Like you said Yagrum Bagarn was in Morrowind and there was also the Mages Guild quest to research the Disappearance of the Dwarves, it makes sense being in Morrowind as Vvardenfell is the location of Red Mountain.

Morrowind had some history on the Dwemer, Oblivion had the Ayleids and Skyrim the Falmer.
