- Hardware: For the Thousand Sons Companies, the Rubric Marines still wear the same Mark V Heresy Pattern Power Armour their souls were bound to when the Sorcerer Ahriman cast his Rubric over ten millennia ago, with their Crusade-Pattern Bolters. Their Heavy Weapons are similarly ancient Plasma Guns, Autocannons, and Frag and Melta bombs. The Sorcerers bear the same armour type as their Rubric brothers, though they've adapted it and adjusted it for their desires as sorcerers, and are equipped with Staffs or Power Swords, and Bolt Pistols.

The Traitor Guardsmen are equipped with standard Lasrifles, Combat knifes, Swords, and Las pistols and Flak Armour of the Sagarius Imperial Divisions, though their armour has been defaced with icons of Tzeentch and other symbols of the Warp and Chaos. Some specialists among them wield Hell-guns, though they make up 1-2% of the force.

The Cultists wield a wide variety of weapons and armour, though most of it is patchwork. Their arsenal includes Lasrifles, Shotguns, Hesery Pattern Bolters (less than a handful of these to go around), Stub Pistols or Rifles, Clubs, Picks, Swords, Hammers, Lances, Sickles, Torches, and Crude explosives like Molotovs or IEDs. As for armour, most are wearing nothing to speak of besides robes or crude sheets of metal strapped together. Though some of them do wear scavenged Flak Armour from the murdered Loyalists, the majority do not, or at least not in complete sets.

The Armoured Divisions are a mix of Traitor vehicles and those which have been scavenged from the wrecked vehicles of the Loyalists during the uprising. Under Magos Orpheus, many were repaired or rebuilt and made fit for war, though now covered with icons of Tzeentch and blessings of the Lord of Change inscribed upon their hulls.

Background: The Reliquary of Metamorphisian Mysteries started as a back alley Cult of one of the many habs within the Hive world of Sagarius. Founded by a handful of low level pyskers and Mutated outcasts fearful of their fate at the hands of the Black Ships of the Inquisition, the agents of the Ecclesiarchy, or simply the scorn of their neighbours, they sought to improve their pitiful situation. Through their dreams and desires of something better for themselves, they garnered the attention of one of the ancient deities of the Warp, Tzeentch, the God of Change, Transformation, and Sorcery just to name a few of his aspects. He spoke whispers into their dreams, tempting them with the promise of a better future for themselves, one which lay within the ancient arcane and esoteric artifacts, texts, and inscriptions kept far and locked away from the prying eyes and ears of those deemed unworthy of them. He told them that within such things which held fragments of the Warp, or knowledge of the quintessential truths of the fabric of the universe lay the power and the ability to alter anything one desired. Their physical forms, their fortunes, their fates, anything could be within their reach if they obtained these things.

The Lord of Change's whispers did not go without result, the members met to discuss what course their little group should take, and several members broached the idea of trying to find these various forbidden texts, artifacts, inscriptions or items which may hold some promise. Each member felt likewise, though they could scarcely believe at the time that they had all reached a common purpose despite how heretical it was, and despite not having consulted one another on their dreams before hand. Tzeentch is the Great Manipulator, and these desperate psykers and mutants were but clay for him to mold to his designs, whether they succeeded or failed made little difference to him, for either way it opened new opportunities for his machinations and schemes to take root, but even he may have been pleasantly surprised at the results of this little ploy of his, or he may not. The mind of Tzeentch is impossible to discern to any but himself.

Regardless, the Reliquary set out on its mission, using guile, subterfuge, manipulation, and many underhand tactics, they slowly gathered a stockpile of forbidden lore and artifacts, starting out small with merely warp-touched bits of junk or scraps of heretical manifestos on Mutation and Transformation, and kept them hidden in their lair far in the depths of the Hive. There, they examined and poured over what they found, seeking enlightenment and knowledge as to what they could do to improve their lot. Throughout this time, they also slowly expanded their numbers, taking in more mutants, latent or rogue psykers, or simply those down on their luck and miserable for a better existence. They took anyone, Hobos, Drunks, Orphans, Prostitutes, decommissioned Clerks, Adepts, Arbites or Guardsmen, anyone who believed in their goals. Slowly, their position of power began to grow throughout the Hive.

As years went by, they became more organized, forming sections within their cult with everyone being assigned specific roles and ranks, with each being privy to different things, and most not knowing enough to compromise the whole cult. Their collection also began to grow, with more significant pieces coming into their possession via thievery, black market bartering, or outright taking (though the Reliquary was careful in using intermediaries more often than its own forces to try commit such acts in these days still), though it was still nothing that would earn them a Witch-Hunt from the Ecclesiarchy or draw the suspicions of the Inquisition, they were making progress. Their psyker members began trying to use what they acquired, to understand and awake their powers, and to try and make their fellow members' lives easier (though at this stage, this meant blocking out pains, depression, and other small issues), later this would take a darker turn.

