Yes, that's Wit's flute. SA 5 preview chapters:

I'm of the opinion that Odium either wins, or will force Dalinar to break the terms of the contest and free himself from Roshar. Odium doesn't want to win, sure it's better than losing, but he will still stay chained by Honor if he wins. The best outcome he can get is to make Dalinar break the terms, as that would put Dalinar in Odium's hands. Dalinar's future isn't looking good, he will either be killed and turned into Fused, or experience Odium killing the Stormfather after he becomes free.

Melishi is the name of the only Bondsmith that was alive during the False Desolation, bonded with the Sibling. Here is his page on the Coppermind: https://coppermind.net/wiki/Melishi. The problem with this is that Melishi and the Sibling broke their bond before the imprisonment of BAM, he would be unable to open a perpendicularity without his powers. He might be able to use Cultivation's perpendicularity instead. Technically speaking Oathgates and Aon Tia (from Elantris) travel through SR, as in it distance doesn't matter, which allows for instantaneous travel. What if you open an Oathgate but sever the connection mid-transfer? Maybe you would get stuck in SR. I'm very intrigued to find out the answer.

As others said, it was the White Sand, but Hoid is a collector, he has a lot of stuff in his collection, some Hemalurgic spikes, even Atium. He definitely has some pure Dor as well.

Yes, a Vessel can influence the intent of a Shard and even change it to some extent. Different interpretations might create slightly different Shards, so different people would Ascend to different Shards. That's what Rayse tried to do with Odium, changing it into Passion. A Vessel filters how Shard's intent is expressed.

We already knew that the fight between Odium, Mercy and Ambition happened not on the planet Threnody, but in space, after which she fled. From this alone we can speculate with high certainty that she was Splintered not on any planet, but in the void of space, far away from any system and planet. AU Threnodite system: Probably the same thing that would happen to any Splintered Shard - it would start doing weird things. In the space where there is nothing around, it might start leaking as physical investiture, some gaseous nebula of raw investiture, maybe even red in coloration (wink wink). It would probably expand the Cognitive region of this part of space. Despite the fact that there is almost nothing in PR, you would step into a vast expansion of Cognitive Realm just because there is a lot of pressure from investiture of a Splintered Shard, leaking through and messing with space time of that region. It might become violent like Dor - raw power is dangerous - it might become self-aware etc. Basically everything we know about Splintered investiture of a Shard still stands in the vacuum of space, but this will certainly cause some weirdness. Brandon also said that with Ambition something similar happened to pushing investiture into CR. So maybe after Ambition fled Threnody, she was unbound from this system, Odium Splintered her and partially pushed her investiture into CR, but because it wasn't bound to any system it just spread all across interplanetary space of CR, creating the Emberdark? That's a bit of a stretch in my opinion, but who knows. Possible. He did learn and try something different. Ambition was killed after Devotion and Dominion:

