I think I am not alone in being baffled by the End Times plot, as someone who came to AoS after the Old World ended. I am trying to get a grasp for how the Chaos Dwarfs might be integrated into AoS without a retcon.
I have seen that orcs sacked the CD capital during the end times and that Gork/Mork defeated Hashut... but where was that written about in the official fluff?
I have also seen vague reference to current AoS fluff mentioning the Chaos Dwarfs. Does anyone know of an actual example of this?
