The Night Stalkers are a warband of Chaos Space Marines of unknown origin and allegiance. These shadowy warriors hail from the lightless, daemon-infested night world of Cthonis Ultra. They are masters of ambush, often seeming to appear from nowhere when confronting their foes.
The Night Stalkers wear grey-coloured Power Armour with a purplish tint and gold trim. (Note: The Night Stalkers appear to have the same colour scheme as the Damned Company of Lord Caustos. Whether or not they have a connection to this other warband of Chaos Space Marines is unknown.)
The Night Stalkers do not have their own warband iconography, instead opting to wear the usual heretical Chaos markings and blasphemous iconography to denote their allegiance to the Dark Gods.
