When I read the book, I read it all the Jasnah as she already spoke all the required Oaths (maybe all the Oaths at all) and she hides her Plate. Indeed during the battle, it's strongly suggested she used her Plate and dismiss it just after...But I believe it's something she already was capable of. About her Radiancy's level, notice how she reacts to Shallan when she tried to proclame herself as a KR. It's seem to suggest that Jasnah see herself as superior in that context. I read it as she already spoke all the Oaths and this means she is the second full Radiant we saw in the Series in modern times (of course the first is Nale)

I don't understand your color's argument. Awakening needs color...but the color doesn't need to come from the Awakened stuff. He didn't need it, it could just go with Health to heal the damage of oxygen lack. By the way, He could compound also oxygen on the fly if he want

Kelsier is now interelly composed by Preservation's Investiture. I believe that to him becoming a serial killer is something extremelly unlikely. Much more if he is one, with the amount of raw power he would dispose, he will not be able to be stopped by anyone. And I am not talking about his potential fullborn status (that I don't believe he is) but simply his Mistborn's powers+ the degree of Savantism he developed with them. He was already a powerful Mistborn for TFE's standard...Now he is a god among the current allomancers. Of course this assuming he retained his Allomancy post-mortem...This is not sure and indeed Kel could be an Allomancer no more

This is exactly the reason I avoided to explain stuff, maybe he wanted to read it in the future. Spoil the whole stuff is something to avoid unless unrequested (to me)

This not implies the Sibling needs to be bonded to grant his/her purpose into Urithuru. As the Radiants and their Spren need to be relative close to mantain the Bond, an hypotetical Sibling's Radiant can't leave Urithuru without one of those scenario happen: 1) He would lose his powers, exposing a key individual to many treats 2) The Sibling goes with him and Urithuru will litherally die because all its functions will stop. Listen I am not saying, it is in this way...I am just making notice that implication is not an implication but just a possibility. This is the same thing I said, Dalinar's attitude not his profession/hobby was the Radiancy's key (and the same happened with Gavilar before him). Simply "what you like to do" is not relevant for a Nahel Bond, "who you are" matters....Many Lightweavers were artists but because that kind of people often has also artist inclination. Not every Artist will be a Lightweaver's candidate and not only an Artist could become a Lightweaver (just watch Elk). I simply said Navani didn't show any Bondsmith's attitude. I like her as character but I will not faking she is an egoistic person who doesn't place her interests before many others things. We didn't see any Slumbering Spren be awakened by a Bond. Oathbroken Spren has a place of them ripped out and could be restored to a degree (I believe they will be never truly healed without the original Knight) if some other human provides them a good anchor to the physical and is aligned with them. Pattern was never slumbered or something like that. He was fully aware in the CR with his bond with Shallan mostly evaporate. Syl was Oathbroken by Kal and then easily restored. Maya is Oarhbroken (or in a grey zone) and it will be probably hardly restored to a degree by Adolin. None of those cases is applicable to a spren who slowly start to decrease his awareness (I believe it's a decent definition of "Slumbering") Again, I am not saying the theory have to be wrong, simply that it's a speculation and there is not an implication of proof about

nimi is just an honorific not a name, as Szeth doesn't know the name, he calls simply Sword with an honorific, it's like "Mister Sword" ;-) By the way Szeth has two Blades now, one of them is extremelly more useful than the other....and it's his Skybreaker's Blade. The more eloquent one is to use only into specific circumstances as a regular Shardblade does its work well 9/10 of the times, there will be instances where the Black's one is decisive but mainly a Radiant's Blade is more than enough and by the way, it could be used by Szeth as protection while he uses Sword-nimi as offensive tool

Darkside has a suns too, simply it is irradiate by an not visible light. Actually Darkside is full of (and heated by) UV. So Taldain orbits around two binary stars placed into an incredible well calibrated orbid

Hoid is simply not Human anymore. He started as One but some events in his Life turned him into something else. By the way the returning to Yolen in mass for worldhoppers is impossible as you May see the references to the actual impossibility to locate It. Returning to the OP, recently the Red color is discovered to be' caused by a Shard corrupting/hacking another one's magic. So It's possible there is some Shardic manipulations going on in the Scar...malicious or not

