  1. Would it be possible to create a Fabrial, one that mimicked Invested powers, if you used a Hemalurgic spike in place of a Gemstone with a captured Spren?
  2. I'm sure someone else has already asked this... But could you hypothetically create Atium on Roshar? I have no Idea how you would... but if you did, what kind of fabrial could you make with it? I have to bring up another question.. If Atium was created by turning the body of Ruin into metal, could other -different- god metals be created by using the bodies of the other shards?
  3. Ok, so I'm trying to wrap my head around how fabrials, spesifically conjoiners work. To look at spanreeds, I understand that each twist or notch ,probably puts it in contact with a different metal, makes sense, but I'm not sure what metals those would be. Now at first I figured it was Peter with a gravitation spren, but since most conjoiners are Ruby's with flame spren I assume this is not the case, so what metals cuase a conjoiner to flash, move and recive? My second question is how kaladin "glove that flies" , I get that aluminum,can prevent a plane or vector from being transmitted, but I'm not sure how that allows for translating one force vector into another, specifically "down" into wherever kaladin points" Thirdly painrials what are they, I thought it was a tazer, but apparently it supresses pain and can have it polarity changed by steel and iron rather than zinc or brass, so can someone explain that? Also I'm a second year physics student so dont hold back if the answer needs to get technical
  4. The coppermind article lists three categories of fabrial (as in-world artifabrians see it): altering, pairing and warning; which doesn't account for ancient fabrials or even most of the modern ones. This seems erroneous to me. I see these instead as sub-categories which fit into two different categories of fabrial, with surge fabrials being the third kind. I'll explain; and please, let me know what you think. First there are the ancient/Surge fabrials, which are manifested sapient spren (as far as I understand) and replicate the Knight Radiant powers. I see them as pseudo-fabrials because although they look like a technological device, I think they are just an expression of magic (possibly Willshapers and/or Bondsmiths but that's another theory). Second there are the common/modern fabrials, which use metals to induce a spren captured in a gem to interact with its concept (flame, pain, etc.). What they affect is determined by the type of spren, possibly modified by the type of gem, and the effect is determined by the metal. The known types so far are altering, warning and attractor fabrials. I think of them as 'true' fabrials since they require an artificial mechanism beyond the spren-in-a-gem to function. Third is the new category of fabrial I am proposing (not sure what to call them, spren fabrial maybe?) which for now only includes pairing fabrials and fabrial clocks. They are halfway between the other two categories, relying on a lesser spren trapped in a gem but producing an effect related to Surges the spren is linked to without needing metals. The pairing and clock fabrials both use a platespren (flamespren haven't been confirmed but almost certainly are) so they have an inherent relationship with two Surges through the corresponding Order. The Surges in these fabrials are more conceptual/Cognitive expressions, and there seems to be an activating one and an effect one: flamespren in conjoiners will move sympathetically (Abrasion) when they are split in half (Division), logicspren in clocks will change their brightness (Transformation) regularly when there is a constant change in the available Stormlight (changing context, Transportation). The type of gemstone used also seems to relate to the Surgebinding table, with ruby having a standard effect for flamespren (both associated with Dustbringers) but an amethyst inverting the effect (being linked with Willshapers, opposite ruby); clocks use smokestone (opposite Elsecallers) and presumably zircon is best for capturing logicspren but the inverted version of a clock is too obscure to have been discovered yet, perhaps it works as a logic gate of some kind. I'm very curious what other platespren would do in these fabrials.
