The Two Towers continues the story begun in The Fellowship of the Ring. Following the breaking of the Fellowship, which was commissioned to carry the One Ring to Mordor and destroy it, Aragorn, the heir to the kingdom of Men, Gimli the dwarf, and Legolas the elf begin a search for the hobbits Merry and Pippin, who have been abducted by Orcs, servants of evil. During the search, they encounter the Riders of Rohan, mounted warriors who warn them that the forces of Sauron - the Dark Lord searching for his lost Ring - and Saruman, the wizard who betrayed Gandalf and the rest of his order, hungry for power for himself - threaten King Thoden of Rohan, and the freedom of his people. Simultaneously, Merry and Pippin, having escaped from the Orcs in the forest of Fangorn, meet Treebeard, an Ent, or "tree herder." Treebeard informs them that Saruman has earned the forest's wrath by destroying trees to fuel his war machinery. Merry and Pippin witness the Ents' decision to go to war against Saruman, and the outcome of that decision. These scattered members of the Fellowship - including one unexpected, but most welcome, returning member - reunite in the effort to free King Thoden and Rohan from the threat of Saruman. A greater threat presents itself, however, when Sauron's forces begin their final assault on Minas Tirith, where the armies of Men will make a last stand against the evil forces of Mordor. As the Fellowship rushes to the aid of Minas Tirith, Frodo the Ring-bearer and his loyal servant Sam seek a way into Mordor. They capture Gollum, who owned the Ring years before and who still desires it. Gollum agrees to guide them into Mordor by a secret way, but Frodo and Sam ultimately follow him into a situation that once more places the fate of their quest in jeopardy. The Lord of the Rings concludes in The Return of the King. Interactive CD-rom.
