OK NO! I WAS JUST READING THE GUIDE ON CHAOS WARBANDS, and something caught my eye. APPARENTLY dark apostles can only originate and / or exist within (or be from) word bearer armies. Even though they could be chaplains from a renegade chapter NOPE APPARENTLY NOT!!!
I may be over-reacting but, but the painted model on the webstore is painted as an emperors children marine so why cant any legion get dark apostles.
I am going to have at least one dark apostle in any fanon warband I make because it makes sense for most AND IF YOU CLAIM THIS IS AGAINST CANON THEN LET TZEENCH HAVE MERCY ON YOUR SOUL!
