The Black Inculpators were created at some point after the Second Founding. In 2455.757.M40 they were one of the twenty Chapters contacted by the Adeptus Ministorum envoy Balthazar van Heppel, who wanted to write a report on the Space Marines' religious beliefs for the Ecclesiarch.
The Black Inculpators primarily wear black Power Armour. The Aquila or Imperialis on the chest guard is silver. A white, open-faced squad specialty symbol on the right shoulder pauldron designates squad type (Tactical, Assault, Devastator or Veteran). The white Roman numeral centred on the squad specialty symbol designates squad number. The colour of the shoulder plate trim indicates company number in accordance with the dictates of the Codex Astartes -- i.e. White (1st Company), Yellow (2nd Company), Red (3rd Company), Green (4th Company), etc.
The Black Inculpators' Chapter badge is a stylised white sword centred on a field of black with the tip pointed downwards. A five pointed star caps the sword's pommel at the top.
