I am not a huge lore buff when it comes to TES, although I was wondering, since there was a Dwemer in MW and ESO is roughly 800 years before that point will there be Dwemer in the game? I'm not sure at what point in the history the Dwemer went extinct, just curious.

Im not a great lore buff, but from what I understand the entirety of the dwemer race has left the realm, due to something in the lore of MW. This is all fuzzy as I read it a while ago, but I really think it would be very unlikely.

The battle of red mountain was at the end of the first era. Unfortunately they are already gone.

They went away over a thousand years before the events of TESO... The First Era is crazy long due to the dragon break.

And that Dwemer from Morrowind survived by fluke; he was in the outer realms at the time of his people's disappearance.
