The Crimson Shades is a Loyalist Space Marine Chapter of unknown origin and Founding. Virtually nothing is currently known about this obscure Chapter within official Imperial records. The Librarians of the Crimson Shades, like their counterparts of the Space Wolves and the White Scars Chapters, are one of the noteworthy examples that take exception to the doctrines of the Codex Astartes. Though the role of this Chapter's Librarians is not so different from the traditional role found for Librarians in more orthodox Chapters, it is in the methods they employ that they differ significantly from the majority of the Adeptus Astartes. Exactly what this difference is has not yet been recorded.
The Crimson Shades primarily wear red Power Armour, which includes the helmet, torso, groin and legs. The power pack, shoulder plates and arms are white. The open-faced, red squad specialty symbol -- Tactical, Assault, Devastator or Veteran -- is indicated on the right shoulder plate. A red Roman numeral centred on the squad specialty symbol indicates squad number. The colour of the wings of the Aquila or Imperialis on the chest indicates company number in accordance with the Codex -- i.e. White (1st Company), Yellow (2nd Company), Red (3rd Company), etc.
The Crimson Shades' Chapter badge is a large, red human skull in the centre of a red, open-faced roundlet, surrounded by four lightning bolts, on a field of white.