More fragile or more concealed? Ruin didn't care about Mist-Snapped until Elend discovered that they are all Allomancers - only then Ruin ordered his Koloss to attack Fadrex to wipe them out. But that was just before Vin's Ascension, if that were to happen earlier, if there were Mistborn among those Mist-Snapped, all would have realized what's going on much earlier, Ruin would have kill them all much earlier as well and nobody would be able to prevent 300,000 Koloss from killing all those inexperienced Mistborn and other Allomancers. All of those electrum Misting would have been killed long before they would get a chance to ingest Atium. And once again, per WoB it takes considerably more power to snap people into Mistborn - more than what it takes to snap them into 15 types of Mistsings. It's simply too much to ask from Mists, who had to work autonomously on their own, to snap Mistborn into existence. Then there would be no 16, as now you have only 2 types of snapped - Mistborn and electrum Mistings. Remember, the knowledge of the Shard comes into a new Vessel gradually, not all at once. It takes some time for a Vessel to comprehend what's going on, even though their mind is greatly expanded. Shards aren't omniscient. Vin was Preservation's Vessel for less than a day, Kelsier for much longer. Moreover Vin had no idea there was any plan set up by Preservation at all, she didn't know she can look for something like that (and conscious searching is what makes Vessels learn things Shards know), while Kelsier knew there was some plan - Leras was constantly repeating that, he even saw glimpses of it when Leras showed him the future. Vin was far more focused on what's here and now and how to prevent imminent destruction. While she figured out Ruin was incomplete as well, she didn't know that's part of the plan, as she didn't know there was any plan. She hadn't been Preservation's Vessel for long enough to figure stuff out and comprehend the knowledge Shard possessed, or maybe even to comprehend the future sight itself. She was too fresh for it, too inexperienced and overwhelmed, while also being under constant pressure from Ruin. When Kelsier Ascended Ruin mostly ignored that, he was still focused on Vin the most so Kelsier had more freedom than Vin had as after Vin's Ascension Ruin stopped focusing on her only when he discovered where Atium is. This is evident from HoA epigraphs, where Sazed often says that he doesn't yet know something, or writes about what he believes or speculates to be the truth, not what he knows when he should have known. Plus we have WoBs that talk about it. Yes, but that was before Ruin's imprisonment, when he made all those predictions. When he gave up his mind he was unable to perceive his plan and he was just focused on keeping the status quo (the only status quo that mattered to Leras was to keep Ruin imprisoned, the rest was irrelevant) because he didn't know where it would end. He no longer knew what the plan was, he was just a shadow of his mind. And that's why every action Leras did in SH weren't done to fulfill his end plan, they were done in the blink of a moment, to serve what's here and now, not knowing how it would affect his ultimate plan. By the time of Alendi or Vin, Leras was too far gone to know what the plan was, he didn't know it, he couldn't have acted on it. While Rashek might have been part of Preservation's plan before Ruin's imprisonment, this was irrelevant when dead Leras attempted to save the situation after learning Alendi would free Ruin - at that time he didn't chose Rashek because Leras knew he had a role to play in his grant plan, he chose him because he was the closest to prevent Ruin from escaping and only that mattered to Leras at that point, nothing else. I'm not. I'm differentiating between Leras before Ruin's imprisonment, when he created his plan and acted on it, and after when his mind was gone and he was incapable of even knowing what his plan was, thus he would be unable to actually make any decision based on that plan. If Rashek were to survive and Ascend again (just as Leras hoped for) nothing would happen for another 1024 years. Rashek was also the Hero, just like Vin was. That's why I believe the plan was more general, not specific. It was meant to be set in motion once Ruin is released, no matter when. He didn't want to but he knew that's inevitable no matter what he did. Of course not everyone can do this, but everyone has the capacity to do it - that's a difference. It takes some work to understand those Shards and even Vin would be able to get that proper mindset and Ascend to Ruin, but it would take some work - just like Sazed had to work on his understanding of death. Everyone suffers in their lives, everyone loses someone important to them, grief is not something that's exclusive to Sazed. Everyone deals with it in a different way. Sazed's way of dealing with grief led him to understanding of Ruin's nature, but many could have ended up there as well. It’s hard to get to those Shardic levels, but it’s something that can still happen. I do take offense! If we start to ignore and cherry pick WoBs because they don't fit our personal beliefs, then we're stepping into shaky grounds of confirmation bias. We should be shaping our opinions based on available data, not on our wishes. I see no reason to dismiss those WoBs, Brandon planned his work far in advance, he wrote all Mistborn books at the same time, back to back, before releasing any of them, that was done specifically to pre-plan it all. Brandon has not retconed this, nor did he said something contradictory later on, those WoBs stand true.

This effect is called resonance. It's complicated, I'll talk more about it in a bit. Yup, that's just a cool thing Wax can do with conservation of momentum, not a resonance. That's true. It's worth mentioning that Wax was originally planned as a Savant, or near Savant of his powers, but Branond stepped back from this idea as there were no consequences of his Savanthood, nor was it related to the plot or his character arc. The last part of this WoB is important here - Brandon isn't pleased how Wax's resonance turned out in the book and that's probably why it's complicated. And here is the problem why it's complicated - Wax's resonance was meant to be his steel bubble. But in BoM ch 7 we saw a regular Coinshot also using a steel bubble, so that can't be it. I think it goes back to the WoB above - Brandon wasn't happy about resonances in Era 2, so he made it just a normal ability. And that means we still don't know what Wax's resonance is. Wayne is even more problematic as Brandon never said what his one is. I don't remember Dumad using a steel bubble like Wax, he had duralumin and was pushing in all directions. Do you remember where he did that? I've tried to search for it but found nothing. Wax is more subtle and skilled with his bubble, he can exclude things from it, like his and Steris' personal items, it's a bit more advanced than just "push everything away." I don't think this alone is his resonance, it's just skill with the steel bubble Wax's learned, everyone should be able to do the same, it's just the matter of perspective and intent. If Dumad really did the steel bubble, then it can't be a resonance, as those aren't transferable via spikes and they also don't develop when your powers come from Hemalurgy, but also he didn't even have the power of F-iron. There is one good news however, resonances will be explored more in Era 3, so it's a part of Cosmere that is still ahead of us. No, that's definitely not something like this. It's not really possible. If I were to guess I would say he's just better at storing/tapping health faster or something like that. Many theorize that he had increased Fortune, that's why he's so lucky and it would make sense too.

