Stormgate knows that... He said that the Sword that later Vasher (or better his wife) awakened to create Nightblood was used to kill Adonalsium.

It is stated that Nightblood doesn't destroy investiture, it simply The investiture Consumed and Leaked by it isn't in a form avaliable. But Nightblood don't destroy it

I'm working on a Story with a similar World, but I stuck myself with the sociological issues of that kind of setting

I think Nightblood can't change appearance, It seems uncapable to have both his power and mind at the same time. Changing appearance it's something more it have to do. And if Nightblood may change, why Did Vasher not try to hide it when He was on Nalthis ? Nightblood was easy to spot and reconize also if Vasher was to use a stealth method.

First of all if you want match Shards and Metals you have to put also Hemalurgy Effect in the effort. Second you have to estrapolate some "core" about how a metal works in the Metallic Arts. Just at the end you my try to mach this "core effect" with the Shard. I am not sure if this may be possible but without doing this, you will only creates couples without any much sense (when for example you may use Allomantic Pewter to Surgebinding and Durallumin Feruchemy for Awakening) and anyway, how you may decide about magic system made by more shard or you don't know in depth ? (For example Surgebinder) Or you use only the "pure" manifestation of Investiture arose by a Single Shard ?

Also Denth may suppress his Divine Breath (and probably Astrael did the same)... Without counting that without Divine Breath Vasher would die in the second itself he try to store somewhere.

Just a thing, because I read it yesterday: From this WoB now we know that Voidbinding isn't see yet... Therefore the Listener's Form of Power are not Voidbinding .... This changes a lot of things.

He probably just swapped the names (or He is just an Orhodox Vorin ) Anyway one of the more problably explaination about the being knowed as Stormfather sees it as a merging between a Tanavast's Ghost (Cognitive Shadow) and the Rider of the Storm (Spren)

Probably (but I am not sure) they aren't big enough, or something like that... If a Beast large as a Charmfiend (and a big one) has a Gemheart of Human's Head size... something more smaller may have just a little (like the salt) or none cristal in them.

This three planets are the only ones in Great Roshar with life, but there are other planets in that System

I am not sure about, once I read a WoB about "Feruchemist who may store Stormlight in his metalmind" of course at the time we know very little about Nicrosil, but seems you may be able to store any kind of Investiture in Nicrosilmind...Of course this it's mean that is simple to do that.... but probably Nicrosil works like Tin, you choose what put in the metalmind with the extra difficoult to know well your own Investiture.

For now I think the "Kelsier's return" is only a fact of Connections.... He manages to re-Connect itself to the Physical Realm (And I think that the Spike he has, it is exactly an Connection Spike (probably another Human Attribute)).... Of course we can't know if He has his previous ability (as Mistborn), but through the Bands he manage to became an artificial Fullborn....therefore I think he is no more an Allomancer of his own.

If I remember right, every GreatShell (chull included) have GemHearts. But the GemHeart's size is function of the Greatshell's size and therefore a Chull's GemHeart is something really little and without any great value (compared with the useful beast you need to kill).

I remember a WoB that ask exactly if the "Medallion works alone with the Blanck Identity trick and how you may tap Nicrosil without being a Soulbearer". The answer was something like "the Creators of the Medallions know some other tricks" therefore probably we have some missing information.

Voidus if I remember right the Cognitive Human's Attributes Stealable through Hemalurgy are already on the books and there is no "memories", therefore you problably can't steal memories.

See through the Spiritual is hard and there everything past, present and future are the same, probably they recive everytime something random and this is the reason to the great number of Death Rattles... The Unmade keeps trying until it get what it want ? Or at least I think it is the reason, also a full Shard have trouble to see something specific in the Spiritual, a lesser being have more trouble to navigate the Eternity.

And of course He Had a horse named Bela

If I am not wrong this thing was discussed also in another post. And I am pretty sure that the voidbinding also use the surge in some way. But there is a little problem about what you wrote. In all the traditional folklore of the Voidbringer, they are always associated with red eyes. It's a so famous trait of them, that also the KR with the red eyes was a little associated with them. Therefore I find unlikely that all the Listener during the Desolations was in Stormform alone.... Maybe the Listener in every form have always red eyes. This may be for some reason like "The Voidbinding has 9 forms everyone of them gifts a specific twisted Surge and they all have a single twisted Surge in common" or some other reasons...

The Stormfather is quite a "special case" because it's he the merging of Tanavast's Shadow with a powerfull (I suppose) Spren, the Rider of the Storm. Now that we saw in SH how the Cognitive's Shadow work... We may try to explain better what happened at Honor's Death

Well a possible explaination may be: the Unmade (in the Cognitive) reachs someone near to Death (requirement to Interact with it maybe) and use the victim's Investiture to push itself a bit in the Spiritual Realm (to catch the future)... while the victim are drained by his own Investiture shares the vision from the Unmade. (Something similar to what Leras does with Kelsier...but Leras has no need to feed of other Invetiture). Another possible explaination is similar to the previous but the Unmade needs a "Victim" because the Humans has anchor to all three realms and It may use this propriety to push the victim in the Spiritual and "share/steal" his vision of the future.

Of course Adonalsium was a pig and every World has some pigs like effigies of the maker... also the worlds created by Shards have pigs because they are modulator to the power of creation, without Pigs the Investiture can't reach the Shardworld's focus properly....

Oudeis I like your interpretation, but it's possible that the people in that country develops the "right phonetics" through their growing Connection to this land.

I catch the earring as Spike as soon as we discover how the hemalurgt works (I can't remember if during the "Survivor of Flame"'s born or when we see how Koloss are created. But I didn't understand that se got extra Bronze power from it...And only later I understand the deep implication of it. But a Friend of mine while he was reading HoA text me something like: "NOooooooooooooooooo The Earring, you ****** to have to say to me!"....Therefore many people was really surprised by the revelation during the final sequences.

Probably yes but it isn't hard to obtain some Atium

Yes you may burn your Spike, but "it hurts like hell"
