Great Crusade Chronology

Presented below is the **Great Crusade Chronology**, an exhaustive listing of all known campaigns that occurred during the nearly two standard-centuries-long Great Crusade that began in 798.M30 and ended with the outbreak of the galaxy-wide Almire Apostasy in the early years of the 31st Millennium.

At its height, the great expansion of the newborn Imperium of Man consisted of 4,287 primary Expedition Fleets engaged upon the business of enforcing Imperial Compliance and extending the Imperial aegis across the galaxy, as well as 60,000+ secondary deployment groups involved in regulating Compliance or Imperial occupations.

By no means is this list complete, to document such an event as the Great Crusade in full would take many lifetimes. Therefore, this is merely a rough guide to the chronological order of the events of the Great Crusade as a whole as they occurred, those events that concern a single legion are to be cataloged elsewhere.

## Chronology

Presented below is a chronological listing of the events of the Great Crusade. The following information was compiled by manifold and diverse hands at the order of Emperor and the Acting Council of Terra.

The reader should be aware that the dates listed in this chronological compilation are only approximations as Imperial records from this time are too fragmentary to be wholly reliable. As more information is uncovered in newly discovered Imperial records, it will be added to the chronology.

### Late 700s-800s.M30

* **M30.798 The Great Crusade Begins** - With the Sol System finally unified, the Emperor launches His interstellar quest to reunite the disparate worlds of Mankind and reforge them into one vast, galaxy-spanning empire known as the Imperium of Man. He intended this unity to usher in a new golden age for all humanity. The first Expeditionary Fleets carry the early legions away from the Cradle of Mankind, the warriors of the Vth Legion, the Crimson Swords, are amongst the first to break the Ort Cloud and venture into the unknown.
* **M30.801 - M30.804 The First Rangdan Xenocide** - The Rangdan Menace is first encountered, nearly wiping out the XVIth Legion in a deadly ambush. Only intervention by eight other legions, along with millions, if not billions of mortal soldiers, titans and Mechanicum constructs, led by the Emperor himself, are the Rangdan forced bac, though at great cost to the Imperium.
* **M30.802 Mk1 'Saturnine' Terminator Armour is developed** - The First working Tactical Dreadnought Armour suit, known as the Saturnine pattern, is completed, the first suits shipped to the IVth Legion, still rebuilding after the Unification Wars, though small numbers do get sent to other legions. They are not widely liked outside of the IVth, and as such never gain true traction.
* **M30.813 The Proximan Rebellion** - Nine years after the end of the Rangdan Xenocide, the Silver Wings travelled to the world of Proximan alongside the Emperor to accept the worlds surrender. During the ceremony, a vortex bomb is detonated, incapacitating the Emperor and wounding many of his Custodes guard. The Silver Wings honour guard are recorded to have held the tide against insurmountable odds as the Emperor was whisked to safety, buying him enough time to be evacuated even as they died to a man. In the wake of the Rebellion, the Emperor bestowed the gift of the Palatine Aquila upon the renamed Palatine Wings, forever marking them as carrying the Emperor's favour and helping to turn the XIVth from a legion of bragarts into humble servants of the Imperium.
* **M30.815 Almire Leoric is found by the Emperor** - Almire, Primarch of the XVIth Legion, is found on the world Knight of Hasninë. Almire offers no quarrel as the Emperor tells him of his lineage, kneeling before his Emperor and rising as the Primarch of the XIVth Legion, the Imperial Justicars.
* **M30.825 Camelous is found by the Emperor** - The Psyker Camelous of the XIXth Legion is found by the Emperor upon the world of Pax Primaris. The Legion, already kown as the Dragon Lords, are not renamed by their new Primarch, Camelous insisting that he would not undo the glory's of their comflicts before his arrival.