  5. I'm putting this under Cosmere discussion, even though it only really pertains to stuff in the Stormlight Archive. First of all, thanks to @Ranryu for reminding me about the weird things spren do, which led to this theory. Brandon has said that all the planets in the Cosmere could one day develop faster than light (FTL) travel, though Scadrial is expected to achieve it first of all. This is really interesting to me. We can see how Scadrial, most likely with some applications of speed bubbles, access to the spiritual realm, and the handy technology of Ettmetal, could achieve this pretty soon. But what always interested me was the other planets. How could worlds like Roshar or Nalthis achieve FTL? Their magic systems don't really have anything that could be used in that way, and it seems incredibly far off. (Sel technically already has it (Aon Tia), they just need to work out some kinks and figure out how to use it offworld. Can't be widely applied at this point.) Now focusing on Roshar. I think, with many of the technological developments that are coming around as we read, it's safe to assume that Rosharan FTL will be fabrial based. And what do you need to power fabrials? Spren. In an interlude in Words of Radiance (I think it's WoR, anyway) we see a pair of ardents conduct some experiments on some flamespren. They find that once you define a specific value for a measurement of the spren, the spren has to stay that value in that specific measurement. This coincides exactly with our current understanding of quantum mechanics: particles exist in a fluid state, in multiple locations or states of being at once, until they're observed. After observation, they're stuck in the position or state they were observed in. I think it's safe to assume that other spren share this attribute, but right now, only flamespren are confirmed to have these strange quantum properties. And, unless I'm remembering wrong, flamespren are the most commonly used spren when creating conjoining fabrials. Conjoined fabrials are very handy, as we see with the Fourth Bridge in Rhythm of War. Using some clever tricks involving Aluminum, a latticework of conjoined fabrials are effectively able to create an airship. This kind of fabrial is probably the future of Rosharan transportation. Now here comes the long shot. My theory is that if a fabrial were to be created that somehow exploited the quantum properties of spren, they would be able to use that "multiple locations at once" function to effectively transport a vehicle using the fabrial to another location faster than the speed of light. I have no idea how you'd do that. You'd probably have to use some kind of trick to amplify very small scale effects to an incredibly large scale, and Aluminum to isolate variables and make sure your spaceship actually appears where you want it to be. It's a long way off, if it's even possible. But Brandon is hinting at something with those flamespren, and it seems likely that it's something along these lines. What do you think? Am I grasping at straws, or am I onto something? Tell me below!
  6. So I was thinking about the application of fabrials in the future of the cosmere (like around mistborn era 4) and was wondering how these could be used in some interesting SF ways. One of my first thoughts was mechas. I wondered if it would be theoretically possible to build a mecha using conjoined fabrials. Say you built a suit for the 'pilot' with rubies at key joints e.g elbows and then had the matching set attached to the mecha would you theoretically be able to use it?
  7. I didn't find anything else about this on here, so I'm proposing this idea. I can see painrials being used as taser-like weapons for law-enforcement officers and maybe even self-defense tools for regular people in the future. What do you think?
  8. Using a future version of Navani's flying barge, could it be posible to fly over the highstorms and sail all the way to their origin? Could a skybreaker/windrunner and bondsmith pair fly there? bondsmith as the power source for the other radiant XD If posible, any idea what could be there? just open seas? Stormsfather's kame hause? Another weird lost Island littered with gemhearts?
  9. This isn't a theory discussion thing, because I don't really think my theory is right. I want to hear other solutions too Ok, the one thing that I completely didn't expect from ROW is the siblings distaste towards fabrials and just how much time was devoted to it. This is a situation that when I was reading the book, I had absolutely no idea how to resolve it, and I still don't. Fabrials are getting more and more important to overall story of SA and the cosmere. The desolation is causing pressure on Roshar on developing technologically. This will be helpful for the later space age cosmere in the future. When I saw the epigraphs of ROW, I was sure that I knew where this was going, that this is the seeds from which they will have fabrial computers and stuff in the future. And then the book slaps the reader in the face with a core problem with making fabrials in the first place. The spren get trapped and the sibling does not like it. So what's Navani's solution? How can she keep having fabrials without trapping spren?I can think of three things 1) That spren will be asked to manifest into the physical realm and make new fabrials. This is how the sibling does it. Also this is how soulcasters are supposed to work, navani sees some spren sleeping in the CR side of a soulcaster. This is how the ancient fabrials seemed to work( during knights radiant days). But how does this work tho? Which spren will be asked? What about all the other spren that you need to use for specific effects(like flamespren, painspren), where do they come in? So many questions 2) Fabrials were based on the gemhearts of the singers and the greatshells and others. Are the spren they use trapped inside the living beings? Do luckspren live inside a chasmfiend? If so , I really have no idea why the sibling takes so much offense to their imprisonment, since that clearly already happens in the normal, natural cycle in this planet. If they are not trapped in gemhearts then, what does that bond actually look like? Are gemhearts only for storing stormlight all this time? 3)My theory: The process will be like awakening. They will take a core physical seed, ( like an empty gemstone wrapped in a metal cage), then pump this object with stormlight, talk with the cognitive aspect of the object, then command it to manifest in the investiture it has into specific fabrials. I like this also because you are creating specific spren for your specific needs and then commanding it to perform a certain function. Rather than having potentially sentient computers, which I think is silly. What do u guys think navani's solution will be?
