Departures from the book include new characters and shifts in items to create player "quests"—such as finding the pieces of Andúril scattered across the lands west of Rivendell to reforge Aragorn's sword, whereas in the book Aragorn had all fragments. The most significant change is in the climax, where Frodo and Sam are carried off by a Nazgûl to the tower of Dol Guldur, and the rest of the Fellowship must solicit the help of the Elves of Lothlórien and Radagast the Brown, a wizard, in order to infiltrate the tower and save Frodo before the Witch-king carries him away to Mordor. Strangely enough, events in Lothlórien are actually quite true to the book, including the mirror of Galadriel and a quest to find all the gifts she gives the Fellowship.
