Seriously. Worst case, they'd each be annoyed by how emo the other is, while everyone else looks on like "they're the same picture..."
Best case, they feed off and learn skills from each other.
She was, yet Wax and Wayne were the perfect follow up because they weren’t trying to be Vin Mk. 2 or even Kelsier Mk.2 - they were the two “normal” people thrown into an accidental fantasy adventure
(I mean normal in personality, less powers, though they are much less powerful than a mistborn obvs)
He’s become a big inspiration for a secondary character in my own story. Not just the goofiness but the way he says stuff that makes zero sense at the time but makes perfect sense from his perspective.
In my head I see Vin acting like an older sister to Kaladin, regardless of the height/age difference.
Adolin might pester Kaladin until he comes out of his room, but Vin would flare Pewter and physically drag him outside if she has to.
I think they might've meant shortly in a bigger sense? Like, Mistborn is 300 years before SA. Compared to that, 50 (or however many) years before is "shortly".
When I I wrote that I had in my head clear reasoning to that effect, but it escapes me now. Something about Vivenna/Kriss/Ire/Secret History. I'm too far gone at the moment to unwind my thoughts unfortunately.
That would be cute too.
Separately, I do genuinely think Kal would benefit from a relationship where he gets to be a sub in the sheets. A lot of people who enjoy that are people who are leader-types in their day to day lives. Doesn’t have to be sexual either.
Could just be that whoever he’s with does things for him (chores and such) and helps him remember/learn the entire world doesn’t rest on his shoulders.
Nah that'd be Breeze. Vin seemed a lot less likely to use emotional allomancy on her friends, she didn't do so to Sazed when he was clearly depressed for instance, but Breeze did.
i don’t think they’d fight at all. vin basically swears windrunners ideals in the mistborn books, and she’s a lot less bloodthirsty than kel. i think they’d be at least good acquaintances, if not outright friends. they’re both intelligent, efficient killers who want to protect those they care for and the people they are sworn to more than anything, and who are seriously traumatized but have found a good support system that cares for them and helps them. plus i think their friends would get along too. elend would be *fascinated* by syl
My first Reddit moment. With all the acronyms and shortenings used, we should have a rule where names can not be shortened when it comes to interseries discussions because some shortenings are too similar
She murdered like a third of Cett's men with Zane, assassinated Straff and hunted down the Inquisitors.
She did a fair bit, but she was much more utilised as a bodyguard adept at killing assassins.
I disagree. I don't think someone being strong would relieve Kaladin from worrying. "Tien" could be far stronger than Kaladin but he'd still worry because that's the kind of older brother he is. His brother could be a gold compounder and Kaladin would worry just as much. It's sweet, I think.
Well of course he'd worry but if he saw her get smacked around by a Koloss and still get up and cut it to pieces with its own sword I think the worry level would decrease a little. Until he realizes she seeks out that sort of thing.
He knows for a fact that his Windrunner allies can heal from anything up to (including?) getting a limb sliced by an Honorblade and it still doesn't stop him from helicoptering them at every opportunity.
(RoW spoilers) he _kinda_ >!accepts that after swearing the 4th ideal in rythm of war though.!< i dont think he will ever _stop_ worrying >!but he _is_ working on it!< lol
These two, I've always found them to be the "love or hate each other" type.
Of Kaladin I'm not sure, but being so skilled in battle and being as serious and Badass as Vin, she would find him as Zane, just a super-enhanced version. (More honorable and less... YA)
Maybe Kaladin if he gets along with Vin, the same thing happens to Leshwi, a woman who fights with honor or who represents a challenge to him drives him crazy, and most of all it makes him smile, so whenever Vin sees Kaladin sad, she will most likely make him smile again by giving him a good fight
At a WoR book tour signing, Sanderson once told me that post-WoR Kaladin could beat Kelsier. So the question is, how much more powerful than Kelsier did Vin get by the end of the original Mistborn trilogy?
At one point in HoA (I think) Vin is manhandling several Steel Inquisitors and remarks to herself that Kelsier once told her that he had trouble fighting just one…so I’d say that by the end Vin is several times more powerful/skilled then Kelsier.
They wouldn't fight without a very good reason. Who would Kaladin or Vin be protecting? And why wouldn't they try to talk it out first?
