Kaladin’s yellowish-red eyes...

[Gloomspren]

Sorry if this has been mentioned before, but i couldn’t find a thread on it. Chapter 106 kaladin breaks as a result of teft’s death and... then kills the pursuer horrifically. But a few things interest me here. Venli says:

Quote

His eyes were flowing like a Radiant’s, his face a mask of pain and anguish, but the eyes... she swore the light had a yellowish-red cast to it. Like... like...

Like what Venli??? It doesn’t sound like void light?? But perhaps it is something about odium?? Or just a general corruption? But with all the light theory in this book it seems to not fit any categories.

Quote

Kaladin didn’t attack. Instead he reacted down and infused the ground, but with power that didn’t glow as strong as she thought it should.

Kaladin also says he only has a vague memory of killing the pursuer and can’t think straight, and then proceeds to jump off the tower.
 

So moash earlier had said that kaladin could either embrace odium’s emotion taking powers or could kill himself, and he did... both? Not sure if this whole thing is a consequence of him getting too far from the oaths (hence his reduced lashing ability), and if all radiants when they’re about to give up get a yellowish red cast to their glow but... I’m interested to hear other’s thoughts on this. 
 

what the heck does yellowish-red mean??

[Golstar]

To me yellowish-red sounds like corrupted Odium investiture. Just like Odium can corrupt Honor's investiture, so should the reverse be possible. I think Kaladin co-opted Odium's investiture and tinged it with Honorable intent. It wasn't completely red, as there was still a lot of pure Odium in there.

Golden investiture is also interestingly how Odium's investiture would look if native to Roshar. As mentioned in another post, I think Odium is going native (unintentionally).

Interesting. Honor's power shows blue in the eyes. Odium's power seems to be yellow, unless it's being used to corrupt something. Corrupted Investiture appears red.

Sja Anat corrupts Honor-Cultivation spren and they end up red. Fused are corrupted Singers, who are probably naturally closer to Honor-Cultivations. So red eyes.

With what we're learning about Shard-light, this fits in pretty well. A pure Shard-light (Stormlight being the pure free Investiture of Honor, for example) will appear as the pure color of that Shard. Odium's is yellow. Light that is being smothered/corrupted by the Light of another Shard creates a red color. Black "light" (like the smoke from Nightblood) must be "unattached" Investiture (no Shard's Intent)

Back to Kaladin: if he is giving up on his Oaths slowly, he leaves an opening for Odium to insert himself. His internal battle becomes between his Oaths and letting go completely (Moash-style). This battle is seen in the yellow (Odium Light) and red (Odium corrupting the Honor Light that's fighting).

This would be great to look out for in other characters and situations in the future.

I'm not sure if I'm misremembering and I doubt it would relate to Nightblood, but I'm pretty sure black "light" belongs to Ruin (I'm recalling the black smoke when he escaped from the Well)

[Leuthie]

A quick look says that black smoke is simply corrupted Investiture's Physical manifestation. The Well had black smoke because it was Preservation's Perpendicularity used as Ruin's prison for several millennia. Ruin managed to corrupt some of that power over time.

[Ramona Tehradin]

Finally, we are having a separate discussion on this! 

So, why Kaladin's eyes turned yellowish-red? Hmm...the correct answer is...

Nobody knows. 

But there are theories and it began the moment everyone fell unconscious to Tower's corruption except Kaladin Stormblessed. 

Kaladin remaining awake just because he's 'far enough into his oaths' or 'close to Honor' is a generalized way of saying we freaking don't know. It is weird to know that each individual oaths have their own levels, and if we look into Kal's story from mid-part 3 and part 4, then Kaladin certainly wasn't going 'far enough into his oaths'. His depression was taking control in episodic manner, crippling his insides but Stormblessed never lost his powers. It meant he should be 'going down on his oaths' but that wasn't the case. In fact, he got better to use Adhesion as the story progressed. 

Teft regained his consciousness only when Lift healed him, and he needed a constant supply of Lifelight healing to stay awake or else he'd stumble back into coma. And pretty sure the whole tower was filled with Radiants who have been far along their oaths as well. For example, I heard Stoneward squires present which meant that at least a Stoneward was already into her third Ideal to have squired. Doesn't make sense, does it? 

