Great Desert

Great Desert lies between Calormen and the northern countries of Archenland and Narnia. It can be crossed on horseback in about a night and a day. The desert provides some protection from Calormen invasion since the springs at the great oasis would not be sufficient to enable an army of any size to cross it. There is however a secret and well watered valley leading into Archenland. Fortunately for the northern lands this is not known to the Calormenes who are forced to rely on surprise attacks by relatively small cavalry forces. Since no one from any state (including Calormen) lives or operated there,it is technically, but very informingly a state of its own.