* **M30.833 The Mk2 Terminator Armour Prototypes are created** - Faced with numerous issues with the Mk1 Terminator Armour, the Mechanicum move to address them, beginning to create new designs to replace the Saturnine Armour. Though there were truly dozens if not more different prototypes created during this phase of the Tactical Dreadnought project, most simply refer to armours of this time as the MkII Terminator Armour, or Prototype Terminator Armour. Little else is known about these suits, none ever seeing combat within the Legions, the project soon being scrapped, all created designs offering negligable advantages over the current armour
* **M30.842 Galvarian is found by Almire** - Galvarian, Primarch of the XIth Legion, is found on the world of Æsce. He is not a ruler of the world, but a scientist, one deformed and mutilated by emperiments performed on him in the name of a cure for the plague that ravaged the world before the coming of the Imperium. Galvarian crusades alongside Almire for many years, the Primarch of the XVIth along with his own legion, now renamed the Ashen Crows, helping to tutor the newly found Primarch in the ways of war, something utterly alien to him before those days.
* **M30.850 Shaaa Hydrades is found by the Emperor** - Shaaa Hydrades, Primarch of the Dark Watchers, is found on the Dark Age space superstructure known only as "The Ring" at the edge of the Segmentum Solar and the Hydian Way. The Primarch is scarred and bitter, bearing numerous cybernetic implants to make up for the damage done to his body by his foster father. The Primarch Galvarian helps to craft new implants for his brother in his first years with the Imperium, though Shaaa quickly replaces these with his ones of his own design. After a period of crusading alongside the Emperor, Shaaa takes full command of the IVth Legion, renaming them Star Guardians.
* **M30.858 - M30.867 The Squat War/The War of Lost Cousins** - Known to the Imperium as The Squat Wars and the Squats as The War of Lost Cousins, Imperial Forces, led by Shaaa Hydrades, make first contact with the Khazadi Empire. War soon breaks out, drawing in multiple legions and millions of mortal and Mechanicum warriors, almost bringing an end to the Khazadi Empire. Such Destruction is only avoided when the recently rediscovered Sanguinius brokers a peace between the two empires, much to the disgust of Shaaa. The Khazadi Empire is absorbed into the Imperium, though like Mars retains a high level of autonomy, the Khazadi themselves taking the new name "Astra Khazadi".
* **M30.860 The First Mk3 Power Armour Suits are Created** - The first suits that would become the Mk3 Iron Armour are created by Shaaa Hydrades and his sons in the early years of the Squat Wars. These suits are little more than Mk2 Crusade Armour with additional plating welded to the front, battlefield needs making any more advanced alterations impossible for those fighting at the time.
* **M30.866 Sanguinius is found by the Emperor** - Sanguinius, Primarch of the IXth Legion, is found by the Emperor on the world of Baal. Soon after, a delegation from the Khazadi Empire arrives in system after being thrown off course in the warp, looking for allies in their war against the Imperium. Instead, listening to the Khazadi delegation, Sanguinius secures permission from the Emperor to broker peace, travelling to the Khazadi Empire. Hostiities end soon after, though the IVth holds the IXth, renamed the Blood Angels, and their lord in the highest contempt from that moment onwards.
* **M30.867 Mk3 Iron Armour is officially sanctioned by the Mechanicum** - The first new mark of Power Armour is sanctioned by the Mechanicum, designated as the Mk3 "Iron" armour. This armour is based off of the prototypes created by Shaaa Hydrades and his sons in the Squat Wars, and places extreme emphasis on frontal protection, the armours rear being lighter and the armour being far heavier as a result. The armour is soon shipped to all twenty of the Emperor's legions, the Star Guardians recieving more suits than any other, soon equipping the armour across their entire legion.
* **M30.869 Kodiak Ursidae is found by the Emperor** - Kodiak Ursidae, Primarch of the VIIth Legion, is found on the feral world of Skara. Unlike his legion, then known as the noble Knights Imperial, Kodiak is regarded as a savage, early attempts by the Emperor and his legion to mould him into the image of a knightly lord failing, the Legion soon taking on his bestial image, rising anew as the War Bears.
* **M30.871 Gauis Augustus Caligula is found by the Emperor** - Gaius Augustus Caligula is fond on the world of Dux, presented with his sons within the XIIIth Legion, soon renaming them for a final time to the Consuls Exemplar.