I think we need a whole new page for that. But remember something has always been different about Kaladin from other radiants. Anyway, let's come back to our yellow-eyes stuff. It's Odium trying to enter his soul. Here is how that goes: 

RoW spoilers: 

Spoiler

• HE (Kaladin) HAS LEFT THE BATTLE, WHICH I HADN’T THOUGHT HIM CAPABLE OF DOING, Odium said. STRANGELY, THIS WILL MAKE HIM FAR MORE DANGEROUS IN THE FUTURE. UNLESS WE ACT.BUT I CANNOT STRIKE HIM DOWN DIRECTLY.NOT UNLESS HE PUTS HIMSELF INTO MY HANDS. 
• I WOULD CLAIM THIS ONE, AS I HAVE CLAIMED YOU, Odium said.
• CAN YOU THINK OF A WAY TO HURT HIM ? Odium asked. DRIVE HIM TOWARD ME ?
•  
  I HAVEN’T THE CONNECTION TO HIM. Odium considered, humming softly to a rhythm. I SEE A WAY. THERE ARE HOLES IN HIS SOUL. SOMEONE COULD GET IN. SOMEONE WHO KNOWS HIM, SOMEONE CONNECTED TO HIM. SOMEONE WHO FEELS AS HE DOES.

- Here Odium refers to his episodic depression which crumples Kaladin's resolve but each time, Kaladin comes out of it and that makes Odium concerned because he has 'foreseen Kaladin doing something dangerous in future which should not happen'. I don't know what Odium saw Kaladin doing but it was dangerous enough to rattle this god and focus him to recruit rather than kill him directly. Think about it, so far Odium didn't think much about Kaladin then why a sudden interest? And why would he want this particular Radiant 'towards' him? 

- The only reason is because Odium understood Dalinar couldn't be defeated by himself, so the best way to defeat him is by using Kaladin as Odium's Champion and he knew this will be successful because I don't think Dalianr would be able to bring himself fight Kaladin and Kaladin is already a force to be reckoned with. 

 

• “He wants me, as he wanted Moash,” Kaladin said. “If he keeps pushing, he’ll have me. So I have to go.”

- This is after his yellow-red eyes thing so we can now know that the fractures in his soul has expanded enough for Odium to Connect with him minutely and corrupt his usage of Investiture. Startling fact is, Kaladin is still in control and he knows as his pain prolongs, the enemy would drive him to become what he feared hence he would destory himself than succumbing to Odium's intent. 

 

• “You may turn in your weapons,” Stormblessed said to the enemy. “And return to your kind unharmed, so long as you promise me one thing.” He smiled. “Tell him that I’m particularly going to enjoy hearing what he looked like when he found out what happened here today.”

- Kaladin defeated Odium's influence over him, pushing back again just like Dalinar had done in Oathbringer. 

• You should not tempt me today, Taravangian! Odium thundered. I have lost my champion again, and now I am bound by an agreement I do not want. How do they know how to move against me? HAVE YOU BETRAYED ME, T ARAVANGIAN ? Have you been speaking to Sja-­anat? WHAT HAVE YOU DONE ?

- This line happened right after Kaladin-Navani regained Urithiru and Dalinar discussed terms with him. It clearly states Odium visioned Kaladin as his champion but failed again. 

 

The moment Teft died, Kal's soul began fracturing and Odium invaded in, trying to tempt Kaladin by taking away his pain and making him feel nothing again. There was a power struggle between the Honor within Kaladin and Odium's temptation and it manifested in form of corrupted Investiture which surprisingly Kaladin was able to control. But corrupted Investiture often exhibits abnormal behaviour in Surges ex. Rlain/Renarin's Futuresight but in case of Kaladin, Honor's true Surges manifested still (another mystery) which meant he was pushing Odium back despite the pain and temptation. People think Kal's resolve will break but I know by far he has one of the strongest will power to combat against anything. 

Oh, and for why Reverse Lashing didn't glow like Gravitation Lashing? It's simple because it doesn't. Here is the explanation: 

Quote

 

A Reverse Lashing didn’t glow as brightly as it should, considering the Stormlight. It was kind of inverted, in a way. 