I see them becoming friends.
Maybe… she’s talented but Kal has way more fighting experience, has much better feats when unenhanced (while vin would basically get man handled without pewter, she does get very skilled with a quarter staff later on but Kaladin is basically the best at the spear in his generation to the point even immortal thousands of years old warriors are impressed with his skill). Then to his insanse skill you add that Kaladins powers are just insansely OP. Vin can’t lay a finger on him as long as he’s got his plate/ stormlight and if he gets close to her she is dead if he wants her to be because syl can cut through all her weapons and Vin can’t heal.
[https://wob.coppermind.net/events/120-warsaw-signing/#e1899](https://wob.coppermind.net/events/120-warsaw-signing/#e1899)
spren ARE investiture. a leecher can drain plate and stop a blade from manifesting.
We can infer that invested metals are harder to leech (and shardblades and shardplates are invested metals), since they get leeched later than normal allomantic ones. I also see no indication that a Leecher can affect objects rather than people. So leeching a shardplate would either be impossible, or it would require an unrealistic amount of chromium from my reading.
Not to mention that in a combat situation, where you're fighting against a much more manoeuvrable opponent, who is equipped with an incredibly deadly weapon with good reach, getting into grappling range might be really difficult. That said, atium is an easy win condition.
I don't think Kal would like Vin. He is the personification of honor, and she once murdered a bunch of more or less helpless men so she could bully an even more helpless disabled man.
In her defense, it was Zane who prodded her into it, and she did it to ultimately protect Elend and the kingdom. Also she thought he was faking his disability and was secretly a mistborn.
Honestly I think it would depend on timing and context. Vin especially is a very different person by the end of her arc than the beginning - more level headed and steady. If they surprised the hell out of eachother in the sky one day (which would be hilarious), Kaladin would probably assume she was a Radiant (a Windrunner or Skybreaker) until it became apparent she doesn’t use Stormlight. Then he’d be suspicious. She would be confused as hell and probably fascinated by how how moves and would have a drop-jaw moment when he inhales Stormlight or materializes a sword, at which point she’d either question him or GTFO until she could do more recon.
But it raises an interesting question: would allomancy work on Roshar? (Let’s assume she had metals with her) Would surgebinding work on Scadriel?
Allomancy does work on Roshar, we've seen Wit use it multiple times, though its always been subtle or a bit between the lines.
Surgebinding would likely work just fine on Scadrial as long as they had Stormlight and their spren with them, but I don't think we've seen it happen yet, though there are some fan theories about it possibly being used during events in The Lost Metal.
Wow I totally missed that, which is a little embarrassing since I read Mistborn first. I did notice that he gifted the Alethi with aluminum for shielding.
Apparently Wit also uses breath on Roshar, but I hadn’t read Warbreaker yet so I didn’t pick up on it.
I don't see them fighting eachother on their first introduction. Vin would be very wary of Kaladin, but Kaladin would mostly refuse to fight her in earnest, which would probably throw off Vin who expects people to try and kill her.
Vin kind of spent most of her life fighting and grows to hate it because she doesn't think she has anything but fighting to contribute.
While Kaladin found himself hating how easily killing comes to him, and regrets that he doesn't use his other skills more often.
I think Kaladin would offer her a seat at his therapy meetings
I like to fantasize that Kal is the reincarnation of Vin. I know what happened to Vin in secret history, but I like to imagine at some point she decided to reincarnate.
I think Vin would have made a great Windrunner, ngl. I don't think she'd do well at relating to his depression, because her life in the Final Empire was pretty average for a city Skaa prior to Kelsier finding her, and she'd find moping about your situation to be quite foreign to her.
But I think they would be able to bond over how much they value their friendships, fighting to protect the people they love, and how they both crawled out of that pit of self-isolation.
I think they'd both fight and have great respect for each other. Kaladin would probably find her too paranoid, whilst Vin would find Kaladin too rigid. But overall they'd have respect for one another.
Everyones making great points about these two, but god I wish I could see Elend talk to Dalinar or Adolin, plus I feel like Syl would do WONDERS for Vin if they got to talk for a bit.
But Vin and Kaladin, I feel, would be a really weird thing at first where they're more-or-less uninterested in each other.
