The Prism of Fate are a Chaos Space Marine warband of the Thousand Sons Traitor Legion. They once ensured that adherents from each of the sorcerous cults of Prospero could be counted amongst their number, the better to steer their brotherhoods through whatever challenges their Primarch, and their Emperor, should ask of them. Since the devastation of the Horus Heresy, the Prism's sorcerers have focused ever more obsessively on the diversity of deaths they can inflict upon their foes. The warband's sorcerers take pride in never slaying one victim in the same way as another -- their longevity is such that imagination is counted the most kingly of virtues.
The Prism of Fate warband's colours are teal with golden trim. The Magister Templi Nonyc Teheterys also wears the yellow of Tzeentch, the Changer Supreme. White, being the colour created when all colours join as one, is a favoured hue amongst the Prism's sorcerers. Employing a great many Rubricae, the patterns and symbols on their tabards mark them apart in a system that is incredibly complex despite its monochromatic basis. Seen in the Astral Plane of the Immaterium, these hues burst into a riot of colour that is painful to behold for those psykers not blessed by the Great Architect. Those few Rubricae aware enough to deliver inventive deaths are permitted to wear the yellow of the Changer.
Warband Badge Edit
Like the icons of many thrallbands of the Thousand Sons, the Prism of Fate's sigil is based upon the symbol of Tzeentch himself -- though reversed, it is still mystically potent. This usually takes the form of a white Mark of Tzeentch on a teal background, or reversed, as a teal sigil on a white background.
