Peggy, whose real name is Margaret, is a very strong torch, which means that she can psychically see the future, as well as see what is going on in other people's minds. Because of this, she has the knowledge of an adult even when she is a small child. When Peggy prophesies that Alvin will be a Maker, she also sees that she must always watch over him, protecting him with the flap of skin left over from his birth. Peggy is a quiet, sullen child, because she is terrified of spilling the secrets of the people around her. She has made a promise that she will never tell a lie. Peggy feels tied to a future of misery, until the day she realizes that she has the power to change her own destiny. Peggy trains with Mistress Modesty, who teaches her to value herself for her own inner beauty, and also trains her to shut out the thoughts of others, so that Peggy finally learns to interact normally with other people. When Peggy disguises herself as an old lady, she calls herself Miss Larner. Even more than she wants to marry Alvin, Peggy wants to help create his dream of the Crystal City.
