There has been a LOT of MB3 speculation and debate over the past few weeks, and it's only a matter of time until those questions are answered. Thus, I thought as a fun game, we'd compile a list of questions that we hope are answered. We can then make a post with all those questions, and everyone can give (the briefest possible) answers to each of them. Then, once the book is out, we can compare scores and see who predicted the most (as well as hopefully get answers from Brandon on what wasn't answered).
So, I'll start with some questions I can think of, but please add ones you can. Try and word your questions in a way that they can be easily answered with just a few words or a sentence at the most. Maybe after a week or so we can compile them all and then have people 'vote'.
1) Who is the Hero of Ages?
2) Do inquisitors use allomancy?
3) Who is the Mist spirit?
4) What is the Deepness?
5) Why does the Mist kill?
6) What role do the Ashmounts play?
7) Is Reen's voice actually Ruin?
What was in the Well of Ascension?
9) Which character's die?
10) What are Koloss?
11) What are Kandra?
12) Where did Kell get the 11th metal?
13) Why can Vin draw upon the mist?
14) Why can Vin pierce copper clouds?
15) Where will the final battle take place?
That's all I can think of now, but I'm sure there are plenty. Please add your own, or if any of those aren't worthy point them out as well. I'll try and keep this post edited with a concrete list of questions people post.
