The Silver Sons are a Chaos Space Marine warband that was formed by members of the Thousand Sons Traitor Legion who were exiled by their Primarch Magnus the Red for aiding in the disastrous sorcerous ritual called the Rubric of Ahriman. The Silver Sons covet certain priceless metals found within celestial objects, believing them to be links to the past and future. Once obtained, these metals are used in the creation of twisted Daemon Engines, and should such substances lie on inhabited worlds, the Silver Sons will incinerate all who stand between them and their prize.
The Silver Sons warband's colours are a dark blue with silver trim, not drastically different from their parent Legion. They are known to line their Power Armour with priceless metals that have been extracted from celestial objects. They believe this makes them one with the stars by bestowing upon them a measure of the cosmos' natural power. They wear sky blue tabards and robes.
The Silver Sons warband's badge is a stylised yellow sigil of the Cult of Time centred on a field of dark blue and trimmed in silver.
