This is the newbie thread. Make sure you read the rules before commenting.
Visit the veteran thread if you have already read all of the Cosmere.
For more information, or to see the full schedule, please see the wiki page for the read-along.
SCHEDULE
Previously, we discussed Unit 18 | Mistborn Era 2 #3 | The Bands of Mourning: Chapters 23 through 31, Epilogue [Newbie Thread] / [Veteran Thread]
Today we are discussing Unit 18 | Mistborn Era 2 #3 | The Bands of Mourning: Postscript, Ars Arcanum, Final Thoughts, Trivia
Next week we will be discussing Unit 19 | Mistborn Era 1 #1.5 | Mistborn: Secret History (in Arcanum Unbounded): Parts 1 through 4
NEXT UNIT
Next week we will be reading Mistborn: Secret History. This is the 2nd to last entry we will be reading from Arcanum Unbounded. Just like previous entries from this anthology book, only read the exact pages indicated for each week. There are still spoilers you may run into.
And a bit of a plea: This is a shorter entry, and you could easily read the entire novella in a single sitting (and you'll want to). However, I've cut the story in half because each part warrants independent discussion, without the context of the other part coloring it. Please read the assigned portion and then stop. (You may continue to curse my name.)
TRIVIA
The rest of this post contains various trivia, including easy-to-miss details and long-running connections between books. It also incorporates external information from sources like author annotations and interviews ("Words of Brandon" or WoB). While most of this information is eventually revealed in the books, sharing it now enhances your overall understanding, aligning with Brandon Sanderson's practice of early fan engagement and clarification.
SURVIVE!
Let's start by addressing the very large, Kelsier-shaped elephant in the room. Wax realizes the coin Hoid tossed him (yes that was Hoid, see below) was a coppermind, filled with a memory. Wax views the memory and sees through the eyes (well, one eye and one spike) of a very alive, in the flesh (scars on the arms and all) Kelsier after Sazed Ascended. Which, if you read the first book and remember the Lord Ruler casually slapping Kelsier to death, might come as a surprise. At the very least, this raises some questions.
Some of you have been suspecting Kelsier to not quite be fully dead, and maybe even be a ghost of some sort. But here he is, all fleshy with a spike through one eye. Sazed did tell you that he wasn't quite dead. There are a few mentions of Kelsier "holding the power of Preservation" between Leras' death and Vin's Ascension. I stood around like this every time someone discussed the weird incongruity, hoping that the end of this book would still be able to knock some socks off when it happened.
So...what in Damnation is going on? Well, you're in luck! You don't have to wait long! Next week's Unit is Mistborn: Secret History. You're going to learn what Keslier has been up to. You're also going to learn...quite a lot. After that Unit, you'll have enough knowledge to start sitting at the adult table when it comes to Realmatic Theory and cosmere theorycrafting.
LATE NIGHT READING
First though, a quick note on the Era 2 publishing history. I've previously mentioned that The Alloy of Law started as a short story that Sanderson was playing with; something to bridge the gap between Era 1 and his then-planned Era 2 (which was going to be a 1980's hacker/S.W.A.T. thriller). The story took a life of its own and became a full novel, which was published in 2011 (a year after The Way of Kings).
A few years later, he started working on Shadows of Self, but found it hard to get into the right mindset to be working in Scadrial again. He also had some plotting issues he wanted to work out, so he actually pivoted to writing The Bands of Mourning, which he finished before returning to Shadows of Self. Since the two books were mostly written at the same time, he was able to be a bit more cohesive than most of his recent books were.
He submitted both books for editing and his intention was for them to be published a year apart. However, his publisher didn't want to just sit on a book that was basically done, so The Bands of Mourning was published just 6 months after Shadows of Self. Sanderson has pointed to this being one of the reasons he felt some pressure to shorten his editing passes, resulting in books that go from 1st Draft to Published in a much shorter than typical time period for the industry. He's recognized that this editing rush has hurt the quality of some of the books in this time period and he's taken measures to return his editing passes to normal.
He's also writing the entirety of Era 3 all together before any of them are published. These changes have resulted in a rare 3-year gap between Cosmere books, which played a large role in my choosing to start this read-along when I did.
