Narnia by invading Archenland. Shasta brings warning of Rabadash's invasion to Narnia, and meets Edmund once again. Edmund gently reminds Shasta that he should not eavesdrop, but is clear that all is well before they march to Anvard to stop Rabadash. Edmund, Shasta, and Corin's father, King Lune of Archenland, lead the fight against the Calormene army and defeat them. Shasta is then recognized as Prince Cor, the long-lost heir of Archenland. Edmund's own redemption lends him perspective during the judgment of Rabadash; despite the fact that Rabadash has acted treacherously, Edmund argues against killing him, saying (in reference to himself) "Even a traitor may mend. I have known one who did." Prince Caspian Edmund and his siblings return to Narnia to aid Caspian, rightful King of Narnia, against King Miraz the Usurper. He convinces Trumpkin the dwarf that they are the Kings and Queens from the legend by defeating him in a sparring practice. He later helps Peter and Trumpkin defend Caspian against Nikabrik, a hag, and a werewolf, which Edmund kills. Edmund is also there to witness Peter's duel against Miraz. In the book Edmund is around 11 years old at the time of their return. He has since become more caring and protective of Lucy, and is the first person to believe her when she sees Aslan, supporting her against the disbelief of Trumpkin and her other siblings. Edmund is shown in a more positive light in this book than in The Lion, The Witch and The Wardrobe. His demeanor is more cooperative and loyal, even under the guidance of Peter, who is unprepared for the new Narnia and its current status. He rarely stands up to Peter openly but often subtly takes charge. In the film, Edmund proves to be much more mature than Peter or Caspian, but he stays out of their arguments. Edmund sneaks into Miraz's castle ahead of the army to signal that it is safe to enter, and later presents Peter's proposition for a duel to Miraz and goads him into accepting, thereby buying them time. Also in the film, he stops the White Witch from being brought back from the dead by forcing his sword into the ice wall through which she is trying to re-enter Narnia, smashing it. The Voyage of the Dawn Treader Edmund, Lucy and their cousin Eustace enter the world of Narnia through a magic painting, and
