Some of the characters in "The Chronicles of Narnia" series by C.S. Lewis include Peter, Lucy, Susan and Edmund Pevensie; Aslan the lion; Eustace Scrubb, the Pevensies' cousin; Jill Pole, a friend of Eustace; Reepicheep the mouse; and Bree the horse. Many of the characters in the Narnia stories are talking animals and mythological creatures.
In "The Lion, the Witch, and the Wardrobe," the main characters are Lucy, Edmund, Peter and Susan. Lucy is the youngest Pevensie child and the first to enter Narnia. Father Christmas gives her the gift of a healing potion, which she uses to help cure the sick and fallen after the battle with the White Witch. Edmund, who begins the story as a traitor, is forgiven by Aslan and becomes a king of Narnia; his brother, Peter, is crowned High King. Susan, who is known for her beauty, becomes an expert archer and a queen by the end of the story.
Aslan, the great lion, is the most powerful creature in the series and serves as a godlike figure in each book. Eustace Scrubb changes from a bossy, spoiled boy into a hero and first appears in "The Voyage of the Dawn Treader"; in that story, he meets and eventually befriends Reepicheep, a brave mouse. Jill Pole also learns that she can be heroic in "The Silver Chair." In this story, she and Eustace rescue Prince Rillian, who was kidnapped by a witch.
"The Horse and His Boy" tells the story of Shasta, who is secretly a prince of Archenland. He teams up with the vain Narnian horse, Bree, to help stop the Calormene army from invading. Digory Kirke first appears in "The Magician's Nephew" and starts a chain of events that leads to the construction of the magical wardrobe.