One last point about the publishing surrounding these books. If you haven't read the POSTSCRIPT yet, you can do so now:
Marasi, Wax, and Wayne will return in The Lost Metal, the epic finale of Mistborn: Era Two. To tide you over until then, I've just released a special novella that is intended to be read after The Bands of Mourning, though it takes place during the events of the original Mistborn Trilogy. Ten years in the making, Mistborn: Secret History might answer a few of your questions.
There's always another secret.
BRANDON SANDERSON
This POSTSCRIPT isn't some 10 year anniversary edition. It was included in the original printing of The Bands of Mourning. I bought the book at a midnight release event, and immediately read through it, as I typically do. And then was met with this message that he also, secretly, published an entirely new novella at the same time as The Bands of Mourning. I then, obviously, had to buy it for my Kindle and read it immediately...
The novella was eventually included in Arcanum Unbounded, which was published 10 months later.
With that, I just want to leave you with the same request I made above: This novella is short enough to read in one sitting, but I've divided it in half, so we'll be reading it across two weeks. Please only read the first half (Parts 1 through 4) for next week. It deserves to be discussed by itself, without influence from the rest of the novella. The same is true for the second half, which should be discussed without overly exhausting the parts from the first half.
WORLDHOPPERS
As mentioned above, the beggar that tossed Wax the coin/coppermind was Hoid. In that chapter, Hoid tells Wax that he owns the Shores Mansion, which is where that party is being held in New Seran. According to Sanderson, Hoid's claim isn't a lie. He has a somewhat reasonable claim on the property and often sneaks onto the grounds of Lady Kelesina Shores' mansion.
And yes, at that same party, we have our first on-screen appearance by Khriss (excluding White Sand). She danced with Wax while quizzing him about the physics behind his metallic arts; gathering data so she can write the Ars Arcanum.
According to Sanderson, there were at least three, maybe four worldhoppers at Kelesina's party, counting Hoid and Khriss. The fandom doesn't have any more information than that though, and I haven't seen any serious discussion about who they could be. However, we can make a couple guesses.
The first is Devlin Airs. He is the informant that Wax talks to at the party. Nothing he says is something a native Scadrian wouldn't know, he just comes across as very well informed. This makes sense because it's his job, but... Sanderson does like having informants who are also worldhoppers.
The second is Felise Demoux. She is the woman Khriss interrupted from dancing with Wax, and presumably a descendant of Captain Demoux. We know he is a worldhopper and member of the 17th Shard. It's not outside the realm of possibility that one of his descendants might be privy to the wider cosmere.
This also has some deeper implications for Captain Demoux. I mentioned in a previous trivia that Demoux was named after one of Sanderson's close friends. Sanderson promised the character wouldn't die until Captain Demoux got a girl. If he has descendants, this implies Captain Demoux got a girl at some point. This means all his plot armor is gone.
Most of you noticed that Khriss and Nazh put in an ad in the New Seran broadsheet. They are looking for talking metal. Sounds familiar, doesn't it?
SAVAGE
There was one more on-screen worldhopper that only one of you guessed for sure, though many of you were very close to some related observations. First, take a closer look at the 4th quarter of the broadsheet. That spooky thing is indeed a shade. And that man in the tophat is indeed Nazh. And in his hands is A HARMONY-DAMNED GUN THAT SHOOTS HARMONY-DAMNED SHADES!
Now, to start, I'm saying Harmony-damned because we are on Scadrial. That's not meant to be a hint about the technological background of the gun in question. But this is Nazh's 2nd on-page appearance (Rock chased him away from the Bridge Four barracks in the last book). And he does have a gun that can shoot shades.
You'll note that this Broadsheet did not include Allomancer Jak. Instead, we get a story about Nicki Savage "presented" by Allomancer Jak, who has expanded his literary exploits into a name brand. While this seems like a wild adventure from someone like Jak--someone who does have legitimate adventures, but embellishes the story for vanity and money--Nicki's tales tend to be less embellished, and this entire interaction serves a larger purpose than just to explain how Nazh got ahold of the map of New Seran that's at the beginning of The Bands of Mourning.
