Yeah, at the end of False Gods when Horus is talking about his plans of "toppling the Emperor from his Throne" he says 'The Emperor commands the loyalty of millions of soldiers and hundred of thousands of Astartes warriors." Page 405 near the top middle. And I was thinking Ok..Horus has 10K, and Magnus is with him..so there's 20K..and 16 other legions makes 160K Astartes, which isn't hundred(s) of thousands. That's before he converts another 6-7 legions and I wasn't sure if he took into account that fact he was working on the Iron Warriors and some of the other legions he was planning on converting before he made the statement.
Yes, I know I'm looking to deeply into the words of the author. But I think the author has to be held responsible anything he writes that may or may not contridict the already written fluff. There will be people out there who hold the fluff as the Written Word, and anything that may challenge what is already Truth, will be scrutinized by many a loyal fan. Me? I just like the facts to add up, and don't care for descrephancies. (sp?)
