This is the livery of the Death Whispers from the
Oldest Heresy campaign
the Illustration depicts the generic appearance of the marines with variations by speciality not shown & it should be noted that only the honour company who are all form the Grey Angels wear this at the moment. None of the actual Death Whispers have reached the stage of Scouts yet a process which has been slowed by the need to replace the Neophytes lost to the Necrons.
The chapter symbol is a winged skull in gold on the right shoulder over the words
"even the emperors whispers are death to his foes" the Honour company all wear the terminators cross on the left shoulder thought it is expected that the Death whispers proper will use proper codex iconography as one would expect from an Ultramarine Successor chapter.
