The Flawless Host is a Chaos Space Marine warband in the service of Slaanesh, and was once the 36th Grand Company of the Emperor's Children Traitor Legion, which did not retreat into the Eye of Terror like the rest of their Legion did at the end of the Horus Heresy but were forced back into realspace through Warp Storm Bloodfire. Autopsies conducted by the Tech-priests of the Adeptus Mechanicus on the corpses of slain Flawless Host warriors have confirmed that the Flawless Host uses an extreme amount of exotic combat stimulants in battle. Lead by the Slaaneshi Chaos Champion Eleaxus the Flawless, the Host has slowly grown a major force of Chaos Space Marines dedicated to the Prince of Pleasure, and they firmly believe, in line with the Emperor's Children's original conceptions of perfection, that all other Chaos Space Marines, including their former comrades amongst the Emperor's Children, are weak and that only the Flawless Host has truly achieved the perfection promised by Slaanesh.
The Flawless Host's Power Armour is painted pale pink. The right arm and shoulder plate, lower legs and backpack are painted ina purple flame-like pattern. The trim and warband insignia are painted black.
The Flawless Host warband's badge is similar to the sigil of the warband's patron Chaos God Slaanesh, except that the lower part is a crescent instead of an orb, and the other end is a six-pointed star.
Notable Flawless Host Chaos Marines
- Eleaxus the Flawless - Eleaxus is a devout Chaos Champion of the Pleasure God, and cares for nothing more than his own glorification and the furtherance of his desire to sit at the right hand of Slaanesh, damning himself further by partaking in blasphemous feasts after his victories. With the promise of all the luxuries of the Imperial world of Makenna VII, Eleaxus' fealty was bought by Warmaster Davroth of the Word Bearers Traitor Legion, to help him conquer the doomed world. He leads three elite squads of Emperor's Children Chaos Terminators known as The Scream of Hatred, as well as three squads of Emperor's Children Traitor Marines mounted on Rhino armoured transport carriers, who are known as the Choir of the Damned.
- Brother Jhasius (Chaos Dreadnought) - Jhasius is a former Battle-Brother of the Flawless Host who is now interred within the sarcophagus of a Chaos Dreadnought.
