There's also the witch herself. She was from a different and dying world before she ended up in Narnia (as Aslan was creating it.) The lantern that the kids in Magician's Nephew carry turns into the lamp post we see in TLTW&TW. The young boy becomes the professor. He gains an apple from Narnia that grows into a tree that later becomes the wardrobe. There are so many continuity pieces that are beautifully setup by Magician's Nephew and the author of this article really doesn't know enough about the books if they thought otherwise. 😅 Though I may be biased cuz Magician's Nephew is my favorite.