  10. I saw this WoB about a spear being thrown through a speed bubble, and Brandon said the spear would be either in or out of the speed bubble, based on how it views itself. How do conjoined fabrials view themselves and does that affect their interactions with speed bubbles? For example, if you have a spanreed inside a speed bubble, and its paired spanreed outside, do they view themselves as one thing, and if so will they both be counted as inside or outside?
  11. Just noticed, in Oathbringer, the Reachers appeared to be using veins of copper (or bronze) running across the ship to communicate with each other without speaking.
  12. Just wanted to point out that Allomantic Steel and Iron function similarly to Conjoiners and Reversers. Allomancer burns the metal -> Blue lines (Connections) appear -> Allomancer pushes or pulls on a line -> Force (generated by Preservations power) is transferred through the line, making the object move. A Conjoiner (a reverser) is created -> A Connection between the two halves exists but is not visible by the naked eye -> The halves are conjoined, the Connection snaps in place -> Conjoined halves behave as a single object, effectively allowing to transfer force. There is no real point to this, except that using Connection manipulation, a trapped spren, and some Stormlight Bondsmiths can practically do telekinesis.
  13. Ok, so I just read Dawnshard (because I didn't realize it existed until last week) and my engineer brain has been percolating ideas for how to improve Rysn's mobility, and make her more self-sufficient. Here's an idea I've come up with. Take her chair, and affix a freely rotating crank approximately 7 inches in radius to the side of it at a height which makes reaching both the top and bottom edge of it comfortable for her. The handle of the crank will be about 6 inches out from the center, and will be -- for lack of a better term yet -- a spanreed. (We'll probably want to make this spanreed more like a belaying pin in size and shape, in reality.) Put another of these spanreed-belaying pins on a similar crank in Rysn's cabin. This crank is on an axle, but is rigidly affixed to a small diameter gear. The small diameter gear is meshed with a larger diameter gear (ratio TBD for Rysn's convenience) which is, in turn, rigidly affixed to a capstan. The capstan has a line which runs vertically, with a very small weight on the end (for stability) and a number of conjoined gemstones that match the ones in her chair. The weight and gemstone plumbob should be constrained in a tube. Yes, the selective dissociation of forces means she won't move side to side if the bob swings around, but she would bob up and down as the cosine of the arc it describes. Give the crank on Rysn's chair a setting brake so she doesn't have to worry about inadvertent vertical motion, and using the power of gear ratios and conjoined gemstones, she can crank herself both up and down. If the tube is the same height as the ship, she could go all the way from the hold to the top deck under her own power. It might even make sense to run this device from the top of the Eelsnest. It should be noted that we're not using the "opposed motion" principles of Navani's archery platform. The gemstones in Rysn's chair and on the capstan line move in the same direction, not opposite. So she's not using a counterweight to lift her, she's doing it herself with her own muscle power. -Hephaestus
  14. One of the things that has perplexed many of us for some time is the so-called "missing Shardblades:" the absence of the many Shardblades we see in Dalinar's flashbacks of the Recreance. In Rhythm of War, we learn that the "ancient fabrials" such as Soulcasters are actually the physical representation of spren- specifically Radiant spren. Kind of like Shardblades. I think it's possible that after seeing the destruction wrought by their weapons at Feverstone Keep, many of the other Radiants decided not to drop their spren as Blades, but as something else- this could explain both the lack of Shardblades and the strange observation Navani makes that the Soulcaster spren appear like a Radiant spren. The physical appearance and function of these devices would vary, but we do know that some Soulcasters only deal with certain materials- and we don't know what other devices could have been ignored in the post-Recreance destruction. This is a very hot take that I got while listening to the newest Shardcast episode. Let me know your thoughts!
  15. Last time, we talked about the Rhythm of War Part One epigraphs and the fabrials details there (which you can check out here: ). This time we are going deep into the new things we've learned in Dawnshard and Rhythm of War, and boy. There is a lot. We get solidly into the weeds here on mechanics, aluminum, and the ancient fabrials. We have Eric (Chaos), Ian (Weiry), Evgeni (Argent), Joshua (jofwu), Marvin (Paleo), and Rosemary (Kaymyth). 00:00 Introduction 3:57 Fabrials 6:10 Aluminum, Frame of Reference, and Spanreeds 27:39 More Aluminum: Tomor's Glove and Fourth Bridge 41:06 Force Multiplication 48:47 Ancient Fabrials 1:29:49 Suppression Fabrial 1:54:25 Who's That Cosmere Character If you like our content, support us on Patreon: For discussion, theories, games, and news, come to Come talk with us and the community on the 17th Shard Discord: Want to learn more about the cosmere and more?

