That makes little sense to me, given that the whole Tonal method was built around the Heart. Who was going to be in the Mantella, then? The Mantella is cheap substitute for the soul of a god. And Numidium didn't need to walk around and destroy cities, it was bound for bigger things.

No, far too many misinterpretations to be a viable source, not to mention it is a wiki. Stick with primary sources, which are more easily and easily found on The Imperial Library.

Awesome a Morrowind question! Did they teleport to another relm of existance? Are they all dead? I think they moved in with keibler elves to make cookies

Some one already posted a link to "Final Report to Trebonius", but here is the short version: The Dwemer like all elves believe that their gods became mortal and had to give birth to children to last. In essence the sacred became the profane. They found a way to reverse that and in doing so they became the golden skin of the Numidium, the Brass God. Except for a minor hickup, that they never ascended. It's speculated that Yagrum had to throw the on switch.

I have no idea how the dwemer wanted to construct the Mantella. But I wouldn't call Mantella a cheap substitute for the soul of a god, Mantella is the Crux of Transcendence, now I don't know what that means, but it sounds important.

Is there any particular reason the Mantella can't refer to the Heart being fastened to the walker?

Apotheosis.

Yeah, because the dwarves failed. Had they rigged the Mantella to use the tones from the Heart, upon contact with the tools, the Brass God and Dwemereth would have walked, not their Doom-Wraith.

Kagrenac wouldn't let his people suffer for apotheosis. The highest act of love - creation or apotheosis - requires suffering, right? Parenthood was a profanity they refused to continue in.

I don't follow. What Doom-Wraith?

I don't know exactly what you're getting at, but some things seem backwards here.

I don't know where you're getting the idea that Kagrenac wouldn't let his people suffer. The passage that comes to mind is "sacrifice so many," something-or-other, "create the golden skin..." I forget the exact words.

Apotheosis can be an aggressive act; it doesn't make me think of the Loveletter ordinarily.

And what's that about parenthood? I would associate parenthood with subcreation and the normal movement from divine to profane. How was that in the cards anyways? And what does this have to do with the Heart versus a different receptacle.

The dwarves didn't enjoy being parents of perpetually weaker spirits, did they? So what did Kagrenac's Architects want to do about that? They uncovered the Heart and made a Mantella. They theorized a way to erase all the levels of creation, without sacrificing themselves to produce the divine self they wanted.

They would use Lorkhan's Heart and the tools to re-create the moment of creation his heart was removed. Except their plan failed. Kagrenac didn't incorporate the Mantella, and the Dwemer were simply absorbed. Sacrificing their souls was not the intent, that would be grand theatre. Numidium was an interface, or a shield meant to be reused.

The Dwemer did not know love. They did not want to suffer to create their god. Again, hence the elaborate plan with the tools and Lorkhan's heart, to fill the Mantella with that stone's creatia. Whereas Talos knew love. He sacrificed himself, Zurin, to fill the Mantella. The Dwemer were absorbed into a Tower with no possipoint.

I guess it could be possible, The Arcturian Heresy is not clear on this matter, in one paragraph it says:
"He discovers the reason the Numidium was made and some of it's potential. Most importantly, he learns the Underking's place in the War. But Zurin Arctus was working from incomplete plans. He thinks it is the heart of Lorkhan's body that is needed to power the Numidium."
While in another:
"The Numidium, while not the god Tiber Septim and the Dwemer hoped for (the Underking was not exactly Lorkhan, after all), it does the job."

A small band of Dwemer returning from a some millenia trip from an Outer Realm and settling down in a Dwemer ruin would be interesting, i bet that many would love to see some living ones.

Where is the Numidium??

Still invading Alinor, or blown to hell in the Illiac Bay. Then again, it says "[censored] you time, I'm a paradox!" and proceeds to kick Akatosh in the balls repeatedly, in addition to shooting him the bird while smoking, because we smoke when we shoot the bird!

Numidium's the Zybourne Clock. Only there are eight Numidia, not five.

One thing I have to say is that I found this text from Skyrim intriguing:

"This scholar would like to suggest, however, that many structures west of Morrowind were built after 1E420. When the Clan Rourken left Vvardenfell, it seems evident that several clans broke off to create their own settlements, and chose to live in greater isolation than their Eastern brethren. This theory is particularly fascinating, because it leads me to believe that Dwarven architects may have developed even more elaborate methods of hiding their strongholds over time.

This opens the distinct possibility that undisturbed dwarven archaeological sites exist throughout Tamriel, even in southern areas like Cyrodiil or Black Marsh where Dwarves are not believed to have ever had a significant presence. Though we ought not get carried away on flights of fancy, one could extrapolate this logic to suggest that some Dwarven Clans were living among us for much longer than previously believed, perhaps well beyond the disappearance during the War of the Red Mountain in 1E700."--Dwemer Inquiries Vol I

So we have a few things we can draw from this. One is the possibility of there being Dwemer ruins all over Tamriel, ruins that are exceptionally well hidden, ruins built by Dwemer that broke off due to disagreement with the clans of Morrowind.

Now we have two main basis for our belief that all the Dwemer are gone. One is Yagrum's testimony that he searched high and low and couldn't find anybody, the other is Vivec's, who says he can't sense them anywhere. I think a decent question is whether these clans who went through all this trouble to isolate and make themselves hidden, being the genius Dwemer folk that they were, could have found ways to hide themselves even from the prying consciousness of a god (as for Yagrum, him being of the Morrowind clan he would have no knowledge of the whereabouts of these other clans and so it's only natural that he wouldn't have found them).

This has no real basis but it was my first thought upon reading that book. There is also the matter of the disappearance itself to deal with considering how it affect Dwemer as far away as Hammefell, so not only would one have to presume they devised ways of counteracting Vivec's scrying but also the effects of Kagrenac's tampering on the Heart (which if the Dunmer texts are trustworthy imply that not even the Dwemer king himself knew about Kagrenac's work, making it unlikely that some Dwemer hiding out in ruins beneath Cyrodiil would know enough about it to have tried to counteract it).

Anyway, yea, that...

I liked seeing wizards try reverse engineering their tech. I'm hopeful for some radical changes in tech, augmenting magic.

Is there a way to reverse the process that absorbed the Dwemer in the first place?

No

I was reading some books in game about the Dwemer. To my understanding their Architectural styling was a cultural/spiritual decision. Which was based apon the time/place and architect.