* **M30.872 - M30.876 The Second Rangdan Xenocide** - Taking place over seven decades after the First Rangdan Xenocide, the Second Rangdan Xenocide, often known simply as the Second War, was the largest of the three conflicts, over 75,000 Astartes perishing in the five years of punishing warfare. Though the scale of the Second Xenocide exceeded all others, the First is still considered the most deadly, drawing in and draining away far more of the fledgling Imperium's strength. Though the Second was deverstating, it never reached the level where the Imperium itself was truly on the brink of collapse, as some belived it to be during the First War. The Second War would see not only Gaius gain his first taste of combat within the Imperium, but would also see Camelous make a name for himself, hailed as the hero of the war, the title of Invctii being bestowed upon him.
* **M30.888 Vinicius & Euphranor Geminius are found by the Emperor** - Vinicius & Euphranor Geminius, also known as the Geminius Twins, are found by the Emperor on the gladiatorial world of Bion, already regarded as gods of the arena, a deadly duo without equal on the world. Soon they are placed in command of the XIIth Legion, renamed as the Brothers Encarmine.
* **M30.891 Abner Cassian is found by the Emperor** - Abner Cassian, the empty lord of the Xth Legion, is found by the Emperor on the blighted world of Alaunus. Emotionless and souless, Abner holds more in common with the Silent Sisterhood than his brother Primarchs, though does soon form a bond of sorts with Shaaa Hydrades. Taking to the ways of Imperial War with ease, Abner soon renamed the Xth as the Light Bringers, in honour of the captive and contained star that Abner himself wears upon his back, the tiny, dark age contained might of such a celestial phenominon bringing the Emperor's light across the gulf of space.
* **M30.894 Necalli is found by the Emperor** - Necalli is found by the Emperor of Mankind upon the world of Achcauhcapalli. Soon after, the IIIrd Legion is presented to Necalli, renamed as the Claws of Xipac.
* **M30.899 The 3rd Compliance of Nostramo** - The Imperial Justicars are tasked to ensure the "complete and continued compliance" of Nostramo, which was once again embroiled in open rebellion. Under the direction of Almire, the civilian population is completely displaced, arrested, killed, or drafted into service or labour by the legion and their accompanying Auxilia forces. The planet's cities and infrastructure are repopulated with loyal Imperial colonists who swiftly transform the planet into a prime producer of adamantium for the Imperium. In the wake of this compliance, a permanent Black Rod is established upon the world, alongside a full Battalion of XVIth Legion warriors, though this is later reduced to a Company after the world shows no sign of re-offending.

### 900s.M30

* **M30.900 Cataphractii Armour is developed**
* **M30.901 The *Herald of Destruction* is Completed** - The first Gloriana-class Battleship, the *Herald of Destruction*, finishes its construction at the Ring. Its baseline specifications are soon sent to Mars, the Emperor decreeing that each of the legions shall recieve such a vessel based upon their own personal combat styles. Some unique vessels, such as the Dragon Lords *Furiar Imperator* which predated the vessels creation and differed wildly from its plans, are redesignated as Gloriana-class shortly afterwards, the term becoming synonomous with whichever vessel served as the flagship of any given legion.
* **M30.902 Surmah Nyyrik is discovered by the Emperor** - Surmah Nyyrik is discovered upon the world of Verivaltas, a swampy but technologically advanced world on the cusp of moving beyond its own system. Surmah quickly takes to the Emperor's vision, renaming the XXth Legion the Hounds of Surmah, helping to further their already dark reputation as destroyers, even as he implements reforms to ensure diplomacy is attempted.
* **M30.907 Charon is found by the Emperor** - Charon is found by the Emperor upon the world of Acheron. Upon meeting the Emperor, Charon pledges himself to his causes, swearing the he will be the monster the Imperium requires, the Emperor's instrument of Terror to keep the masses in line. His Legion, the XVIIIth, are soon called to his side, renamed as the Wisps of Acheron.
