Great Crusade Chronology - 900s.M30: ca. 900.M30 Establishment of the Temple of the Saviour Emperor - A highly decorated Imperial Army officer takes the name "Fatidicus," meaning "prophet," and secretly establishes the Temple of the Saviour Emperor on Terra which worships the Emperor of Mankind as the God of Humanity in violation of the atheistic doctrines of the Imperial Truth. Via the Imperial Army, and with the aid of other cults of Emperor-worship such as the Lectitio Divinitatus, his teachings will eventually spread across the entire newborn Imperium of Man.ca. 900s.M30 Assault on Dulan - As the Space Marine Legions pushed back the frontiers of the Imperium, each Primarch strove to excel in the eyes of the Emperor and none more so than Leman Russ, Primarch of the Space Wolves. Only Horus and Lion El'Jonson could claim more victories than Russ and this was a constant frustration for him. It was on the world of Dulan where the Space Wolves were fighting alongside the Dark Angels that matters came to a head. The Tyrant of Duran had personally insulted the Emperor, sacrificing thousands of Imperial envoys to his patron daemon, and both Russ and Jonson desired the honour of slaying this Heretic. The Tyrant Durath insulted Russ, causing him to demand the right to lead the attack on the fortress. Johnson ignored him and led his own carefully-planned attack instead, killing the Tyrant personally. After the battle Russ confronted and attacked Johnson, and the two duelled for a solar day and a night. Russ eventually stopped attacking, seeing the humour of the situation, at which point Johnson knocked him unconscious. Now The Lion considered his honour to be satisfied. The prostrate Russ was carried from the fortress by his men and, when he regained consciousness, the Dark Angels had already departed to fight in the Alisore Campaign. Russ swore he would avenge the stain on his honour and, to this day, whenever the Space Wolves and Dark Angels meet, one of their number is called upon to refight the duel of their Primarchs in order that honour may be satisfied.ca. 900s.M30 Compliance of Tarsis This was an Imperial Compliance action carried out by the Ultramarines Legion upon the world of Tarsis against unknown assailants. During the assault, the Primarch Roboute Guilliman was attacked by a mysterious assailant, but was saved by a native soldier of this world. In a supreme display of humility, Guilliman bent his knee before the soldier and vowed a warrior's oath that should his world ever need aid, then the Ultramarines would answer the call. A temple within the capital city of Erebus displayed the Tarsis Frescoe, a mosaic of enormous proportions painted by an unknown artist that covered the walls, ceiling and even the floor, treating the entire chamber like a canvas. This fresco displayed the events that had occurred during the Great Crusade. In gratitude to Guilliman and the Ultramarines, the planet renamed itself Tarsis Ultra in honour of its saviours.ca. 900s.M30 Shi'Hu'Gal Purge - The Night Lords, supported by the Titan Legions Legio Vulcanum I ("Dark Fire") and Legio Vulcanum II, carried out the infamous xenocidal purge of the Shi'Hu'Gal Dominion during the Great Crusade; this was a campaign of such fury and viciousness it remains a legend of this bygone era, even after the far greater death and destruction caused by Horus' betrayal of the Emperor.ca. 900s.M30 Compliance of Tethonus - The Luna Wolves Legion fought against an unidentified xenos-adversary whose identity is not recorded in existing Imperial records while bringing the world of Tethonus into Imperial Compliance. This Compliance action was a long siege of the xenos fortress-states on Tethonus. Horus had tasked the masters of the Forge World of Diamat to create continental Ordinatii siege machines; vast artillery pieces that could devastate the most powerful fortifications. But the war machines took much longer for the forge masters to complete than planned. By the time they were finished, the campaign on Tethonus had been over for over a standard year and a half, and Horus had moved on to other conquests. So the weapons were put into a depot on Diamat against the day when he would come to claim them. Fifty standard years later, Horus would reveal his perfidy at Istvaan III, and would send raiding forces to claim these siege engines for later use in his attempt to overthrow the Emperor of Mankind.ca. 900s.M30 Assault on Dahinta - On the world of Dahinta, the Luna Wolves Legion fought against a race of self-aware machines called the Overseers, who were led by the artificial general intelligence known as the Archdroid. One of the Emperor's longest-standing commands was that no sentient machines could be allowed to exist, for they had nearly caused the extinction of Mankind when they had rebelled against their Human overseers during the Dark Age of Technology. Despite heavy casualties amongst the Astartes, the thinking machines were wiped from the face of Dahinta by the savagery of the Luna Wolves. Only after the campaign had ended was the full truth learned: the Overseers had been created by a vanished offshoot of humanity that had settled Dahinta, perhaps during the Age of Technology. The Overseers had cared for their lost masters' crumbling cities long after they had become extinct or left their homeworld behind.ca. 900s.M30 Compliance of Five-Twenty-Nine - This was an Imperial Compliance action carried out by the Alpha Legion against an adversary of unknown origin upon the world designated Five-Twenty-Nine.ca. 900s.M30 Compliance of Fernius Worlds - This was an Imperial Compliance action carried out jointly by the Alpha Legion and an Imperial Army sentry force comprised of the Geno Seven-Sixty Spartocid. The Seven-Sixty were a well-drilled, gene-engineered regiment and did not spook easily. They played an instrumental role during the Compliance of the Ferinus Worlds.ca. 900s.M30 Compliance of Thorium Abominiplex - This was an Imperial Compliance action that was carried out jointly by both the Alpha Legion and Death Guard Legion against an unrecorded adversary.ca. 900s.M30 Xenocide of Kamenka Troika - This was a campaign of extermination waged in the middle years of the