Archenland is a mountainous country south of Narnia. It is bordered on the north by Narnia and on the south by the Winding Arrow river. The seat of government is at Anvard, in the heart of the country. It is described as being somewhat open parkland, with many different varieties of trees scattered far enough apart so as to not constitute a forest – but it is mostly a mountainous country.

Calormen is a semi-arid empire in the south of the world of Narnia. Notable geographic features include the Flaming Mountain of Lagour (a volcano) and the Great Desert. The Great Desert is in the northern part of the country, and the difficulty of crossing it discouraged the Calormenes from invading Archenland and Narnia. The capital of Calormen is Tashbaan, located on an island near the mouth of the River of Calormen, which flows from west to east in the north of Calormen, just south of the Great Desert. Gardens and pleasure houses line the river valley for several miles above the city. North of the river, on the margins of the desert, lie the royal tombs.