  16. So, during the first few chapters of Rhythm of War, we read Navani's lecture before the beginning of each chapter, and my mom who just started reading noticed something. Each of the metals pointed out in the lecture are all Allomantic and the effects it's stated to have on spren almost exactly match up. For example: Zinc (aka Rioting) - Causes spren to more strongly manifest in gemstones Brass (aka Soothing) - Causes spren to weaken and withdraw in gemstones Bronze (aka Seeking) - Creates warning Fabrials that can detect objects or entities nearby Pewter (aka Thugs) - Causes a spren's attributes to "express its attribute in force" She also noticed that in Chapter 8, whatever Renarin did to Moash strongly resembled the Eleventh Metal, although I am less sure of the connection between that event and Allomancy. Has anyone else noticed this?
  17. I was doing some digging around on the Coppermind and I had an idea. We know already that metals used to make fabrials often have similar effects as the same metal's use in Allomancy. For example, iron in a fabrial housing makes an attractor, while steel makes a repellent. We see the Fused making use of a fabrial that blocks Radiant powers, and Urithiru has defenses that block Fused powers. What if these fabrials are using chromium housings? Chromium is used in Allomancy to wipe out someone else's metal reserves, but there's also this little tidbit: These effects can be seen: All this being said, I can't actually remember if the metal in the fabrial used by the Fused was identified or not. So I might be entirely wrong. Not sure if I need to spoiler tag things, but I did just in case...
  18. So, the Ch. 15 Epigraph mentions logicspren and one their purposes in advanced fabrials. During the discord discussion, it was brought up that Aon Ene, which means logic and debate, is used as a linking Aon to join lists together and to determine their timings. We know of only one other linking Aon, Ehe, fire, and it is used to start other Aon Chains. It was theorized that flamespren could be used in fabrials to the same effect. This is kind of hinted at with what Rushu gets distracted reading, the interestinmg interactins of Logicspren and Flamespren. So, yay! for that theory. Now questioning time, what other spren/Aons can be used for similar purposes? I would guess the Aon Soi, meaning "order" for the creation of lists and chains, and possibly Orderspren or Neatspren for the fabrial purposes. Aon Soo means "mathematics" so possibly some combination of effects? What d'y'all think?
  19. In which way do you think ferruchemy and hemalurgy will affect fabrials? Imagine the possibilities, like maybe projection to a feruchemist stored memory or something crazy like that
  20. I. The Death Rattle The Coppermind has the following explanation for this Death Rattle: "This rattle apparently refers to the sixteen Shards of Adonalsium, three of which (Honor, Cultivation, and Odium) are invested in Roshar." But that is obviously wrong, Odium has not invested in Roshar, he refuses to invest anywhere because that would prevent him from pursuing and killing other shards. At present he is confined to Braize because of his pact with Honor. A much better explanation of the Death Rattle is that initially Honor, Cultivation and a third shard were the ones who had invested in Roshar. II. A New Shard Which shard could that be? A WoB from 2017: Since the entire Rosharan system was created by Adonalsium, Ingenuity would be a good fit, it would be naturally interested in an ingenious creation of Adonalsium. III. Fabrials The magic associated with Ingenuity would be fabrials. Moreover the current fabrials are imitations of Ingenuity's true fabrials which won't require enslaving spren. Ingenuity's magic is the creation of preprogrammed machines that run on investiture without the someone actively channelling the investiture. Basically Ingenuity allows for Automated Magic Machines also knowns as "AMM Machines" :)) IV. The Sibling The godspren of ingenuity is the Sibling (similar to Honor and Stormfather or Cultivation and Nightwatcher). The Knights Radiant have investiture from all three shards, Honor, Cultivation and Ingenuity. In particular if we set aside Bondsmiths the remaining nine orders are divided into three groups of three each dominated by one of the shards. In particular Willshapers and Dustbringers have more Ingenuity than Honor or Cultivation (and there is of course the idea that shardplates are themselves a type of fabrial). V. Leaving Roshar When Odium killed Honor, Ingenuity (a) was scared; (b) felt responsible; (c) was responsible; or (d) a combination of all three. So Ingenuity left Roshar which resulted in the Sibling slumbering (or maybe he deliberately turned it off). VI. Predictions RoW focuses on Willshapers (an order close to Ingenuity) and Navani is trying to awaken the Sibling while advancing fabrial sciences. I think this book will have a lot of information about Ingenuity here are some other predictions: Navani will awaken and bond with the Sibling making her the second Bondsmith. Remember the way to access a shard's invested art is related to their intent (for example you have to "ruin" something for hemalurgy). So you have to do something ingenious to get to ingenuity's magic and Navani with her ship is all set for that. Mirroring Frost's reply to Hoid in WoR we will either see a letter from Hoid to Ingenuity or Ingenuity's reply to Hoid (there are two ways to mirror). The Dawnshards will be related to Ingeniuty. VII. Odds and Ends I picked Willshapers and Dustbringers as close to Ingenuity because both orders are closely associated with engineering, logistics, building and infrastructure. I found it interesting that both the lightspren and the ashspren have the most negative view of the humans. This might be related to Ingenuity's role in Honor's fight with Odium. And here is my grouping of the Knights Radiant orders: Honor: Skybreakers, Windrunners, Elsecallers. Cultivation: Truthwatchers, Edgedancers, Lightweavers. Ingenuity: Willshapers, Dustbringers, Stonwards.