Great Crusade against the barbaric Orks of the Kamenka Troika System. The Emperor had issued the writs of war, commanding the Thousand Sons, the Legio Astorum Titan Legion and a Lifehost of PanPac Eugenians of the Imperial Army to drive that savage race of xenos from the three satellite planets of Kamenka Ulizarna, a world claimed by the Mechanicum of Mars. The savagery of that war, the slaughter and relentless, grinding attrition had left tens of thousands of dead in its wake. The Imperial forces proved victorious after two standard years of fighting and earned a score of honours for their war banners. Victory had been won, but the cost had been high. The Thousand Sons sustained severe losses of 873 battle-brothers of the 5th Fellowship, effectively wiping the 5th out as a functioning unit. This forced Magnus the Red to reduce his Legion from ten Fellowships to the Pesedjet, the nine classic Fellowships of Prosperine antiquity.902.M30 Subjugation of Kaldorax Aleph - The Iron Warriors 118th and 3rd Grand Battalions undertake the forced subjugation of Kaldorax Aleph, but sustain a high blood price to achieve victory, suffering nearly 65% casualties. However, the Iron Warriors succeed in absolutely crushing the non-Compliant forces of the intransigent world.903.M30 The Defence of Tranquillity - The Emperor's Children Legion defend a series of ancient crystalline gates claimed by the Imperium in the Dalinite Nebula against an unknown xenos fleet, which emerges from these gates, making rapid Warp translations between them. The III Legion eventually overpowers the xenos and drives them back whence they came.903.M30 Compliance of 47-10 (Khur) - The Word Bearers successfully bring the world of Khur into Imperial Compliance approximately a Terran century before the events of the Istvaan III Atrocity at the outset of the Horus Heresy. The beautiful planetary capital city of Khur, known as Monarchia, called the "Perfect City" by the Word Bearers, was later built by the people of Khur at the direction and exhortation of the Word Bearers to demonstrate their faith and devotion to the God-Emperor.Early 900s.M30 Golgothan Slaughter, Siege of Sarum - The first known target to suffer the wrath of the World Eaters Legion after their Primarch Angron took command was the stellar wasteland of the Golgotha Sector, located near the galactic core in the Segmentum Ultima, close to the realspace Warp rift known simply as the Maelstrom. Here, the World Eaters came upon the Sarum Sector, and the Forge World of Sarum, which was being besieged by the Abhuman empire known as the Brotherhood of Ruin who wished to take the Mechanicum's technological secrets for themselves. The World Eaters immediately launched a brutal assault upon the Abhuman army and slaughtered them. The Redjak Cult Mechanicum Tech-priests swore to Angron and his Legion directly many oaths of fealty and entered pacts of mutual protection and support. This provided the World Eaters and their Techmarines with a ready source of resupply and armament far outside the Imperium's inner sphere. The campaign that was to follow would last eleven standard years and see no fewer than 48 worlds and outposts ravaged and destroyed by the World Eaters, and 7 separate, dangerous xenos species, including a branch of the Lacrymole, rendered extinct. The XII Legion's fleet cut a swathe of destruction through the wastes of Golgotha, and even into the Maelstrom itself.ca. 900s.M30 Liberation of Alpha Shalish - It was during the XII Legion's campaign in the Golgotha Sector that the World Eaters' 203rd Expeditionary Fleet encountered the Lacrymole-infested world of Alpha Shalish. Remembrancers and Imperial artist-scribes of the 203rd Expeditionary Fleet recorded the auspicious events surrounding the liberation of the xenos-controlled world of Alpha Shalish. The Imperial forces, spearheaded by World Eaters Space Marines, burst into the mounded Lacrymole cities with righteous fury, cleansing the planet of their foul, man-eating kind with extreme prejudice.ca. 900s.M30 Ghenna Massacre - As the Great Crusade wore on, there were increasingly those in the Imperial military who whispered that Angron was mad and his Legion had followed with him into madness. These whispers became openly voiced as widespread discontent and demands for censure of the Primarch when stories began to circulate that Angron had ordered his Apothecarion to conduct widespread psycho-surgery and implant the so-called Butcher's Nails cranial implants in his Astartes once the infamous Ghenna Massacre came to light. This action, undertaken at Angron's instigation, resulted in the entire planetary population of the world of Ghenna that had rebelled against its installed Imperial Commander being wiped out in a single night of extraordinary bloodshed. The psychic screams of the dying were reported to have been audible by Astropaths half a sector distant.ca. 900s.M30 Night of the Wolf - After the Ghenna Massacre, the Emperor was moved to act and called Angron before Him for reprimand. He sent Leman Russ and his Space Wolves Legion to Ghenna, intending for Angron to submit before them and then be brought back to Terra for judgement and censure. Russ warned Angron that the Emperor had ordered the end of such prohibited psycho-surgery like the implantation of the Butcher's Nails in the Legion. Though the Wolf King tried to talk sense into his blood-maddened brother, Angron refused to listen to reason. Eventually, with tensions rising on both sides, an inevitable confrontation took place. No one is exactly sure who started the melee, but Russ wisely chose to order his Legion to withdraw, as both Legions faced mutual annihilation if they continued their course. The World Eaters were later issued with orders to depart to the northern fringes of known space, there to harry and reave against xenos far from the Imperium's core worlds, where their uncontrolled savagery could be harnessed productively without risks to civilian populations.921.M30 Keylek Genocide - Early in the Great Crusade the Luna Wolves encountered the hostile alien reptilian race known as the Keylekid on the world of Keylek. The grotesque Keylekid were greatly skilled in the arts of combat, and