I think that we are agreeing lol I just wasn't as comfortable making such specific statements as I didn't have the quote's ready. You showed another good example of what I meant with the changes - perpendicularity - and definitely were able to say some things for certain that I did not know but I think in spirit we are saying the same thing.
I kind of figured the cannibalization to the mistborn gods but I didn't want to confuse anyone as I wasn't sure. Very interesting the thing about Darro though, and good to know about the magic system, I think that it had a lot of use beyond what we saw and the greater Cosmere implications are endless.
As far as speculation goes I wasn't saying not to speculate, I was just saying that with things like the gods being used elsewhere show that there is not much in this book to use towards theory crafting - other than Darro and the magic system - I never meant not to do it. My post was just to make clear that while Brandon has incredible foresight and when the books come out everything seems so perfect and planned out, he is making it up at he goes. While there is an outline it is subject to change, and often does, we just have to roll with the punches as they come, much like Brandon himself does.
Thanks for the info though I did not know all that.
