Ishar is... trying to give himself a true Physical Body instead of a Herald's body or something along those lines then?

I think Nightblood is just an attempt at replicating Shardblades after the Five Scholars visited Roshar and other WoBs suggest the same The knowledge on how to create something like Nightblood coming from the Nightwatcher is certainly an interesting idea but as Cultivation herself confirmed, the future is not set. I don't think a Bane like getting killed by your creation is quite possible. It's not impossible, Preservation and Cultivation both show how powerful futuresight can be, but it's not destiny manipulation. And I don't think they give Banes like that, it's mostly Spiritweb manipulation. It's not impossible that the knowledge came from there though, maybe Cultivation wanted a faulty but obscenely powerful Shardblade adjacent like Nightblood to kill Odium, but that part of the machination could just as well have been something after Nightblood passed through to Roshar (and passed into the Nightwatcher's hands in exchange for knowledge on how a Returned could feed on Stormlight or some other deal) or Fortune to predict that the Returned would return to Roshar for its free Investiture, likely bringing Nightblood along, which would otherwise feed on souls back home. All are interesting. Also, note that Brandon mentions that Warbreaker was written to give a backstory to characters in Stormlight, so it's not impossible that Cultivation was involved in Nightblood's creation.

We also have this:

And you've got it!

I think the current theory is that the Perpendicularity is on the sun. That... that would make travel difficult, yes. Of the unpublished works, the Aether world had two Perpendicularities but the rewritten version might do away with that and have no Shards present at all, and make the Investiture system pre-Shattering. Maybe some of the Aethers would still grant Transportation style powers. Yolen has knowledge of atoms, who knows where they might be scientifically now. Investiture and anti-Investiture knowledge on Roshar might help. Hell, war advances technology in Earth, the arms race on Roshar might very well do the same on Roshar and revolutionize everything. Investiture and anti-Investiture as fuel maybe? (yeah, I watched a lot of shows where spaceships used anti matter fuels, it's not actually viable afaik) Ashynite magic might be useful here. And the Silence Divine is supposed to be set in the latter half of the Stormlight Archives. Whatever magic keeps those upside down floating cities working might be very interesting to an enterprising Roshar. The idea of Spiritual CRISPR is very interesting. That would certainly make magics that directly interact with Spiritwebs very important: Forgery, Hemalurgy, Spiritual Feruchemy quadrant, Spiritual manifestations of the Surges, possibly AonDor can program something to that effect, possibly Dakhor (side-eyes using death as fuel to breach the Realms: Moelach does it to access futuresight, Dakhor uses it to teleport, Threnodite macabre spontaneous Perpendicularities might be of a similar nature), the Old Magic... Lift's Boon of turning food to Lifelight could be invaluable!

Shadesmar is faster than light only when crossing between planets, as the empty space without any minds tends to get crunched. So you can traverse vast interstellar spaces in a few footsteps but a neighborhood would be roughly the same size. The Oathgate spren seem to be Inkspren and Reachers in appearance but made gigantic, which makes sense since they're the ones that grant the Surge of Transportation. We know from RoW that the Parent that they were referring to was the Sibling, so presumably the Sibling altered them to create the Oathgates, which also makes sense because of the ten central Oathgates of Urithiru. The White Sand lichen, I'm not sure using those as batteries would be efficient. They seem very low-Investiture. Remember in OB, the screamer Voidspren could detect Kaladin's use of Gravitation but not Shallan's Lightweaving and how on Shadesmar they saw that Shallan's Lightweaving (and the strange making beads imitate things in the Physical, which seems like a manifestation of the Surge of Transformation that isn't Soulcasting) were more economical uses of Stormlight. And then we see Hoid's White Sand getting charged by Shallan using Lightweaving near him. Yeah, they're a bit too low capacity, I think. Wonder how Khrissala got off-world. Darkside magic is supposed to be more on the down-low but assuming the Darkside emperor's Violet Skycolours opened up something new, stuff might be possible there. I wonder how this stuff might be usable on Threnody. Is their original Invested Art (assuming they had one) still accessible? Ambition seemingly did not leave behind a Perpendicularity and is now located elsewhere, but the Investiture from "the Evil" might be usable, if it's a Splinter and not like Fainlife (which it could be because the Vessel of Ambition, Uli Da was a Sho Del, Fainlife). Or perhaps we should be looking at the temporary macabre Perpendicularities, which are likely to be a gathering of Shades, as Khriss seems to imply in the AU; and we know from Mistborn era 2 broadsheets, courtesy of Nikki Savage, that Nazh has a gun that uses Shades somehow! So Shade tech might be a go! First of the Sun already has a Perpendicularity on Patji, if a bit inconvenient. The other planets in the system probably don't, Khriss didn't mention them beyond giving a single comment on their life, but given the peculiar nature of having a Perpendicularity without a Shard present that she commented on for First of the Sun, she would've mentioned any other Perpendicularities. On Sel, Devotion's Perpendicularity still exists, and it is near Elantris, which I imagine will become a hub in the future. Dominion's Perpendicularity also presumably still exists. Scadrial era 2 seems to have a Perpendicularity on the southern mountains of the Elendel Basin, as per the Broadsheets, and South Scadrial already has airships and is using their godmetal. Some people have theorized that the original Well and Pits might also reform. Roshar is starting on airships already, and Raysium sounds like a very interesting godmetal as it's an Investiture conductor, oh boy, that opens up magi tech nicely! That leaves Nalthis, they also have a Perpendicularity and many people in-world seem capable of discovering and using it, and it already has officials.

Vasher uses a few colourful Nalthian expressions, is a Cosmere lore expert, general disposition and mannerisms also matched Vasher, so people correctly guessed his identity and got confirmations from Brandon, and of course with RoW, we hear his view on being Returned, are directly told by him that he isn't from Roshar and see him using Awakening. Vivenna gives a few hints about her past, her blade raised some eyebrows, used Awakening and finally she had the Royal Locks, so people once again correctly deduced her identity and got confirmation from Brandon.

good guesses but no, neither of them are the correct answer 1) This character has come close to death many times and in many ways 2) This character has interacted with a Shard 3) This character was manipulated in some capacity by someone with not mundane means 4) This character is noted to have a sad voice 5) This character was impersonated by an important character

Scale

Nope, good guesses though! 1) This character has come close to death many times and in many ways 2) This character has interacted with a Shard 3) This character was manipulated in some capacity by someone with not mundane means 4) This character is noted to have a sad voice

Oh, oops, sorry Navani referred to it as science and I think that fits: interpreting Cultivation as nature or progress or growth and Honor as structure.

Psst! They're talking about Odium and Cultivation's hybrid Light, not Honor and Cultivation's hybrid Light

Nope! 1) This character has come close to death many times and in many ways 2) This character has interacted with a Shard 3) This character was manipulated in some capacity by someone with not mundane means

Very good guesses! But nope! 1) This character has come close to death many times and in many ways 2) This character has interacted with a Shard

Freedom seems the most likely, it fits very well narratively and with the characters in question. I think it can also be associated with defiance

1) This character has come close to death many times and in many ways

Blushweaver?

These might be useful: The speculation presented in the above thread was confirmed here: There's also this: I don't believe we have more on this Lutha individual at present

Culti- Thai- Resta- Hmm... RoW has given us quite a few names Oh wait, did we ever get Lightsong's real name?... I think we did Obligatory Hoid guess? Nah, what are the chances Vasher? Assuming any of these: Vasher, Kalad the Usurper, Strifelover, Peacegiver the Blessed, Talaxin, Zahel, or Warbreaker the Peaceful aren't his real name