rose against the XVI Legion angrily the moment the 63rd Expeditionary Fleet made contact. This genocidal campaign proved to be a long, bloody, and miserable affair for the Luna Wolves.921.M30 Emergence of Koorqosan - The lost world of Koorqosan, brought to Compliance a hundred Terran years previously and then enveloped by the Warp, reappears upon the immaterial waves of the Messier 16 Nebula. The world appears to have experienced the accelerated passage of time in reverse, providing a glimpse at the secrets of Mankind's earliest exploration of the stars.922.M30 Discovery of Corvus Corax - Raised by prisoners on the mine-moon Lycaeus, Primarch Corvus Corax leads a revolution and renames his home Deliverance. When the Emperor arrives in the Principia Imperialis fleet, the two hold a secret conversation which lasts a solar day and a night -- after which Corax is left to subjugate the world of Kiavahr alone, and ultimately agrees to lead the XIX Legion. Corax quickly transformed his Legion in his own image and renamed them the Raven Guard.927.M30 The Cryptosi Purgation - When an exotic, meta-dimensional strain of xenos thought to be the species later referred to in some accounts as the "Cryptosi" was encountered in the northern reaches of the galaxy, a sub-company from the Alpha Legion was sent to the Imperium's northern reaches to investigate atrocities that the Cryptoisi were said to have committed. This campaign appears not to have been committed to record, although contact with human colony worlds in that region was lost soon after, seemingly as a result of Legiones Astartes activity.927.M30 Discovery of [REDCATED] - Records expunged.933.M30 Third Temporaferrox Extermination - The Iron Warriors' 33rd Grand Battalion successfully conducted a xenocide campaign against the Temporaferrox xenos. Though they suffered 78% percent casualties, all of the xenos life-forms were destroyed. The Iron Warriors' High Command deems these losses acceptable.939.M30 The Mystery of Novo Andruss - A force identifying as the "Ghost Legion" appears unheralded on the rebellious world of Novo Andruss. Uncharted psychic phenomenon are unleashed and then quelled in a brief but bloody conflict which brings the world back into Compliance, though superstition is heightened amongst the populace as a result.941.M30 Compliance of 63-8 (Davin) - The Feral World of Davin is brought into Imperial Compliance by the Luna Wolves Legion. The primitive Davinite warrior tribes were allowed to remain mostly intact as they had impressed Horus with their courage on the battlefield and their willingness to learn to adapt to Imperial culture. The Luna Wolves departed after the surrender of the Davinites, taking with them their concept of the Warrior Lodge, which were quickly adopted throughout the Luna Wolves fleet. A detachment of the XVII Legion, the Word Bearers (then known as the "Imperial Heralds"), under the command of First Captain Kor Phaeron, was left to shepherd the people of Davin into the light of the Imperial Truth. The Imperial governorship of the planet was give to Commander Eugen Temba of the Imperial Army, a close friend and confidante of Horus.942.M30 Colonisation of Gethsamaine - The world of Gethsamaine is found by Imperial Merchant Fleet Captains on the far edge of the Cyclops Cluster. It was accidentally discovered after a Chartist liner went off-course in an attempted passage of the void between M'Pandex and Zarnov. Gethsamaine was found to be a lush, primordial world of steaming rain forests filled with primitive flora, but where multicellular animal life had not yet developed. It was immediately identified as a prime location for human colonisation, and soon numerous Warp-arks filled with the teeming hives of the Segmentum Solar colonised the newly-discovered world. Gethsamaine was founded with the hopes of becoming the cornerstone of a new era of human expansion to further consolidate and exploit the nearby stars.943.M30 The Melkeji Salvation - The Imperium encounters a civilisation subjugated by a parasitic alien race which feasts on human sentience. Breaking the strongholds of the parasite hosts, recorded as "the Ascended," the Word Bearers Legion bring Melkeji to Imperial Compliance.ca. 945.M30 Battle of Sigma 51-7 (Sarosh) - Shortly after their entry into the Great Crusade, the 4th Expeditionary Fleet of the Dark Angels reached the orbit of the planet Sarosh (officially codified as Sigma Five-One-Seven), which had formerly been commanded by an officer of the White Scars Legion. The Saroshi -- ruled by a bureaucracy -- had recently expressed their interest in becoming part of the Imperium, and the Imperials were eager to allow them in, believing that these people seemed to express the same materialist beliefs as the Imperial Truth. But the Saroshi (without mentioning it to the Imperial expedition) secretly worshipped Chaotic entities in the Warp they called the Melachim, and saw the anti-religious stance of the Imperium's Imperial Truth as unsuppressed evil. The Lord High Exacter, the leader of the Saroshi bureaucracy, denounced Jonson and the Emperor to the Primarch's face aboard the Dark Angels' flagship, and Lion El'Jonson responded by ramming his blade, the Lion Sword, through the fanatical Saroshi leader's body. Unknown to the Dark Angels, the Saroshi had secreted a nuclear device aboard their shuttle, intending to assassinate the fleet's entire command structure, including Jonson; however, Luther and a junior Librarian named Zahariel managed to eject the shuttle into space, causing only minor damage to the flagship. After this incident, Luther, Zahariel and five hundred other Dark Angels were sent back to Caliban in disgrace, for allowing an enemy to get a nuclear device aboard the Primarch's flagship. They were ordered to oversee the recruitment of new Space Marines into the I Legion from the Calibanite population.ca. 900s.M30 The Carinae Retribution - The conquest of the Carinae Sodality remains a black mark on the record of the Raven Guard, a campaign whose details, long suppressed by factions within the Officio Militaris, show the Raven Guard as directly responsible for the campaign's delay and the excessive casualties recorded by the