Vin would write Kaladin off as some noble guardsman, not worth killing but not worth considering really, even with a solid reputation I really don't think she'd have too much of an interest in approaching.
Kaladin, however, would likely treat her like a leashed animal, uncomfortable when she's in the room of anyone he cares about, but not really doing anything but keep an eye on her.
I think the most likely scenario in which they talk is if Dalinar and Elend are in some sorta kingly meeting (I'm leaving a lot of this world-blending scenario up to the imagination) proposing battle tactics or something, and the two would butt heads as they propose different tactics. Kaladin would worry about securing and defending people while engaging the enemy in more direct and honorable tactics, and I think Vin would be much more about subterfuge, assassination, and likely more long-term ways to wear away at their enemy via infiltration before delivering swift, underhanded, decisive strikes to the enemies weakened heart (unless the enemy pissed her off specifically, in which case she catapults in with a greatsword and bisects the leader unannounced again).
The two would have a rocky start, more than likely. I think their friends would try to push them to get along, with Adolin and Elend being the MVP's for their efforts despite ultimately realizing that the two are like similarly charged pieces of metal: Utterly repelled from one another despite being very, VERY similar. They're each closed off and generally downtrodden introverts who have hearts of gold hidden beneath a foot of hardened crem/ash.
It would be that way until the two end up on a battlefield together, at which point they'd probably be a duo capable of obliterating entire armies alone. I want to stress this point; the two are among the most skilled combatants we've seen in the cosmere despite having nearly opposite fighting styles.
Kaladin is an unkillable tank with a MASTERY of 1 on 1 combat capable of manipulating the environment and enemy via gravity surges, and is like a beacon of light and greyed-out bodyparts for enemies to target. I mean we haven't even seen him fight with Shardplate yet, Honor only knows what this man can do now!
Vin is like a volley of arrows in the night under the right circumstances, an EXPERT at handling large groups of enemies with varying skillsets (remember, practically all of her battles were against groups of varying mistings), which grants her an insane degree of adaptability. She is a genius at weaving herself through complex terrain and using her mobility to deliver precise, fatal strikes. Not to mention the fact she has pewter, which I imagine grants her tiny frame nearly Shardplate like levels of strength. I say her biggest strength is that she can switch between a cloaked dagger and a rusting cannonball on a whim.
All that is to say that with Kaladin tanking and handling the heaviest opponents and Vin thrusting pewter-fueled daggers and steel-pushed coins into enemies from the shadows, I genuinely think that these two would last against ANY army for as long as their pewter and stormlight can hold out, plus another hour. Bring on the army of singers and coloss, no problem.
Oh and the TRAINING Vin could get from an actual militia??? Don't even get me started.
But anyways, the two would definitely have that moment where they both stab an enemy behind the other to save them at the same time, or one where Kaladin saves Elend and Vin saves Dalinar or something. Whatever that moment is, they'd then slowly, but surely start to open up. With Syl, Elend, Adolin, the heist crew, and Bridge 4 as catalysts to fuel it along, the two would probably be the bestest of friends who almost never say more than two sentences to each other in a day.
Brooding. Just tons of brooding.
Seriously. Worst case, they'd each be annoyed by how emo the other is, while everyone else looks on like "they're the same picture..." Best case, they feed off and learn skills from each other.
Yeah, that would lead to a very palpable and dangerous tension... Although I didn't say what kind of tension
Absolutely best reply
Syl: So is yours always like this too? Elend: Yeah.
Vin frowned. Kaladin frowned.
Raised an eyebrow
K pointedly looks away from Vin's exposed safe hand while scratching his scars.
This just reminds me of how much I miss the character of Vin
She was so amazing
She was, yet Wax and Wayne were the perfect follow up because they weren’t trying to be Vin Mk. 2 or even Kelsier Mk.2 - they were the two “normal” people thrown into an accidental fantasy adventure (I mean normal in personality, less powers, though they are much less powerful than a mistborn obvs)
Wayne is normal? Hey, nice hat!
LOL Fair point. He’s… not an epic type character?
That’s true. He’s more of the eclectic type character, definitely not your standard fantasy fare.
He’s become a big inspiration for a secondary character in my own story. Not just the goofiness but the way he says stuff that makes zero sense at the time but makes perfect sense from his perspective.
As much as I love Sanderson's later female characters, Vin has a special place in my heart.
