I think the stone might be the snow on High Hrothgar! O:

In one of the quests in Skyrim, you have to get some Phial and the guy who gives you the quest tells you it was created by infusing it with the magical snow that first fell on High Hrothgar! Can it be that the snow is the stone? I don't know... just calling it 'magical snow' made me think about it

Will the day when the sun would shine, hotter than ever and that fire storms would cover the whole of Tamriel the day when the snow on High Hrothgar melt and leave the tower without a stone? O:

EDIT:
Now that I'm thinking about it.... not really

'The secret Tower within the Tower is the shape of the only name of God, I.'

Eh?

That's CHIM, no? :S

I still havn't finished the Mages College quests yet but could the Eye of Magnus be the Stone of Snow-Throat?

That would just be unfounded speculation on your part. The two are never connected in any way. The only thing the Eye of Magnus is associated with is the staff of Magnus.

Indeed, like I said I havn't finished the questline yet though.

However, I get the feeling that there is more significance to the Eye and the Staff than what I've seen so far, and that the two are not just merely related to eachother.

Perhaps. Definitely finish the storyline first and see where things go. Nothing terribly exciting/innovating, but it's at least something of a wrapup. I won't spoil it, but it may preclude your theory.

Could they be connected via the story told in the Alduagga?

Which one?

I like the idea the Nords are the stone, but I don't see the the Nords being united which restarts the tower at the end of the Imperial Legion/Stormcloak faction quest. Considering they consisted of kill camp x, then y, then z, then the attack of the opposing city without any diplomacy other than a new Jarl being put in place I can only imagine more people getting angrier, and the war getting more gruesome.

The first one. Sorry that I didn't elaborate, I had to leave. Now that I have some time, I shall use it to explain.

My thought was, since the Leaper Demon (who may be Magnus) was in Skyrim at the end of the last Kalpa, and he kinda "died" and was "reborn" as magnus, while standing on a mountain, maybe, in this process, his eye was dislodged and became the stone of Snow-Throat, which is only "half there" because it's a weird time-travelly paradoxical mountain from another Kalpa. It's kinda a hairbrained theory.

The first fight explicitly talks about Dagon being the leaper demon... how could that be Magnus? Or, were you talking about the Greedy Man? That doesn't sound like Magnus to me, but I'll readily admit that Magnus is one of the mythical figures in TES metaphysics I know the least about, and I could be misunderstanding something major.

I can't seem to find the lines, but there are hints that the LDK is Magnus, who was transformed into Dagon. It's something like, "he had lept and torn a hole in the sky." The leaper demons might just be Magna-Ge.

But why would Magnus care for the world so much and hide objects from Alduin if he was one of the Aedra to leave quite early after realizing what he has done?

However, that makes sense that he might be Dagon, or simply a Daedra as he did not exactly participate in creating the world... although he didn't have a realm in Oblivion before he (maybe) became Dagon, no?

Ah, interesting. Thanks for letting me know-- that's pretty nifty.

The meta-plot might extend to Arena.

Perhaps the Staff of Chaos is a Stone? Nothing is said of the specifics of it's creation.

It makes some sense... I mean in Arena it was not a specific province but the whole of Nirn :S
And that might explain why the dragon claws look so similar to the Staff O: Yes? no? maybe so?
Probably not

The Staff of Chaos, rather than being destroyed, was actually put back together, right? That seems to imply that it wasn't a stone, per what I'm arguing the meta-story is. I may be remembering incorrectly, though.

I don't believe we ever learn the final fate of the Staff of Chaos. You reassemble it, then touch it the Stone of Fire, which kills Tharn and opens a portal to Oblivion where the Big E and Warhaft were imprisoned. But what actually happens to the staff is left to conjecture.

I just thought of this, so I'd thought I'd drop a note:

The stone of High Hrothgar is the Dragonstone you fetch for Farengar Secret-Fire at the very beginning of the mainquest. You know, the one you think is significant but you never hear about ever again?

Ha, nice. Whatever does happen to that stone, does it just sit on his desk? I think I may have spoken to him once after that section of the quest was over, the next time being when he stole blood from the captured dragon (I don't think anything significant ever comes of that either).