Imperial Army units assigned to the fighting. The Raven Guard were assigned to pacify the "Thousand Moons of Carinae" -- immense void-cities that circled the otherwise planet-less primary. On one such moon, designated Zenith-312, the cities' Arch-Comptroller unleashed a terrible weapon -- an anima-phage of terrible potency that rendered men into creatures of rage and hunger, bereft of all reason and memory. The Raven Guard suffered little ill-effect due to their genetically-enhanced immune systems, but the ordinary citizens of Zenith-312 and the mortal soldiers of the Imperial Army were reduced to a frothing, mindless horde that numbered in the tens of thousands. Immediately, the Raven Guard found themselves beset on all sides, and were forced to put down those who they once called allies, granting them the mercy of death. In revenge, Corax hunted down the escaped Arch-Comptroller, and enacted a brutal and long, drawn-out death. But in their need for revenge, the Raven Guard were neglectful in their duty, allowing for the other moons to fortify themselves, drawing out what was supposed to be a relatively swift Imperial Compliance action for seven long solar months, costing thousands of Imperial lives in the process.ca. 900s.M30 The Fall of the Lords of Gardinaal - The Gardinaal was a stellar empire comprised of eleven inhabited worlds encountered at the edge of the Dominion of Storms to the galactic east. They were an empire who possessed a considerable might of arms, enough to give even the Expeditionary Fleets of the Great Crusade pause. When an honour guard of Thousands Sons were sent to meet with the lords of Gardinaal, at first the negotiations went well, but unfortunately, the Thousand Sons were able to detect a psychic attempt to subvert the Imperial emissaries. The nearby Ultramarines 413th Expeditionary Fleet, commanded by Master Ulan Cicerus of the XV Chapter, was forced to intervene militarily. But soon their gains were forestalled by the superior defences of Gardinaal Prime, which proved disastrous, as they utilised powerful STC-based weaponry and vehicles never encountered by the Imperials before. A blockade of the Gardinaal System was employed. The stalemate was soon broken by a new war-host led by the Iron Hands and the Emperor's Children Legions. The Emperor's Children contingent launched a diversionary attack, while the Iron Hands led a relentless and tireless assault spread over every world. The Ultramarines requested to lead the assault on the capital city to restore some of their lost honour, though the blood price they paid was steep. The Iron Hands fleet left the Gardinaal System shortly afterwards, its other inhabited worlds pleased to surrender unconditionally to the Imperium's mercy. Though initially faced with famine and hardship, Gardinaal soon proved a valuable addition to the Imperium and a model of Imperial Compliance.ca. 900s.M30 Defence of Necromunda - At some unknown date later in the Great Crusade, the Imperial Fists Legion won a major victory against the Orks upon the ash wastes of the Hive World of Necromunda. The Hive Lords consented to new Imperial Fists recruits being drawn from their population in gratitude and a fortress-chapel was duly consecrated, but the Imperial Fists continued to refuse to accept any special political or economic rights on the worlds where their Legion recruited. Throughout the Great Crusade, they refused to garrison or claim tithes of newly conquered worlds, instead opting to remain a military unit with none of the other responsibilities that came with ruling a single homeworld and caring for its mortal population.ca. 900s.M30 Krypt Persecution - The Compliance of Krypt was a relatively short campaign conducted during the Great Crusade by both the Death Guard and the Luna Wolves Legions against the Orks upon the frozen plains of the world of Krypt. Fighting together for more than a solar week across the frozen surface of the planet, the Legiones Astartes turned the blue ice dark with xenos blood. Battle-Captain Nathaniel Garro and his 7th Great Company were known to have fought alongside the Luna Wolves' Captain Garviel Loken and his 10th Company during this action.ca. 900s.M30 Battle of Gyros-Thravian - The Battle of Gyros-Thravian was a massive joint-Imperial Compliance action carried out by three Space Marine Legions, composed of the Luna Wolves, Death Guard and Imperial Fists against the extremely powerful Ork Warboss Gharkul Blackfang, one of the most powerful Ork Warlords ever encountered up until that time. Despite the strength arrayed against the Greenskin, it was the Imperial forces who were soon on the verge of defeat. It was then that the Emperor Himself, aboard his flagship Bucephelus, came to the aid of His sons with his Principia Imperialis fleet. He personally led a force composed of 1,000 Legio Custodes into the heart of the mighty Ork horde. Blackfang was confronted by the Emperor and killed atop his Gargant while the Custodians proceeded to lay waste to the rest of the Greenskin horde. The Custodians accounted for the slaughter of the Orks, slaying over 100,000 of the savage xenos, with the loss of only three Custodians. Following their momentous victory, the Emperor commemorated the Custodians' sacrifice by engraving the names of the three fallen into his own personal Artificer Armour.954.M30 The Screaming World - The Ultramarines Legion is drawn to the world of Volturn, thought to already be Compliant, by the petitioning of the Legion's Librarians, who claim to hear inhuman screaming emanating from its location. Upon investigation, the world is found to be infested by ill-definable xenos creatures. Volturn is quarantined and abandoned after all members of the landing party suffer spontaneous and fatal cerebral aneurysms within solar minutes of setting foot upon the damned, screaming world.ca. 957.M30 The Melkeji Salvation - The world of Melkeji was a planet on the trailing edge of the galactic rim which had retained many of the technological marvels of Mankind's Dark Age of Technology. Unfortunately, the human population was enthralled to nameless parasitic xenos creatures that ruled Melkeji through a class referred to as "the Ascended." Knowing that