Lerasium is burnable by anyone - Eland proved it - Lerasium alloys are as well, we know this from WoBs, they make you into Mistings. But why Atium alloys aren't burnable by anyone? You have to already be a Misting of the specific alloy part to burn it, in the case of Atium-electrum alloy, you need to be able to burn electrum to burn that alloy. This is one thing that suggests to me that god metals in general aren't burnable by literally anyone in Cosmere, but only to all kinds of Allomancers. And while in many WoBs Brandon just says "Atium should be burnable by anyone, it's a god metal," in this one (which is the main reason why I think this way), he talks about how he wishes he made Atium burnable specifically by all Allomancers and that it will work like this in movies. In my opinion this just makes more sense and it's more elegant. Plus all WoBs ask what would happen if a Mistborn were to burn a different god metals and it's always about Allomancers, not a normal person - but that's also how the questions were phrased, it's not an obvious clue. I really wish Brandon would clarify who are those "anyone" that can burn god metals. It's Preservation's god metal, it's a gift that grants you strength and preserves your soul - for the same reason Endowment grants Breaths with no strings attached. It's the nature of those specific Shards. I expect Edglium to work like Lerasium as well - burnable by anyone in Cosmere. giving you a side-effect, but the main effect of those god metals is reachable only by Allomancers (from WoB: "if another Allomancer were to burn it, it would do something else"). Yes, that's just my speculation. We know too little. I just threw it out there to point out such possibility exists. And I will reference the WoB I've posted to this point - that's your body's intent in action, that's your body burning metals very slightly, rather than you. You’re burning it subconsciously only because your body has its own intent - to survive - and it will reach any available source of investiture to keep you alive. In Vin's case it was burning pewter, in Elend it reached for Lerasium, Wax reached for other metals etc. As the WoB I've posted said, your body knows what to do and it will slowly burn those metals, providing the intent, but that's not the same as your conscious intent to burn metals. All of those cases happened when they were in a dire need of this additional power. Vin was burning pewter when she was being beaten up, healing, or burning brass to avoid being beaten up, Elend burned Lerasium when he was dying, Wax burned pewter to survive Wayne's explosion, maybe iron to grab vials when falling to his death, maybe tin when he was desperately trying to look for a solution on the top of the tower etc. None of them just burned metals when walking down the street, or when nothing was happening, they all needed this power to survive, or avoid something bad happening to them - that's when their body's intent kicked in and burned metals for them. Yes, it's possible as well. Yes, that's the reason why Shardblades can't be used. They're alive. New WoB on that:

Yes, that might be it. I doubt any Shard was involved in it. Honor was raving and dying at this moment, Cultivation is a wild card, she seems to be avoiding direct interventions, hiding in the Valley, waiting for people to come to her instead. It's possible Melishi went to the Nightwatcher and met Cultivation, but on the other hand Cultivation might have seen actions of Mishram and Singers as a new growth and might not have wanted to cut it off, particularly if it could have wounded everything on Roshar - she sees the future, she should be able to see it coming, I doubt she would have wanted to contribute to that. She was unmade, but we don't know when, she might be younger than Heralds or Fused. Unmaking destroyed all memories. If she was unmade after Fused were created, she might have known Odium only in his Singer form, as that's how he always appears in their eyes. Mishram might be but Sja-Anat wanted to be free and independent, be her own god, now she's under Taravangian's boot. He knows she betrayed Odium, working against him, he has reasons to unmake her again if he wishes. But he will do everything to force her back in line and prevent her from gaining freedom, he will keep her short on her leash. That's a cool idea, sounds doable.

Suns are different for each planetary system - Kelsier saw the Scadrian sun disappearing as he walked towards Ire. That means each subastral has its own sun. SH ch 5-1: We don't really know what the sun is, it might be related to SR, or not as Shardic essence can block the sun. The SR and the Beyond are two different things, we don't know and we will never know if the Beyond is real. I have no idea how you figure that out. Is it because there is a name "basin of the veiled sun?" It's just a name, it tells us nothing about where the sun is located in CR. This name might also mean that in that region the sun is so far away that clouds obstruct its light, which would mean that the sun is in the opposite direction from Rall Elorim, or something like that.