  21. Chapter 14 Voice Why would you need a logicspren to power a fabrial that already uses a different spren, stormlight, and metals to produce an effect?
  22. Im wondering if anyone knows if Brandon calls out specific gem cut styles when describing gems for Sphere and fabrials. It seems likely specific cuts are better then others rather than it being an arbitrary detail. Coppermind only says that cut gems hold more stormlight somehow. Hopefully this question doesn't Rafo'd or something.
  23. Yes, technically there are already two other threads about this. I still started this one, since it's a little different topic: instead of speaking mainly about fabrials, here I wish to discuss the connection between every application of any metal in the four magic systems: allomancy, feruchemy, hemalurgy and fabrials. I might've lost myself in the middle of that sentence, I hope you understood me. anyway, what we've seen so far: Iron - A: pulls on metals. Fe: stores weight. H: steals strength. Fa: changes polarity (whatever that means)/attracts attribute. Steel - A: pushes on metals. Fe: stores physical speed. H: steals physical allomantic powers. Fa: same as Iron. Tin - A: enhances senses. Fe: stores senses. H: steals senses. Fa: diminishes attribute. Pewter - A: enhances strength and balance. Fe: storing physical strength. H: steals physical feruchemical powers. Fa: expresses attribute. Zinc - A: riots emotions. Fe: stores mental speed. H: steals emotional fortitude. Fa: manifests the spren more strongly. Brass - A: soothes emotions. Fe: stores warmth. H: steals cognitive feruchemy. Fa: makes the spren withdraw. Copper - A: hides allomantic pulses. Fe: stores memory. H: steals mental fortitude, memory, and intelligence. Fa: unknown. Bronze - A: allows to hear allomantic pulses. Fe: stores wakefulness. H: steals mental allomancy. Fa: warns of things getting close. Aluminum - A: wipes internal allomantic reserves. Fe: stores Identity. H: removes all powers. Fa: cuts connection, no other known function. Duralumin - A: quickly burns any burning metals in powerful burst. Fe: stores connection. H: steals connection and identity. Fa: unknown. Chromium - A: wipes out target's allomantic reserves. Fe: stores furtune. H: might steal destiny? Fa: unknown. Nicrosil - A: enhances allomantic burn of target. Fe: stores investiture. H: steals investiture. Fa: unknown. Gold - A: shows past self (or alternative present self). Fe: stores health. H: steals hybrid feruchemy. Fa: unknown, probably known in-world. Electrum - A: shows possible future of the burner. Fe: stores determination. H: steals enhancement allomancy. Fa: unknown. Cadmium - A: slows down time. Fe: stores breath. H: steals temporal allomancy. Fa: unknown. Bendalloy - A: speeds up time. Fe: stores energy. H: steals spiritual feruchemy. Fa: unknown. Now, there are patterns inside each magic system, if you look for it, though so far only allomancy and hemalurgy have sensible division for each metal. For now, it might be better to stick to discussing only the lower metals - the first eight, since we understand those the most, and know mostly all of their applications in the magic systems (lets use the acronym MS for that) in discussion. Tin is irregular because it's the only one that does exactly the same in the first three MSs. I can't actually see any thorough connection between one metal's applications in all the MSs, and it's a little late at night in my country, and since I'm also lazy I'll leave you to think over it.