they could not capture the planet, the Grand Marshal of the Expeditionary Fleet sent an Astropathic message asking for aid. Lorgar himself came to Melkeji with eight full Chapters of his XVII Legion and the aid of the Imperial Army. Through Lorgar's tactical genius and superb guile, he overwhelmingly defeated the xenos. The people of Melkeji knew that their masters were gone and that they were facing a power greater and more terrible than any they could have dreamed in their wildest nightmares. Most of the Melkeji surrendered at that moment, the rest a few solar days later. A solar decade after, Melkeji was a world faithful to the God-Emperor. Nearly a solar decade after that, half a million of its sons and daughters would come to Ultramar in 007.M31 with the names of alien gods on their lips and aid the Word Bearers in the assault upon Calth as Chaos Cultists.962.M30 Pacification of the Saryine Compact - The Iron Warriors' 282nd Grand Battalion successfully conducted the Pacification of the Saryine Compact, reducing rebellious garrison forces to 30% effective strength. The 282nd Grand Battalion suffered only 32% casualties, which lead the Battalion command to be censured by the Iron Warriors High Command for its lack of zeal.962.M30 The Defence of Helioret - The insane Witch Idol of the Aeldari Craftworld of Magc'Sithraal led a brutal campaign of raids against the world of Helioret, perpetrating etheric outrages across the sector. The combined forces of the Blood Angels and the Ordo Sinister bring down the Witch-Idol and cast the Craftworld into the local star.964.M30 The Razing of Monarchia - Monarchia was the name of the capital city of the planet Khur, built as a beautiful shrine to the God-Emperor by the XVII Legion, the Word Bearers, during the Great Crusade. Monarchia, along with its false temples dedicated to the divinity of the Emperor in direct contravention of the official atheism of the Imperial Truth, was destroyed by the warriors of the Ultramarines Legion as an object lesson in the folly of false religion. The entirety of the XVII Legion was then forced to kneel in the ashes of their devotion by the psychic might of the Emperor Himself, while the Ultramarines stood over them in judgement -- that which they had seen as worthy devotion now labelled treasonous. Suffering such a humiliating rebuke at the hands of the Ultramarines, this insult would apparently fester within the XVII Legion and drive them willingly into heresy and the service of the Ruinous Powers -- gods worthy of their need to believe.965.M30 Compliance of 47-16 - Forty-Seven Sixteen was the first world brought into Imperial Compliance after the rebuke of the Word Bearers by the Emperor on the world of Khur. The lost human world had at first rejoiced to be reunited with their long-lost brothers from the stars. But the Word Bearers immediately initiated military action in the form of an orbital bombardment that wiped out nearly every single city with the exception of one. The now corrupted XVII Legion used the excuse that they did not have the time necessary to convert the population of Forty-Seven Sixteen to the Imperial Truth, and since their supposedly profane beliefs were deemed incompatible with the Imperium's materialist order, the world of Forty-Seven Sixteen would have to be purged. The Word Bearers' Primarch Lorgar dismissed the fact that the people of this world worshiped the Emperor as a god and that they had somehow obtained a copy of the Lectitio Divinitatus scribed by Lorgar himself. The people of Forty-Seven Sixteen were condemned, for ignorance was no excuse for violations of the Imperial Truth.965.M30 <ALL DATA REDACTED> - Unknown event. Data fragments indicate the involvement of the Space Wolves Legion.966.M30 Discovery of Cadia - The Word Bearers were the first to discover the world of Cadia during the so-called "Pilgrimage of Lorgar", the spiritual quest undertaken by the Primarch Lorgar and his XVII Legion to commune with the Dark Gods who they believed to be the ancient deities of their homeworld Colchis. The Word Bearers' pursuit of any scrap of information that could be found on the Primordial Truth or the nature of the place where gods and mortals could mingle ultimately led the 1301st Expeditionary Fleet to the Cadia System near the largest permanent Warp Storm in the galaxy, later known to the Imperium as the Eye of Terror. The Word Bearers laid anchor over an unknown world. They later made planetfall on the newly discovered planet, which they designated as 1301-12. There, they discovered that its population worshipped Chaos openly. It was on Cadia that Lorgar first met Ingethal, a Daemon Prince of Chaos, who was appointed by the Ruinous Powers as a guide for Lorgar and inducted the naïve Primarch into the worship of the Ruinous Powers. Lorgar's conversion would set in motion the events that brought on the cataclysmic Horus Heresy nearly four solar decades later.ca. Mid-900s.M30 Battle of Byzanthis - A Dark Angels' Expeditionary Fleet, under the command of Chapter Master Merir Astelan, discovered the far-flung world of Byzanthis during their exploration of star system DX-619. Following this discovery, another Dark Angels force, under the command of Chapter Master Belath, arrived in-system. The two opposing Dark Angels commanders advocated different approaches in the Compliance of the newly discovered world -- Belath wanted to use military force, while Astelan preferred to try diplomacy to win over the planet's population. However, hostilities soon broke out after an engagement between the Dark Angels and defence forces of Byzanthis, which the Legionaries easily dominated. Determined to continue a diplomatic approach, Astelan went before the Byzanthis planetary government to plead his cause for Byzanthis to accept the Imperial Truth and join the Imperium. The proceedings were interrupted when Belath teleported directly into the session with a Terminator retinue, who proceeded to slaughter the Byzanthis delegation. Enraged, Astelan knew war was now inevitable. A campaign was fought that eventually forced Byzanthis into Imperial Compliance.969.M30<ALL DATA REDACTED> - Unknown event. Data fragments indicate the involvement of