Crystal Ice, daughter of the horrible White Witch, Jadis, has always hated her mother's evil ways. She sees her chance to run when Edmund, king of Narnia, is captured. She rescues him and brings him to where she knows the Narnians set up camp. She doesn't expect to be accepted, and she isn't at first, but Aslan trusts her, so all the soldiers do as well. King Peter, however, has yet to trust her and protests when she becomes him and his sibling's protector.
