The four Pevensie children are the best known: Peter Pevensie (High King Peter the Magnificent), Susan Pevensie (Queen Susan the Gentle), Edmund Pevensie (King Edmund the Just), and Lucy Pevensie (Queen Lucy the Valiant). All of them appear in "The Lion, the Witch and the Wardrobe" and in "Prince Caspian". Edmund and Lucy appear in "The Voyage of the Dawn Treader" and three (all except Peter, who is out fighting giants on the northern frontier) appear as adults in "The Horse and his Boy".
