|Brotherhood of a Thousand|
1000 Space Marines
Roboute Guilliman (Suspected)
Grey and Gold
The Brotherhood of a Thousand is a Codex Astartes-compliant Loyalist Space Marine Chapter of unknown origin and Founding, although the chapter believes they are descended from the Ultramarines. Almost nothing is known about them in Imperial records.
The Brotherhood of a Thousand believes that they are a Successor Chapter of the Ultramarines, but it is actually unknown who their Primarch is and from which Chapter's lineage they truly claim descent. Nothing else is known about them in Imperial records.
The Brotherhood of a Thousand primarily wears grey coloured Power Armour. The Aquila or Imperialis is gold in colour. The white coloured squad specialty symbol on the right shoulder guard designates operational specialty -- Tactical, Devastator, Assault or Veteran. A black coloured Roman numeral is stenciled on the centre of the squad specialty symbol which indicates squad number. The colour of the shoulder pad 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.
The Brotherhood of a Thousand's Chapter badge is a black coloured letter "M" on a slightly undersized white roundlet, centred on a field of grey. Their Chapter badge is the Latin numeral "M" for the number 1,000.
Originally the letter "M" was the Epic: Space Marine -- Great Crusade-era Legion badge of the Thousand Sons Traitor Legion, but this is no longer the case as their badge has been changed to the mystical icon, known as the Ouroboros (a snake eating its own tail).
