Saruman
The Lord of the Rings
The Lord of the Rings describes a quest to destroy the One Ring, a powerful and evil talisman created by the Dark Lord Sauron to control the nine rings of men, the remaining rings of the dwarves (originally seven) and the three of the elves, the most powerful, thus furthering Sauron's dominion over Middle-earth. Sauron lost the Ring in battle thousands of years before the beginning of the story, and it is now held in secret in the Shire by the hobbit Bilbo Baggins, who passes it on to Frodo Baggins, one of the story's protagonists. Early in the first volume, The Fellowship of the Ring, the wizard Gandalf describes Saruman as "the chief of my order" and head of the White Council that forced Sauron from Mirkwood at the end of Tolkien's earlier book The Hobbit. He notes Saruman's great knowledge of the Rings of Power created by Sauron and by the Elven)-smiths. Shortly afterwards, Gandalf breaks an arrangement to meet Frodo and guide him out of the Shire to Rivendell to keep the Ring safe from Sauron's agents.

Frodo and Gandalf are reunited at Rivendell midway through The Fellowship of the Ring. The wizard explains why he failed to join Frodo: he had been summoned to consult with Saruman but had been held captive. Saruman initially had proposed that the wizards ally themselves with the rising power of Sauron in order to eventually control him for their own ends, revealing himself as a traitor. Saruman went on to suggest that they could take the Ring for themselves and challenge Sauron. When Gandalf refused both options, the traitorous Saruman imprisoned him in the tower of Orthanc at Isengard, hoping to learn from him the location of the Ring. Whilst on the summit of Orthanc, Gandalf observed that Saruman had industrialized the formerly green valley of Isengard and was creating his own army of Half-Orc)/Half-Man) fighters and Wargs) to rival Sauron. Gandalf's escape from the top of the tower on the back of a Great Eagle) left Saruman in a desperate position, as he knew he would now be known as traitor to his former allies, but was unable to procure the Ring directly for himself and therefore could not hope to truly rival Sauron. Shortly after arriving in Rivendell, Gandalf informs the Council of Elrond about Saruman's betrayal.

In The Two Towers, the second volume of the story, Orcs from Saruman's army attack Frodo and his companions, and carry off two of Frodo's closest friends, Merry and Pippin. The two escape into Fangorn Forest, where they meet the Ents, protectors of the trees, who are outraged at the widespread felling of trees by Saruman's Orcs. Meanwhile, Saruman prepares to invade the kingdom of Rohan), which has lain exposed ever since he had his servant Gríma Wormtongue render Théoden, Rohan's king, weak and defenceless with "subtle poisons". Gandalf frees Théoden from Wormtongue's control just as Saruman's army is about to invade.
