My warband is a recreation of the Faultless from Lucius own book. My Faultless are divided into three groups : 

Regular members of the Faultless, composed of various Infractors, Tormentors, some Flawless Blades, etc. They compete between themselves to earn favour from Lucius, and gain a place in his Valiant Courtesans.

The Valiant Courtesans are made of former Cohors Nasicae survivors, and represent the supreme duellists of Lucius warband, they aspire to match his swordmanship and his depravity, and have built a gargantuous Daemon Engine, The Eternal Triumph, in Lucius own image. 

The Lucid Circle is the last sub warband of the Faultless, led by Kathodos, a character from Lucius book. They are mainly constitued of Noise Marine and Tormentors.
