Part 6/8:
In contrast to the film adaptations that show Théoden as being possessed by Saruman, the literary depiction is more nuanced. In Tolkien's text, Théoden was not outrightly controlled by dark magic. Instead, his advisor, Gríma Wormtongue, gradually poisoned both his mind and body, taking advantage of the king's exhaustion and age. As Théoden succumbed to fatigue, he became susceptible to Gríma's manipulative tactics, which served Saruman's malicious plans.
Ultimately, it was Gandalf who saved Théoden from this deterioration. Upon arriving in Rohan, Gandalf used his wisdom and strength to heal the weary king, freeing him from Gríma’s spell and restoring him to his former strength. This liberation marked a pivotal moment in the lead-up to the war against Sauron.