For Tzeentch whispered more temptations into the ears of his mostly unknowing devouted, ones which promised them freedom from their existence in the process of transforming their human forms into something greater. He utilized the examples of the Emperor's Astartes, who were not human themselves and what they had become through the process of transformation, undergoing a metamorphosis into something greater than the pathetic things they once were. Unable to resist the suggestions of a God, the Reliquary began attempting various minor experiments on voluntary members of their cult. They sought to heal mutants at first, returning sight to those who were blind, giving great strength to the weak, and mending those who bodies were broken, simple things. The results were terrifying to behold, but the Mutated, or in many cases further mutated humans obtained that which they desired, which was more than what could be said about the Imperium which had cast them away.

Utilizing their mutated brethren and sisters along with their growing range of intermediaries and forces, the Reliquary became bolder, pulling off even greater robberies and heists of forbidden items, the investigations into them reaching dead-ends or contrived conclusions on behalf of the Reliquary's manipulations. This of course, all built up to their biggest achievement, a attempted communion with the God whom they now understood to be speaking to them. Conducting the most elaborate ritual they'd contrived yet from the lore, artifacts, and knowledge they had obtained, they managed to open a tear in the fragment of reality, a portal to the Warp, no bigger than a doorway, but a portal nonetheless. Through that door walked a blue and gold Astartes from millennia long past, robed with symbols of Tzeentch, wielding a runed blade which dripping eldritch power, and whose psychic radiance made the gathered psykers of the Reliquary tremble, he introduced himself as Dionysos Xanthous, Sorcerer-Lord of the Thousand Sons Legion, the sons of Magnus the Red and greatest mortal servants of Lord Tzeentch.

He informed the Reliquary of their Lord's pleasure at their success in opening the way for this moment, where they would crawl out of the shadows and throw down those who sought to keep the knowledge and artifacts they sought locked away, the Imperial Administration. For Dionysos convinced them that the Imperials would never change in their ways unless forced to, and it was their task to fulfill Tzeentch's will and bring about this change now, and turn the worlds over to their Lord as gifts. He said that in exchange, Tzeentch would grant them power and illumination beyond reckoning. Dionysos was manipulating the Reliquary of course, just as the Reliquary manipulated their intermediaries, but it wasn't entirely false, they would be rewarded for their loyal service, if they lived and proved their worth.

For now dozens of Rubicon Marines and fellow Sorcerers made their way through the portal over the weeks, Dionysos's war band, and with them came the experience of centuries of arcane mastery and occult knowledge, let alone warfare. In less than 3 months multiple portals were active, bringing in many of the Thousands Sons daily from The Planet of Sorcerers, which was apparently where the portals linked to. Once they reached critcal mass, Lord Dionysos led the charge, with his cadre of brother Sorcerers and mass of thoughtless, obedient Rubicon brethren, they lead the masses of Reliquary cultists, a menagerie of twisted mutants, rogue psykers and heretics among them out into the light and across the Hive. Their attack was so sudden, precise, and unexpected that the Imperial administration had barely any time to coordinate a defence, pitiful as it was. The planetary governor was sacrificed publicly within three weeks of the initial assault and the planet was mostly subdued within a few months, thanks to The Thousand Sons, and the rapid conversion of many people over to the Reliquary in the face of the swift destruction of the Imperium's forces. 

Their uprising turned out to be even more fortuitous, for shortly after Sagarius fell, the Emperor of Mankind was assassinated by radical Inquisitors. The news itself hit the planets in a psychic wave as a new God was born out of the physical death of such a mighty psyker whom had had uncountable trillions of souls sacrificed to him over millennia. Such a shockwave of raw power burnt out hundreds, if not thousands of psykers within the swelled ranks of the Reliquary's forces, even killing several of the Thousand Sons' own Sorcerers, though most of theirs were able to ride out the storm through their greater skill at protecting themselves. Lord Dionysos himself was indisposed for a couple months as his mind recovered, several last revelations apparently being given to him by Tzeentch before the God's attention turned to deal with the new player in the Great Game, but that didn't mean the Reliquary was idle. For Dionysos, along with his cadre of Sorcerers and the Grandmaster of the Reliquary knew that if they were suffering from the psychic backlash, then the Imperium was suffering even more. 

Thus, they took control of what ships they could obtain and struck the nearby worlds within the system in a blitz of mutated followers and fanatical heretics. The fighting was intense and lasted over four years, but as more sorcerers and psykers rejoined the fighting, the war swiftly turned over to the Thousand Sons and the Reliquary's forces, while the Imperials, despairing at the loss of their capital, communications beyond the system, and dealing with anarchy within its own streets simply fought as valiantly as they could. With the last visible fronts of resistance in the system quelled, the Reliquary and the Thousand Sons set about turning the worlds to the purpose of Tzeentch's worship, where billions of devotees praised him and conducted rites in his honour. Psykers were given free reign to do as they wished, mutants of all kinds filled the streets, and the entire planets were set to the task of preparing for the next phase of their plans. New artifacts and texts awaited in the worlds beyond their system, waiting to be turned back to the service of Tzeentch and his followers, and the Thousand Sons yearned to make carve out their place again in this time of change in the galaxy.
