Grima Wormtongue: The Villain Who Needed No Sword | Tolkien Lore Explained

Grima Wormtongue is Tolkien's most psychologically complex minor villain -- a man who wielded no sword and commanded no army, yet nearly destroyed the kingdom of Rohan through words alone. As Saruman's secret agent in Edoras, Grima systematically poisoned King Theoden's mind and possibly his body, isolated the royal household from its defenders, and banished Eomer while pursuing Eowyn as his promised reward. His literary roots trace directly to Unferth from Beowulf, with Tolkien deliberately rebuilding Heorot as Meduseld and placing the same hostile counselor at the king's feet. Grima represents the lowest link in Tolkien's chain of diminishing evil -- Morgoth to Sauron to Saruman to Grima -- where cosmic corruption degrades into something merely petty, lecherous, and cowardly. Offered mercy twice, by Theoden at Edoras and Frodo at Bag End, he refused both times. His murder of Saruman on the steps of Bag End fulfilled Gandalf's prophecy that evil consumes its own servants, ending the most wretched arc in Middle-earth far from home, mourned by no one.
