Brotherhood of a Thousand Chapter Colour Scheme

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

Chapter Appearance

Chapter Colours

The Brotherhood of a Thousand primarily wears grey Power Armour. The Aquila or Imperialis is golden. The white squad specialty symbol on the right shoulder guard designates operational specialty -- Tactical, Devastator, Assault or Veteran. A black Roman numeral is stenciled on the centre of the squad specialty symbol which indicates squad number. The colour of the shoulder plate trim indicates company number in accordance with the dictates of the Codex Astartes -- White (1st Company), Yellow (2nd Company), Red (3rd Company), Green (4th Company), etc.

Chapter Badge

The Brotherhood of a Thousand's Chapter badge is a black letter "M" on a slightly undersized white roundlet, centred on a field of grey. The Latin numeral "M" represents the number 1,000.


Originally the letter "M" was the Great Crusade-era Legion badge of the Thousand Sons Traitor Legion, before being reunited with its Primarch Magnus the Red. After Magnus took command of the Legion the badge was changed to a stylised sun of eight sharp, serpentine points, before eventually becoming the mystical icon known as the Ouroboros (a snake eating its own tail), after the events of the Horus Heresy.