the Space Wolves Legion.970.M30 Pacification of Zaramund - A joint-Compliance campaign on the world of Zaramund was conducted by the Luna Wolves and a contingent of the Death Guard led by First Captain Calas Typhon and a contingent of Dark Angels led by Luther, the acting Regent of Caliban. Following their victory, a celebration was held, but soon the festivities were marred when Lion El'Jonson arrived to rebuke Luther for disobeying his orders to remain on Caliban.972.M30 The Farinatus Extermination - <ALL DATA REDACTED> Unknown event. Data fragments indicate the involvement of the Night Lords and Raven Guard Legions.ca. 977.M30 The Breg-shei Eradication - On the world of Farinatus Maximus, a detachment of the Raven Guard under Commander Alkenor carry out a Writ of Annihilation against the xenos-species of the Breg-shei -- highly dangerous and hostile insectoid aliens that had evolved there. Operating alongside the VIII Legion, the Night Lords, the Raven Guard infiltration team led by Sergeant Dravian Klayde charged with collapsing the Breg-shei's nest was discovered and all were killed but for the tenacious Sergeant. Having lost one arm and both of his legs, Dravian Klayde still succeeded in reaching Imperial lines, dragging himself by his sole functional arm for solar days on end. This feat earned him the nickname of "The Carrion," bestowed upon him by the Night Lords who found him. Klayde would undergo extensive augmetic repairs which ultimately led him to be selected for training as a Techmarine on distant Mars, thus allowing him to be present during the later Schism of Mars and play an important role in it.977.M30 The Compliance of Dwell - Brought into Imperial Compliance peacefully by the Ultramarines, the world of Dwell is found to harbour an esoteric network of technologies of potentially xenos origin which predate the Age of Strife. This network is found to preserve and combine the memories and knowledge of Dwell's people upon death through ill-understood means.Late 970s.M30 Persecution of Vaomir Reaches - Encountered through highly unusual circumstances, the Night Lords take part in the protracted persecution of the void-born Gethora Warp-Witches across the Vaomir Reaches. This was done due to the Emperor's standing edict that any alpha-level rogue psykers that were encountered were to be destroyed outright, either through Exterminatus from orbit without direct confrontation or hunted down and slain with due prejudice. The purpose of this order was to prevent the truth of Chaos and the existence of those who promulgated such beliefs from being revealed and casting doubt on the Emperor's extorted tenets of the Imperial Truth.976.M30 Compliance of Dwell - The world of Dwell was brought into Imperial Compliance by the Ultramarines Legion, led by Roboute Guilliman himself. This world, settled during the Dark Age of Technology by settlers from Molech, contained a vast repository of information that would later lead the Chaos-corrupted Warmaster Horus to Molech in search of the origin of the Emperor's power.981.M30 Discovery of Alpharius Omegon - Conflicting reports surround the return of the Primarch Alpharius to the XX Legion. Some claim he was found leading a renegade fleet by Horus himself, or saved by the Emperor from the alien Slaugth. Others suggest he was marooned upon a Dead World -- or was never lost at all, but raised on Terra itself. Of the complete truth, none can tell. One extant account states that Alpharius was discovered accidentally by the Luna Wolves when they were lured into a trap after receiving a distress beacon from one of their own battleships. When they went to assist, Horus's flagship Vengeful Spirit came under attack by an unknown enemy, and a single assassin broke into the flagship and fought his way clear to Horus' command chamber. Horus himself was forced to confront him, but thankfully, did not slay his attacker but recognised him instead as his lost brother primarch -- Alpharius. Unfortunately, the validity of this account is considered highly suspect, as is so much else about the Alpha Legion and its primarchs.981.M30 Alpharius Assumes Command of the XX Legion - <RECORDS NOT AVAILABLE>981.M30 Burning of the Pharun Drift - The Iron Warriors of the 3rd, 14th and 72nd Grand Battalions successfully subjugate the rebellious population of the Pharun Drift, suffering an overall casualty rate of 42%. The 3rd Grand Battalion suffers 80% casualties. All of the target worlds are depopulated. These losses are deemed acceptable by Primarch Perturabo.984.M30 Pacification of the Cheraut System - Following the successful joint-Compliance action of the Cheraut System, the three Primarchs of the Emperor's Children, Night Lords and Imperial Fists Legions met in celebration. After the celebration, the Night Lords Primarch suffered one of the violent fits that often plagued him, and Fulgrim rushed to Konrad Curze's aid. The Night Haunter then confided in his brother the dire visions that he had seen; his death at the hands of their father, that many of the Primarchs would die fighting amongst themselves, and that the light the Emperor brought to his homeworld of Nostramo would destroy it forever. Troubled by these dire portents, Fulgrim confided in his brother Rogal Dorn. Dorn took exception to this slight on the Emperor's name and confronted Curze. Shortly thereafter, Dorn was found unconscious and bleeding with great gouges of flesh ripped away from his torso. Crouching above his fallen brother was the pallid form of the Night Haunter, weeping. Wracked with self-loathing and guilt, Curze was taken into custody and exiled to his chambers, while his brother Primarchs discussed what actions to take against their deeply disturbed brother. Solar hours later, when the council of Primarchs finally disbanded, they found Night Haunter missing and the Imperial Fists' honour guard watching over him butchered. By the time the Primarchs gave chase, Night Haunter had already disappeared with his Legion into the Warp.984.M30 The Destruction of Nostramo - The destruction of Nostramo was an Exterminatus action conducted by the now-rogue Night Lords Legion after the Night Haunter's attack on Rogal Dorn towards the end of the