Few wizards have so deeply embedded themselves in the public consciousness like The Lord of the Rings‘ irascible Gandalf. Considered by many to be one of the most powerful wizards in film, Gandalf casts a striking figure on-screen and on the page as he shepherds two generations of Bagginses on some of the most fateful journeys any hobbit has ever undertaken.

For all his implied power, though, Gandalf rarely does much worth describing as “magic,” especially for someone calling himself a wizard; yet that is by design, because Gandalf is so much more than just a conjurer of cheap tricks – he’s one of the Maiar, Middle-Earth’s equivalent of an angel. Gandalf and all his fellow Istari, including the traitor Saruman, are Maiar, sent as messengers and teachers for the mortals of Middle-Earth by the divine Eru Ilúvatar. As one of the Maiar, Gandalf is both far more and far less powerful than he appears to be.

Being One Of The Istari Makes Gandalf Immortal In The Lord Of The Rings

Middle-Earth’s Order Of Wizards Are More Than Just A Group Of Doddering Old Men

The five Istari of The Lord of the Rings were sent to Middle-Earth around the year T. A. 1000 to guide mortals in their resistance against the Dark Lord Sauron. Sauron himself was actually one of the Maiar as well, yet he was far more powerful individually than any of the Istari, and the Istari were banned from directly interfering in events; they were restricted to serving as counselors and sages. In fact, “Istari” translates from Tolkien’s constructed Elven language of Quenya to “wise ones,” or literally “those who know.”

Amazon’s The Rings of Power series shows Gandalf and at least one other Istar arriving on Middle-Earth during the Second Age; this doesn’t technically violate Lord of the Rings canon, as it’s only specified that the arrival of the five Istari together as a group happened in the Third Age.

As an Istar, Gandalf was functionally immortal, similar to the Elves; his body was merely a vessel to hold his spiritual essence. In fact, Gandalf – or rather his true Maiar self, Olórin – was older than the world itself, having been created by Ilúvatar in the Void along with the rest of the Maiar and their greater siblings, the Valar. Olórin helped protect the first Elves from the predations of Melkor, the first Dark Lord, in the dawning days of the world. So, by the time of The Lord of the Rings, Gandalf is over 16,000 years old.

While Gandalf Is Immortal, His Physical Body Is Not

There Is A Difference Between Immortality And Invulnerability

Again, as with Elves, Gandalf’s immortality only shielded him from the passage of time; his body, as a shell, could be injured or even destroyed, as it was in the course of his slaying the Balrog known as Durin’s Bane atop the peak of Zirakzigil. Gandalf the Grey died upon that mountain, next to the body of his foe, and the spirit of Olórin returned to the embrace of Eru Ilúvatar.

Olórin was the only Istar to remain true to his mission.

Yet the benevolent One who created the world saw that the people of Middle-Earth still had need of the Wise, and since Olórin was the only Istar to remain true to his mission, Eru wove a new body for his loyal servant, and Gandalf returned to Middle-Earth. Gandalf was profoundly changed by his resurrection, not in the least by the circumstances of his return.

While the Istari as a group had been forced to hide the greatest part of their divine power, now Gandalf was the only true Istar remaining on Middle-Earth as a true Servant of the Secret Fire, and so Ilúvatar allowed him to wear more of his power openly. This is why he took up the mantle of Gandalf the White; he became the Wise One that Saruman should have always been, and in doing so ensured that The Lord of the Rings‘ true protagonists – Frodo Baggins and Sam Gamgee – completed their quest to destroy the One Ring for good.
