammer Squads- Wargear: Power Armour and Heavy Weapons such as Heavy Bolters and Lascannons.

Vengeance Squads
These squads, believe in killing their foes, with speed at close quarters and own the Chapter's Land Speeders. These squads are the equivalent of Assault Squads. These Squads form the elite of the Vengeance cult and are the equivalent of Vanguard Veterans.
 * Doom Styker Squads- Wargear: Power Armour, Jump packs, Vengeance Glaives, Melta Bombs and Bolt Pistols
 * Doom Fury Squads- Wargear: Power Armour, Doom packs, Vengeance Talons, Melta Bombs and Doom Kines.

Terror Squads
These squads, believe in using terror tactics and stealth, they are often used as assassins and melee line breakers. These Squads often use stealth to acquire their objectives and use terror tactics to crush their foes. These squads form the elite of the Terror cult and use similar tactics as the Terror Guard, but are often more upfront in battle.
 * Terror Guard Squads- Wargear: Power Armour, Terror Cloaks, storm bolters, Melta bombs, Horror Grenades and Chainswords.
 * Doom Ghost Squads- Wargear: Horror Armour, Terror Cloaks and Relic Blades.

Death Squads
The elite of the chapter, they believe in the Death Aspect above the others and the harvesting of life force. The younger members who have been accepted into the Cult who have yet to earn their Crux Terminatus, frequently serve with the Doom Scouts.
 * Death Bringer Squads- Wargear: Terminator Armour and a mixture of Power Weapons, Thunder Shields and Storm Bolters. Led by a Death Seer.
 * Death Squire Squads- Wargear: Squire Armour, Bolters and Frags and Doom Kines.

Doom Squads and Characters
These are Heralds Of Coming Doom, who have either no cult or have yet to join a cult. Initiates, who are still training to join the chapter as a fully fledged battle-brother and enlist to one of the cults The spiritual teachers of the chapter, similar to Chaplains, have forsaken any affinity with any of the Aspects as their office demands, they also function as the chapter's apothecaries. The leader of the Chapter, mastered all the Aspects and transcended the cults, and have no affinity to any Aspect or cult, as his office requires. Honour Guards of the Doom Herald, they have also mastered the 4 Aspects and the next Doom herald, will be chosen from amongst them. Drawn from all cults to act as a Doom Reaper's command squad.
 * Doom Scout Squads- Wargear: Scout Armour, Boltguns, Frag and Krak Grenades.
 * Doom Sayers- wargear: Power armour, Doom Mace, Storm Bolter and Rosarius
 * Doom Priest- Wargear: Doom Armour, Doom pack, Death Singer, Fire Bringer, Psychic Hood and Iron Halo and all Aspect powers.

 * Doom Guards- Wargear: Mixture of Bolt and Plasma weaponry and/or melee weapons according to which cult each member is drawn from.

Seers
Psykers of the Heralds Of Coming Doom. The leader of the Death Cult and Chief Seer. The leader of the Fire cult. The leader of the Vengeance cult. Leader of the Terror cult.

NOTE: All squads, with the exception of Death Bringers and Doom Guards are led by Sergeants as usual, though each Doom Host has a 1st Sergeant who is the Doom Reaper's second-in-command and successor.

NOTE: The 1st Squad of each Doom Host isn't a Command Squad. Command Squads have the Squad Designator of 0, for example 40 would the Command Squad of the 4th Doom Host.

Doom Host Strength- Explanation
Unlike many chapters the Heralds' forces are comprised of many different small, elite squads, accompanied by larger, more basic squads, whereas, most chapters use forces comprised of basic troops with 1 or 2 elite squads, usually of a larger size and smaller variety, than the elite squads fielded by the Heralds Of Coming Doom. It should be noted that the Fire Cult controls and maintains the heavy vehicles of the chapter, whilst the lander speeder variants are utilised by the Vengeance Cult and each Cult uses Dreadnoughts and drop pods.

It should be noted that the Heralds of Coming Doom's Doom Hosts often spend extended periods of time away from Bororus Prime (as they are mainly fleet based) anything from 5 years to 100 Years on massive crusades or surgical strikes to catty the Coming Doom to all the enemies of the Imperium. It is this and the the fact Bororus Prime is hidden from the rest of the Imperium that have made it impossible for the Inquisition to keep effective tabs on the Chapter. This has allowed them to flourish more than most chapters can reasonably expect and like chapters similar to the Black Templars have exceeded the supposed "limit" of around 1000 marines. This is to account for extended large scale crusades throughout the Imperium and because of their beliefs so they can more effectively serve the Doom Angel, however they are careful to hide their numbers so the other chapters or the Inquisition can't condemn them.

