Well, in the end, it would have crashed anyway. Vivec was becoming weaker, and weaker, and eventually he probably couldn't maintain the rock and the ghostgate for too long. Sadly, it was inevitable, as people lost their love for Vivec (which also meant love in general apparently), and it came down crashing. The fight with Sul and that other guy caused it, because they rejected love. Now, it's time to start anew and try to rebuild. If what MK said in the other thread about the nords of Solstheim is true, it'll be an interesting rebuilding of nordish and dunmer bonds.
And hey, it sometimes does take a huge loss to gain something greater. There's a silver lining in this somewhere; it just won't be immediate.
Interesting, I hadn't thought about them rejecting love as they fought (although really, Sul didn't. Vuhon rejected love in his clingy jealousy of Sul over Sul's wife, though) and I would love to see a Dunmer-Nordic culture. Not the wierd Daedric quest from Oblivion kind, I mean several generations of mostly peaceful coexistence kind.
i havent read the book, but arent the an-zileel totally anti-anything-not-from-argonia? it wouldnt make much sense for a completely nationalistic faction to make their new capital the capital of everything they despise.
Apparently, not a lot of Argonians stayed in Morrowind in general. They were perfectly happy with burning the Dunmer out and going back to party with the Hist. After all, the swamps are their homeland and the Bitter Coast got nuked.