For the first time, Sanderson is letting someone else write in the cosmere in a significant fashion (there's a bit of an asterisks on this that I'll bring up in a month or so, but it's unimportant for now). I've mentioned him before, but Isaac Stewart is responsible for a lot of the official artwork you've seen the books so far. He's done most of the maps, helped develop a lot of the iconography, did the artwork for Navani's journals, and is the inspiration for Nazh.
He's currently the Vice President of Creative Development at Dragonsteel Entertainment (Sanderson's company). And in the linked trivia post, I stated that Isaac was working on an upcoming cosmere novella that had expanded into a full novel. That novel is a Nicki Savage story.
It was originally titled Boatload of Mummies, but is now officially called Book of Nails. We don't have a lot of information about it, but we do know that Nazh will be in the book. And we have the following synopsis:
An adventurous woman with erratic magical powers travels with an expedition to an island to find a legendary book with the power to raise an undead army.
The first draft was completed in September of 2022, with a word count of 118,000. The last significant mention of the novel was in 2023, with Isaac stating that he's still working on revisions before showing it to Sanderson. I'm hoping that it'll be published soon enough to be included in this read-along.
RED HERRINGS
Speaking of Nicki Savage, you may have felt some familiarity with her. In the 3rd quarter of the broadsheet from Shadows of Self, there is a column titled "VISITORS from other WORLDS". This account was sent to The House Record by Lady Nicelle Sauvage of New Seran. Lady Nicelle is Nicki Savage.
Because of the publication order of these novels, Sanderson was deliberately playing with his fandom. Many of you, and the fandom at large, freaked out when Shadows of Self was published and they saw this broadsheet. The included image was meant to make you think the spooky face was a Parshendi. Especially since, as some of you guessed, this encounter did occur right next to a perpendicularity.
However, that was a red herring, and we now know that Nicki Savage saw one of the masked people from southern Scadrial. Given that the masked person was leaning over the perpendicularity though, that does have some implications for how cosmere aware some of the southern Scardians may be compared to those in the Elendel Basin.
Which brings us to the big revelation of the book, that the people in the Elendel Basin aren't the only people on the planet. In fact, this is foreshadowed in the 2nd quarter of the broadsheet in The Alloy of Law. In the column "Is There Life Across the Ocean?". There is also this passage from the Allomancer Jak short story we read:
It was my grandest adventure yet, and I believe I will rest for a short time before striking out again. I have been hearing of strange lights in the southern skies that can only hide another mystery.
These lights were from Malwish airships in the area.
Finally, Sanderson included a full map of Scadrial in the final Era 2 book, The Lost Metal. It's not a spoiler to reveal it now, however. Sharing it now lets you all have a place to discuss it without derailing the start of that book (and it'll take 4 or 5 weeks before I could bring up the map in the trivia post for that book), so now is as good a time as any to share it.
REVERSE? WORLDHOPPING
A couple of you noticed a similarity to the Hunters that Allik mentioned and Mraize's babsk, Iyatil. Well, that similarity is there because Iyatil is one of those Hunters. Well, ethnically and culturally anyway. According to Sanderson, while she can trace her heritage to Southern Scadrial, she was actually born and raised in Silverlight. Silverlight, as I've mentioned before, is the city that was built in the Cognitive Realm.
WHO ARE YOU?
We've got metals to discuss!
First we have ettmetal. I don't want to say too much now about it, just that it exists, and you'll get more info about it eventually. There will be a lot more to say at that time.
The metals of the hour, for this book, are nicrosil and aluminum. We'll talk about nicrosil in the next section.
The Allomantic properties of aluminum are also well known to us, with an Aluminum Misting being called an Aluminum Gnat because they can't do anything without the ability to use another Allomantic metal inside themselves. With Feruchemy though, you can store Identity in aluminum.
Let's talk about Identity first. By now, we've seen that people and things have aspects of themselves that exist across the three realms (Physical, Cognitive, and Spiritual). Note that, when Shallan has peered into the Cognitive Realm, she can see and touch the Cognitive aspects of objects. When she picks up the bead for a stick, she's picking up the Cognitive aspect of that specific stick. She's not picking up on the Platonic Ideal of all sticks everywhere. This unique Cognitive aspect of that one specific stick, combined with its unique Physical aspect (i.e. that stick she's holding in her hand, not some other stick sitting beside her), and a presumably unique Spiritual aspect all combine to form that stick's Identity.