Trying to make the Shards fit with the Metallic Arts' metals is something that arose sometime. The attempts to make this are resulting in mostly arbitrary decisions that forgot 1 or 2 of the Metallic Arts. For example I could argue that having see the direct involvment of two godmetals....the mundane metals associated with those Shards are the One more near to the effects of their godmetals. For example pairing Ruin with Electrum. Someone else could try to use the relationship between Shards to fit the metals...so opposite Shards will have paired metals (ex. Ruin-preservation as gold-electrum or cadmius-bendalloy). Still others could try to use the Feruchemical effects to fit this hipotetical table...as you see It's too an arbitrary decisions. Much more the Allomantic Powers were chosen to fit the Need of a thieft crew so It's unlikely for them to be' linked so tighty to the Shards. This without considering the Shattering could has resulted in 16 Shards differently by the one we have

Yeah I know that. Many worldhoppers use a time dilatation technique to extend their Lifespan. What I was saying is if Demoux spent decades on Scadrial raising a family. He would probably be look quite old in SA. But again, that was a tenuos consideration. The relevants arguments were others

As Renarin is bonded with a Corrupted Radiant Spren is hard to define what is normal and what is dictated by the Odium's Corruption. About Dalinar and his Spiritual Adhesion is the result of his Resonance affecting the Surge...no proof yet

@Wit Beyond Measure I believe you misunderstood me. I wasn't deny a link between the Sibling and Urithuru (also if not confirmed yet), I said simply that if the Sibling is the entity that made Urithuru works, He/she be bound to someone is not a requirement for work also as Urithuru's heart. So I could see them made Urithuru to live again as plot relevant...But this not imply someone (Navani or someone else) will bond the Sibling. I also (but here I am not sure if you were answering to me or someone else) said I see all the Navani's passion (pun intended) for Fabrial meaningless for the argument of the Sibling's bond. It's simply not how the Nahel Bond works, Dalinar becomed the Stormfather's radiant not a Stormwarden because his hobby/work is related to the Storms. I don't see her as a Bondsmith type of person, She is a Fabrial expert (and I honestly like her as character) but this doesn't change the relevant things to me. Navani and her team will probably discover something about the Sibling during her researches into Urithuru and maybe they will also be able to awaken him but this doesn't mean that some of them will bond him/her.

Some time ago I wondered if a Shard could invest itself so much to De-Ascend. After talking a bit with the others, we figurated that Investing is probably an osmosis like phenomen and therefore under a certain threeshold it will be impossible to Invest further. Of course that is a speculation but it's the only answer I could give you

After consumption the Lerasium return to Preservation. The guy remains a Mistborn but a Mistborn isn't more invested than someone else. It's just more deeply connected with Preservation

I believe he will uncapable of turning ALL the Investiture into solid form...Probably he would reach a point where He can't invest more. But still there will be so much Lerasium around to turn almost every human into a Mistborn. So you need to imagine a place where Mistborn, Fullborn and Mistborn-Ferring are everywhere. The amount of Atium avaliable would made people able to predict the future to a degree so probably no more Casino or stuff like that. This use of the godmetals will make the power return to Harmony and probably it will unbalance him toward Ruin...not a funny scenario

It's not strictly impossible...But is extremely unlikely for all the reasons I provided before. Much more, I checked and I made a mistake, there is actually the Demoux's house and if they are truly Demoux descendants they have no link with Wax. By the way, I don't understand why Demoux and Aslydin will have to keep secret their offsprings (because your hypotesis has sense only if nobody know that Wax's bloodline was related to them)

There are a couple of things to considerate: - First of all, if the Sibling is the Force that allows Urithuru to properly work (likely), there is no need for him bond with Someone to make the city works. - second, the Bondsmith's Spren are bound like the others by the order's ideals. So regardless of hobby and profession, a Bondsmith need to be in line with the Bondsmith's mantra. So I could see Navani or another One able to find about the Sibling and maybe awake him but this doesn't mean that person is going to bond him. Personally I don't see Navani as a Bondsmith's type, in this Mr. T fits Better the description...but yet It could be' every kind of Person. I also feel unlikely the "three way bond" described in the OP but this is the last issue.