Ranking System
The Heralds of Coming Doom have a complex chain of command and promotion system based on an individual's skill and seniority, the Seers are more highly regarded and revered than psykers in other Chapters, but do not have total control for only non-psychics can become Doom Reapers. This is to balance the power of the Chapter between the psychic and non-psychic to maintain the right balance the Chapter believes in to enact the will of the Doom Angel with the most efficiency. The Apothicarium, Technicarium and the Reclusicarium all harbour similar positions to that in most Codex bound chapters, nut the Liberarium fulfils a higher position and purpose than those of other Chapters. This and the Great Seers and the title of Chief Librarian being held by the Great Death Seer, helps to maintain the equilibrium of the Chapter. This ensures that the Chapter has the psychic power and foresight to act as needed while retaining the faith, balance and manpower to carry these decisions and acts out.



Colours and Markings
Generally black with a dark purple quartering pattern with deep blue and red trim and Battle Brothers and Scouts lack helmet stripes. The left shoulder rim colour designates which company the battle-brother belongs to (white for 2nd, grey for 3rd, gold for 4th, orange for 5th, black for 6th, red for 7th, blue for 8th and purple for 9th, no rim for 10th as they are the scouts), the right shoulder (and helmet stripe if of "veteran" status) designates which cult the battle-brother is part of (red for fire, black for death, purple for terror and blue for vengeance). The main exception to this is the first company whose terminator armour uses darker colours to represent their allegiance to the Death Cult and 1st company (as they lack shoulder trim) and Seers sport grey helmets with laurels.

Heralds who belong to no single cult for example the Doom Priest (the Doom Priest's shoulder trim has no bearing on his Host-alliance as he controls all the Hosts through his Doom Reapers) or the Doom Devils have a dark green stripe (and other markings) on their helmets and armour to declare their neutrality towards the cults and to remember the loss of Caliban and the corruption of Luther. The right knee number designates Host-alliance and the left knee the company squad number.

Doom Sayers have dark green robes, helmet stripes, weapons, kneepads and shoulder trim. Their armour is un-quartered with right shoulder pad inset and arm purple and the left shoulder pad inset and arm blue, their backpacks sport dark red crowns and joints.

Sergeants and Veteran Sergeants are marked out by white helmet stripes, First Sergeants by grey helmet stripes and Doom Reapers by silver helmet stripes.

NOTE: both Veteran and First Sergeants also wear laurels to indicate their seniority as do Doom Reapers.



Combat Tactics
The Heralds believe in making war in accordance with the Aspects of Doom and as a result they use sub-tactics involving fire-fights, frontal and flanking assaults, armoured spearheads, stealth and sabotage and assassination in a series of larger scale tactics, in which each Aspect and Cult has it's own unique role to play. The Heralds of Coming doom have an unusual number of psykers amongst their ranks and make extensive use of psychic powers in their tactics as a result.

The Chapter are elite experts in mid to close range combat in almost any terrain and have earned a deadly reputation as flankers able to use the local terrain to deliver a surgical stab at the enemy's heart. The Herald are skilled at long range combat and fire fights as well as tank battles, courtesy of the Fire Cult and are unparalleled where sabotage and lighting Jump-Infantry thrusts are concerned. They are also adapt at orbital and space warfare, but have never specialised in it due their beliefs in the 4 Aspects of Doom, which do not particularly favour space warfare.

As mentioned above the Doom Heralds favour tactics involving all four Cults and Aspects, usually in the form of flanking manoeuvres and "shock and awe" tactics.

As a result their tactics often involve frontal assaults by Doom Ghosts and Death Bringers (if multi-Doom Host) and Fire Cultists, some Vengeance Cultists and armour, rolling towards enemy lines and pounding them to rubble, causing as much collateral damage as possible. Meanwhile Land Speeders, other Fire and Vengeance Cultists will attack from the flanks in a pincer movement crushing the enemy's flanks and causing untold damage. To finish it all off, Terror Guards, often accompanied by Pagnersaurs will infiltrate the enemy positions from behind, murdering key leaders and destroying strong points and vehicles such as artillery pieces with explosives, causing huge havoc and disorganisation of enemy forces, weakening them further. These stealth attacks and the effects of the Doom Ghosts on the front will severely damage enemy morale and significantly increase chances of enemy units routing, making them even easier to cut down.