Great Crusade, following the pacification of Cheraut. The VIII Legion willingly destroyed their own homeworld of Nostramo on the order of their Primarch, concentrating deadly Lance-strikes on the planet's unstable core, which resulted in tumultuous seismic activity that eventually ripped the dark planet apart in a wave of destruction. This event fulfilled the Night Haunter's vision of seeing his planet being destroyed by beams of white light that erupted from the heavens. For this crime, Curze was eventually recalled to Terra by the Emperor to be reprimanded for his brutal tactics, but instead he would join the Warmaster Horus in open rebellion during the Horus Heresy before he could ever stand before his father.987.M30 The Compliance of Indra-sul - On the world of Indra-sul, the Raven Guard infiltrate the home of the monstrous xenos Khrave and wage a guerilla campaign to defeat the gluttonous, warped creatures within, in their efforts to liberate the human population the Khrave dominate. The Khrave and their edifice are cast down, freeing Indra-sul.988.M30 The Mariposa Campaign - A pocket of space comprising 12 sub-sectors is released from a Warp Storm which had raged from the time of the Age of Strife. For three Terran years, the Blood Angels, Imperial Fists, Imperial Army and Sisters of Silence battle against hordes of Warp-twisted cults of the mutant and the psyker, brining 34 new worlds into Imperial Compliance.989.M30 Hunting of the Ak'Haireth - In 986.M30, reports of attacks against isolated outposts and shipping in the region of the stellar wastes near Olmec indicated that the Ak'Haireth -- a fungoid parasitic lifeform whose sentience was only acquired from operating as psychically interwoven gestalt blooms, and whose existence was fueled by a the slow and agonisingly painful siphoning of nutrition from living animals -- were again dangerously growing in strength and number. The Alpha Legion were assigned the xenocide of the species before it could spread further. Within three sidereal years, they accomplished this feat by working in conjunction with the Magi Biologis and creating a deadly, genetically-targeted bio-weapon that poisoned the source of the Bone Drinkers' nourishment -- the humans that lived on the worlds and plied the stars near Olmec. The malignancy of the virus caused those Ak'Haireth that fed on the targeted populations to fall ill and die -- at the cost of also killing 7% of those humans who had been infected with the virus. But the Ak'Haireth species had been caught unawares and was finally driven to extinction.ca. 990.M30 Xenocide of the Khrave - Corax and his Raven Guard Legion were deployed in the far galactic north, pressing the Great Crusade's expansion past the reaches of the Segmentum Obscurus, when they discovered the world of Indra-sûl, and the greatest Khrave dominion encountered so far in Imperial history. The Khrave were a dangerous species of psychically-gifted xenos that preyed on human worlds, enslaving entire populations to feast on them and thus strengthening themselves. After a protracted and bloody campaign, Corax successfully wiped out the Khrave and liberated Indra-sûl from their xenos masters. Unknown to the Raven Guard, the Iterators and other Imperial servants following on the heels of the XIX Legion's advance would later condemn the survivors to a living death as lobotomised Servitor labourers, seeing them as corrupted in both mind and body.Mid-900s.M30 Siege of Barrakan - This was an Imperial Compliance action carried out by the Dark Angels during the Great Crusade against the Orks on the world of Barrakan. A notable campaign of this Compliance action was the defence of Firebase Endriago. A Chapter of the Dark Angels had been cut off by the Greenskins and trapped at the firebase for 18 solar months. By the end, the beleaguered Astartes were fighting off the alien assaults with fists and pieces of sharpened steel scavenged from bombed-out strongpoints, but through it all, Brother Nemiel had never wavered. He had taunted the Greenskins relentlessly and exhorted his brothers to acts of ever-greater defiance in the face of insurmountable odds. When a Greenskin's crude axe had shattered his knee, he had grabbed the beast by one of its tusks and kicked it to death just for spite. When the last line of defence was broken, he had stood his ground in the face of a massive xenos champion and fought an epic duel that had given the Chapter time to launch a counterattack that finally exhausted the last of the enemy's strength. The next day, when relief forces finally managed to fight their way through to the firebase, Nemiel had stood on the ramparts and cheered with the rest of his brothers. It took several solar minutes before he registered the slaps on his shoulders and back and realised that the Chapter was not cheering for victory -- they were cheering for him. Not long after, the Chapter voted unanimously for him to take the place of Brother-Redemptor Barthiel, who had fallen during the darkest hours of the siege.994.M30 Istvaan System first brought to Imperial Compliance - One of the more notable campaigns carried out by Primarch Corvus Corax and his Raven Guard Legion during the Great Crusade was the Imperial Compliance of the Istvaan System in 994.M30, located in the northern reaches of Segmentum Ultima. The Istvaan System had required force to impose Compliance, so an outlander was chosen rather than a local to rule, and this task was given to Vardus Praal, formerly a Major of the XIth Lastran Rifles of the Imperial Army and later a career politician of the Ultima Segmentum Court.ca. 995.M30 Pacification of the Hith System - Approximately a solar decade prior to the events of the Istvaan III Atrocity, the pacification of the Hith System against the Orks of Charhack was the largest concentration of Imperial military force ever seen to that time, omprising well over 200,000 Space Marines, although exact figures could not be corroborated. These Legiones Astartes fought alongside Titan support from the Legios Mortis, Audax and Vulpa and a number of auxiliary units.ca. 997.M30 Subjugation of Kernunnos - The Space Wolves' 954th Expeditionary Fleet, comprised of the Space Wolves 13th Company