Aside from the Greater Roshar system, are there any other multiple shardworld systems?

Yes. You have not necessarily seen them though.

Does a more Investiture-poor world make it so its magics are easier to use off-world? Because, you said that Scadrial is really Investiture-poor, and it can be used easily off-world, but Roshar is very Investiture-rich, and how can you get Stormlight off of Roshar?

Yeah. Um, I would say that there is a correlation.

There is a correlation?

Mmhmm.

What differentiates a minor Shardworld like First of the Sun?

The amount of Investiture, and whether there is actually a Shard in presence.

Question

I'm assuming there is not one there?

Brandon Sanderson

There is not one there.

Question

So it's like a Splintered one from something else?

Brandon Sanderson

No what you'll find is that the worlds were all created with a level of-- a little bit of sort of ambient magic. What you'll find in worlds like that is things like, Shadows for Silence and things like this, the magic, it's not necessarily "people with magic" it's you can interact with nature...

Question

So there is inherent investiture...

Brandon Sanderson

There is inherent investiture in every world created but you are going to see-- You aren't going to find Mistborn on a world like that but what you might find is a way there are magic aspects to the setting. Spren could exist on a world like that but they would be like the minor spren, you wouldn't find Syl, but you would find something like lifespren.

Do you have other minor Shardworlds?

Yeah I have a bunch of them, and which ones are worth telling a story in will depend on when I get around to it whether they’re worth it.

Hey Brandon!

I'd like to open by thanking you for changing the method of Szeth's death. When I read it the first time, Kaladin's actions in that moment didn't ring quite true for how I saw the character. I'm glad Kal does what he does in the revisions.

I have three questions, if you wouldn't mind. I'm trying to avoid the obvious RAFO's xD

1. Threnody and Scadrial are both noted as having unusally bright patches of stars in their skies. Are these two planets near to one another?
2. Did Ashyn ever have a Shard, or is its magic a natural manifestation akin to Threnody or First of the Sun?
3. As you've stated that the magic of First of the Sun is natural and independent of any particular Shard, what is the nature of the pool on Patji? Is it also a natural manifestation of magic, a Perpendicularity, or simply a pool like any other?

Thanks for taking the time to answer these questions, Brandon. I know you've always got family stuff, and writing, and all the other host of things that fill up a life to do, so it means a lot that you take the time to interact with us fans. Thank you for sharing your stories with us.

1. They are both seeing the same thing, yes.
2. RAFO on Ashyn, as--being in the same system as Roshar--there are going to be some spoilers relating to Stormlight in anything I say here.
3. It's a natural manifestation, but on a much smaller scale than you might find on other worlds.

Regarding #1, does this mean that Threnody and Scadrial are part of the same system, or are these bright patches visible from other worlds as well?

Brandon Sanderson (Reddit)

Visible from other worlds as well. The cosmere is a relatively small place (on a galactic scale, that is.) We'll publish the star map when that becomes relevant in a decade or so.