- When Kaladin was using it to steal Stormlight.

Because the object was infused at molecular levels to act as source of gravity which meant Stormlight was needed to alter fundamental forces of each individual molecular. That would take a great deal of course. 

 

But there are a whole lot of things which make little sense about Kaladin: 

• His spidery senses while trying to avoid Pursuer. 
• His whole remaining conscious since Tower corruption has not been explained properly. 
• The way Cryptics near Elhokar tried to avoid when Kal came near. 'Shadows go away'  
• Kaladin never felt effect of Tower's corruption except 'a growing darkness pressing against him' 
• Kaladin's power kept working even though healing was difficult, in fact his powers kept improving. 
• Why didn't Kaladin's Surges behaved abnormally when Odium Connected to him? Why Honor's true Surge still remained unchanged?
• Reverse Lashing is a combo of Gravitation-Adhesion. Tower put a damp of Gravitation but then how RL still worked?
• The freaking whole Son/Child of Tanavast thing! 
• What the heck did Odium see in future about him? 
• Vyre kept repeating that 'Kaladin Stormblessed can't be killed, he's the force of storms and storm can't be defeated.' X ten times in whole book. Why would he repeart this? What did Odium showed to Vyre?
• The way Kaladin uses his Surges/Windspren to freaking deflect Highstorms!! AHHH HOW is that possible!

In case you are wondering some interim detailed reasons for Kaladin to remain awake during occupation, I have delivered a long reasoning about it in a separate thread. The link's below, do check it out and provide your views.

Scadrial has three magic systems. We didn't learn about all of these until way into the Mistborn books. Some of the more exotic combinations weren't revealed until Era 2. Could there be magic system(s) on Roshar that we don't even know about yet?

1. The whole corruption deal seems different than Surgebinding and Voidbinding. It doesn't involve surges, but instead does strange things to investiture. That some who use it dislike the term corruption indicates there is something deeper.

2. Ars Arcanum says Voidbinding is cousin to Old Magic. That seems a bit weird to me when all we know about Old Magic is that the Boons/Curses of Nightwatcher are related to Old Magic. 

3. Stormlight-powered Surgebinding seems very similar to Allomancy - consuming investiture to do magic. Could there be a Ferruchemy and/or Hemalurgy facsimile? 

4. Perhaps an unknown magic system might involve gaining power through the perception of others? A sort of Living Legend effect, where the idea of Kaladin Stormblessed becomes real. He gains the ability to do what people think he can do. Did the "Kaladin cult" empower him somehow?

5. A champion effect? Is Lift 'Lifeblessed' and Vyre (or El) 'Voidblessed'. Is there a particular magic on Roshar which allows blessing of individuals in a fashion unrelated to Surgebinding and Nahel Bonds (although a blessed might be very likely to attract one).

He wants to look gold for the positive perceptive connotations, corrupting investiture makes red, and Chimeric violet (dark but also saturated violet) is his "true" color. The void that sucks in emotion.

Well, there certainly is a lot of talk about how he (especially pre-pruning) was a larger than life presence. I think Eshonai describes him as almost different species than other humans or "how a human in warform would look" (from memory).

But Kaladin especially seems to have an almost supernatural effect on those around him. Back with Bridge Four he would deflect arrows meant for others subconsciously - but perhaps his bond with his "people" goes further than that? Even Elhokar seems mesmerized by him, and almost immediately wants him as a bodyguard. Kaladin is a brooding, morose man with severe depression and anxiety issues. While great leaders with troublesome minds are not unheard of - he seems to project a different persona than his own. He even thinks about it relatively often - that he feels a disconnect from he projects and his actual self. I realize that his depression and anxiety play a part in this - but I actually think he is partially right.

I almost expect him to just come back if he dies, similar to the fused or the heralds. Incidentally the fused seem to have a similar effect on the singers, and the Pursuer seems pretty focused on his reputation. Maybe his reputation is what gives him his powers? El had his titles stripped as punishment. The heralds (except Ishar) get very upset when people worship them and give them titles. Ishar being venerated as the Almighty might be what allows him to surgebind without having an Honorblade or a spren. I could be reaching, but titles/reputation/perception having power would seem to fit Odium and Honor both, and might be a magic system created by their interactions.

