- How did Gandalf elude and puzzle Sauron? 2 answers
It seems apart from Saruman, Sauron doesn't pay much attention to the Istari and doesn't do a great deal to try and counter them (aside from corrupting Saruman for his own needs) which comes to my assumption that he may have not been aware they were of the same order as him.
So was Sauron aware his enemies were in fact his equals (albeit they were of a lower order of maiar)?
