Thousand Sons - Specialist Formations: Rehati War Sect - Magisterial, masterful and unparalleled in psychic supremacy, the royal court of Magnus floats ethereally across the land. None can match this assemblage's prowess in the arcane arts, for the patronage of a Daemon Primarch confers power of such magnitude that the laws of physics are reduced to mere playthings. Named the Rehati in remembrance of Magnus' original bodyguard, this collection of psykers is comprised of the most favoured entities from the Planet of Sorcerers. Some may be warrior mystics from the Primarch's original Legion, others ascendant glory-seekers that have achieved immortality by becoming Daemon Princes of Tzeentch under Magnus' rule. The air shimmers with raw Warp energy as the sect advances, the deaths of their enemies assured by the dominating malice of the Rehati and their master.War Coven - For the sorcerers of the Thousand Sons, open battle is a chance to revel in the power they have marshalled over long millennia. War Covens, however, have a greater purpose than the gratifying thrill of magical potency. There are spells that can only be wrought when the tang of spilt blood is in the air and the screams of the dying echo in every ear, just as some magic is empowered by the passage of souls into the Warp. When a luminary of the Thousand Sons musters his kin in the seething cauldron of battle, the fabric of destiny can be undone and shaped anew. Such gatherings are treated with a wary respect even by the Grand Masters of the Grey Knights, for the War Covens are immensely dangerous in their pursuit of arcane secrets and the favour of their patron that it represents.War Cabal - An army of warrior mages and eldritch automatons, a War Cabal fights not only on the material plane, but also in the dimensions of the mind. These hosts are twisted reflections of Prospero's once-great Legion, which brought order to Humanity and the bedlam of battle to empires of aliens and fiends. Now, the War Cabals march against the very civilisations they once protected. The Rubric Marines and Scarab Occult Terminators advance relentlessly, their salvoes of hellfire burning enemy infantry to glittering ash. Amongst them chant the psykers who condemned the Thousand Sons to their twilight existence, their scholarly intellects turned from enlightenment to destruction. Those unlucky or foolish enough to resist them find their minds assailed, ripped apart by invisible claws even as their bodies are blasted asunder.Sekhmet Conclave - The Sekhmet Conclave is a concentration of magical force like no other. The air around these timeless warriors shimmers with Warp energy as the sigil-wards of the Scarab Occult Terminators magnify their protective powers to new heights. Gathered around their psyker masters, these massively armoured warriors walk in thudding lockstep, the beat of their heavy tread a deathly drum that speaks of impending doom. Inferno Combi-Bolters are raised at a silent command, a blistering slavo of bolts hammering out to send transmorphic flame billowing in all directions. The arcane syllables uttered by their lords echo across the battlefield -- though the Scarab Occult Terminators were once counted amongst the most powerful mortals in existence, their independence is long gone, and now they serve only the sorcerous fiends in their midst.Tzaangor Warherd - A Tzaangor Warherd is comprised of mutated Beastmen who loyally serve their sorcerer master tirelessly. Some of these fell creatures have even fallen to a cursed spawn-change in the process, becoming bestial in mind as well as body. Tzaangor Warherds are given the spoils of the corpse-harvest -- cadavers to make into grotesque puppets, body parts for the stewing of vile witch's brews, and sparkling jewels with which to adorn their jutting horns and feathered anatomies. Avarice glints in every eye of the Tzaangor Warherd as they lope into a howling, shrieking sprint, tearing those apart who would be foolish enough to stand against them, and are later made into trophies by day's end.Ahriman's Exiles - After casting the great Rubric that damned his Legion, Ahriman and his psyker elite were banished from the Planet of Sorcerers. Long did these warrior mystics roam the galaxy in search of knowledge, power and redemption. Now, Ahriman has united those of the cabal that are still alive, calling upon remnants of fealty and lingering traces of brotherhood to better cast down their mutual enemies. Where the Exiles walk, long-harboured ambitions of vengeance are made real. The air around this sorcerous brotherhood seethes with bitterness and hatred, an aura of menace so strong it saps the will to resist from those mortal souls nearby. To embrace the act of vengeance is intoxicating, and each sorcerer tries to outdo his fellows with the scale of his arcane attacks.
