As far as I know there's no concrete canon answer for this, but I'm curious to hear some speculation. We know that at some point prior to the events of Morrowind (3E 427) Yagrum Bagarn is in Vvardenfell, contracts corprus, and comes into the care of Divayth Fyr.
If I recall correctly, Bagarn claims he did not disappear with the rest of the Dwemer because he was "not currently present on Nirn" or something along those lines. As far as I'm aware, Bagarn is not in ESO at all, but I don't know if he's mentioned or not.
I'm curious what wild theories people might have on the whereabouts of the last known living Dwemer during the events of ESO, some 700-800 years (if my math checks out, which it may not) before he's encountered in Morrowind.
