Where other fellowships pursue time, fire or fate, the adepts of the Cult of Mutation pursue the malleability of living matter, the domain in which their patron Tzeentch is most terribly expressed. To them, flesh is merely another substance to be reshaped by the will of a sufficiently learned sorcerer.
In battle their powers are grotesque and immediate. A whispered incantation may cause an enemy's bones to sprout and twist, his body erupting into a mass of tentacles and eyes, or reduce a squad of warriors to a heaving carpet of changed meat. They warp their own beast-thralls and daemon-things into ever more monstrous shapes, and some are rumoured to graft the essence of the warp into their creations, birthing horrors that should not exist.
The Cult holds a peculiar and dangerous fascination with the flesh-change, the very affliction that once ravaged the Thousand Sons and drove Ahriman to work the Rubric. Its adepts study the mutation not with dread but with scholarly hunger, believing that to master it is to master the deepest gift of their god. It is a perilous obsession, for the flesh-change respects no sorcerer's control, and many who sought to command it have themselves dissolved into screaming, mindless ruin, monuments to the fickle cruelty of Tzeentch.
Thousand Sons
Order of battle
The Cult of Mutation field the units of the Thousand Sons — a detachment from the roster:
Kindred formations
Other Thousand Sons formations
Cult of MagicThe Cult of Magic is the fellowship of raw arcane power, home to the most destructive battle-sorcerers the Thousand Sons can field. Where other Cults pursue subtlety and schemes, its adepts pursue the direct and overwhelming application of the warp, channelling storms of eldritch fire and bolts of unmaking that reduce armour, flesh and fortification alike to drifting ash. They are the burning heart of the Legion's armies, and where they walk the very air ignites with unleashed sorcery.
Cult of ProphecyThe Cult of Prophecy is the fellowship of seers and fate-readers, the eyes through which the Thousand Sons perceive the tangled futures of the galaxy. Its adepts divine the paths of destiny, unravelling omens and threading the Legion's centuries-long schemes through the chaos of what may come. In war they turn foresight to lethal advantage, anticipating every enemy stroke, and in the councils of their sorcerer-lords their visions shape campaigns waged across generations toward ends only they can see.
Cult of TimeThe Cult of Time is the fellowship of the Thousand Sons devoted to the manipulation of duration itself, the most disorienting and feared of the Legion's sorcerous disciplines. Its adepts perceive the flow of moments as a malleable current, hastening their allies to blinding speed, freezing enemies in the amber of a stolen instant, and glimpsing the many futures that branch from every action. To war against the Cult of Time is to fight an enemy that seems always to have moved first, striking before the blow is even conceived and vanishing before retribution can fall.
The Prodigal SonsThe Prodigal Sons are the warband of Ahzek Ahriman, a cabal of exiled sorcerers who followed him from the Planet of the Sorcerers in pursuit of forbidden knowledge. Cast out for the catastrophe of the Rubric, they wander the galaxy seeking the power to undo what he wrought.
