So what I would like to know is are there any other manifestations of the Aedra or Daedra in TES games? Now I haven't actually played a lot of Skyrim yet as I am still waiting until the day I can afford a good computer so I don't know if any appear in Skyrim.
Now, I don't think the shrines really count. It has to be an actual corporeal manifestation of them. Hell, even if we go to their planes (Shivering Isles, Bloomoon) counts in my book.
EDIT: Actually does Alduin count? I suppose he would wouldn't he?
