Editing Thousand Sons (section)

===Post-Heresy===
After the Rubric of Ahriman, Magnus replaced the Legion's Nine Fellowships with Nine Cults. Each of them specializing in a facet of Tzeentch. while these cults may wax and wane in power, there are always nine.

At the top of the Legion is Magnus the Red and his Rehati. Each of the Rehati is a Magister Templi, and one of the most powerful and favored Daemon Princes or Exalted Sorcerers in the legion. At the head of each Cult is a Magister Templi and his coven of nine powerful Exalted Sorcerers or Daemon Princes, who help him run the Cult. These Cults are a gathering of unnumbered Sects that are lead by Sorcerers, who, whilst inherently self-serving, are nonetheless working towards the same common purpose.

*'''Cult of Prophecy:''' These guys are guided by the incessant whispers that bleed from the warp. They divine the outcomes of multiple futures, and seek out events that can be twisted to their own purpose.
*'''Cult of Time:''' They view the flow of time as an unwrought resource that can be shaped into a weapon. By their victories, ripples are sent both forwards and backwards in time, so that their enemies may be defeated before they are even engaged. One particularly cool example of a Time Sorcerer is when a squad of Imperial Fists were [[Troll|forced to relive the same events over and over until all of them died]].
*'''Cult of Mutation:''' They embrace the warping of flesh, and also the warping of reality itself. By their hand civilised planets are transformed into Daemon worlds, and entire populations moulded into grotesque abominations and various assorted gribblies.
*'''Cult of Scheming:''' To them, the creation of convoluted plots is to them a form of profane worship. Every conquest and withdrawal is a perfectly planned manoeuvre, a single step that leads towards some unseen master stroke. Naturally, the phrase [[Just As Planned]] applies most naturally to these guys.
*'''Cult of Magic:''' Dedicated to the pure and unfettered use of sorcery, their bloody campaigns are launched to secure arcane objects held by Imperial, xenos and other Chaos forces, making them part Tomb Raider part Space Wizard. These artefacts are used as foci in the weaving of devastating spells.
*'''Cult of Knowledge:''' These guys are drawn to the myriad curiosities hidden throughout the galaxy, particularly tomes of eldritch learnings, dark secrets and paradoxical logics. Through such lore, the cult is able to extrapolate the weaknesses in their enemies, and in the fabric of reality itself.
*'''Cult of Change:''' Anathema to order. They are the great unravellers, launching their armies wherever civilisation and reason exist. Similarly, in places of utter anarchy, the cult appears to impose their ever-shifting will. The most chaotic of the bunch, tied with the Cult of Mutation.
*'''Cult of Duplicity:''' Is a unique within the Legion in that it both is and is not guided by a unified desire. The Sorcerers of this cult are by their very nature deceivers, at once appearing fractured and singular in their purpose. As such, it is impossible to know whether the sects within the cult are acting independently or as part of a singular, terrifying plan.
*'''Cult of Manipulation:''' Using its tendrillar web of influence to sway the actions of its enemies. Vast networks of mortal and daemonic spies allow the cult to oversee their plots as they unfold through assassination, possession and the wreaking of pure havoc. Easily some of the most dickish.

Consisting of multiple Thrallbands, each Sect is lead by an Arch Magister who's an Exalted Sorcerer or a Daemon Prince with his Retinue, Familiars and Bodyguards. They have their own color scheme that is assigned by their Arch Magister, to distinguish them from other Sects. Thrallbands consist of nine lesser Sorcerer Thralls under the command of a Magister, who is a Sorcerer, Exalted Sorcerer or Daemon Prince. Beneath the Magister and his favorite wizards are lesser thralls – Aspiring Sorcerers and Scarab Occult Sorcerers who direct the ranks of lifeless Rubricae and Scarab Occult Terminators. Thrallbands may go on their missions alone, or with other Thrallbands. Some Thrallbands may have been exiled from Sortiarius, or left to do their own thing. Regardless, they always work towards furthering the Cult's goals, whether they know it or not.

Not much detail is given as to how the Thousand Sons' armory of vehicles works post-rubric, beyond the fact that they ''do'' still have and use vehicles, old legion leftovers as well as new stuff they stole. It's probably safe to assume that it's all maintained and piloted either by human cultists or [[Beastmen (40k)#Tzaangors|Tzaangors]] these days with maybe a few leftover Rubric Tech<s>marines</s>nomancers.

Also, it should be reminded that they are still '''NEEEERDS''' to their core as, when or if there is a Chaos raid on a Imperial planet and the Thousand Sons are called, they only end up [[Rage|pissing off the local Cult leader]]. Why? Because rather than [[Chaos Space Marines|raping and pillaging like any good Chaos member]], the Thousand Sons just ends up visiting the [[Derp|local museum, library or private art collection for a sight-seeing tour.]] Also, rather than trying to overthrow or destabilise an Imperial world like most Chaos-affiliated factions, the Thousand Sons use their sponsored Cults to become [[This Guy|collectors of items and people they are interested in.]] This means that when summoned, these bookworms tend to simply leave with the [[Troll|Cult's artefacts and best sorcerous practitioners not long after]]. [[RAGE|Pissing off their allies even further]]. Hmmm...a small army of space geeks swooping down and being 'graciously gifted' with artifacts that is not theirs? [[Blood Ravens|Where have we heard this before?]]

[[Tl;dr]], they are one of the nicest factions of Chaos Space Marines, but Tzeentch-damn it are they unreliable.