* **M30.908 - M30.915 The Third Rangdan Xenocide** - The third and final war against the Rangdan Xenocide begins, conducted by the Venom Stalkers and the Wisps of Acheron. Though Charon was found shortly before the war began, the small nature of the threat led the Primarch to remain on his homeworld to oversee the restructiring of his legion and the recruitment of new warriors, leading the war to be fought mainly by Terran legionaries. Due to frictions between the Venom Stalkers and Wisps of Acheron over strategic and tactical ways to wage the compliance, losses quickly mount to unsustainable levels, forcing Charon to intervene. The Venom Stalkers soon face the Primarch's wrath, losing their commander not to the Rangdan, but to a son of the Emperor, the war ending soon afterwards. The Third Rangdan Xenocide may have been the smallest of the three wars, its consequences are still far reaching, having profound effects on the psyche and relations of both the IInd and the XVIIIth Legions.
* **M30.910 Caladrial Hex Arrives at Terra** - Unique amongst all the Primarch's, Caladrial Hex arrives at the edge of the Sol System onboard the now mobile world of Kastar. Though it is a small planet, the arrival of a new celestial body causes ripples in both the physical and political makeup on the system, the Mechanicum preparing to mobilise against this new threat and seize the technology upon its surface. These efforts are only halted when Caladrial is identified as a Primarch, the Emperor returning soon after to meet his newfound son, presenting him with a legion cast in his image, soon renamed as the Sirens of Kastar, in honour of the Siren Household of their new homeworld. Caladrial would remain on Terra for far longer than any of his brothers, learing the ways of the Imperium and ensuring his world would remain truly his, rather than being subsumbed by the Mechanicum.
* **M30.919 Khnum-Anhuret is found by the Emperor** - Khnum-Anhuret is found upon the world of Nephtis II, barely fifteen standard Terran years of age thanks to his gestation pod being trapped in the warp for far longer than any of his brothers. He is quickly taken to Terra where he learns the ways of war, meeting his brothers Caladrial Hex and Shaaa Hydrades and being placed in command of the Ist Legion, renamed in his honour as the Watchers of Akhet.
* **M30.921 Lorgar Aurelian is found by the Emperor** - Lorgar Aurelian, Primarch of the XIth Legion, is found by the Emperor on the world of Colchis.
* **M30.929 Jacinto Bolivar** **is found by the Emperor**
* **M30.930 The Gilded Vanguard engage in their first major campaign under Jacinto** - Together with the Ashen Crows and Watchers of Akhet the Gilded Vanguard lay siege to a forgeworld under heavy xenos occupation. Jacinto personally tracks a great Xenos beast across the world, slaying it at the height of the battle. It's bones are collected at the behest of Khnum, and wrought with adamantium into the giant, saw-toothed halberd Marrowbane by the artificers of the Ist Legion as a gift for Jacinto.
* **M30.930 - The Treaty of Kastar is finally Ratified** - Kastar finally leaves the Sol System after decades stuck in the beurocracy of Terra and Mars, its ruins and numerous artefacts examined and catalogued by the Mechanicum under the watchful eye of Caladrial himself. Much to the frustration of Calandrial Hex many of their technologies are removed including their ability to forge crude power armour, though the worlds Auxilia force is permitted to continue using and maintaining units still equipped with this armour. Caladrial does keep the ancient star map he discovered decades earlier a secret not only from the Mechanicum, but the Emperor himself, unwilling to lose such a potent relic, continuing to follow the path it laid before him as Kastar headed back out into the depths of space.
* **M30.943 The War of Murder** - The Palatine Wings first encounter the world of Murder, taking extremely heavy casualties against the insectoid foe, known only as the Megarachnids. Soon, a call for reinforcements is answered by Khnum and the Ist Legion, as well as a mysterious fleet of advanced humans claiming to oversee the sanctuary world, identifying themselves as the Interex.
* **M30.944 Bartosz and Khnum meet above the world of Murder** - Khnum conducts First Contact with the Interex, quickly finding that their leader is none other than a Primarch, known as Bartosz. The two quickly adjourn to the capital world of the Interex Empire, Xenobia, to discuss Bartosz's place in the Imperium, Khnum informing the Emperor of his new son.
* **M30.944-M30.945 - The Interexine War** - Shortly after Khnum departed from the foreign empire the Emperor arrived, speaking with Bartosz in private. The XIVth Legion, now under the command of Bartosz, launches an all out war against the Interex, making no attempts at parley and heeding no calls for mercy or surrender. It is said that Bartosz never spoke during the entire campaign, a hollow man as he wiped out his own people.
