Dark Brotherhood Astartes

Dark Brotherhood Chapter Colour Scheme

The Dark Brotherhood is a Codex Astartes-compliant Loyalist Space Marine Chapter of unknown Founding and origin. Almost nothing is known about this Chapter in Imperial records.

Chapter Appearance

Chapter Colours

The Dark Brotherhood primarily wears slate grey Power Armour. The white squad specialty symbol (Tactical, Assault, Devastator or Veteran) is indicated on the right shoulder pauldron. A red Roman numeral centred on the squad specialty symbol indicates squad number. The wings of the Aquila or Imperialis on the chest guard, as well as the backpack, are black. Most unusual, the colour of the skull on the Aquila or Imperialis on the chest guard indicates company number in accordance with the Codex Astartes -- i.e. White (1st Company), Yellow (2nd Company), Red (3rd Company), etc.

Chapter Badge

The Dark Brotherood's Chapter badge is a white Maltese Cross, with a large red skull centred on it, on a field of slate grey.