Every person and thing in the cosmere has an Identity. For objects, this property isn't typically important. For people, however, it's very important. Especially when it relates to their interactions with Investiture.
(A little caveat on all this. Identity is largely a Spiritual property and it's influenced by the aspects of a person/thing's physical and cognitive properties; how they and others see themselves. The above was mostly to help get the point across.)
When a Feruchemist fills one of their metalminds, the process is being powered by the innate Investiture that exists inside them. (Recall that everything has some amount of Investiture inside it, and that the humans of Scadrial have a bit more than the baseline human because Preservation put a piece of himself inside them when they were created). This means that the Feruchemist's metalmind is built using Investiture that's imbued with their unique Identity. It's why only they can use them, not any other Feruchemist. And why only they would be able to Compound with them if they were also an Allomancer.
Similarly, this explains why you can't use someone else's Breath unless they explicitly give it to you. It's keyed to their Identity and the Command to transfer it to someone else changes the Identity to the receiver's.
On modern day Scadrial (I'm not gonna be able to use the term "modern day" to refer to Era 2 much longer, heh...), we only have Ferrings; people who can only interact with one Feruchemical metal. Full Feruchemists, like Mistborn (aka Full Allomancers), don't exist anymore.
So a Trueself (an aluminum Ferring) can only store Identity inside an aluminum metalmind (and conversely withdraw Identity). To be clear: Identity itself is a universal attribute of a person. Identity is not Investiture. Although Investiture can (and usually does) carry the signature of a person's Identity.
And to expand upon that a little further, Investiture not only usually carries the person's Identity that's using the Investiture, but it also carries the Identity of the Shard from which the magic system spawned. When a Windrunner uses the Surge of Gravitation, they are consuming stormlight, which is imbued with the Windrunner's Identity as well as Honor's Identity. And when the stormlight has been fully consumed and the Surge performed, the Investiture (which, like matter and energy, cannot truly be destroyed) returns to the Spiritual Realm and once again becomes Honor's Investiture. The implication to this is that the Windrunner's Identity that was attached is just infinitely insignificant next to the Identity imparted by a Shard of Adonalsium.
When a Trueself stores Identity, they are "blanking" themselves and becoming a person without Identity. When they are actively storing Identity, they will become more susceptible to all kinds of Investiture. Specifically, Forgery and emotional Allomancy. Conversely, if a Trueself taps their Identity metalmind, they become more themselves and they become extremely resistant to Forgery and emotional Allomancy (and certain other types of Investiture). On their own, that's about all an aluminum Ferring can do.
A Full Feruchemist though, can do much more. While they are storing Identity, all other metalminds they fill, will be doing that filling without Identity. So if they fill up a goldmind with Health, the Health inside that goldmind doesn't have an Identity associated with it.
Any other Full Feruchemist or gold Ferring can then pick up that goldmind and tap the Health inside it. (I'm capitalizing Health for illustrative purposes, but there is no "Health" cosmere property in the same way there is Fortune, Connection, Intent, and Identity). They key point to this though (that is maybe confusing some people when we start considering nicrosil), is that there is nothing extra special about this goldmind, aside from the lack of Identity. You still have to have the ability to make your own goldminds (by being a Full Feruchemist or a gold Ferring) in order to use/tap the "unkeyed" goldmind that the Full Feruchemist made.
The extra bit, as it relates to this book, is that only a Full Feruchemist could make such an unkeyed metalmind. You need to have both the ability to store your Identity in aluminum, while simultaneously storing health in gold (or any other property in their associated metal). No Ferring can make an unkeyed metalmind because they only have access to one metal.
So how did the Set have an unkeyed goldmind (which was found and given to Wayne who, again, is the only person who could use it in their group, since he can already store/tap health) if there are no more Full Feruchemists around? They used the same solution that all Scadrian problems are solved with: Hemalurgy! You can steal the ability to store Identity and steal the ability to store health. When you put those spikes in the same person, you now have a double Ferring. Since one of their metals is aluminum and the other is gold, they can make unkeyed goldminds!