* **M30.945 The Battle of the Colossustructure** - The Imperial Justicars, Star Guardians, and Consuls Exemplar lead a strike against an AI superstructure known as the Endless Arkium, or colloquially "the Colossustructure" Mechanicum exploratory forces, accompanied by an expedition of the XVIth legion, mistakenly awaken the beast from it's slumber and are forced to call for heavy reinforcements from the Mechanicum, the Legio Titanicus, and multiple legions. Almire assumes command of the initial war efforts before the Emperor's own arrival as word reaches his fleet of the conflict's scale and enemy's power. The pair fight alongside each other throughout the remainder of the campaign, further solidifying their bond, and Almire's position as first amongst equals in the eyes his brothers.
* **M30.948 Lu Yueh zhi Zi is found by Shaaa Hydrades** - In the wake of the Battle of the Colossusstructure, Shaaa Hydrades diverts his depleted fleet to investigate the explosion of an ancient warp drive, finding the world of Jining and the world Emperor, Lu Yueh zhi Zi. Soon, the Emperor arrives to welcome Lu Yueh into the Imperium, presenting him with his own legion, Lu Yueh providing them a boast in moral and a firm leader that they lacked since the Third Rangdan Xenocide, renaming them the Blight Wardens.
* **M30.950 The Development of the Armageddon Class Planet Scourer begin**s - In the wake of the Battle of the Colossusstructure, both Almire and Shaaa see the need to a new breed of warship, designed for the sole purpose of bombarding an area of a hostile world with enough firepower to render any fortress obsolete. Taking que's from the mighty war machine known as the *Scorpion's Sting*, the pair travel to Mars, the construction of the vessels beginning in Mars' mighty Iron Ring.
* **M30.954 Artellion is found by the Ashen Crows** - Artellion, Primarch of the XVth Legion and last of the Primarch's to be reunited, is encountered by an Ashen Crows advanced scouting party, their Primarch, Galvarian, arriving shotly afterwards, sending word to the Emperor of Mankind and the XVth. Artellion was already the leader of an interstellar empire, one he had helped to forge from scratch, something no other son had done. Soon, the XVth were reunited with their sire, Artellion bestowing upon them the gift of a name, though none outside of the legion would no it until almost a year later. The Faceless Heralds met their lord, but it was the Silver Basilisks who continued from that moment forward.
* **M30.955 The Great Feast** - For the first time since their scattering, all of the Primarch's come together on the world of Bion, the Geminus Twins holding a mighty celebration upon their homeworld. Feasting, tournaments of skill amongst the assembled legionaries and a mighty hunt, all are had before the Primarch's once again scatter to the stars, none knowing that such an event would soon never be possible again.
* **M30.963 [REDACTED]** - Led by Shaaa Hydrades, a force consisting of the Claws of Xipac, Star Guardians, War Bears, Light Bringers and Ashen Crows descend upon [ALL FURTHER RECORDS REDACTED]
* **M30.964 Ashes of [REDACTED]** - The Imperial Justicars, under the direct orders of the Emperor of Mankind purge the world of [ALL FURTHER RECORDS REDACTED]
* **M30.970 The Sicaran Battle Tank begins development** - A joint project between Shaaa Hydrades, Galvarian, and overseen by Artellion, the three Primarch's begin the Sicaran project to begin replacing the venerable Predator main battle tank.
* **M30.980-M.30.985 The War of the Ròj** - Initially started by the World Shakers, the Ròj are encountered by the Imperium, the VIth taking initial heavy losses, spared from destruction by the intervention of the Watchers of Akhet and the Claws of Xipac. As the two new legions continue the campaign, the World Shakers retiring from the frontline to recover, the Ròj are revealed to be a tenacious and deadly foe, able to match the Imperium's advance blow for blow. It is not until [REDACTED] arrives to lend aid that progress is made, the Imperium finally exterminating the last of the xenos on the ancient world of Medusa.
