Night Walkers

A codex compliant Space Marine Chapter of unknown foundation and progenitor based on Morrowdim, a world of the Hadronian Wall, Aliris Sector.

Founding
There is no record of the establishment of this Chapter but they have been in existence at least since the 32nd millenium. Some theorize that the Night Walkers are descended from Loyalist Night Lords, certainly they nurse a deep enmity towards that particular Traitor Legion.

The Second Black Crusade (597.M32)
The earliest surviving records of the Night Walker chapter dates to this, the Traitor Legions' second assault on the Imperium. The Night Walkers are listed among the Space Marine Chapters who counter-attacked into the Eye - and returned. At the conclusion of the Black Crusade (c. 600.M32) the Night Walkers established themselves on Morrowdim, having apparently lacked a homeworld until then.

Current state of the Chapter
The Night Walker's Homeworld, Morrowdim, is listed in catalogues as Umbricus II the sole habitable satellite of a Brown Dwarf-star. Both Morrowdim and Umbricus are orbited by numerous smaller moons and planetoids known as the 'Hundred Moons' though there are actually only 51 moon sized satellites the others being captured asteroids. Many of these are inhabited.

The Night Walkers' Fortress Monastery is called the Fortress of Dreadful Night located on the hill above Morrowdim's chief settlement which is built over and into a slightly lower hill. Dispite the Fortresses' intimidating name the mortal inhabitants of Morrowdim are in and out of it all 'day' presenting petitions, bringing tithes or to see one of the Marines

Gene-seed
The Night Walkers suffer from two mutations in their gene-seed; one is moderately inconvenient. The other more unsettling to outsiders then the Walkers themselves. The first is a flaw in the occulobe. While the Walkers' eyes are duly sensitized to low light conditions they are unable to adjust for full light - which goes far to explain their choice of homeworld and habit of wearing their helmets,equipped with specially polarized visual units, at all times off it. Another reason for the helmets is their volume controlled vox units as, thanks to their second flaw, the Walkers speak in sepulchular whisper that almost everybody finds disturbing. Nor does upping the volume help much. It is suspected that both mutations are the result of trying to eliminate signature traits of the Night Lords; infrared sight and terror cry.
