LEGION XV THOUSAND SONS
Traitor Legion
The Thousand Sons are one of the Traitor Legions of Chaos Space Marines who are sworn solely to the service of Tzeentch, the Chaos God of Change, Intrigue and Sorcery, though they were once the Imperium of Man's XV Legion of Space Marines.
Primarch Magnus the Red
Magnus the Red, the Primarch of the Thousand Sons Traitor Legion, is one of the few surviving Primarchs and is currently an extremely powerful Daemon Prince of the Chaos God Tzeentch. He was also known during the early years of the Imperium as the "Crimson King" and the "Red Cyclops." A giant in both physical and mental terms whilst still an inhabitant of the Materium, the copper-skinned Magnus possessed tremendous innate psychic ability, and constantly sought to understand the nature of the Warp, becoming a Sorcerer of formidable power.
Magnus thought he would be able to control the Great Ocean of psychic energy that was the Warp; however, his prodigious and careless application of his psychic gifts eventually caused him to fall out of favour with his father, the Emperor of Mankind, as well as with the majority of his brother Primarchs. His psychic immaturity, recklessness, and arrogance also caused his own undoing, as it eventually brought about his own damnation and eternal servitude to the Dark God of Change, Tzeentch.
n the end, Magnus lead his XVth Legion to the banner of Horus and fought on the Arch-Heretic's side during the Great Betrayal of the Horus Heresy. He survived those events and ascended to the position of a Daemon Prince of Tzeentch as a reward for his service to the Changer of Ways. He has spent the majority of the ten millennia since the end of the Horus Heresy ensconced atop his tower upon the Planet of the Sorcerers within the Eye of Terror, planning the ultimate destruction of the Imperium he believes betrayed him and his Legion. Magnus' greatest grudge, however, is with the Space Marines of the Space Wolves, who he holds accountable for the destruction of his homeworld of Prospero and the corruption of his Legion during the early days of the Horus Heresy.
The Legion
Warcry
"All is Dust!"
The Thousand Sons are one of the Traitor Legions of Chaos Space Marines who are sworn solely to the service of Tzeentch, the Chaos God of Change, Intrigue and Sorcery, though they were once the Imperium of Man's XV Legion of Space Marines.
The main feature that distinguishes the Thousand Sons from the other Traitor Legions is the sheer number of psyker mutations that have always existed amongst the Space Marines in this Legion. Every current member of the Legion possesses psychic abilities and they prefer to use Chaos Sorcerers and guile in combat, relying on their psychic powers and sorcerous knowledge to earn them victory. As a result of an ancient spell known as the Rubric of Ahriman that was cast soon after the Thousand Sons fell from their homeworld of Prospero during the early days of the Horus Heresy, every Thousand Sons Astartes that lacked psychic powers had his soul fused directly into his Power Armour. The Thousand Sons have become living embodiments of sorcery animated by the power of Chaos and the will of the Lord of Change.
The Thousand Sons are the scions of the Primarch Magnus the Red, the copper-skinned cyclops whose thirst for knowledge in all its forms led ultimately to damnation and an eternity of servitude to Tzeentch, the Chaos God known as the Changer of the Ways. When the Primarchs were scattered throughout the galaxy, Magnus found himself coming to rest upon the distant, isolated colony world of Prospero. It was perhaps fortunate that a being that many societies would have denounced as a mutant came to such a place. Prospero's only inhabitants were a population of outcast scholars and mystics, who had long since fled the galaxy at large to establish a refuge where they could practise the arts of the psyker.
Raised by such scholars, Magnus learned and mastered every one of their arts, soon s urpassing them in every regard. The Primarch turned from pupil to master, his fearsomely powerful mind able to manipulate the raw power of the Warp in ways no others could. By the time the Emperor located His long lost son, Magnus was privy to every secret the libraries of Prospero could offer. He yearned to learn more, and in his sire found the only being with more psychic potential than he. Accepting command of the Space Marine Legion created using his own gene-stock, Magnus took his place in the Great Crusade, and utilised his puissant skills for the good of all Mankind
