I hope you're right, but I have the feeling that few really expected the moon to fall, and that the cataclysm was sudden.
Not a chance. Whilst the Moon
Baar Dau had kept its impetus and probably impacted High Fane within a split-second, I still don't think (even when ignoring the condensed Morrowind we experience in the game and thinking of a larger scale for everything) the shockwave reached to Tel Fyr. Perhaps some portions of Azura's Coast, but I think Divayth's tower was a bit too far north. That leaves the eruption of Red Mountain, of course, but I think that would have taken slightly longer to obliterate everything. You make a good point that in the time it took Divayth to rally his daughters and Yagrum (possibly others as well like Vistha-Kai), it may have been too late. But certainly, Fyr has demonstrated strong metaphysical understanding through his transmissions with Sotha Sil and the Elder Council in the Obscure Texts. I'm sure he had a plan, regardless.
Divayth may be old and easily lost in his work, but his mind seems to be just as nimble and resourceful as he was in his youth. The next question, of course, is if Mistress Therana managed to get away, and if so, by what convoluted means.
What I mean is, unless Gary Noonan reprises his role, Fyr's dead along his http://www.imperial-library.info/obscure_text/sotha_sil.shtml. It's a good time to retire characters.
Yagrum Bagarn always sounded like the Keebler Elf with a sinus infection to me. :shrug:
I suppose you're talking about his appearance though, assuming Noonan did not only the Dwemer ruins but the Dwarf himself. Surely they could just have him and Divayth cameo by means of a written letter or something if particularly insecure about doing his appearance justice in a future game?
