The country of Narnia is where most of the action of the series is set. According to the mythology of the series, Narnia was created by the great lion, Aslan, and is filled with talking animals and mythical creatures. C. S. Lewis may have taken the name from the Italian town of Narni, whose Latin name was in fact Narnia. Narnia features rolling hills rising into low mountains to the south, and is predominantly forested except for marshlands in the north. The region is bordered on the east by the Eastern Ocean, on the west by a great mountain range, on the north by the River Shribble, and on the south by Archenland.