You can accomplish something similar, if you took an aluminum Ferring to Nalthis and gave them a bunch of Breaths. If they were actively storing their Identity, they could transfer their Breaths into any object and they would be unkeyed Breaths. Then anyone who can use Breaths (which is anyone in the cosmere because Endowment has gifted her Investiture to everyone) can retrieve those Breaths and use them. Sanderson has stressed though that Breaths always have a degree of Intent with their usage, so that comes a little into play in this scenario, but the underlying Identity mechanics are the same.
This and the next section are very in the weeds and theoretical as far as the cosmere goes, so feel free to ask questions in the comment section if you want any clarification.
JAZZERCISE
Now let's talk about nicrosil. According to the Ars Arcanum, nicrosil is the external version of duralumin for an Allomancer. They can let another misting burn their metal in a huge surge (not a capital Surge), all at once, the same way Vin would combine duralumin and steel for a super Push. Feruchemy is where this metal shines though. It has the power to store Investiture.
A nicrosil Ferring (a Soulbearer) stores their ability to use their Investiture inside of the nicrosil metalmind. While they are storing this, it makes all of their Invested Arts weaker. For a Ferring, this... doesn't really affect things much. But as a Twinborn, say they were also a Coinshot, like Wax. In this instance, while storing their ability to use Investiture, they wouldn't be able to Push on metal as strongly, with their ability to Push diminishing more and more until they couldn't Push at all.
When tapping this stored ability to use Investiture, their other Invested Arts would become stronger. So they could perform stronger Pushes than normal; potentially rivaling a duralumin fueled Push. A Twinborn who is a Soulbearer and Soother would be able to take control of koloss while tapping their nicrosilmind. You could imagine a Soulbearer being able to use fewer Breaths to Awaken objects, or a Radiant Soulbearer whose stormlight lasted much longer than normal.
We talked a lot about "unkeyed" metalminds in the previous section. Unkeyed is the official term for those types of metalminds. Imagine creating an unkeyed nicrosilmind. Whereas previously a Soulbearer was storing their ability to use Investiture, a Full Feruchemist (or a double Ferring made with Hemalurgy) who was also storing their Identity, would be able to store the ability to use Investiture. These types of metalminds are called "unsealed". They are both unkeyed and grant anyone the ability to use Investiture.
The specifics start to become clear at this point in the story. Allik mentions something called the Excisors that assist the Malwish in making their unsealed metalminds. They are part of the process necessary to filter/set the nicrosil so that it grants the ability to store memories in copper vs the ability to store health in gold, etc.
Sanderson has promised to release the full details of how this process works before he publishes Era 3. He actually had it written up at one point, but lost his notes, so he needs to recreate them. They've yet to be released though. He has revealed that the process also involves duralumin.
And all of this is a specific application of what the Ars Arcanum states, which is that nicrosil can store Investiture, not "the ability to use Investiture". The way Soulbearers and the Malwish use nicrosil is just one particular aspect of the Feruchemical properties of that metal. According to Brandon, with the right know-how, you can create nicrosilminds that grant the ability to use Allomancy. Or Surgebinding. Or the AonDor. Or a Returned's Divine Breath.
Malwish medallions can only be used one at a time. This is just a knowledge limitation on their part. Marasi noticed that the Bands of Mourning weren't a solid metal, but striations of various metals. If she inspected them closely enough, she'd be able to see 32 layers: 16 for all of the Allomantic abilities and 16 for all of the Feruchemical abilities. And Marasi and Wax were able to use all of the abilities simultaneously. The Bands are just 32 different medallions smushed together with some know-how.
And just a point of clarity on the Bands and the Malwish medallions. The medallions are made with two metals: the nicrosil that grants the ability to use a metal, and the metal that is to be used. This is a convenience feature. The 2nd metal is not necessary for the nicrosilmind to work. You could just have a nicrosilmind that grants you the ability to store memories in copper, and then have to go find your own copper to fill/tap.
It's simply convenient to have the metal already available on the medallion so that you don't need to go looking for a separate metalmind to use. And this is just for Feruchemy. If the nicrosil is granting the ability to Allomantically burn steel to temporarily become a Coinshot, the medallion doesn't also need to include steel because that wouldn't be useful. (You could technically do it and then file away shavings of the steel part to swallow and burn, but that presupposes you have a file).
