The White Witch -
This evil queen of Narnia places a spell on the land so that it is winter and never Christmas. The Witch is the "Emperor's hangman," as Mr. Beaver says, and she has the right to kill any Narnian traitor. She wields a wand that turns creatures and people to stone. The wand also produces the Turkish Delight that enslaves Edmund and makes him greedy. The Witch kills Aslan, and it is only after he rises from the dead that he defeats her. Like any malicious character, the Witch, an embodiment of evil, could represent Satan, or she may be a servant of Satan.
"She calls herself the Queen of Narnia thought she has no right to be queen at all, and all the Fauns and Dryands and Naiads and Dwarfs and Animalsat least all the good onessimply hate her."
