they were given by Father Christmas. Peter takes his sword, Rhindon, and his shield, and again serves as the leader of the group. They eventually meet Trumpkin, a dwarf who helped protect Prince Caspian X from his uncle's Telmarine army, who accompanies them on their journey to meet Aslan. When the children are forced to make a decision, Peter, as High King, has the final word. In order to stall the war long enough for Lucy to find Aslan and awaken the Narnians, Peter claims the right to a one-on-one duel with the Telmarine king, Miraz. After the Pevensie children help defeat the Telmarines, Peter formally gives Caspian the authority to rule a free Narnia. Aslan gives Caspian the authority to "rule under Us and under the High King". Peter later confided to Lucy and Edmund that he was told by Aslan that he and Susan will never return to Narnia, as they are now too old, and have learned all that they can from that world. The four children returned to their world, in which they were waiting for their trains to go to their respective boarding schools. It is learned in this book that Lucy is his favorite sister, a fact that was fairly obvious throughout the series.

In the film The Chronicles of Narnia: The Voyage of the Dawn Treader, Peter makes a cameo appearance at a party. When Lucy transforms herself into Susan, neither Peter nor Edmund know of Lucy or Narnia. In The Last Battle Peter has a minor role in the story. He was the only one to address Tirian, the king of Narnia at the time, in Tirian's vision of the Seven Friends of Narnia. After attending a dinner with the other Friends, Peter and Edmund went to London to retrieve the magic rings that Professor Digory Kirke buried in the Ketterleys' yard, hoping to use them to get Eustace and Jill to Narnia. Both were waiting for Lucy, Eustace, Jill, Digory, and Polly at the station platform when the train crashed
