Vivec just accepted the fact that the Dunmer would no longer worship him, instead going back to the Three "Good" Daedra.

He most-likely died in the final cataclysmic impact of Baar Dau, seeing as he couldn't hold it up anymore due to the total loss of his divine power. Sure, there was the Ingenium holding it up after he lost his power, but... that didn't end well.
