persecutors of darkness

Hi new to all of this, bought the dark vengeance box set after years of not playing. Didnt really want to paint green so decided on an unforgiven chapter of the dark angels the "persecutors of darkness" I've gone for a dark red body with black shoulder pads green highlights and golden detail. Cannot seem to find much information about this chapter apart from some fan based stories. Struggling to decide on colour for my ravenwing and deathwing, contemplating a few schemes that will be brighter then usual due warp bleaching from residing so close to the warp and constantly fighting the horrors of chaos and on the verge of going Crazy due to constant chaos psychic attacks Any information on these guys would be much appreciated Will get some photos up soon
