I was at the singing in Portland and I asked a question that got an RAFO. I just re-read Elantris and my question was related to something I picked up knowing more about the Cosmere now.
Q: When Elantrians want to die they go into the Shardpool. Are they unintentionally or intentionally world hopping somewhere? Also have we seen them in any of the books yet?
A: I'm surprised that no one has asked me that yet. (with a sly smile)
So maybe we can expect to see the Elantrans somewhere out there in the Cosmere in the future.
