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 XVth 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 other Human 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 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 surpassing them in every regard. The primarch turned from pupil to master.
