I'm sorry if I wasn't clear, but I haven't had time to go through @kenod's calculations and was basing that solely on calculations that I've done in the past, specifically with regards to the planet Sel. Also I didn't mean to imply that it couldn't be the radius (in fact I believe that I stated up front that it could be), only that I think it more likely that it is volume. Elantris spoilers:

Careful here, it actually says that the size is 0.9, and size is an ambiguous term. It could mean radius (and I've in fact based calculations on that assumption in the past since it's convenient ), but it could also mean volume, or even mass. To be honest, I actually think that the most likely meaning is volume since: 1) it's what's most commonly meant by size, and 2) it leads to the most realistic numbers, at least in the calculations that I've done.

Why was Preservation worried? Because he sacrificed most of his mind to imprison Ruin, thus he could no longer remember his plan or what his predictions of the future were. He remembered that he had a plan, but not the specifics of it. He simply had to hope that it was good enough to work without him and to withstand Ruin's potential interference.

This theory that the expanses are defined by the location of the world is extremely interesting to me, partly because I'd never considered it until now. Given the movement of the bodies involved, I can really only see it working in a relativistic model: the locations remain in place with space itself moving past them, otherwise the magics would be constantly changing. Considering @Pagerunner's brilliant comparison earlier to Haemalurgy, I can't help but think of that WoB about the blood being in motion in part providing the link to the Spiritual Realm. The similarity between the two is eerie. Until now I've also been thinking of it in terms of the planet's Spiritual aspect defining this, but this is seriously elegant. I'm really going to have to think about this some more when I'm less tired.

Fair enough. Annoyingly I must have missed that WoB then. Anyway, thanks for the clarification.

Are you thinking of this WoB? Because that doesn't say "next book", it says "future book" which could just as easily mean book 10 as book 3 (though granted I'd expect to see it far sooner than book 10).

That's interesting, since that seems to contradict, if only by implication, this more recent WoB:

If you're looking for somewhere that isn't a planet, there's always Silverlight. Actually forgery does use a lot of Investiture: I'm pretty sure that we've already seen this. Just reread Vasher's Interlude from Words of Radiance: he's aware of both Kaladin and Syl before he otherwise could be.

On the plus side though, Unfettered II was a finalist. Clearly a result of the inclusion of The Thrill (or at least that's what I'll be telling myself).

I've searched WoK and WoR and that seems to be the only reference to it in either book (unless you count its placement on the map). I haven't searched Edgedancer because I don't have the ebook, but I don't remember it being mentioned in there. Additionally I can find no WoBs on it: I've done a quick search of theoryland, reddit, and twitter, as well as these forums, and haven't been able to turn up anything. Thus the coppermind article does seem to be complete (as it in fact claims to be at the bottom of the page). In short, we know it exists, we know where it is, we know that there are stories told about it, and that is all we know about it.

It hasn't been hinted at, it's been openly stated. source source source source This does not mean that Harmony is trying to influence events. Consider the Seventeenth Shard: they're sending agents to worlds, yet they have an explicit non-intervention policy. You can attempt to study a place without interfering. Thus I do not consider this evidence for Harmony intervening in other worlds' affairs. The red haze is evidence of something else interfering on Scadrial, not vice versa. I think what I say above address the rest of your comment.

I'm sorry, but how do we know that Harmony has been influencing events on other worlds? This is the first I've heard of this.

Rust and Ruin, you're right; I was so focused on the dragon part I didn't notice the Frost part. So much for reading comprehension I guess. Maybe I can blame this on my dyslexia? I think it's all but guaranteed that the recipient is Frost at this point though: they're both dragons, they both know Hoid, and they both have a non-intervention policy. There can't be all that many people going around who match all of those criteria. In terms of explicit confirmation though, I'm not actually sure that there is any. This is the closest that I could find:

Do you have a source for that WoB? I've done a quick search and haven't found anything. I vaguely recall Brandon maybe RAFOing it a while back, but it's so vague I'm not sure that I'm not making it up.

It has been confirmed. Source, comment #46 by Ciella. I'm pretty sure I've seen it somewhere else as well, but I can't remember where.

Here you go:

I agree. This in fact reminds me of that typo from Hero of Ages where Adonalsium was misspelled as "Adonasium", which to my mind sounds even closer to Adonai (though granted I don't speak Hebrew, and have no real idea how it should be pronounced).

Try telling that to Vasher, he seems to be managing quite well. Seriously though, what makes you think that there's no way worldhop from Nalthis?

Actually it's Era 4 that involves space travel; Era 3 will be a roughly 1980s tech level urban fantasy type setting. As for you main point, it is highly likely. The only other real contenders for the Ones Above are the Selish, the Nalthians and the Rosharans. The Rosharans are perhaps the next most likely contender since we know that Dusk has eaten Herdazian food.

I'm sorry, but I think you misunderstood me. I've just spent a little time rereading this to try and determine how, but apologies in advance if it turns out that I'm misinterpreting what you're saying instead. I wasn't trying to say that Syl did not change, she obviously can and did. I was responding to the first part of your original post where you claimed that Nale's blade transformed into an axe; I quoted the relevant section of Edgedancer to demonstrate that this isn't what the text indicates. My intent was to indicate that since the blade didn't change, there was no issue with the blade being an Honourblade. Edit: Sorry @Nomial, I didn't see your edit until posting and refreshing the page.

The point that I was trying to make here was that Helaran didn't give away his Shards as part of a scheme to fake his death: that would have been incredibly stupid, not least because it's generally unknown that he has them. Regardless, I don't think that what you said necessarily conflicts with what I did. It's quite clear that the Shardbearer wasn't a simple member of the opposing army and that he was targeting Amaram as an assassin, likely due to Amaram's association with the Sons of Honour. Why could this assassin not be connected to Helaran? Helaran is clearly involved in something after all: if he gave them to a friend like I proposed, is it not reasonable to think that the friend might not also be involved in something?

I don't think he did get it back given this WoB: Brandon definitely makes it sound like it's still missing. I guess he's just got a fake spike there (like what Wayne used when disguising himself as Marsh) to hide the massive hole through his head.

I believe that it's because Brandon doesn't want the Earth to be in the cosmere, not even a weird alternate version of it. He originally planned it to be cosmere, but then decided to make it it's own thing.

It is not an aviar.

Oh wait, do you have it as part of Arcanum Unbounded? I didn't even think to look it in there since I have the ebook (which doesn't have that page), but I've got it in front of me now. If I'd noticed the above comment which said that it's the same as the symbol for part 6 I wouldn't have had to waste time by asking about it. Anyway, as @Eki said, that one's Harmonium.
