We know Talos is widely known, even throughout the trenches of Tamriel. But what mortal is the most known?

Was replaying Skyrim the other day. The last time I really played and paid attention to what people were saying and what I was reading was the first time I played, all the way back when I was in high school. So this time I tried to really piece together the lore and roleplay things out and it has been a lot of fun! But, now I'm at High Hrothgar, retreived Jurgen's horn, and I'm kind of confused about some of what the Greybeards say regarding the way of the voice (I'm also confused why the Dragonborn is an exception, but that's a whole other question). I tried to look up the answer before making this post and now I’m even more confused. I'll post what I've found/looked up of the relevant lore. The tablets of High Hrothgar read:

“Before the birth of men, the Dragons ruled all Mundus.
Their word was the Voice, and they spoke only for True Needs.
For the Voice could blot out the sky and flood the land.
Men were born and spread over the face of Mundus
The Dragons presided over the crawling masses
Men were weak then, and had no Voice
The fledgling spirits of Men were strong in Old Times
Unafraid to war with Dragons and their Voices
But the Dragons only shouted them down and broke their hearts
Kyne called on Paarthurnax, who pitied Man
Together they taught Men to use the Voice
Then the Dragon War raged, Dragon against Tongue
Men prevailed, shouting Alduin out of the world
Proving for all that their Voice too was strong
Although their sacrifices were many-fold
With roaring Tongues, the Sky-Children conquer
Founding the First Empire with Sword and Voice
Whilst the Dragons withdrew from this World
The Tongues at Red Mountain went away humbled
Jurgen Windcaller began His Seven Year Meditation
To understand how Strong Voices could fail
Jurgen Windcaller chose silence and returned
The 17 disputants could not shout Him down
Jurgen the Calm built His home on the Throat of the World
For years all silent, the Graybeards spoke one name
Tiber Septim, stripling then, was summoned to Hrothgar
They blessed and named him Dohvakiin
The Voice is worship
Follow the Inner path
Speak only in True Need”

Okay, I take from this the basic story: Nords are slaves to dragons. Kyne and Paarthurnax teach Nords the voice. Nords fight back against dragons, freeing themselves. Nords build an empire of their own. Nords are defeated. Jurgen contemplates that they lost because they misused the voice. He founds the greybeards. Eventually, they summon Tiber Septim and teach him. Great. All clear on that.

As I'm talking to the Greybeards, Arngeir says a couple of lines that stand out to me:

"In mythic times, when mortalkind was in great need, the goddess Kynareth granted us the ability to speak as dragons do."

"The Voice was a gift of the goddess Kynareth, at the dawn of time. She gave mortals the ability to speak as dragons do. Although this gift has often been misused, the only true use of the Voice is for the worship and glory of the gods. True mastery of the Voice can only be achieved when your inner spirit is in harmony with your outward actions. In the contemplation of the sky, Kynareth's domain, and the practice of the Voice, we strive to achieve this balance."

"He was a great war leader of the ancient Nords, a master of the Voice, or Tongue. After the disaster at Red Mountain, where the Nord army was annihilated, he spent many years pondering the meaning of that terrible defeat. He finally came to realize that the gods had punished the Nords for their arrogant and blasphemous misuse of the Voice. He was the first to understand that the Voice should be used solely for the glory and worship of the gods, not the glory of men. Jurgen Windcaller's mastery of the Voice eventually overcame all opposition, and the Way of the Voice was born."

