All Metalic Arts work anywhere. And both Allomancy and Hemalurgy are directly linked to Harmony. So I think Harmony shouldnt have troubles to reach any Allomancer and Hemalurgic Construct anywhere in Cosmere.

For me Lirin, if he becomes Radiant, should be Stoneward. It matches well with his stubbornes and also with his constant need to help people. And also creates interesting dynamic with his pacifism, because Stonewards were always very militaristic Order. Also, because Radiancy sometimes is family bussines, I think Shalans Brothers should Bond Spren. Obviusly, Balat should be Dustbringer, because this Order is all about controling himself, and Power. This Order would be good for Jushu also. For Wikim, I think he should be Truthwatcher - definitly will be good friend with Renarin.

You dont need to be Rosharan to atract Spren, also you dont need to be Nalthian to aquire Breaths. So you simply can be Scadrian Metalborn who buy some Breaths and go to Roshar and Bond Spren.

I had very similar thoughts some time ago! Probably is not, because imagine person without any identity. It would not know who he/she is, would have basicly total amnesia, I think. The same is why you cant store 100% of Health in goldmind, if you do this, you simply die. Or you cant store 100% strengh, the same reason. This is not magical limitation, but more physical limitation of human body or mind. Yeah, probably with Twinborn you can bypass three powers limitation, because both Twinborn powers would be counting as one power set from Identity perspective. So limiting number would be six powers for 3 Twinborn. And now just wait for Mistborn then... Or maybe Southerners have other technology for transfering invested charge between cubes, and they simply have storages of Allomantic Steel charge, because Allomancers are so rare that is just one per generation or something, and there is no Coinshot between them currently. Or maybe indeed they need something more to give Allomancy. Connection to Harmony maybe?

We also know Harmony is trying to build coalition between Shards and is sending letters to them (and to Hoid). As we are aware, he isnt sending them telepathicaly, or throu Spiritual Realm, so someone needet to carry those letters across Cosmere. And who is better as messenger than creature you can always directly take controll over?

Well, Culti maybe. Odium? Not Raise. Taravangian - yep, he could do something like that.

Point is, Stormfather indeed starts bonding with Gavilar, so he is sending visions. But we think someone, main theory is Ishar, hacks to Connection between Stormfather and Gavilar and is impersonating Stormfather.

It can first influence just few people, is actually very possible that started Influencing people with Honorblades, as they are most dangerous and maybe even have ability to resist, then Stoneshamans, and then rest. This can take few years. Also, why assume Ishar was using his Honorblade? He could use other magic, maybe Fabrial, or even offworld magic.

We had literal words about hero dying before. Even few times. So im still not sure, soul hangs in Cognitive Realm for a while after death.

Yep, this. And if im not mistaken, Stormfather wasnt affected by Jezrien's death. Other heralds, on the other hand, will indeed feel this. The whole aperance of "Stormfather" is awfully similar to what Thaidakar did with the Seon. Also, Stormfather never want to replace Heralds and set new Oathpact. But Jezrien indeed wants do exactly this. Is possible that Stormfather is giving visions, but Ishar is hacking to this Connection. First I thoght that this can be Unmade (more specificly, Dai-Ghonarthis) but indeed, Ishar seems to be better candidate.

Probably not. Metalmind is spiritualy part of Feruchemist, part of his Cognitive Self. And object can be fully inside the bubble or fully out. So metalmind can be with Feruchemist inside, or can be outside but he would not be able to touch it and Fill it - because Bubble Border would be constantly between them. Still dont understand why dont simply use Bendaloy Bubble instead...

Nope. Cadmium bubble is physically slowing time on the area, not just relativly for user, @Skaromas is right. Even if metalmind spiritually will be normal, feruchemist's storing speed depends on his reaction time, and his own perception, so slower time for him - slower storing. If you want to speed storing up, you need to use Bendaloy/Cerrobent, witch has reversed effect.

Fortune is not Shard. Is more like function in Spiritual Realm.

Maybe sunlight has also very powerfull radiation? Maybe even supernatural one? Like will kill not resistent life even hundreds meters underground. So is not just going underground, you also need shielding technology. This is actually easy. Form sort of Furnace on the ground, fill it with all stuff needet, and wait for day. Go around planet and just collect metal - sun is doing all job for you.

Maybe there are underground plants and their roots and stalks are good for wood. Or in polar regions of planet are forests with half the year vegetation time (and are burned by sulight in other half, like eucaliptus trees in Australia). Of course, they also need to grow very fast.

Gravitation is for flying, not Adhesion. And Dalinar doesnt have it.

Yeah, but is many times implied that Auxiliary is killed (is very talkative, for the dead) because Sigzil break his Oaths - what is awfully Radiant-like. Maybe indeed Sigzil changes Order to Elsecallers, or maybe his Spren was heavily changed by Dawnshard.

Human Radiants, yes. We dont know how Singers would behave, since they are closer to Cognitive Realm and more sensitive for Investiture.

She probably just overwrite them with her Radiant powers, afterall Radiants eyes changes as well.

Red eyes actually dont mean just any Corrupted Investiture. They are sign of Corrupted Innate Investiture. Sign of posession: - Thunderclasts have red eyes because they are unnatural posession of stone/crem. In spren form they are black. - Soldiers influenced by Thrill have red eyes. - Fused have red eyes - they posess not originally their bodies - The same with Trells Immortals - Regals have their bodies not-naturaly for them changed due to not fully natural bonding with Voidspren. - There are also Shades, but not sure about them. Maybe their rage (Hatred?) also is not their natural state, but they are influenced by power who Splintered Ambition. And hence they ARE their own Investiture, they are Corrupted.

Aluminum is not cheap just in US. And on Scadrial they can also have Hydroelectric Dams (In New Seran maybe?). Dont even mentioned potential limitless electicity with Iron Feruchemy.

Im with @teknopathetic Nightmares are very similar to Shades - is heavily implied that they are made from people during "rain of God's blood". They are not the same, but are very similar as they are also Cognitive Shadows created via corruption of innate Investiture. Also, like Shades, Nightmares are Pulled to the human minds (Shades are pulled by certain actions, but they also target human minds when provoked).

Probably, even is once mentioned that "daystar" is right above horizon, just like Venus is.

We know Ambition fled from Threnody to unspecified location and was killed there. Why this cant be Lumar?

Text highly sugests that reciver of story knows only his planet. And all Vessels except Sazed knows their Planet AND Yolen. So this rules out all Vessels. Rules out also Heralds, because they are from Ashyn and travel to Roshar.
