User blog comment:Ynot0207/Horus Heresy Series v. Anthony Reynolds (Dark Apostle, Disciple, Creed)/@comment-81.105.173.193-20120618074439

I thought everyone knew that? The Horus Heresy novels are written around the year 30k, they are prequel novels detailing the Heresy and the creaton of the traitor marines. The 40k novels have been written for years before the heresy novels were being written. I advise don't read any other warhammer 40k novels until the Horus Heresy has been completed and you have read all of them otherwise you will continue thinking that these authors are SPOILING the ending of the Horus Heresy. If you google the likes of the Night Lords or any of the marine legions you will find out all about what happens to the primarchs and the legions because they were already written before the Horus Heresy.