under Wolf Lord Bulveye, successfully completes the conquest of the non-Compliant human world of Kernunnos.998.M30-005.M31 Suppression of the Gordian League - The Dark Angels fought this Compliance campaign against the Gordian League -- a confederation of human worlds who were allied with degenerate xenos. The Dark Angels were still bogged down during this campaign in 005.M31, when they received word of Horus' treachery at Istvaan III, as well as the secession of the World Eaters, Emperor's Children and the Death Guard Legions. Jonson believed that the Dark Angels' deployment to the Shield Worlds was part of an effort to scatter the Imperium's most loyal servants as far as possible in order to minimise the number of Loyalist Legions Horus would have to face at any given time. Jonson's forces were too deeply enmeshed in the Shield Worlds to respond quickly to Horus' treachery; the best estimates of the Primarch's staff indicated that it would take them nearly eight solar months to conclude their offensive operations, even on an emergency basis, and reposition themselves for a strike against Istvaan V. The Primarch issued orders for many of their reserve squadrons to resupply and prepare for immediate deployment to the Tanagra System. Their primary target was to secure the Forge World of Diamat. They could not afford to let the Warmaster acquire the substantial supplies and ordnance needed to fortify the world of Istvaan V against the approaching Loyalist strike force. Jonson personally lead the expedition to Diamat, with a battle group of fifteen warships.ca. 999.M30 Compliance of Melchior - The Imperial Compliance of Melchior was a joint campaign that was carried out by both the Luna Wolves and the Blood Angels Legions. The world was the last bastion of the xenos known as the "Nephilim" -- a parasitic alien race that slowly fed on humans and had claimed a hundred worlds before they had come to rest upon Melchior. Even their name, the Nephilim, the name of the fallen seraphs, was a name taken from ancient human mythology. The Luna Wolves and Blood Angels stood shoulder-to-shoulder and brought their full, unfettered wrath down upon the upstart xenos. Caught between the brutal fury of two Space Marine Legions on Melchior's shining sands, the Nephilim were finally put to the sword.ca. 999.M30 Pacification of Aghoru - The Aghoru Campaign was an Imperial Compliance action carried out by the then-loyal Thousand Sons and a small contingent of the Space Wolves Legion in the waning years of the Great Crusade. Though Imperial Compliance was successfully accomplished through diplomacy and considered a success, soon notable combat actions took place between the Thousand Sons and an apparent Warp denizen infestation of beings known to the local population as "Elohim" within the subterranean passages of the vast artificial peak known as "The Mountain." The Space Wolves helped to put down this infestation.999.M30 World-Prince Campaign - This was one of the final campaigns fought by the Imperial Fists during the waning years of the Great Crusade upon an unnamed Hive World against a non-Compliant human civilisation ruled over by a monarch known as the World-Prince. Initially, the World-Prince had refused to surrender to the Imperium and stubbornly resisted the efforts of the Imperial Fists led by Rogal Dorn himself. The Imperial Fists systematically fought one hive city at time, and were making slow but steady progress, until the Alpha Legion arrived unexpectedly. Informing their fellow Legion that they were there as allies in the campaign, the Alpha Legion immediately began to begin operations against the intransigent world. Though no Alpha Legion warriors were encountered by the Imperial Fists during the campaign on the ground, the signature of their presence was abundantly clear, as soon, uprisings and coups began to erupt across the remaining hives, which threw the beleaguered world into absolute anarchy. Following the death of over 400 members of the World-Prince's nobility, he capitulated to Dorn. Enraged, Rogal Dorn confronted Alpharius and scorned him for his disreputable way of waging war. He then ordered the Alpha Legion to cease all operations and leave the planet. In one final act of spite, Dorn proceeded to lay out the Alpha Legion's entire plan, and poked holes in its overall effectiveness, before walking away in disgust.ca. 999.M30 Compliance of 670-25 (Nurth) - The Alpha Legion responds to requests for aid from the 670th Expeditionary Fleet to take part in the Imperial Compliance of the world of Nurth. Unfortunately, the planet is lost when a Chaos-tainted local military force, known as the Echvehnurth, activated a Warp-tainted artefact called a Black Cube as a last act of defiance. Once activated, Nurth was transformed into a world inimical to all sentient life nearly overnight, killing most of the Imperial forces on the ground.000.M30 Alpha Legion Makes Contact with the Cabal - According to the Unbalanced Scales, this year marks the beginning of the Alpha Legion's compact with the xenos faction known as the Cabal.ca. 000.M30 The Ullanor Crusade - The Ullanor Crusade was a vast Imperial assault on the Ork Empire of the Overlord Urrlak Urruk on the world of Ullanor Prime, the largest such Greenskin empire ever encountered in Mankind's history to that time. The Crusade included the deployment of 100,000 Space Marines, 8,000,000 Imperial Army troops, a Titan Legion and thousands of Imperial starships and their support personnel. The Ullanor Crusade marked the high point of the Great Crusade's vast effort to reunite the scattered colony worlds of Humanity across the galaxy.000.M30 Triumph of Ullanor - Following the defeat of the Orks of Ullanor, the Emperor finally left the Great Crusade behind and returned to Terra to begin work on His vast, secret project to open up the Aeldari Webway for Mankind's use beneath the Imperial Palace. In His place to command the vast forces of the Great Crusade He left the Primarch Horus Lupercal, his most-favoured son, whom He raised to the newly-created rank of Imperial Warmaster. Horus received command authority over all of his fellow primarchs and every expeditionary fleet of the Great Crusade.
