The fictional world that is the setting of C.S. Lewis’s Narnia books is Narnia. It is a richly imagined realm populated by humans, talking animals, dwarfs, giants, fauns, and other mythical beings.
Narnia is governed by its own history and geography, including forests, seas, islands, and neighboring lands such as Archenland and Calormen. The world’s history begins with its creation in The Magician’s Nephew and ends with its destruction in The Last Battle.
Children from Earth often enter Narnia through magical gateways. These gateways include a wardrobe, a painting, magical rings, and a railway accident. Time also behaves differently there, so characters may experience very different amounts of time in Narnia and on Earth.
Narnia is sometimes confused with the title of the whole series. The Chronicles of Narnia is the book series; Narnia is the principal fictional world inside it. Aslan, the Pevensie children, and many of the series’ major events are connected to this setting.