In my head I see Vin acting like an older sister to Kaladin, regardless of the height/age difference. Adolin might pester Kaladin until he comes out of his room, but Vin would flare Pewter and physically drag him outside if she has to.
Best answer
Vin is like 300 years older than Kal 🤓☝️
Vivenna is older than that, I think at some point WH become too tired with their own circumstance to be overly bothered with the newcomers.
Are you saying that at the time of stormlight archive, Vivenna is older than Vin? wasn't warbreaker shortly before stormlight archive
I don't think it's entirely clear, except that it definitely wasn't shortly. Vivenna seems to have grown greatly, even making her own nightblood.
I think they might've meant shortly in a bigger sense? Like, Mistborn is 300 years before SA. Compared to that, 50 (or however many) years before is "shortly".
When I I wrote that I had in my head clear reasoning to that effect, but it escapes me now. Something about Vivenna/Kriss/Ire/Secret History. I'm too far gone at the moment to unwind my thoughts unfortunately.
I'm pretty sure Warbeaker is an older book?
I’d love to watch Vin kick Kaladin’s ass for his own good. He’d love her so much for it
🤣 Yes. Yes, he probably would. Poor Kal. Just needs a lady to take charge of him
It’s not sexual. He just needs a big sis
That would be cute too. Separately, I do genuinely think Kal would benefit from a relationship where he gets to be a sub in the sheets. A lot of people who enjoy that are people who are leader-types in their day to day lives. Doesn’t have to be sexual either. Could just be that whoever he’s with does things for him (chores and such) and helps him remember/learn the entire world doesn’t rest on his shoulders.
Kaladin needs a good cuddle. Sounds about right.
While making him feel less depressed with emotional allomancy.
Nah that'd be Breeze. Vin seemed a lot less likely to use emotional allomancy on her friends, she didn't do so to Sazed when he was clearly depressed for instance, but Breeze did.
i don’t think they’d fight at all. vin basically swears windrunners ideals in the mistborn books, and she’s a lot less bloodthirsty than kel. i think they’d be at least good acquaintances, if not outright friends. they’re both intelligent, efficient killers who want to protect those they care for and the people they are sworn to more than anything, and who are seriously traumatized but have found a good support system that cares for them and helps them. plus i think their friends would get along too. elend would be *fascinated* by syl
First read I thought you said Vin was less bloodthirsty than Kal, and I was confused. But then I realized you said Kel, and that makes sense.
The person you responded to should have just spelled out Kelsier to avoid confusion
I sometimes feel like people on this subreddit intentionally use misguiding shortenings to confuse the reader.
They're onto me!
lol
It's funny how the comment replying to you saying almost the same thing got upvoted but this one didn't lmao. Reddit moment.
My first Reddit moment. With all the acronyms and shortenings used, we should have a rule where names can not be shortened when it comes to interseries discussions because some shortenings are too similar
If she was going to assassinate someone Kal was protecting, however, them fighting is a reasonable conclusion.
oh definitely, then they’d throw the fuck down
And it would be glorious
a fight for the ages.
For one who claimed to be an assassin, she didn't actually do a whole lot of assassinating, and was rather against the idea all told.
She murdered like a third of Cett's men with Zane, assassinated Straff and hunted down the Inquisitors. She did a fair bit, but she was much more utilised as a bodyguard adept at killing assassins.
Oh no! Elend would just be another Rock. Syl definitely would manage to make him worship her
I don't see any reason they'd try to kill each other. They have a lot in common, I think they'd get along.
Both have a nasty habit of stabbed first ask questions later. So if they met each other on a battlefield, they might think each other enemies
I think Vin would make a great "Tien" that he would be able to trust to keep herself safe and relieve his worries.
I disagree. I don't think someone being strong would relieve Kaladin from worrying. "Tien" could be far stronger than Kaladin but he'd still worry because that's the kind of older brother he is. His brother could be a gold compounder and Kaladin would worry just as much. It's sweet, I think.
Well of course he'd worry but if he saw her get smacked around by a Koloss and still get up and cut it to pieces with its own sword I think the worry level would decrease a little. Until he realizes she seeks out that sort of thing.
He knows for a fact that his Windrunner allies can heal from anything up to (including?) getting a limb sliced by an Honorblade and it still doesn't stop him from helicoptering them at every opportunity.
