[The Elf-warrior]

I wish Sauron wasn't evil.

Your wish is granted. That means the Lord of the Rings was never written. Instead Tolkien wrote The White Hand. It's about a renegade Maia who tries to take over Middle-earth. When PJ turned it into a movie he turned Saruman into a literal white hand.

I wish Tolkien recorded how old Durin the Deathless was when he died.
