will the game end?

It would make for a good world event in my opinion, but be lifted at the end of course. I do hope there will be world events such as these, now that I think about it.

Might as well ask what would happen if the Easter Bunny took over Nirn.

Then nirn is pulled completely inside Coldharbor. But that likely won't happen since this is a themepark mmo where the world is kind of persistant.

What happens if Alduin eats the world in Skyrim? What happens if Martin isn't able to stop Mehrunes Dagon in Oblivion? What if Dagoth Ur defeats the Nerevarine?

Time paradox!

Twice Vehk comes and brings CHIM on Molag Bals ass yelling "You are such a terrible husband/wife!!!"

Family drama is worst kind of CHIM

Haha indeed and as a result there would be a final epic battle, fought with mighty spears.

I never figured who played which role in that marriage, Vehk being bipolar and Molag Bal being ... well, evil god
