Does Harmony have any Splinters?
Brandon Sanderson
(paraphrased)
Do you mean like in his fingers? *Brandon has a coy smile. Questioner looks at him like "you know what I mean you fool". Brandon laughs.* No, he does not have Splinters right now. Good question.

Will we see all of the Heralds doing things in the upcoming books?
Brandon Sanderson
(paraphrased)
The back five books are all about the Heralds. Two of them claim to be Heralds... Two of the point-of-views will be Heralds.

On a similar note, since Elsecallers can physically go to Shadesmar and have access to Transportation surge, can all Elsecallers worldhop?
Brandon Sanderson
(paraphrased)
Yes, that is one of the Elsecaller powers.
Ruro272
(paraphrased)
In hindsight this seems like a really obvious question now *laugh*, but I think it's really interesting that Elsecallers can travel to other planets too--we didn't know that before.
Brandon Sanderson
(paraphrased)
There are hints in the names on the map of Shadesmar.

Alright, but would nicrosil be the right metal to make a Hemalurgic spike if you did want to steal powers from another world?
Brandon Sanderson
(paraphrased)
It's a good theory, you're theorizing well.
Ruro272
(paraphrased)
Does Hoid have a Hemalurgically charged Nicrosil spike?
Brandon Sanderson
(paraphrased)
It's... unlikely. Hoid would not want to open himself to the influence of Shards so using Hemalurgy on himself is unlikely. Although Hemalurgy is the easiest way to get other powers, he'd more likely do things the hard way.

Is there a reason why shadows go toward the light in Shadesmar, or is it just worldbuilding flavor?
Brandon Sanderson
(paraphrased)
There is a reason, but its not super important. It's like a cultural thing, things have reasons but they aren't always super relevant to the story.

Is Roshar, or has Roshar always been the only large landmass on the planet?
Brandon Sanderson
(paraphrased)
Roshar is.... *Brandon then paused and looked up, thinking very hard* Roshar has always been the largest landmass--as long as there has been land.
Ruro272
(paraphrased)
Is there a separate "Shadesmar" for each planet or is it one big place that are all connected with different regions for each planet?
Brandon Sanderson
(paraphrased)
It's one big place with different sections.
Ruro272
(paraphrased)
So since its one big place, could spren travel to a different section that correlates with a different planet, such as the cognitive segment for Scadrial?
Brandon Sanderson
(paraphrased)
They could go there, but they wouldn't usually...
Ruro272
(paraphrased)
Is that because Honor's influence is only on Roshar?
Brandon Sanderson
(paraphrased)
*Brandon gave sort of a noncommittal half nod, but looked doubtful himself. Maybe best to interpret this last answer as a RAFO rather than reading into it too much.*

Was Adolin's murder of Sadeas him falling under the influence of Odium, or was that all him?
Brandon Sanderson
(paraphrased)
That was all Adolin.

Is there any sort of civilization on Braize?
Brandon Sanderson
(paraphrased)
Braize is the weirdest one because it's kind of like a prison. So, is there any civilization on Braize? Kind of. It's like a prison. That's all I'll say.

Any hint on how Nin got a hold of Nightblood, or how Vasher lost Nightblood?
Brandon Sanderson (Written)
(paraphrased)
Vasher and Nightblood had something of a falling out...
