The Knights of Blood are a currently Renegade Space Marines Chapter who were declared renegades and Excommunicate Traitoris by the High Lords of Terra on the advice of the Inquisition because of the terrible destruction they wrought against friends and foes alike, yet the Knights of Blood still consider themselves to be loyal to the Emperor of Mankind, if not to his Imperium. The Knights of Blood are a Successor Chapter of the Blood Angels, created during an unknown Founding.
The Knights of Blood are considered by the military forces of the Imperium to be the epitome of a dedicated assault force. Those who have actually witnessed them in action report a Chapter consumed by savage butchery and carnage on an unparalleled scale. A Knights of Blood force in combat seeks nothing more than to come to grips with an enemy in close combat so they can rend them apart in a hail of blood with Chainswords and Power Fists and, if need be, their bare hands and teeth
