• Prunaprizmia's story line was entirely added. Partially to answer the question of what happened to her and her son after their brief mention in the book and partially to add another female character into a mainly male dominated story.
• Reepicheep (the mouse knight) plays a minor role in 'Prince Caspian', but when writing began he was written out. He was omitted because his role was relatively small and despite being a memorable character from the book, he didn't really do much. (He is set to appear in Series 2, based on 'The Voyage of the Dawntreader.')