  24. Theory on the Sibling: The Sibling was the “Godspren” who managed Urithiru, and was capable of a Nahel Bond to a Bondsmith. I believe that the Sibling is inside the gemstone column in the Urithiru gemstone archive. Allow me to explain why. So, we know that a very powerful spren can be captured in a sizable perfect gemstone. Such a gemstone could potentially be used to create a Fabrial. Both Shallan and Renarin have claimed that Urithiru is not a collection of Fabrials; rather, it is a single Fabrial. This brings us to the gemstone column in Urithiru. None of the gemstones on the column look like they would be able to hold a spren as powerful as the Sibling. However, all we see is the outside of the column. On the inside, I believe there is a massive gemstone, possibly an emerald or ruby, that contains the Sibling. The gemstones on the outside of the column are likely tied together with metals to the interior main gemstone where the Sibling resides. These exterior gems hold spren are probably used by the Sibling to regulate the tower’s functions somehow. Whomever the Sibling is bonded to can request the Sibling to do something, such as increase crop production. The Sibling then activates the specific set of Fabrials in the column that controls such a function. There may be a failsafe if the Bondsmith bonded with the Sibling dies, although the Sibling could probably run the tower on its own. In addition, Renarin claims that the column is a Fabrial that is used to “be a city.” This adds to the possibility that the Sibling is inside the column, as many of the speakers in the gemstone recordings associate the Sibling with the tower itself. One of the principles of Fabrial technology we have learned from the epigraphs is that a spren cannot inhabit a gemstone with Stormlight infusing it. It stands to reason that the reverse is true; Stormlight cannot infuse a gemstone with a spren inside of it. Dalinar cannot infuse the column is because the Sibling is inside, as well as the other spren inside the gemstones making up the column. Syl mentions that Urithiru once glowed with a strange kind of light in her interlude. This could be the kind of gaseous Investiture associated with Cultivation (growthlight?), or it could be spren inside Fabrials, which sometimes glow with abnormal colors according to Navani’s prologue. Navani mentioned in Oathbringer that Urithiru has a “heart of emerald (pulp) and ruby(fire), with veins of garnet (blood).” When the Sibling is awake, perhaps these veins glow with Stormlight, Cultivationlight/Growthlight, or another color altogether. Another possibility is that, instead of the Sibling being inside a perfect gemstone, the Sibling was wounded somehow. To repair it, the splinters of its power were gathered and placed inside smaller gemstones and weave together with a lattice of metal. So then, what happened? Before the Recreance, the Sibling withdrew. Many of the tower’s functions stopped working, prompting the abandonment of Urithiru. What I believe happened was that, a bit of time before the Recreance, the Bondsmith bonded to the Sibling broke his/her Oaths. The Sibling was too powerful to be turned into a deadeye, but was sent into a coma-like state. This “slumber” is why the tower stopped working, and hasn’t for the last 2,000 years. This aligns with what the Stormfather said when Dalinar asked about the Sibling: “you have hurt them enough!” You (a Bondsmith) have hurt (broken Oaths) them (the Sibling). None of the Gemstone recordings mention a Bondsmith breaking their Oaths, as it would be a huge blow to morale. Where are we now? It has been 2,000 years since the Sibling began it’s slumber. Awakening the Sibling will be a difficult task, requiring more than just zinc wires. I believe that it will require a person with a personality similar to what kind of people Bonded with the Sibling in the first place. Such a Bond will be necessary for the Rosharans to survive the True Desolation. What does everyone think of my theory?
  25. So I’m doing a reread of Oathbringer and at the beginning of Shallan's chapter The Girl Who Looked Up she is thinking about the tower. She says something about the tower being a skeleton and the strata being veins. Here's the paragraph: That got me thinking about how Urithiru might have been like a fabrial and all that. From there I started comparing it to a body. If the gemstone tower is the heart, then what if the strata is actually gemstones that are like veins. They carry Stormlight. That would provide illumination and spread Stormlight throughout the tower. I don’t know if this would actually be possible, but it got me really excited when I thought about it. I just found some more evidence. At one point Shallan mentions that the strata has an emerald cast. “An alien color for stone.” I doubt the strata would have been heavily researched. It is often described of having a red cast, which could be ruby.
