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.
