The Knights of Dorn is a Codex Astartes-compliant Loyalist Space Marine Chapter of unknown Founding. It was created from the gene-seed of the Imperial Fists. Almost nothing is known about this Chapter in current Imperial records.
The Knights of Dorn wear a unique halved-heraldry of dark brown and bone white, painted in two halves on their Power Armour. Individual honour markings are painted on the right knee plate. The helm is unique in that beside its halved heraldry, the right eye lense is green while the left one is red. The bone white squad specialty symbol -- Tactical, Devastator, Assault or Veteran -- is located on the right shoulder plate. A black Roman numeral is stenciled in the centre of the squad specialty symbol, indicating squad number. The colour of 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), Green (4th Company), etc.
The Knights of Dorn's Chapter badge is an ebon skull within a white roundel outlined in black. This roundel is centred on a field of bone white.
