Just a funny thought, then I got to thinking Brandon is Hoid. The collector of stories. The one that was there for the shattering but not one of the shards. Who, Travels to all the worlds and interjects as only an author would (kinda like the neverending story). Whether it is written into the books at some point or not, the two are connected for me now.
What do you think?
Or is it deeper, in all actuality is Brandon Sanderson really a worldhopper? That's why his books are so good. It's just history, not fantasy.