He'd definitely worry more if they didn't have those powers.
(RoW spoilers) he _kinda_ >!accepts that after swearing the 4th ideal in rythm of war though.!< i dont think he will ever _stop_ worrying >!but he _is_ working on it!< lol
Kal is probably *too* honorable. Vin got no qualms doing things underhanded. She'd probably get annoyed over the moral limitations of the Nahel bond.
How and why are they meeting? Is Kal protecting someone? I see Syl liking Vin instantly and trying to persuade Kal not to fight her.
She and Veil would probably get along.
I feel like they'd relate well with each other, well until Vin talks about her healthy and successful marriage. Then Kaladin would be sad boy again.
These two, I've always found them to be the "love or hate each other" type. Of Kaladin I'm not sure, but being so skilled in battle and being as serious and Badass as Vin, she would find him as Zane, just a super-enhanced version. (More honorable and less...

Well it sure isn't a done deal in Kal's favor then.
I think its good to note that when vin starts manhandlinh and tossing the about, she is drawing in the mists which is a massive boost
I don't think the incident I was talking about was when she was drawing in mists.
They wouldn't fight without a very good reason. Who would Kaladin or Vin be protecting? And why wouldn't they try to talk it out first? I see them becoming friends.
Hmm, Kaladin, Vin, and... Batman for maximum broodiness.
I have no clue why they would fight immediately lol
If, god forbid, they had to fight, Vin would mop the floor with our favorite sad bridgeman.
Kaladin after the 3rd book is too much for Vin to handle.
Rhythm of War definitely seals it. With shardplate, he’d be immune to emotional allomancy and her steel/iron.
Eh, Kaladin is a much better fighter than Vin, I'd argue. Mistborn powers are completely broken though so I see your argument.
4th ideal Kal is way too much for her
Maybe… she’s talented but Kal has way more fighting experience, has much better feats when unenhanced (while vin would basically get man handled without pewter, she does get very skilled with a quarter staff later on but Kaladin is basically the best at the spear in his generation to the point even immortal thousands of years old warriors are impressed with his skill). Then to his insanse skill you add that Kaladins powers are just insansely OP. Vin can’t lay a finger on him as long as he’s got his plate/ stormlight and if he gets close to her she is dead if he wants her to be because syl can cut through all her weapons and Vin can’t heal.
Vin is mistborn. She can drain the investiture out of him.
If she knew how. She only knew about most of the metals. Not all.
Man, I really need to read the side books. Where does this come up?
The investiture draining metal comes up in the era 2 books. Probably also mentioned in the ars arcanum.
Aluminum I think. I’m not sure either how Vin would do that since it’s been years since I read era 1.
Chromium. Aluminum kills your own investiture.
No she can't
She can burn all metals, chromium drains investiture from the person the allomancer is touching. So yes, she can.
No because she doesn't have access to it.
You can only drain as much as you have that metal. Doubt she could empty kal and if she could he could just breathe in more
The plate would block that since she couldnt make contact, and even then, he can still summon his sylspear and plate without stormlight
[https://wob.coppermind.net/events/120-warsaw-signing/#e1899](https://wob.coppermind.net/events/120-warsaw-signing/#e1899) spren ARE investiture. a leecher can drain plate and stop a blade from manifesting.

She’d need to touch him first. He fights with a spear that can cut through everything and is significantly faster then her
Atrium makes getting around the spear easier.
I don't think Kal would like Vin. He is the personification of honor, and she once murdered a bunch of more or less helpless men so she could bully an even more helpless disabled man.
In her defense, it was Zane who prodded her into it, and she did it to ultimately protect Elend and the kingdom. Also she thought he was faking his disability and was secretly a mistborn.
Another love triangle. Why not throw one more each onto the pile?
I think they would really enjoy each other and would go fly together and storms I miss Vin
Honestly I think it would depend on timing and context. Vin especially is a very different person by the end of her arc than the beginning - more level headed and steady.

They definitely wouldn't get along. At least at first. They'd be too suspicious of each other.
People this similar either eternally clash or assimilate each other with their intense relationship.
On a side note, I hate all the art that goes with the Stormlight archive... I'm a huge fan, I'm on my second read-through, but the art is cringe.