Somehow Navani’s bond with the Sibling generates Towerlight. It’s end-positive.

I’d say Stormlight surgebinding is more like Feruchemy or Hemalurgy. It’s at best end-neutral. You take in Stormlight and use it for effect. You might even describe it as end-negative because Surgebinders aren’t very efficient at holding in Stormlight whereas the Fused are very efficient at holding in Voidlight.

On the other hand, in Allomancy, the metals aren’t the source of Invenstiture, just a focus. The tower fabrial is the focus that Navani and the Sibling use to create and direct Towerlight.

Lift is a weird case, but it seems to be the closest thing we see to Allomancy on Roshar considering she metabolizes food to generate Lifelight to power Surgebinding kind of like burning metals.

I think there are issues with drawing direct parallels but to me it seems more like Towerlight and Lifelight ~ Allomancy, Stormlight ~ Hemalurgy, Voidlight ~ Feruchemy.

This is only when they are powering Surgebinding (unless you count the Towerlight stuff as fabrial Magic separate from surgebinding). I’m not sure where Warlight and the theoretical Cultivation/Odium Light or TripleLight would land. And I don’t know how this would change for Voidbinding or Old Magic.

I feel like Odium needs a couple more colors attributed to him, red yellow and purple is only half of the color wheel after all.  Like maybe if his power crosses with Cultivation it forms a nice shade of teal.  Or if it blends with Harmony's investiture it becomes poop brown like when you combine all the crayons together.  Maybe if you combine Odiumlight with itself it forms a rainbow.  That way we could attribute every possible color in some way to his theoretical influence.

[+Oltux72]

Sja-anat had left Taravangian with a few altered Spren. So where did she go? Urithiru? She had an interest in the Singers escaping and Odium failing. How do the eyes of a Knight Radiant forming a temporary bond with Sja-anat look like?

I don't know if there's consensus on what El's title was, but my first thought was Stormblessed and I'm wondering, if we're looking into titles creating their own power of a sort, if Kal has a title that was formerly associated with a Fused, what does that mean for where he is able to draw power from?

Questioner

So, we know in Mistborn there is this running... you can say, motif about Ruin being associated with the color black and Preservation with the color white, we see a lot of very subtle and a lot of very unsubtle...

Brandon Sanderson

Yeah, yes.

Questioner

Is such a motif present in any other books? I think I see it in Stormlight.

Brandon Sanderson

Yeah, in Stormlight you can see it. So, Ruin is a red-gold... not Ruin, Odium. Odium is a red-gold. Honor is a blue-white and Cultivation is green, obviously. So, those motifs stay, when you... when you see a red or a gold, it's a reddish gold sort of thing, either of those colors, it's going to be Odium.

Questioner

Even when we something we might suspect to be outside influence in other worlds?

Brandon Sanderson

Not necessarily, because red can also mean corrupted Investiture in the Cosmere. So, I would call Odium's real color gold, because you're going to see red when Odium is corrupting other things, so...

Questioner

It's not necessarily on Roshar.

Brandon Sanderson

It's not necessarily Odium. So, you're asking for the invading force on Mistborn, it doesn't necessarily mean Odium because it's red. So red just kind of means corruption. I've talked about that before, so. Not necessarily, not definitive, yeah.

Footnote: When Sanderson said "you're asking about the invading force on Mistborn", the questioner made a guilty "caught red-handed" shrug.

I feel like the book was trying to set up an "oh no, Kaladin is angry and he's going to become Odium's champion" moment, but that's ridiculous.  Maybe it was making the point that Rayse was deluded enough to think he could tempt Kaladin into becoming his champion?

I like this explanation. It fits really well with all the strange stuff about Kaladin. The only part that doesn't seem to fit with this is how he used super speed to kill Helaran, because that was before people knew him.

Kaladin's reputation comes from his actions, and his awesomeness and all that. I doubt that he gains any powers from people's opinions of him, that just seems like it would be out of the blue. Ishar has his Honorblade, which is why he can surgebind. The Defeated One focused on his reputation because he was insane. The Fused get their powers from Odium.

