It had the balls to label a picture of Orthanc as Sauron's tower, even though it is clearly stated in the books that Barad-Dur is Sauron's tower, located in Mordor, and Orthanc is Saruman's tower, located within the circle of Isengard in the Gap of Rohan. I mean, honestly! If you're going to make an educational textbook, at least do some research, am I right?