Except the body isn't really gone as it will reform when the Vessel is no more a Vessel (example if he die or give away the Shard) so the body is probably integrated into the Shard itself rather than destroyed. We know also that the power could be splintered also with the Vessel alive (there is a WoB about that I will add later because I can't now) and we saw it at least in one case, with Ruin's stolen power. What Preservation did is to Splinter a portion of Ruin in that circumstance. Probably it's also what happened during the Odium VS Ambition's fight as something of them remained into the Theredody's system in the battle's aftermath.

I honestly don't know the Wax's parents names but I will strongly disagree with the Demoux & Aslydin's part. If if they were his ancestor too. That side of the family will be tained by the mixing genes and over centuries it would be mostly impossible for them to be able to gave offspring to a Feruchemist also, someone so important as Demoux will probably have a House if his bloodline progressed. Wax's grandmother also see the mixing bloodline as an abomination and her attitude is shared among the Terrismen. I believe they will never made her a chief among them if she is one of such abomination By the way, assuming a dinasty after Demoux will implicate they remained on Scadrial for decades and I believe Demoux's cameo in SA doesn't show him too old.

Tai-na doesn't share features with the Larkin, but who knows?

The Highstorms were infused far before Honor & Cultivation arrived. The Listeners' race predate the Shards' arrive and there were Spren too. Honor & Cultivation improved the amount of Investiture in the planet but Roshar was already a functional envirorment designed by Adonalsium

I suggest you to simply put in the Title the [OB] prefix so everyone could see there are possible spoiler in it. In the book there is a reference to a Radiant gaining his Plate at the 4th Oath, but we don't know if this is shared among all the orders. We don't know, there are theory about. Some believe the Plates are made of a bunch of lesser Spren together. Again we don't know, it's possible there is no difference at all. Of course the Radiant could stacks a lot of Stormlight into themself and then let the Plate fuels from that rather from a breakable gemstone. It's also showed the Radiant could summon and de-summon their Plate at will. Lastly (and I believe more important) the Plate could feed of the Stomlight leaked by the Radiant and therefore They could exploit an intrinsic leaking for an useful task. Here it's hard to reply. We could argue the Shards are loosely powerful Spren of sort but probably this would not really figure how much greater the Shards are. We could try to use an analogy. If a Shard is an ocean, a Spren would be mostly a glass of water. Probably I need to make a little digression, the Power of Creation wants to be used and if no one direct it. It will start to develop a Mind of his own. More Investiture uncared you left alone and faster this happen. A Shard is this huge amount of power but usually it's controlled by a mortal mind and therefore this is strictly speaking different from a Spren that is a bunch of Investiture who became sentient....There will be more to say but probably I already started to present stuffs in a messy way. Strictly speaking they can't because their own power is tied to that trait of yours. A Shard will deeply influence his holder (the canon term is Vessel) to align him/her to the Shard's trait (there is not yet a canon name for that but it's mainly defined as intent or mandate). A Vessel could filter the Shard's intent to a degree but it will be mostly in the context of his interpretation of the trait. To say, Tanavast's sense of Honor could be different from another guy's one and therefore if both of them become Honor in different times...They will become two different kind of Honor. They don't but mainly many Shards decide to invest themself into a planet because they wants to fuitfill their intent probably

I will try to answer without going into the Spoiler Side of the Force. Of course the first and more honest answer is "we don't know". Much more, the ones you cited in the answer did not. Some Magic Users did it, but they were not the magic users we have currently in the story...It's speculation what magic they could use. By the way, the place you mention is still there mostly, and there are still people living there. Sure they are few and live in small abitable areas but the place isn't really gone

Just for sake of completeness. As others pointed out, Nightblood's Creation most likely predate Harmony's birth for timeline reasons. But mostly, I find extremely unlikely for the sword to be' made of an Atium Spike. I could do a degree accept an Atium sword or a Spike Sword but not both at the same time. The Atium is priceless, accessing so much to craft a sword is most of anyone could realistic do. Much more that Atium has to be' forged and turned into a Spike (and Hemalurgy's knowledge is not so common) without a real reason. Also find a Sword that is casualty an Hemalurgic Spike is unlikely but at least It is a bit more likely than an Atium's One and could fit with Vasher's inner thought. It could be' a Steel Spike. Maybe the sword they used was a Steel Spike without anyone of them know It...but still is so unlikely.

The Reod doesn't affect the difficult to travel into Sel's CR About how long Hoid was in the city, I remember him making a reference to how long was there...I believe it was years but I can't be sure.