This is weird as Brandon has previously said that there is no Unmade corresponding to Bondsmiths. I wasn't expecting heliodor to be used for Unmades because of that. I wouldn't exclude this possibility, after all Venli remarks that Nale's scar on his face looks like Singer's pattern, from Nale's memory it looks like he was an enemy to Jezrien (whatever it means) before he asked him to join Heralds, so he might be in some way related to Singers, maybe he had mixed parents, or something like that? All Heralds maybe with the exception of Ash came from Ashyn, Ash might have been born on Roshar already, Brandon isn't sure. But from all we know, Nale wasn't present when BAM was imprisoned. RoW ch 77: RoW ch 47:

I suspect that BAM imprisonment was a necessity arising not just from the fact that she started a new Desolation, but that she overextended herself by Connecting to all Singers, which strained her soul and changed her and maybe drove her to insanity so Radiants had to react to help Roshar, not by just stopping the Desolation, but by stopping her specifically. I think there are clues for that, the way Ulim talked about her in RoW to Venli, or the Stormfather to Gavilar in the KoWT Prologue - it seems not so clear as we think of it. Mishram being insane right now, not just from her imprisonment but from this overextension is highly probable in my opinion. RoW ch 73: KoWT prologue: Note that the Stormfather said that Mishram felt BEFORE she was imprisoned. I don't expect her story to be just "let's release her and everything will be as it once was." Regarding TOdium, it's possible that the fact that a human Ascended to Odium will enrage her IF Rayse was masquerading as a Singer even in front of her and she didn't know he was a human. I'm not so sure of that. I think that it's her broken Connection to Roshar, which she established to grant forms of power to all Singers, did all of this, not that she's in SR specifically. But it's possible, SR is weird and she was there while being trapped in a gemstone - somehow. It's possible, but I doubt it. But I agree, Shallan will "go" to SR, but not with her body, but with her mind. I doubt it. It doesn't fit for her to do that when Dalinar was opening a perpendicularity and Ascending in OB. There was something going on a Shardic level. I don't think she will stop hating humans after they imprisoned her for 2500 years. It might get even worse.

That was interesting, I didn't expect BAM to be imprisoned in SR. How was that even possible? Very interesting. I wonder how they will recover her, not by physically going there as from WoBs we know that's not how SR works - it's not a place (WoB1 WoB2). I thought if BAM was in the vision Dalinar had at the end of WoR - many suspect that was a Dawnshard, based on how similarly it felt to Rysn becoming the Dawnshard, but could it be BAM, and those feelings and light was just the consequences of her essence and investiture bleeding through SR into Dalinar? I did expect that not many Honrospren would join Radiants, but not that few. However I think Notum will organize the Honorspren navy to recover Shadesmar from Odium's control, the hint of this was quite clear in my opinion. And lastly we have confirmation that Shallan draws upon Fortune when drawing, which wasn't surprising, we knew from WoBs that Shallan fiddles with Connections and SR, but what was interesting is that Kalak for some reason seemed to be not surprised by that, even expecting that. Weird. Does he know about something we/she doesn't know (Chana)? Love to see Maya speak so much, she's really getting better

RoW spoilers:

Yes, I agree, Nahel Bond might help them, but it won't cure them. I did say it might brace their souls. But as you said, bonding a spren will deal only with a part of the problem - their trauma, manifestation of their broken soul, which is their madness, but won't fix their soul. For Ash Dustbringers are an excellent choice as they are all about self-control over their destructive potential and Ash right now struggles to stop herself from even thinking about destroying her religious images. Nale lacks emotions and compassion, Edgedancers might be great in helping him see his flaws - Lift proved this already. I have no idea about Ishar - maybe Lightweavers? He lies to himself about being Almighty, Adonalsium and all this stuff, a healthy dose of truth and self-reflection might be helpful. Taln is beyond the help of Radiant Ideals, he's broken the most. He suffered thrice as much as the remaining nine. He’s now in vegetative state, unable to respond, communicate, or even think. This won’t help him at all, when he can't even say the Words. But all of this, while helpful, is treating the symptoms not the disease itself. Their soul is still overburdened by their age, their trauma, layers of PTSD and memories of endless torture on Braize. All of this is beyond what a human soul was made for. A direct Shardic intervention might fix them, a Shard might be able to reinvest them, create another fresh copy of their soul with no cracks, no memories of past torture - basically create a Cognitive Shadow of a Cognitive Shadow. But that would kill them anyway, this time we do like Vasher said, we create a copy of a soul while the real one is fading into the Beyond. This time we all know they are not those people anymore, they are just copies. I don't want to suggest this is the only way of healing Heralds, certainly it can't be, but this is the "easiest" way of doing so - from the perspective of those who aren't Heralds of course as for them there would be no difference in curing the real Heralds, or making a copy of them.

