From what I read of Vivec's sermons, it seems that Vivec was a god seemingly all his life as he was forced to marry Molag Bol and fight his offspring in epic battles. Yes, I know this is biased towards the tribunal and when they achieved apotheosis, as it is pretty much directly challenged by the Trial of Vivec.

From what I know, he was only a god after the Tribunal supposedly murdered the Hortator and used the tools of Kagrenac and Lorkan's Heart. BUT, if this is the case, then how did he defeat all of his weird offspring (city-face, etc) without being a god at that time prior to him being a counselor to Nerevar? I knew it was biased but this is confusing me greatly.

There are two V'veks: one was a mortal, and the other had always been. Their histories married in Red Mountain, and the V'vek of the present was born.

So the one that has always been defeats the linearity of time I assume? It's hard to wrap my head around because I keep trying to think he went back in time to do that haha. I must research more.

Yeah time is pretty flexible in TES Lore. I could be wrong, but I think I heard that there was a Dragon Break when they used the heart, making them always being gods and "being mortals and then turning into gods" at the same time.

Yes.

Apotheosis gave mortal V'vek the sensation of whens and wheres he'd never been, but the immortal V'vek had and experienced them in dreams. Was mortal V'vek only a dream?

I completely forgot about that Dragon Break, thank you. Everytime I hear Dragon Break I just think of how awesome it would be to see like 6 Numidiums fighting across Tamriel.

"At this the egg laughed. 'I am given too much to bear so young. I must have been born before.'"

And then me birthing my mother and father. :celebration: ... Oh i almost forgot that i'm male... [NUMINIT] :banghead:

The things which Dunmer made and saw during one of Dragonbreaks might be interesting to witness. Tribune and Good Daedra and Bad Daera all making effort to protect Morrowind from effects of it. It was when Auriel was broken by Selectives, if i recall correctly. Which makes me wonder their reasons.

Well doesn't the same thing apply here as with Vehk? The Aedra were split into that two universe concept, and were dipping into protonymics to kinda get rid of any remaining elven features. I've been a lore junkie for sometime, but Elder Scrolls is the only series I always second guess myself, and the bad thing is that it was designed that way haha.

And? Once you're in that sort of position, that shouldn't be hard to find a way around if you know what you're doing.

I ment to ask why Tribune and Good&Bad Daedra protected themselves as well as Dunmer people from that particular Dragon Break? Somehow i've understood that they took Dunmer into different (mental?) place for that ~1000 years lasting Dragon Break, when childs were birthing their own parents and fighting against ghosts... Maybe that is why they are so unique with their religion as Selectives weren't able to touch it and force it to their own mold?

Is there any consensus on where/what vivec is in the fourth era? Would he not have remained a god without the power of lorkhan; shouldn't he have 'mantled' as talos did? Is it possible he actually became mephala, his anticipation?

A popular theory is that he achieved CHIM.

It's more likely that Mephala, from time to time, will assume his voice or appearance while appearing to Dunmer, to trick them into more easily worshiping her, as she does with the Dark Brotherhood through the Night Mother.