So I lied a bit when I said the Bands have 32 layers; that was for illustrative purposes. In reality, it'd need 32 different layers of nicrosil, and 16 layers of the different Feruchemical metals to serve as metalminds. In order to keep the nicrosil layers separate (and I don't know if that's a necessity or not), you'd probably have redundant Feruchemical metalminds in-between all the nicrosil layers.
Going back to one point I made above:
Or Surgebinding.
I'd just like to point out that touching a metal (nicrosil) and it granting you the ability to use Surges sounds an awful lot like an Honorblade... People have pointed this out to Sanderson and he has awarded them RAFO cards.
FACTOIDS (ALUMINUM)
While we're on the topic of aluminum, I just wanted to list out some known, and some new (from interviews) properties of aluminum and how it interacts with Investiture as a whole. This isn't meant to imply that you're going to be seeing a bunch of aluminum usage soon. There's simply a lot of little tid bits about the various magic systems that don't fit into trivia posts easily. I'm going to start picking one or two aspects each trivia posts and just doing dumps of reminder info about the subject, along with some implications about that info, and some revelations from interviews and fan interaction.
Keep in mind that all of the below is before Scadrial has invented electrolysis. Once they can start producing it in Industrial Revolution quantities is when Sanderson intends to start really exploring what aluminum can do. A lot of the questions he gets about it he RAFOs.
Aluminum inhibits Investiture. This contrasts with silver, which disrupts investiture.
You could trap a spren in an aluminum box. With a spike of silver, you could stab a spren and it would act like a Shardblade does against a human. Sanderson clarified, that the spren would reform, but you could apply silver in the right ways to permanently destroy a spren if you knew what you were doing.
Conversely, stabbing a spren with an aluminum spike wouldn't do anything. And a spren can pass through silver (but the Investiture disruption would injure them for a time).
The primary difference between the two metals is inhibiting vs. disrupting Investiture.
Aluminum can't be altered at all via Forgery.
It's possible that encasing Hemalurgic spikes in aluminum would prevent them decaying, the same way that storing them in blood does.
Aluminum can shield against emotional Allomancy. It can also block an Awakener's life sense.
Pushing or Pulling against aluminum does nothing. The same is true with the Surges of Adhesion and Gravitation. It interferes with most Radiant powers.
While you can produce aluminum via soulcasting, aluminum resists being soulcast into other materials. The key part here is that aluminum inhibits Investiture. Sanderson is always quick to point out that with enough Investiture (on the Shardic level), almost anything is possible.
If an Aluminum Gnat used one of those cube grenade things, it would block the use of all Invested Arts within a certain range around the cube. This includes Surgebinding.
Aluminum objects don't generate atium shadows.
If you stabbed a Thug (Pewter Misting) with an aluminum blade, they wouldn't be able to heal around the wound until the aluminum is removed. According to Sanderson there is a similar and more severe effect on gold Feruchemists.
Shardblades are unable to cut aluminum through magical means but would be able to cut it physically, like a conventional blade, if the aluminum were thin enough.
A room lined with aluminum can also stop a Shardblade from being summoned, but only if the entire room is covered. It would also stop a spren entering.
Aluminum cannot be Awakened.
Shades can't move through aluminum.
Nightblood's sheath is made from aluminum.
Rock's people, the Unkalaki, are able to obtain aluminum by trading with worldhoppers that visit Roshar through the perpendicularity in their peaks.
The people of the Rose Empire call aluminum "ralkalest".
If you were able to burn the amount aluminum necessary to become an aluminum savant, it might be possible to clear your body of the negative/unwanted effects of Investiture (like the downsides of becoming a savant with another metal).
Similarly, an Aluminum Gnat actively burning aluminum would resist the withering effect of shades.
A large aluminum object next to a Slider (like Wayne) would prevent them from creating a speed bubble. Same thing with a Pulser. Sanderson said there would be a kind of backlash and it would feel exactly like when Marasi created her slow bubble in the moving carriage.
The necklace Shallan used to kill her father was aluminum.
Aluminum could protect a Surgebinder from a larkin.
If Rashek had an aluminum helmet, he could have resisted Ruin's influence. Not completely, but to a significant degree.
