The Flawless Host are consumed by a conviction that borders on madness: that they have transcended imperfection entirely. Every gesture is rehearsed, every strike delivered with sterile exactitude, every word measured for maximum effect. Their armour is kept in immaculate condition, and they view any blemish upon themselves or their works as an intolerable stain to be expunged.
This obsessive self-regard makes them singularly dangerous. Where other warbands surrender to frenzy, the Flawless Host remain glacially calm, dissecting their enemies with the detachment of surgeons. They believe that true perfection lies not in wild excess but in absolute control, and they hold their more decadent brethren in open disdain, considering them coarse and undisciplined.
Yet their perfection is a lie they tell themselves. Beneath the flawless veneer lies the same corruption that claimed the whole Legion, and their serenity is merely another mask worn by Slaanesh's chosen. Those who fight them speak of an eerie, mirror-smooth cruelty, a foe who kills without passion and admires its own handiwork without joy.
Emperor's Children
Order of battle
The The Flawless Host field the units of the Emperor's Children — a detachment from the roster:
Kindred formations
Other Emperor's Children formations
Cohors NasicaeThe Cohors Nasicae is the personal warband of Lucius the Eternal, a mercurial and ever-shifting host of Slaaneshi Heretic Astartes bound to the galaxy's most infamous swordsman. Its ranks swell and dwindle at their master's whim as he leads them from one exquisite bloodletting to the next, forever hunting the finest opponents the galaxy can offer.
The Kakophoni ChoirThe Kakophoni Choir are devotees of the sonic arts, warbands built around massed ranks of sound-weapon bearers who treat warfare as a grand and hideous concert. To them, the destruction wrought by their weapons is music, and each battle is a composition to be conducted with care. They seek out worlds famed for their acoustics or their populations, staging symphonies of annihilation for the pleasure of their god.
The Phoenix ConclaveThe Phoenix Conclave is a council of the mightiest Emperor's Children warlords, bound together by the Lord Commander Primus Eidolon in pursuit of a single obsession: the reunification of Fulgrim's shattered Legion and the return of their primarch to lead it. More a fragile alliance of predators than a true command, it endures only so long as its members' shared ambition outweighs their appetite for one another's ruin.
The ScourgedThe Scourged are among the most extreme of the Emperor's Children, warriors who have driven the pursuit of sensation so far that pain and pleasure have become indistinguishable to them. They mutilate themselves and their captives in elaborate rituals, wearing their scars as trophies and works of art. In battle they hurl themselves at the enemy with reckless abandon, hungry for the exquisite agony of the fray.