* **M30.995** **The Fall of Thuyela -** A joint force from the Sirens of Kastar, Ashen Crows and Palatine Wings destroy the Aeldari Craftworld of Thuyela. The Land Raider Icarus is designed during this war, created initially from the wrecked hulls of standard Land Raiders
* **M30.999 Contact with the Malafic** - With in the Webway and amidst the Emperor's grand plan, adepts of the Emperor's own caste of Tech-Priests, the Adnector Concillium, unknowingly connect the Imperial webway with an ancient, disconnected branch. Within lay the twisted, sunken realm of the exiled Chaos God, Malal, unwittingly granting him freedom and access the the rest of the webway, that which had been denied to him for an aeon. Though the Custodes and the Emperor himself manage to stem the wrath of the starved and enfeebled god, holding back the tide of his daemons, it is not without cost and the project suffers a major setback.

### Early M31

* **M31.000 The Ullanor Crusade** - The War Bears encounter the largest Ork Empire thus far recorded by the Imperium. Soon, a mighty Crusade is formed, Almire Leoric assigned to lead it, with him are his own sons, Shaaa Hydrades and the IVth, Kodiak and the VIIth, alongside billions of Imperial Army soldiers, Mechanicum Constructs, Titans and Knights. Almire demonstrates his skills in combat and command once more, the attack utterly destroying the Ork Empire, Almire personally slaying the mighty Warboss, Overlord Urrlak Urruk.
* **M31.000 The Triumph of Ullanor** - In the wake of the victory, some recording the Ullanor Crusade as the high point of the Great Crusade, the Emperor of Mankind finally left the Great Crusade behind and returned to Terra to dedicate his time fully to his work on the Imperial Webway beneath the Imperial Palace, the breach into Malal's realm destabilising it enough to require his personal oversight. In His place to command the vast forces of the Great Crusade he left the Primarch Almire Leoric, hero of Ullanor, whom He raised to the newly-created rank of Imperial Warmaster. Almire received command authority over all of his fellow Primarchs and every Expeditionary Fleet of the Great Crusade. Alongside this promotion, Shaaa Hydrades was named Praetorian of Terra, him and his legion ordered to retire from the frontlines of the Great Crusade and return to the Throneworld to begin its fortification, which would take the form of the mighty Solar Guardian Array.
* **M31.001 The Council of Nikaea** - In the wake of a catastrophic incident during a joint compliance action between the Consuls Exemplar and the Dragon Lords which saw XIXth Legion psychic powers claim the lives of not only hundreds of legionaries but also countless civilian casualties, a mighty conclave was called by the Emperor himself. This conclave was held upon the world of Nikaea, which was intended to determine whether or not the use of psychic sorcery represented a boon or a grave danger to Mankind and the newborn Imperium of Man. Ultimately, the existence of psykers in the Imperium such as Astropaths and Navigators was allowed, but tightly restricted under centralised Imperial control, while the potent and unrestricted use of psychic abilities that was defined as sorcery was officially forbidden, as was the use of Librarians by the Space Marine Legions, despite arguments made against such a limitation. All existing Librarians were ordered to cease all use of their abilities and return to normal duties as line Astartes following the Council, the Chaplaincy setup to ensure the Edict of Nikaea was followed. Unbeknown to all, the Emperor also had a deeper reason than mere collateral possibilities. The incident in question had sent ripples through the warp, and destabilising portions of the already besieged Imperial Webway. It seemed apparent that if allowed to continue the Dragon Lords could, however unknowingly, forever doom the venture.
* **M31.002 Mk 4 'Maximus' Armour and Mk4 'Tartaros' Terminator Armour are created** - With new technological inovations being returned to the Mechanicum with each passing compliance action, the Mechanicum sets out to once again improve on the aging armours in use within the Space Marine Legions. In this, they succeed in creating both the Mk4 Maximus Power Armour, and the Mk4 Tartaros Terminator Armour, both lighter and more mobile than their predecessors, while retaining an equivalent level of protection. Soon, both suits are equipped across the legions, the Mk4 Power Armour and its sub-patterns soon becoming the standard across almost all of the Emperor's Legions.
* **M31.006 The Silencing** - Led by the Warmaster himself, a force comprised of his own legion and both the Wisps of Archeon and the Hounds of Surmah are sent to [ALL FURTHER RECORDS REDACTED].
