Maiar in the context of "Evil in Middle-earth"

Gandalf is a protagonist in J. R. R. Tolkien's novels The Hobbit and The Lord of the Rings. He is a wizard, one of the Istari order, and the leader of the Company of the Ring. Tolkien took the name "Gandalf" from the Old Norse "Catalogue of Dwarves" (Dvergatal) in the Völuspá.

As a wizard and the bearer of one of the Three Rings, Gandalf has great power, but works mostly by encouraging and persuading. He sets out as Gandalf the Grey, possessing great knowledge and travelling continually. Gandalf is focused on the mission to counter the Dark Lord Sauron by destroying the One Ring. He is associated with fire; his ring of power is Narya, the Ring of Fire. As such, he delights in fireworks to entertain the hobbits of the Shire, while in great need he uses fire as a weapon. As one of the Maiar, he is an immortal spirit from Valinor, but his physical body can be killed.

The Ainulindalë (Quenya: [ˌai̯nuˈlindalɛ]; "Music of the Ainur") is the creation account in J. R. R. Tolkien's legendarium, published posthumously as the first part of The Silmarillion in 1977. The Ainulindalë sets out a central part of the cosmology of Tolkien's legendarium, telling how the Ainur, a class of angelic beings, perform a great music prefiguring the creation of the material universe, Eä, including Middle-Earth.The creator Eru Ilúvatar introduces the theme of the sentient races of Elves and Men, not anticipated by the Ainur, and gives physical being to the prefigured universe. Some of the Ainur decide to enter the physical world to prepare for their arrival, becoming the Valar and Maiar.

Tolkien wrote the initial version of the Ainulindalë between November 1919 and the spring of 1920 as "Music of the Ainur", and then completely rewrote it in 1930. He continued to make further revisions throughout his life. The early version was eventually published by his son Christopher in The Book of Lost Tales 1.

Magic in Middle-earth is the use of supernatural power in J. R. R. Tolkien's fictional Middle-earth. Tolkien distinguishes ordinary magic from witchcraft, the latter always deceptive, stating that either type could be used for good or evil.

Several of the races of Middle-earth are inherently able to work magic, from the godlike Ainur (including Wizards and Balrogs, both being members of the angelic race of Maiar) and the immortal Elves to Dragons and to some extent also Dwarves. Men and Hobbits could not directly work magic, but could make use of more or less magical artefacts made by others, such as Númenorean swords (made by Men with Elvish blood) and the Phial of Galadriel given to Frodo. Some of the magical artefacts were of great power, including the Palantíri or Stones of Seeing, but by far the most powerful was the One Ring, made by the Dark Lord Sauron and embodying much of his former power.
