Have you decided it'll be Rysn or Rock for the novella [between Oathbringer and Rhythm of War]?
Rysn for this one, Rock for the one between four and five.
Obviously not anytime soon since you have a busy schedule, but do you ever see yourself looping back to do a novella/short story between The Way of Kings and Words of Radiance? Maybe the Lopen story you mentioned? Or is it something that's not valuable now?
I do want to do this some day, for cohesion's sake. So I can see myself doing this. (Maybe in the stretch between Books Five and Six when I'm working on Mistborn Era Three?)
Do you imagine that this possible Lopen novella would be an evolution of the King Lopen the First of Alethkar short story you've mentioned? Or would they be completely distinct? Or do you just not plan on writing that short story anymore?
That's what I have in the back of mind, but I would have to seriously consider what I'm going to do once the time arrives.
