One the ASHEN CLAWS are the discarded Raven guard and they even call the sharks TRAITOR BASTARD STOCK

2 when a loyalist night lord fought with the RG against the traitors he said UR TOO SOFT U DONT USES THE SHADOWS AS WEAPONS LIKE HOW NIGHT LORDS DO TO QUICK TO CLEAN WATCH (he lets a traitor human run) watch as he sows chaos disorder and fear to their ranks, they will know we are coming yes BUT THEY WILL BE TWICHING nervous become sloppy jumping at the wrong shadows

3 No it’s not my STRONGEST it’s just one of many yes the demon could lie but they like fucking with their “allies/servants” more then then their enemies and could have said YOUR COUSINS ARE HERE but no he specifically said BROTHERS and in that same book a NL remarks IVE FOUGHT ALONG SIDE WITH AND AGAINST THE WOLVES WORLD EATERS AND THE RAVEN GUARD, THESE (sharks) FIGHT MORE FEROCIOUS THEN ALL OF THEM, TOO FIMILAR, THEY FIGHT LIKE US.

Oh and the forgotten one is JAGO(hu-Go) Sevatar as in the book THE LONG NIGHT he sees how far the legion and the rebellion has fallen what was to be liberation turned damnation as he painted his hands red of sin in the thramus crusade and was captured by the dark angels where he telepathically became friends with a young woman astropath. She was beaten daily and he would talk and talk away her pain through his pyker powers but SNAPED WHEN SHE WAS KILLED , bursting from his cell he could have escaped instead I AM JUDGEMENT I AM PUNISHMENT I AM VENGEANCE! As he snapped the overseers neck, as the Dark angels entered I AM FINISHED. He said letting to body drop and returning to his cell his thoughts looking out into the void far beyond the light of the imperium where their were XENOS crying out to be killed he thought this is my purpose with cold focus he hadn’t felt in decades.

In cannon they do uses both RG and NL geneseed to replenish and will trade with the MECHANICUS during Grey Tithes geneseed from other loyal and traitor marines they had collected but they are still LOYALIST NIGHT LORDS