No, because that doesn't affect how their soul ages.

There is always another WoB

The problem with Heralds lies in their soul, which is broken beyond what's humanly possible. They've lived for thousands of years and a human soul isn't made to exist that long, on top of that most of their existence was on Braize, being tortured again and again and again. Something like this is impossible for a human soul to withstand, even a heavily invested one. A spren bond might help brace the soul and mitigate some of those effects of madness, but as seen from Nale that's not really making any difference. A Nahel Bond can also have the opposite effect, it can widen the cracks of their soul, breaking it even more. To help Heralds you would probably have to deal with their trauma first, but that alone isn't enough. You would need to somehow fix their soul and make it functionally immortal and that's the biggest challenge as a human soul simply isn't made for that. WoR Synopsis:

Just to point out, we don't call Stormlight as Honorlight, Voidlight is not Odiumlight, so why would Warlight be of War Shard when all other light names don't include the names of Shards they represent? I don't think the combination of Honor and Odium will be War. Science is more likely as the light's name is Towerlight and it does represent science as Navani said.

Firstly, I'm gonna start by saying that when Brandon says "anyone can burn god metals" he means any Allomancer, not every person in Cosmere. Only Lerasium is different, as Lerasium granting Allomancy is just a side effect and an Allomancer burning it would do something else. This is my opinion, I think some WoB points towards that conclusion, but that's debatable. As it was said by others before me, the knowledge about god metals on Scadrial is very basic, they don't even know that Era 1 Atium was just an alloy and not a pure god metal as they think it was. And what do they know about this supposedly pure god metal - it can be burned only by either a full Mistborn, or a specific kind of a Misting created by Preservation to specifically burn this god metal (they didn't know they were just electrum Mistings). So Scadrians know that it takes a special person to burn god metals, but those are absent from their society for at least 200 years now, as Spook was the last full Mistborn alive. Why even try this when you know you have no hopes of succeeding? Another factor is the intent. It's not as easy as swallowing a metal and burning it (while it mostly seems like that's it from Vin's experiences in Era 1), it's a bit more complicated than that - that complexity prevented Inquisitors from gaining the ability of compounding, despite the fact that they'd started to mix Feruchemy and Allomancy after Rashek's death. Compounding is just Allomancy with a new type of metal, but to actually burn those metals you need to have an understanding of what's happening and what it might do to you. A kind of understanding that would take some time to develop when trying to burn a new type of a god metal. Set might have concluded that Trellium does nothing (or that it can't be burnt) because they've failed to develop this proper intent - if they even tried burning it at all, which I think is doubtful. In terms of using Trellium as a metalmind, we're going back to my first point - they really had no idea that god metals can be used Feruchemically by "anyone," truthfully we don't know that either. There was never any example of someone who was not a Feruchemist that was using a god metals, we only know that Atium-electrum alloy can be used (they believe it's pure Atium) but for that they need to be a full Feruchemist - those are gone now. There is no point in trying when they know they will fail. Moreover I believe that it's not as simple as touching a god metal and storing something - again, you need to know what it does, you need to know what attribute to store, you need to have this proper, very specific intent. You can't just randomly store something without knowing what it is. Set had no chance of actually succeeding by their understanding so why waste precious resources in vain when they can use Hemalurgy, an art that literally anybody can use and they know that. And with that I think it's pretty reasonable why nobody ever tried to use Trellium Allomantically and Feruchemically. Scadrians believe that you need to be either a full Mistborn or a Feruchemist to make use of god metals and those are gone in Era 2. Additionally you have to have a proper intent, which encompasses understanding, which is hard enough to develop that even Inquisitors who knew of compounding, never succeeded in doing that after Rashek's death (Marsh for example). Then there is one question left to answer - why we've never heard about any Set attempts to burn Trellium. The answer is comically simple - we had no PoV of theirs, the story was focused on Wax, Wayne and Marasi, not Set members. Our protagonists weren't members of Set to actually know about their experiments with Trellium - we've only seen their successful effects. Autonomy's god metal was always a mystery for W&W and therefore for us. But I do agree with you that this issue should be mentioned in the series somewhere. I wish Brandon addressed Atium retcon in Era 2 and what it means "anyone can burn god metals" and using Trellium to explain this would be great, even if nothing were to happen. But for me it’s more like a missed opportunity rather than a plot hole. Actually Set gained their knowledge about Hemalurgy from interrogating someone who knew a lot about it, but didn't want to cooperate (that excludes Paalm). We don't really know who that was, in my opinion there are only three people that fit this - Kelsier, Marsh and Spook if he's still alive (which is likely, he has cadmium). I doubt Kelsier, the Ghostbloods' leader would allow himself to be caught by Set, I doubt Marsh the Death with all his powers would also be caught by Set, so that really leaves Spook, or some unknown person/Kandra as the only option. Either way, they still had to spend years to get where we saw them in Era 2. It took them at most 6 years to jump from 3 spikes to 4 and to make a better Chimera with 2 spikes - and that was when they were already advanced in their knowledge of Hemalurgy. And because it took them years to succeed in using Trellium Hemalurgically, I highly doubt that they would waste time and Trellium to figure out how to use it with Allomancy or Feruchemy, especially when they believed that only a full Mistborn/Feruchemist can utilize them in those arts.