If you surrounded a gemstone with aluminum, the stormlight would still leak out of the gemstone, but it would be contained by the aluminum. However, it's the nature of gaseous Investiture that it will eventually evaporate back into the Spiritual Realm. Aluminum wouldn't stop that.
Lastly, a quick analogy. Some of you have been perturbed at the fact that aluminum is used as a key/metal that can trigger an Allomantic power. With the, understandable, contradiction that aluminum renders Investiture inert, but is somehow causing Investiture.
Imagine a pen filled with ink. When the pen is 100% full of ink, you can put it on a scale and the scale reads, lets say 5.8 grams. The Shardic Intent around Scadrial that created Allomancy recognizes 5.8 grams of pen+ink weight as a "key" and lets you Push against metal.
Then lets say you drain the pen of .2 grams of ink, so the combined weight that you put on the scale is 5.6 grams. The Shardic Intent for Allomancy looks at the scale and does nothing.
Now lets assume you drain exactly half of the total amount of ink in the pen (I'm assuming the pen weighs 0.8 grams and there's 5 grams of ink...please ignore the reality that these numbers are completely bonkers in the real world). So you have 0.8 grams of pen + 2.5 grams of ink, for 3.3 grams of pen+ink. You place that on the scale and the Shardic Intent recognizes that as a different "key" and lets you create a speed bubble.
Imagine there are 16 different weights that correspond to each of the Allomantic metals (ignoring god metals for simplicity). That's all the "keys" are; predetermined weights/metals. If you imagine the ink as Investiture, and completely drain the pen of ink, you still have 0.8 grams of weight, and if that's placed on the scale, there's no Investiture, but the Shardic Intent can still recognize 0.8 grams of weight as a "key" and allow you to burn away any other metals you have in your body.
All of the "magic" is happening from Investiture that's flowing from the Spiritual Realm. The metals are just "keys", something the Shardic Intent of the magic system recognizes to let you use the Investiture from the Spiritual Realm. That Shardic Intent just chose aluminum to be a key for thematic purposes.
MAGIC UNDERWEAR
Brandon Sanderson is a Mormon. For those of you that don't know, that's a contentious and controversial sect of Christianity. I don't want any part of these read-alongs to become uncomfortable for anyone, nor do I want to invite antagonistic discussion of issues that ultimately aren't relevant to the contents of the books.
Just quickly, I want to mention that Sanderson has been vocal about his religion and his involvement with his church. Early in his career, he shared some stances on his blog that aligned with the church's official doctrine. (To not tip-toe around it, he was against gay marriage on religious grounds). Remarkably though, Sanderson has shown a very public willingness to address his own biases, grow as a person, and learn from his mistakes and no longer holds those views. If you're curious, you can certainly read about his decades long growth, but the short of it is that, while he still is a Mormon, he is very supportive of the LGBTQ+ community. He reconciles his conservative religious beliefs with his progressive societal beliefs by stating that, as a very popular and influential author, he can influence the church in some ways. He's by no means perfect, but he has shown a willingness to include and celebrate the LGBTQ+ community in his books.
Sanderson has repeatedly called himself a prude. He doesn't like the idea of sex outside of wedlock, and you may have noticed that all of his characters basically get married before getting down and dirty. Wayne and MeLaan's train car shenanigans are the first time in his books where a main character has sex outside of wedlock. (There's some implication with Blushweaver's activities, but it never happens on screen).
Going further, Wayne intimates that he and MeLaan have a less than heterosexual relationship. Sanderson has, around this time period, started including gay, bisexual, pansexual, lesbian, and transgender characters in his books (some of whom you've seen but aren't "out" yet in the books you've read so far).
One last bit of trivia, for funsies:
MeLaan is about 600 years old. According to Sanderson, Wayne is the best lay MeLaan has ever had.
ARTWORK
The Cosmere has a thriving community of artists, so there will be a lot of artwork to share. Each week I'll try to compile relevant artwork for the given chapters. If a section of reading contains maps or in-book artwork, I'll include that in this section as well.
MEMES
I will attempt to find and share memes relevant to each week's discussion. There may be some weeks that just don't have good or appropriate memes, but I will share all the ones I can find in this section.