The total effect is that the flanks fall with ease, allowing the Doom Heralds to crush their foe from behind, while the frontal assault pins them in place and draws their attention in addition in causing as much damage as possible and the stealth attacks make effective resistance nearly impossible. These tactics have always proved to be brutally effective and has won the Chapter the grudging respect of not only other chapters and the Inquisition, but that of Xenos factions like the Tau and Elder, who can appreciate the complexity and cunning of the tactics the Heralds of Coming Doom favour.

Frontal Assaults
The frontal assaults typically consists of half the attacking Doom Herald force, consisting of Fire Cultists tactically advancing under fire though any cover they can use, spraying enemy lines with bolter fire. Doom Inferno squads will typically use the Chapter's unique specialist bolter munitions to achieve certain objectives during the assualt such as suppressing enemy positions or to eliminate key armoured targets such as Chaos Terminators. Tanks such as Predators and Land Raiders will pound the enemy positions with a mixture of high explosives, heavy bolters, assualt canons and lascannons to cause as much damage to enemy positions as possible to keep their heads down and draw fire from the Infantry squads and cause serious collateral damage so their positions are easier to take. Vengeance Cultists may use jump packs or doom packs to quickly engage ranged infantry and negate some enemy fire and to cause additional havoc and to hold breaches or push the enemy back while the other Infantry advance with mechanised support. Doom Ghosts will often charge enemy lines under covering fire from Doom Herald Tanks and Fire Cult squads to draw enemy fire and crush morale to punch holes in enemy lines to cause as much damage as possible and even cause large routs using the psychic circuitry of their horror armour. Death Bringers serve a similar purpose to the Doom Ghosts and Fire Cult squads and frequently act as mobile heavy weapon squads, helping to crack open strong points, eliminate vehicles and armoured infantry and punching holes in enemy lines from mid range.

Flanking Attacks
The flanking attacks typically consists of a third of the attacking Doom Herald force, consisting of Fire Cultists who are mounted in Rhino and Razorback APCs and provide ranged support for the other elements of the flanking force. Doom Inferno squads will typically move at speed along with Doom Flames, strafing enemy positions with support fire to cover advancing Vengeance squads and suppress enemy squads and softening them. Land Speeders act as extremely mobile weapon platforms offering heavy fire to cover Infantry squads and crack open strong points. Tempest variants often attack from above softening up enemy Infantry and Armour using assualt canons, frag and krak missiles. Vengeance Cultists use jump packs or doom packs to quickly engage ranged infantry. This is to maintain the momentum and surprise of the flanking attack and to push the enemy back towards the centre and outwards towards to the frontal assualt, increasing pressure on the enemy and maximising the effectiveness of the pincer effect.

Stealth Attacks
The stealth attacks consist of remainder of the attacking Doom Herald force, consisting of Terror Guards, Scouts and Death Squires, they attack from the rear. Terror Guards use their skills to infiltrate enemy positions and eliminate key positions and vehicles and increase havoc and confusion by using their horror grenades to weaken enemy morale and cause them to hallucinate. Pagnersaurs often accompany the Terror Guards and infiltrate bunkers and other occupied positions slaughtering everything inside and murder key enemy leaders and terrify enemy troops. Scouts will also infiltrate enemy lines diverting enemy reinforcements and ambushing them as well as covering the Terror Guard if needed to and killing enemy leaders from range. The Scouts will also continue to feed intel to other squads in both the stealth attacks and the other assaults. Death Squires will help provide tactical support to the Scouts and Terror Guards and will often charge the enemy from behind to pincer strong points and artillery and Infantry formations, causing additional havoc and identifying key weaknesses in the enemy positions which were previously unknown and provide intel in hot spots too dangerous for the Scouts to enter.

Medals and Honours
Doom's Star- One of the highest medals a Herald of Coming Doom and achieve. It is awarded of great bravery and heroism during a crisis potentially threatening to the Chapter's survival or for slaying a great foe of the Imperium such as a Chaos Warlord. Very few Doom Heralds achieve this medal, though most Doom Devils in the Chapter have received this honour at some point during their career.

Fire's Cross- The highest honour available for marksmanship, awarded for supreme precision with a ranged weapon during battle, usually awarded to Doom Infernos and Death Bringers who choose to use Storm Bolters, etc. This medal tends to be awarded when one marine's or one squad's ranged support alone turn the tide of a major battle.

Death's Guise- Unique medal in the form of a helmet-mounted mask, awarded only to the Death Bringers for excellent skills of valour and warcraft, slaying hundreds of foes and holding the lines against all odds and showing extreme dedication in the Chapter's beliefs.

Terror's Voice- Medal awarded for crushing enemy morale or for stealth missions of a grand scale, turning the tide of battle and saving many lives as a result. This honour is usually awarded to Doom Ghosts and Terror Guards on an individual and squad based level.

