Thousand Sons - Age of Burning, M41-M42: Note: All dates from this point forward are provisional due to errors in the Imperial Calendar, meaning these events could actually have occurred at any time from the early 41st Millennium to the early 42nd Millennium.Broken Shield (Unknown Date.M42) - The Cult of Manipulation forge a hex to extinguish the Aspis star in Segmentum Solar. The growing solar storm alerts the Adeptus Custodes to the Thousand Sons' machinations, and a squad of Allarus Custodians, joined by a Grey Knights strike force and a large contingent of Skitarii, set out to locate and eradicate the cabal, but as they approach the Aspis System an enormous solar flare separates the Imperial forces. While the Grey Knights and Skitarii find and destroy the profane wards sustaining the hex, the Adeptus Custodes are sent adrift through the Warp, into the clutches of the waiting Thousand Sons.The Invasion of the Stygius Sector (Unknown Date.M42) - Magnus the Red leads a devastating Chaos assault on the Stygius Sector. Cut off from the Astronomican, the Imperial defenders fall quickly to Chaos Cultist uprisings, daemonic invasions and attacks from scores of thrallbands. Only the stubbornness of the Mordian Iron Guard and the arrival of the Aeldari as part of the so-called Stygius Crusade prevent the sector from being overrun, though even these events have long been foreseen by Magnus, and are part of his wider plan for the transformation of Stygius.The Beast Within (Unknown Date.M42) - On the high-grav world of Krachordia, the Abhuman Ogryn tribes hunt down a mutant beast that has been roaming the stalagmite jungle. As they hack the writhing creature apart, they find an undulating sac lodged within its innards. The hunters feel a strange inclination to recover this mysterious growth, and so bring it to the tribal elders who deem it "good" and place it in the centre of their settlement. Over time the sac begins to shed light of multiple hues. Eventually it splits open and from within emerges a creature radiant and beautiful to the eyes of the tribesmen. To them it resembles a perfectly formed human, and they weep in the presence of its magnificence. As they fall to their knees in worship their own bodies begin to change, becoming more like the being they adore. Solar months later, the Astra Militarum fleets arrive to collect their tithe of warriors from Krachordia. They find no trace of the Ogryn tribes -- only a world overrun with hulking Chaos Spawn.The Impassable Sea (Unknown Date.M42) - Space Wolves from Engir Krakendoom's Great Company set a course for the Prospero System, hoping to reach the Planet of the Sorcerers and once more bring ruin to the Thousand Sons' homeworld. But no matter what path they take, eerily sentient Warp eddies fling them far off track.The Silent War (Unknown Date.M42) - A cloud of particulate dust falls over the heavily fortified spire-convent of the Sisters of Silence on Gassima. It is soon followed by a more destructive storm as suits of Rubric armour bearing the sigil of the Blades of Magnus fall from the sky like meteors, smashing through vaulted ceilings and cratering the courtyards. As the Sisters of Silence reel from the bombardment, sheets of lightning crack through the atmosphere and the dust cloud coalesces around the lifeless Rubric suits. The dust -- which is in fact the essence of Thousand Sons warriors -- pours into the armour, and one by one they stand up and raise their weapons. The spire-convent is obliterated in the battle, and every Sister of Silence slaughtered, though even faced with death not one allows herself to scream.Power Unbound (Unknown Date.M42) - In their war with the Necrons of the Nephrekh Dynasty, the Silver Sons loose a quartet of Heldrakes upon a Tesseract Vault. The winged monstrosities tear the prison open, freeing the C'tan Shard within and allowing it to begin a years-long rampage through Nephrekh space.The Psychophage of Mangel III (999.M41) - Hasophet and his Mind-Eaters descend upon the Imperial Hive World of Mangel III amidst an ongoing T'au invasion. Before landing the Sorcerer shatters the Shrouded Crystal in orbit, casting its shards throughout the atmosphere to summon an impenetrable darkness which surrounds the planet. Cut off from orbital reinforcements and relays, the T'au armies and planetary defence forces continue fighting in utter confusion. In the Valley of Sacrifice, between the lines of the battling armies, the Mind-Eaters array the trophies and fetishes acquired from their nine hundred and ninety-eight preceding rites in a great crescent, and between the horns of the crescent Hasophet mounts an enormous pyre. From its pinnacle he beholds the encroaching T'au and Imperial forces -- they are to be his, their thoughts and memories devoured as was foretold. Holding aloft the hearts of Korthuphos, Hasophet ignites his pyre with their blood, incanting an oath to Tzeentch as the flames begin to lap his armour. The sudden rush of psychic energy towards Hasophet shreds the minds of the hundreds of thousands of combatants on Mangel III, siphoning their very life force into the Sorcerer. But as the Grand Conspirator's changes take hold Hasophet screams in agony. The armies on the horizon are pulled physically towards him like gnats caught in a thundering vortex. Ranks of screaming bodies and enormous war engines fly across the darkened land, colliding with Hasophet where they are quickly absorbed by his warping form. His body devours metal and flesh with equal voraciousness as it continues to grow, howling in excruciation from newly forming maws. His mass pupates, not into the form of a Daemon Prince, but to that of a Mutalith Vortex Beast. The Warp vortex emanating from the hideous creature extends outwards with each newly consumed sacrifice until it encircles the planet, and with a final mind-tearing scream Mangel III itself is torn from realspace. In its place there is left only a perpetual dark shroud and an echo of Hasophet's final, pitiful cry.The Subsumation of the Exiles (Unknown Date.M42) - A dozen exiled sects are summoned by the Rehati to the Planet of the Sorcerers. Through psychic communication and blazing runes cast throughout the stars, the Rehati inform the leader of each sect that they have two options -- either consolidate their forces with the bulk of the Thousand Sons, or suffer the full wrath of their Primarch for refusing his clemency. Of those summoned, eleven arrive at the Planet of the Sorcerers. The returning armies are arrayed in the mustering grounds of Tizca wherein the Rehati begin the rites of reunification. As the final act of subservience, every living Sorcerer amongst the exiles is summoned to the Altar of Fates where nine drops of their blood are drawn and cast into the ever-burning fires. At this moment, the massed ranks of Rubric Marines and Scarab Occult Terminators from the eleven exiled sects turn to the Rehati, kneeling down before their new rulers in perfect unison. Rising, they simultaneously turn towards the Sorcerers huddled on the Altar of Fate, raise their weapons and unleash devastating payloads against their masters of old.The Road to Resurrection (Unknown Date.M42) - Having witnessed the ability of Yvraine to restore the Thousand Sons afflicted by the Rubric, Ahriman begins gathering his forces. After ten thousand years he knows where to find the knowledge he has been seeking, and so he trains his prescient vision on the Drukhari city of Commorragh.
