Dagoth Ur, as he was in the Third Era, was, like his supposed kin, an 'Ash Vampire.' One of my questions is: Was Dagoth always of this peculiar Ash Vampire race? Was this race as it was during the Battle of Red Mountain (which I assume Dagoth's Ash Vampire kin fought in as well.)
My other question is... what are Ash Vampires? Are they a race of themselves? Were they one chimer, but instead of being turned into dunmer, they were cursed with another form for their especial treachery? I can't remember any text in Morrowind, or any other of the pool of literature on Tamriel I have read.
Insight would be appreciated.
EDIT: I apologize for the somewhat butchered sentence structures in the above paragraphs.
