Frodo Baggins and the Fellowship continue their quest to destroy the One Ring and stand against the evil of the dark lord Sauron. The Fellowship has divided and now find themselves taking different paths to defeating Sauron and his allies. Their destinies now lie at two towers - Orthanc Tower in Isengard, where the corrupted wizard Saruman waits and Sauron's fortress at Baraddur, deep within the dark lands of Mordor.