Vengeance's Strike- Medal awarded for rapid response time and excellence in close quarter combat resulting in often climatic events which turn the tide of battle and slay hundreds of enemy Infantry and Tanks. This Honour is usually awarded to Doom Furies on both a individual and squad based level.

Dark Celestrial- Medal awarded to Brothers who have fought next to the Dark Angels or their fellow Successor Chapters. This honour is seen as many Brothers as a grim duty to wear as their is much bad blood between them and the Dark Angels. It is believed that bearing these in the presence of the Dark Angels will open up the rifts between the two Chapters even further.

Doom's Storm- Medal awarded to psychic Brothers for acts of bravery and servitude whose powers have saved the lives of many Battle-Brothers, or the act valorous act of defeating a Chaos Warlord or in extremely rare cases, a Greater Daemon. This is one of the recommended achievements needed to become a Great Seer.

NOTE: The Heralds of Coming Doom also make use of the normal Codex-approved honours and medals.

This squad also helped to train the scouts in marksmanship in times of need during the field when proper training facilities have been unavailable or lacking of the Astartes' needs. Current Roster: Garetal, Daggmiah, Dugrial, Fareth and veteran Sergeant Akios Vayna.


 * 42- The second squad of the fourth Doom Host. This squad is a Doom Ghost squad under Veteran Sergeant Kalikial Miahrus. They excel at melee combat and terror tactics and have won hundreds of battles by charging enemy lines and utilising the psychic auras of fear produced by their armour at the right times to crush enemy morale most effectively and thoroughly. They are regarded as one of the best squads of both the Terror Cult and the Chapter due to their patience and skills at stealth combined with their calculating mastery of close combat and innate understanding of how to use their armour psychic systems to achieve the most devastating effects. Their medals include but are not limited to: Doom's Star, Terror's Voice, and numerous Codex-approved awards. They have fought in the Scouring of Demos, the Purge of Gasus VI (Daemon World), the Fires of Arvar and the Hesian Uprising. It should also be noted that some of squad members were argued over by the Death and Terror Cults which Cult they should have joined as new Battle-Brothers as each side see their potential. The matter was finally settled when Zarkreus Safrion judged the young Brothers and declared them fit for the Terror Cult. Current Roster: Jakus, Gasis, Huromiah, Rexrius and Veteran Sergeant Kalikial Miahrus.


 * Doom Devils- The honour guard of the Doom Priest himself. These warriors are the very finest the Chapter has to offer, replete with the most ancient and powerful relics of the Chapter combined with their extremely formidable psychic power and unrivalled martial abilities. They are the most dreadful force to behold on the battlefield, combining all 4 Aspects and their relevant skills, tactics and powers into squad of super-elite Seers capable of destroying everything in their path from platoons of traitor Guardsmen to Greater Daemons. Medals include but aren't limited to: Doom's Star, Fire's Cross, Terror's Voice, Vengeance's Strike, Death's Guise, Dark Celestrial and numerous Codex-approved medals and honours for valour and honour and faith. They have fought in numerous campaigns including, They have fought in the Scouring of Demos, the Purge of Gasus VI (Daemon World), the Fires of Arvar and the Hesian Uprising, the Siege of Falzus II, the Smiting of Chaos and the Death of Legion and the Tau-Imperial Eastern Wars. It is from among the Doom Devils that the next Doom Priest will chosen though the Trials of The Doom Angel and the Doom Devil who completed the Trials with the most skill shall become the next Doom Preist. Therefore all Doom Devils must be trained in the ways of all the Cults and belong to no Cult and therefore avoid becoming too one-sided so that if the Doom Angel wills it, they will be able to lead the Chapter with the skill, leadership and neutrality required and the faith to tend to the spiritual well being of the Chapter if required to do so. As a result, many Brothers will go to a senior Doom Devil for advice if a Doom Sayer is unavailable. Current Roster: Arkiol, Rafius, Dareth, Jaymiah (and Doom Priest Zarkreus Safrion).

Genetic traits
Bororus Prime as a death world produces uniformly very fit and hardy people with surprising tenacity, who make both great Imperial Guard and Astartes recruits. These traits are carried on and compliment the traits granted by the gene-seed and surgeries used by the Chapter. This makes for strong and adaptable Space Marine recruits who can think on their feet and possess a strong common sense and intelligence. As a result the Heralds of Coming Doom are a slightly more independent chapter on a squad based level than most other chapters. This also has another more physical effect, Doom Herald Space Marines are typically slightly stronger and faster than most other Astartes. This likely due to a stable mutation in the human genome caused by the psychic presence of Bororus Prime.

