SpanReads: The Well of Ascension - Cosmere Implications

On the voice in Sazed's head telling him about the rings. Brandon said it was intended to be Kelsier, but later he realized the timeline doesn't work.

Did you pre-write the Kelsier stuff for Secret History, or did you just outline the events ahead of time?

Brandon Sanderson

Kelsier was notes, though detailed ones. They might mostly worked out. I believe there was one "thought" a character has in HERO that I had written to be influenced by Kelsier, but turned out to be logistically impossible. I worked on Secret History itself on and off for years before finishing it last fall.

Was that thought the one Sazed has in his fight with Marsh?

Those weren't coins, a voice seemed to whisper.

The bag Marsh shot at you. Those weren't coins.

Brandon Sanderson

Yup, that's it.

Moving the well, playing with where Kelsier was, and the physics of moving through perpendicularities between Realms all kind of combined to make what I had planned originally there not work. I tried fudging things so Kelsier could be there, and felt it was dishonest to the rules. So I didn't let him stray far enough from the Well to talk to Sazed there. Peter had thought for years that was Kelsier, I recall, and was sad we couldn't connect them.

I don't suppose you'd be willing to share with us who the new, canonical voice in Sazed's head is?

Brandon Sanderson

I'm afraid I probably won't ever go into this. At some point, you risk twisting and turning too much. I have a canon answer in my head, but for readers, it will probably need to remain ambiguous--with "it was simply him coming up with it on his own" being a valid option.
