Dori: Mr. Gandalf, can't you do something about this deluge?
Gandalf: It is raining, Master dwarf, and it will continue to rain until the rain is done. If you wish to change the weather of the world, you should find yourself another wizard.
Bilbo Baggins: Are there any?
Gandalf: What?
Bilbo Baggins: Other wizards?
Gandalf: There are five of us. The greatest of our order is Saruman the White. And then there are the two Blue Wizards... You know, I've quite forgotten their names.
Bilbo Baggins: And the fifth?
Gandalf: Well, that would be Radagast the Brown.
Bilbo Baggins: Is he a great wizard, or is he more like you?
Gandalf: Well, I think he is a very great wizard... in his own way. He's a gentle soul who prefers the company of animals for others. He keeps a watchful eye over the vast forest lands to the East, and a good thing too. For always evil will look to find a foothold in this world.