* **M31.006** - After the events of the Silencing, Almire finally gave in to his council to rename his legion and further cement his newly appointed role. The Imperial Justicars are soon reborn as the Warmasters Justicars, none in doubt as to their primacy amongst the legions.
* **M31.008** **The Compliance of** **Milburga IX** -The Hounds of Surmah seek to bring the world of Milburga IX to compliance, but are caught entirely off guard as a Chaos cult enacts a ritual to transform the planet into a daemon world. With such irrefutable proof of his Father's lies, and the blood of his brother just two years prior who simply sought to speak the truth on his hands, Surmah's will and mind are shattered. The Legion falls from their path and begin to seek answers to the horrors they were forced to witness.
* **M31.010 Mk5 Phalanx Armour is created**- Just as the Mk4 had replaced the Mk2 Power Armour, the Mk5 project all but replaced the ageing Mk3 suits throughout the legions, once again spearheaded by Shaaa Hydrades. The armour, using Mk4 armour as a base, is superior to the old Mk3 in every way.
* **M31.015 Mk 6 'Rogue' Armour is created** - Alongside the Mk5 armour, the Mk6 pattern is developed after a request from Caladrial Hex for a suit of armour better suited for piloting the speeder craft the legion made heavy use of, as well as an answer to the need for a stealthy power armour. Containing enhanced sensors in the beak like helmet, as well as enhanced sound dampening servos, the Mk6 armour was weaker than even the Mk2 suit in terms of raw defencive power, but made up for it in a multitude of other ways, having the most advanced systems to date. The armour is never intended to be rolled out as standard across the legions, the Vth Legion taking many suits into their armouries as the trial period for such a radically different suit begins.
* **M31.022 The First Ten Armageddon Class Planet Scourers are Completed -** The first ten Armageddon Class Planet Scourers are completed, five being sent to the Imperial Justicars, while the remaining five are kept by Shaaa Hydrades for use within the Solar Defence Fleet. The vessels are based around an Emperor-class battleship, but lack almost any form of directed weaponry, as well as being flown by a skeleton crew, almost their entire super-structure being taken up by the mighty plasma scourers that give the vessel their name. The XVIth immediately put the vessel to good use, showing their worth in dozens of campaigns. The Mechanicum begins plans to create more of these vessels, though the plans remain held only on Mars.
* **M31.040 Mk5 'Indomitus' Terminator Armour is created** - Designed as a cheaper alternative to the more difficult to manufacture though superior Cataphractii and Tartaros patterns, the Indomitus pattern of Terminator Armour lacked some of the most sophisticated technologies used in those suits, but was far easier to produce and maintain in the field as a result.
* **M31.054 The Council of Vision** - Called together by an increasingly unstable Galvarian, numerous Primarch's including Gaius Augustus Caligula are called to witness a 'contest' of sorts, asked to produce their greatest warriors to face off against a helmed giant wearing the colours of the XIth. When the giant wins each bout with seeming ease, Galvarian reveals that beneath the armour is no mere Astartes, showing instead his newest creation; the Abaze. A combination of xenos, astartes, and even Primarch DNA, Galvarian believed that such a warrior was the future of the Imperium, expecting all assembled before his to wholeheartedly agree. Instead, cries of treason sounded out, Galvarian only narrowly escaping being taken into custody by those present by the ministering words of Gaius, the Primarch of the Consul Exemplar publically ensuring his brothers that Galvarian would return to Terra of his own volition, but to the broken minded Galvarian, instead whispered of the Warmaster's certain acceptance of such a new weapon. Unsure of what the correct course to take was, Galvarian was allowed to leave the Council of Vision alone, his mental deficiencies becoming exponentially worse in the following weeks.
* **M31.055 The Night of Blood** - The Light Bringers, Consuls Exemplar, Silver Basilisks and Warmasters Justicars unexpectedly turn on those within their own legions who would never follow their sires into betrayal, slaughtering many of them in their sleep, as they trained, or in other places when their guard was at its lowest. Tens of thousands are slaughtered in those first few hours of betrayal, only a handful escaping to bring word of what was on the horizon to the Imperium. When history looked back at the events of the Great Crusade, all point to this singular event as not only the end of the Great Crusade, but the beginning of a far darker period of history within the galaxy, the Almire Apostasy.
