Part 5/8:
Most fans of Tolkien are familiar with the three wizards seen in adaptations: Gandalf, Saruman, and Radagast. However, two additional wizards, known as the Blue Wizards, existed in the lore. Their fate and roles remain largely undefined, with conflicting beliefs about whether they fell into corruption or fought valiantly against the enemy.
In Unfinished Tales, it is suggested that these two contributed to dark cults beyond the reach of Sauron’s downfall. Tolkien's letters suggest that he viewed the Blue Wizards as having failed in their mission, raising questions about their influence and actions during crucial historical events in Middle-earth. The lack of clarity surrounding their stories leaves much for readers to imagine.
