The Atramentar were once the elite bodyguards of the VIIIth legion, they swore to protect their primarch and the night lords. They are men of honor and conviction, for what it means to the Night Lords, earning them the specialized terminator armor. Now 100 centuries later the Atramentar hunt for revenge and justice, against the imperium. (This is still a work in progress, more will be updated and changed as time goes on.)
