I have a question about the man at the end of Rhythm of War that Kaladin finds, that used to recollect lost objects from the Shattered Plains, such as Rock's razor or even Tien's horse. Will we get to know more about him, or is it just a random man?
So, what is happening there is all RAFO material. I'm not gonna answer any specifics about Tien's horse or even about Tien. There are lots of ways you can theorize that this happened, and I'm not gonna canonize which of them it is. One of those includes Hoid and his shenanigans, that's a possibility. One of which is kind of some Fortune being <around> what's going on. Other possibilities are that there's a divine manifestation. I'm not gonna say which of those it is, but there are lots of plausible answers there.
