Edmund Pevensie betrays his siblings to the White Witch in C.S. Lewis’s The Lion, the Witch and the Wardrobe.
Edmund is the second of the four Pevensie children. After entering Narnia, he meets the White Witch, who tempts him with enchanted Turkish delight and promises power. Edmund tells her about his siblings and helps her locate them, although his actions are driven by manipulation, resentment, and ambition rather than simple villainy.
His betrayal becomes the moral turning point of the novel. Aslan intervenes when the Witch claims Edmund under Narnian law, and Edmund’s rescue is followed by repentance and reconciliation. He later fights for Narnia and becomes known as King Edmund the Just.
Edmund’s arc is often confused with that of Eustace Scrubb, another Narnia character who undergoes a major transformation in The Voyage of the Dawn Treader. Edmund appears in several books, but the betrayal and redemption storyline begins in The Lion, the Witch and the Wardrobe.