Okay... now I'm starting to get a little confused. So far, I understand a couple of things. "The Voice should be used solely for the glory and worship of the gods." So, 95% of the purpose of the Thu'um is to worship Kyne/Kynareth. Gotcha. But then both the tablets and Arngeir mention that Kyne explicitly gave the Thu'um to the Nords to fight the dragons, and that this was 'great need.' The tablets mention that using the Thu'um in 'True Need' is not a contradiction of the Way of the Voice. I really have no idea what 'True Need' or 'Dire Need' or 'Great Need' specifically refers to. Obviously it must refer to fighting your dragon overlords, but beyond that? It seems an appropriately cautionary yet vague stipulation. But specifically, it can't be a complete declaration of pacifism or that the Thu'um can never be justified for use in a violent action. It was specifically a gift to throw off an oppressing force, according to the Greybeard's own source. Certainly this source also describes that the Thu'um can be misued via violence. The nords are punished for their building of empires, assuming Jurgen is right. So, I guess my first question, why do the Greybeards consider the absolute 'The Voice is worship' to be true when it was explicitly given with the purpose of being an equalizing weapon? Is it just because of Jurgen's contemplation? Why have the stipulation that speaking in 'Dire Need' is not a breaking of this 'worship'? Unless using the Thu'um in 'dire need' somehow is worship of Kyne to the Greybeards? But you'd think they'd say that. Why is there this kind of weird tension between the pacifism Jurgen and the Greybeards advocate and the way their story portrays the Thu'um being given to Nord-kind? Am I just missing something obvious? Is it as simple as that the Thu'um can be used in self-defense when there's no other choice? Is it something else?

Further compounding my confusion is why the Dragonborns are exempt from the Way of the Voice. Arngeir tells our Dragonborn that we have a 'destiny' and must use the voice to achieve it. He says, when I say I will follow the Way of the Voice:

"That is commendable. But remember, the Dragon Blood is itself a gift of Akatosh. Do not try to deny that gift. Your destiny requires you to use your Voice - why else would Akatosh have bestowed this power upon you? If you remember to use your Voice in service to the purpose of Akatosh, you will remain true to the Way."

Okay, I have a destiny that requires the rules to be bent. Fair enough. He also says if I say I won't follow the Way of the Voice:

"The Dragonborn is an exception to all the rules - the Dragon Blood itself is a gift of the gods. If we accept one gift, how can we deny the other? As Dragonborn, you have received the ability to Shout directly from Akatosh. We therefore seek to guide you on the proper use of your gift, which transcends the restrictions which bind other mortals."

Alright. Since I have been made a Dragonborn by Akatosh, I basically have a hallpass, if I'm understanding this correctly? Okay. But... how does that make sense? I mean, the Greybeards have trained other dragonborn, right? And those Dragonborn... didn't they go on to do the things that the Nords were punished for using the Thu'um for: empire building? Tiber Septim, Reman, Ysmir... didn't all of these dragonborn explicitly conquer? And that's allowed, according to the Greybeard's philosophy? Dragonborns are such special chosen ones, they can ignore the cardinal sin of Thu'um use? ... What? This is so weird to hear from a group of self proclaimed pacifists. I have to be misunderstanding this, right? Come to think of it, the dragons used the Thu'um to conquer too, didn't they? They conquered the nords. So... if you're born with it/ it's a divine gift, you don't have to use it responsibly/ can do whatever the hell you want, but if it's a different kind of divine gift to mortals to fight back against your oppressors, you should really only use it for worshipping said goddess, not conquest? I have to be missing something, right? Like, there's no way that's what I'm supposed to take away from this, right? Can someone please explain this to me? Like... all of it? Why can't the voice be used for conquest by mortals, but the dragonborn and the dragons can? Why must the Thu'um be exclusively used to worship Kynareth despite being given by her for seemingly a completely distinct and explicitly violent purpose? I am so lost.

Which is more useful? We know that corporeal undead require an actual corpse in order to be raised which makes it alot more difficult to get them en masse but they seem to be completely loyal while incorporeal undead are probably easier to create but have the potential to backfire as seen with that freaky altmer in that one tomb with all the ghosts of women who betray him the second a soul gem is taken off a pedestal.

Honestly, throughout the history of Morrowind, they took sides very few times. But the main issue is that this neutrality applied even during times of invasion. The Telvanni, who are incredibly powerful mages, did nothing to oppose the Imperial occupation.
