The fictional land visited by the Pevensie children in C.S. Lewis's Narnia novels is Narnia. It is the central setting of The Chronicles of Narnia, a seven-book fantasy series published between 1950 and 1956.
Narnia contains talking animals, magical beings, humans, and rulers drawn from several mythological traditions. The lion Aslan is its principal creator and spiritual guardian, while the Pevensie siblings arrive from England through magical gateways at different points in the series.
Narnia is not the name of the entire universe. Lewis's stories also include locations such as Earth, Charn, and the Wood between the Worlds. The title The Chronicles of Narnia refers to the history of the land rather than to a single adventure or one royal family.