Honor is end-positive, because the powers are entirely external, just like Allomancy.

I have no idea about Odium, but he doesn't seem like end-negative or neutral. Fused and regals are definitely end-positive. 

Cultivation is surprisingly the closest to being end-neutral (possibly fully) even though she has the most end-positive Intent we know of.

End-neutral is, when the power you get, is the same, as the power lost. Feruchemy revolves about storing your attributes for later. 

Old magic revolves around giving up something and getting something else. Taravangian has super smart days and super dumb days(had?). Dalinar lost his memories, to get them back later. Lift burns her own energy reserves, to get Investiture (does she metabolise the food? Sounds like endless sitting on toilets to me....).

The Nahel bond is from Honor. This binds two entities together, enhancing both of them in the process. This is also the focus of power for Radiants. 

Stormlight functions the same way as metals do on Scadrial. It doesn't do anything special by itself, but give it to Radiant who can burn this Investiture to gain abilities just like Mistborn do when burning Metals. That burnt Stormlight also isn't lost forever (what happens to burnt metals? Are they metabolised?). It returns back into spiritual realm, from where it can return into physical trough Perpendicularity. Stormlight can also heal and sustain, which is entirely end-positive.

Your point about about Radiants being end-negative is plainly wrong. They might be inefficient in holding Stormlight, but that doesn't mean that the power is lost. If you cup your hands and try to hold water, you will have leaks. The water that leaks, doesn't just disappear into nothing. It will eventually evaporate to vapor, which will get absorbed back into the atmosphere.

The only truly end-negative thing on Roshar we know of is Nightblood.

Odium is a part of Roshar, Voidlight is still violet, not gold

Odium seems to have multiple colors associated with him:

Gold: Investiture leaking from Rayse, his god-metal (Raysium daggers are described as golden), several visions of Odium
Red: Corrupted/modified spren, various Fused powers
Violet/Stygian: Voidlight, various Fused powers

My personal interpretation is that Shards don't necessarily have a single color, but the investiture they manifest in the physical and cognitive realms are tinted in a unique way for each shard. We've seen on Scadrial that some Shards can even mimic the color of other shards and use this for deception. Probably not a normal occurence, but it shows that there is flexibility.

Red, according to the WoB, is corrupted and/or alien investiture. Un-natural so to speak. Violet and stygian is close enough to this that it can be hard to discern.

Odium is associated with voidlight which is certainly not gold, but there is no doubt that he manifests golden investiture on several occasions. My hypothesis is that the difference is in the manifestation. Voidlight is an almost elemental type of investiture - like stormlight. Mortals can manipulate it and it obeys certain laws and acts predictably. It's a very stable form of investiture. Alternatively, voidlight is special because it was originally manifested as another form of investiture, either stormlight or some kind of 'neutral' light. Then when Odium co-opts it, it becomes violet. Blue+red = violet?

As Odium's god-metal is golden, I suspect that color is associated with objects and people that have been permanently and non-ephemerally invested. Voidlight is consumed and diffuses back to the spiritual realm, like Stormlight. I think a Champion of Odium could very well have golden eyes but use stygian/violet voidlight as fuel.

Investiture can manifest as light, gas, liquid and metal. It's present in all matter, we're told on several occasions (Preservation in particular talks about how it's part of every single animate or inanimate object on Scadrial). Sentience is investiture, we're also told (and the reverse, investiture has an inherent drift towards attaining sentience). Do all these manifestations have to align in color? I don't think so. Shardblades are pure investiture, but can have all kinds of colors. Spren are highly invested - and they display a variety of tints. On Scadrial we have examples of blue investiture aligned with Ruin and/or Preservation - Allomancers see blue lines emanating from metal objects.

So it was wrong that I said Odium's investiture was golden. That's a too limiting description for what we've already been shown - but I think it fits as his primary color (especially due to the god-metal and leaking investiture).

Hmm... then what about Navani's experiments? Odium's Light produced a large band of violet when passing through a prism, and his Light rings with his own pure tone
