People really need to quit inventing 'theories' about what happened to the Dwemer.
We were told what happened to them over a decade ago.
They became Numidium, Numidium blew up.
They are not coming back.
In response to you; I do know that happened to the Dwemer, about them forming the "Bronze Skin of Numidium" and I get it. Although, even so, there are still Theories as to why Yagrum Bagarn didn't go aswell (
which could be due to him being in a different plain of Oblivion, or not), and why Numidium/Anumidium didn't start up (
still, maybe due to Yagrum not being part of the skin, who knows?).
But my point still stands. No one knows
Exactly what happened. Even what we know thus far is only a Theory.
I was only flinging Ideas out by the way. I never said my idea is set in stone or anything. My guess is as good as any others.
