With such origins, it is understandable that the most powerful wizard in Middle-earth was scared!
How not to remember the iconic scene of the Lord of the Rings: The Fellowship of the Ring during which Gandalf (Ian McKellen) uttered the famous reply: “You will not pass !” ? A sequence as mythical as it is epic which nevertheless demonstrated the fear of the Gray Sorcerer in the face of such a creature. And for good reason, when we know the origins of Balrog through the literary saga created by JRR Tolkien, they are enough to terrify the most powerful magicians of Middle-earth. If its form could obviously explain the fear felt by Gandalf during their duel, several details about the Balrog’s past, starting with his Maiar origins could also explain such a fear. To understand here that Gandalf and the Balrog are in reality linked by their common origins in the saga. Being both pre-Earth angelic entities, the latter helped create the environment of the Lord of the Rings that we know today.
However, some minds have been corrupted by Melkor and Mairon, two particularly influential and charismatic Maiar, also responding to the names of Morgoth and Sauron. When Gandalf faced the Balrog in The Fellowship of the Ring, he encountered an entity of a force far more powerful than anything that existed then on Middle-earth and who fought in many bloody battles. Moreover, the Gray Sorcerer having arrived during the Third Age, he has much less power in his body than a former Maia who became Balrog, who appeared during the First. All these unseen details about the past of these demons could therefore explain the fear of the famous sage facing this creature despite the fact that he has finally succeeded in defeating it. Moreover, this is not the only mystery solved in the saga of Lord of the Rings around Gandalf’s duel against the Balrog because we also know how the magician and the monster managed to climb to the top of the mountain at the end of their fight!
