Wizards, as they are called, are Maiar, and were sent to Middle Earth to help defeat Sauron. Now, most will say that they are very powerful.
I disagree.
We can tell from passages in the book that Wizards are quite weak without their staffs. It was the staffs that had the power, not the Wizard. Gandalf broke Saruman's staff, Saruman took Gandalf's staff, rendering him powerless, Saruman wants the rods fo the five wizards. The power resides in the staff, not the wizard, obviously. What are your thoughts on this?