RoW ch 114: In my opinion this suggests that once you swear the 4th Ideal, you've got the same group of Lesser Spren hanging around you, ready to become your Shardplate at your command. But that's only after you swear the 4th Ideal, before you just attract any Windspren close to you, and that is what Kaladin was doing before RoW in my opinion. It even makes a little sense. Kaladin and Syl need to be close together, otherwise Syl will start losing herself and they will lose awareness of each other, as seen in RoW. What if Kaladin was in a place with no wind and no Windspren? He would be unable to summon his Shardplate, if he just summons random spren that are close by, as they should also work by proximity like Syl does. It makes more sense that once you obtain a Shardplate, those spren are staying close to you, so no matter the location you're in, you can summon them.

HoA: Her mind and attention was focused on the fight. Just being on Roshar isn't enough, they need to look at it and Shards can't infinitely divide their attention, their minds aren't infinite. I think that too about the Stormfather, but he's also Honor's Cognitive Shadow, he should have Connections to all pieces of Honor, even if they aren't attached to him. It might be problematic to reach them for someone like Dalinar, but that should be possible in my opinion. Spren existed before Honor's death, they weren't created during the Splintering of Honor, they should not matter in recreation of Honor. I don't count them as pieces needed for that. I do think there are larger Splinters of Honor in SR, not aware, just raw power staying in SR, but because of Stormlight, Spren and all this cycle of investiture on Roshar, which circulate massive amount of investiture compared to other places, this raw power stays dormant, it doesn't go nuts like Dor for example, as all this cycling provides a relief. I don't count Splinters/Spren as necessary elements for Honor's recombination. They are sentient, they've existed long before Honor's death, they were made by Honor in the first place and they are fully autonomous. Spren are just a drop of water in the ocean of power that a Shard holds. I do agree that there is something else, but I think it's just a raw power left Splintered in the SR, as there is no evidence for any Splintered raw power of Honor existing in CR or PR.

To Soulcast. To give them Stormlight, transport your image of change into them and to change their soul. It's not just talking, it's commanding and pushing through the resistance of their soul to make drastic changes in it - something that requires certain abilities. The change itself is the Surge of Transformation. You are changing something important in their soul and they can't just do it, that has to be done via some ability, the Surge of Transformation. It's possible. You need to be at least invested to sense what impression the bead is carrying, it's possible you need to have specific abilities to connect between CR and PR - Shallan is able to move into CR due to the Surge of Transformation. Stormlight has to come through you. That's why Soulcasters are turning into essences they use. it's you who makes a transformation, not the object. The object nearly accepts it, but this acceptance isn't required, as Jasnah proved when she Soulcasted people. Yes and no. The Surge of Transportation represents one of the fundamental forces of Cosmere, the power of Creation itself, just like Allomancy does. The specific Surge used by Knights Radiants is manifestation of this Surge filtered through Honor and Cultivation. On Ashyn that was because of a Dawnshard. Ability to access that force of creation. That's the piece of the puzzle you're missing. You can't use it if you can't access it. You need to bond spren or be an Elantrian to do that. However I will give you that - Dawnsingers were able to do that. They could shape and change things with their songs, so this might be possible for some with special abilities. But now it's forgotten and Hoid is not a Dawnsinger. RoW ch 67:

Sorry, I had no idea what the Alleyverse is. In that case it sounds like you can use that investiture from the Alleystorm to fuel your Feruchemy, as long as it's unkeyed.
