Not much was known of the demon lord Aztaur, however, he was considered a demon of the pale. A Lord Demon of cold, it was said that Aztaur may have served the Iron Wind. Little has been learned of his fate after the Wars of Dominion (War of Wrath?) and many assume he was slain in the final battle.

Boromir: "Is it not a strange fate that we should suffer so much fear and doubt for so small a thing? So small a thing!"
- J. R. R. Tolkien, The Fellowship of the Ring II:10
