You will give me the Ring freely?  In place of the Dark Lord you will set
up a Queen.  And I shall not be dark, but beautiful and terrible as the
Morning and the Night!  Fair as the Sea and the Sun and the Snow upon the
Mountain!  Dreadful as the Storm and the Lightning!  Stronger than the
foundations of the earth.  All shall love me and despair!
