Gandalf

Gandalf is a wizard, member of the Istari order, as well as leader of the Fellowship of the Ring and the army of the West. In The Lord of the Rings, he is initially known as Gandalf the Grey, but returns from death as Gandalf the White. Gandalf is the last of the wizards to appear in Middle-earth, one who: "seemed the least, less tall than the others, and in looks more aged, grey-haired and grey-clad, and leaning on a staff". Yet the Elf Círdan who met him on arrival nevertheless considered him "the greatest spirit and the wisest" and gave him the elven Ring of power called Narya, the Ring of Fire, containing a "red" stone for his aid and comfort.
