Jadis in the original book
Queen Jadis, also known as the White Witch, simply known as Jadis, is the main antagonist of The Chronicles of Narnia: The Lion, the Witch, and the Wardrobe. Jadis was the sole living resident and the self-declared final Queen of the world of Charn. She was an extremely powerful sorceress, and was once the most infamous and pyromaniac ruler of Narnia.
Queen Jadis was the evil, sadistic, cruel, and tyrannical self-proclaimed Queen of Narnia, who cast an incredibly powerful spell over the entire land of Narnia so that it is always winter and never, ever, ever any other season, nor Christmas. This magic spell was so strong that it lasted for a full century. As a tremendously powerful sorceress, capable and trained of dark magic, Queen Jadis wielded a much fearful wand through which she could transform anyone who opposed her into ice and stone.
