Night Lords - Specialist Ranks and Formations: The Night Lords Legion is organised into companies, each of which is led by a Captain, with each company composed of squads of ten Astartes called "Claws" led by a sergeant. There is also an elite Terminator unit known throughout the Legion as the "Atramentar", and at least one Dreadnought. When ready for combat, the Night Lords refer to themselves as "in midnight clad," reflecting both their heritage and their penchant for operations conducted under the cover of darkness.Kyroptera - The Kyroptera were the Night Haunter's most trusted advisors and confidants within the Night Lords Legion. Consisting of seven chosen Captains of the Legion, the Kyroptera existed outside the rest of the VIIIth Legion's regular command structure. Together the Kyroptera functioned as the soul of the Night Lords, supporting their Primarch and steering the Legion's temperament and decisions.Atramentar (Post-Heresy) - The Atramentar were the elite Terminators of the VIIIth Legion's formidable 1st Company led by the infamous First Captain Jago Sevetarion during the Great Crusade and the Horus Heresy. This elite cadre's numbers were chosen from amongst the standard ranks of the Night Lords Legion from Astartes who had been singled out and personally selected by their primarch for their ferocity and cruelty. Each member was known by name and reputation within and without the Night Lords Legion. Following the death of the Night Haunter at the hands of the Imperial Assassin M'Shen on Tsagualsa after the Heresy, the Atramentar scattered with the rest of the Legion and, by the time of the 41st Millennium, often served as bodyguards to the powerful Chaos Lords who commanded the various Night Lords warbands. While originally outfitted in Tartaros Pattern Terminator Armour, over the centuries many of the surviving Atramentar Chaos Terminators adapted other patterns of Terminator Armour captured from Loyalist Astartes as their own ancient armour was damaged or wore out with little chance for securing replacement parts.Raptors - Amongst the ranks of the Night Lords are the dreaded Chaos Space Marine assault troops known as Raptors. This elite group of egotistical and arrogant warriors believe themselves to be the betters amongst their allies and fellow Renegades. Many other Chaos Space Marines consider them to be preening, self-indulgent egotists. The origins of this particular specialty group can be traced to the bygone days of the Horus Heresy when they served in the important shock attack role of jump troops. At that time, Jump Packs were a comparatively rare technology amongst the Space Marine Legions, but such was the effectiveness of these assault troops that their commitment to battle often proved to be the turning point. Often times they were kept in reserve and then sent into action against the weakest points of the enemy line. This concept of preying on the vulnerable has led the Raptors to become vicious hunters who can strike anywhere, at any time. The Raptors have a tendency to modify their armour to give themselves a more terrifying appearance, mimicking the appearance of a vicious bird of prey or a swooping daemon. They often fit amplifiers and Voxcasters that emit piercing wails and screams to their helms, falling upon the enemy like a shrieking, furious gale, tearing their foes apart with Bolt Pistols and vicious Chainswords. In combat, the Night Lords always tend to deploy large numbers of Raptors.Unguis Raptus - A gift from his master, the Legion's First Captain Zso Sahaal, the "Talonmaster", incorporated the use of archaic Lightning Claws which he had named the Unguis Raptus -- the "Raptor's Claws" -- into his Power Armour and in so doing also coined the name of the command company for his 1st Company. Before the Horus Heresy (known to the Night Lords only as the "Great War") Zho Sahaal's Unguis Raptus company of Night Lords Raptors became justly feared by the VIIIth Legion's enemies. First in the name of the Emperor, and then for the Night Haunter alone, they brought swift death from above to their foes.