The Herald's gene-seed itself sports several minor mutations. These include aesthetic features which are common to all Heralds such as semi-pale skin and black-brown hair and their eyes change colour to a silvery green. This due to high levels of magnesium developing in their hair and copper sulphate in the irises of their eyes and a slightly low levels of skin pigment. This is due to abnormal levels of hormones responsible for controlling the production of these substances in the body, caused by the mutations in the gene-seed.

Further mutations include increased production of hormones that increase synapse activity, this increases the potency of psykers. This combined with the psychic presence produced by Bororus Prime increases the numbers of psykers within the ranks of the Heralds of Coming Doom and their power. It is this abnormal amount of psykers (beside their beliefs and organisation) that bring the attentions of the Inquisition to the Heralds, which has sprung up various rumours around the Chapter. It is these rumours which have contributed to the notoriety of the Chapter which has added to the mysteries which shroud the Chapter.

As a result of these mutations the Chapter has an incredibly unique character as a result. To an outsider it could be easy to mistake all the brothers as identical due to their startling similarities in appearance in the majority of the Chapter. An outsider might also mistake the entire Chapter to be psychic due to their mysterious ways and the high levels of psykers can create the false appearance of there being far more psykers than there are to the untrained or uninformed eye. Other mutations include an extremely rare condition called Doom Rage, this is when the hormones controlling anger and frustration are produced in out of control levels. This causes the suffering marine to go into an uncontrollable battle rage and goes berserk, somewhat similar to the Black Rage and Red Thirst suffered by the Blood Angels, with the exception that the degeneration of the victim's mental state is gradual and that the victim does calm down after a while for brief periods, though anything can send them back into this blind rage.

This condition is extremely rare however and only affects one in 758 Doom Heralds, meaning there are only a few handful within the Chapter at anyone time. The Doom Rage causes the victim's metabolism to go into overdrive enhancing their speed and reflexes incredibly and increases the acidity of the acid produced by the Beltchers Gland. This allows the victim's spit to corrode and weaken almost any metal and cause massive damage to organic compounds found in living tissues. The victim's bones become stronger, but incredibly flexible and their flesh to become jelly like and supple, this allows it pucker and absorb bullets and other solid projectiles without damage and the marine's healing abilities increase drastically, allowing him to recover from just about any wound in a matter of seconds. Usually when it becomes clear that the victim won't recover and retain both his mind and body they are usually executed immediately before they get to this stage. However the symptoms can lie dormant for many years until the victim has become a mindless, flexible, bullet-immune hulk of what was a once-proud marine. The ultimate close quarter killing machine, but the Heralds executed victims like these or before when it becomes clear they won't recover because they belief these mutations are a desecration of the gifts given to them by the Doom Angel. Symptoms include increased sweating, abnormally coloured blood and decreased intelligence and sudden fits of anger and an increasing hunger for melee combat and sudden losses of discipline.

Auxiliaries
During chapter-level or multi-company level assaults and campaigns, the Heralds of Coming Doom summon their vassal allies to the fray. These vassal like allies have supported the Chapter numerous times over the centuries and they include ancient and honoured regiments and titans. Most of the Vassals come from Terrestes as the Heralds of Coming Doom saved the planet from the brink of destruction during their time of greatest need when the planet was assaulted by a traitor legio and it's supporting units, presumably to loot the planet of it's titan parts and supplies. These "Vassals" formed a contract of service and allegiance with Heralds of Coming Doom. The Chapter aids Terrestes when it is in need and in return it provides the Doom Heralds with several Guard units when they need large scale support. The Legio Artrexus also thanked the Chapter in this way and makes sure that there is always a battle-group of titans ready to aid the Doom Heralds. This was their way of repaying the Chapter for saving their Legio and recovering their Imperator Titan which was renamed the Fatum ex Fustrix.

Until they are called upon the Titans and Guard Regiments wait on Terrestes until they are called upon by the Chapter. Their fellow regiments and battle-groups wage war in other parts of the galaxy, knowing their home-world is safe, under the vigil guardianship of the Heralds of Coming Doom. The only exception to this is the Fatum ex Fustrix itself which is constantly guarding the gates of the Chapter's Fortress Monastery, unless it is called upon to wage war in the most dire of times. The Vassals are well equiped with the best wargear the Imperium has to offer its Guardsmen and the Mechanicus has to offer in the form of refits and modifications for the Legio. Many have raised eyebrows at these contracts, but the Inquisition cannot find anything invalid about the contracts considering other chapters also make use of the Guard and Mechanicus Titans and the Heralds have never been proved of heresy.
