The Calormene Conquest of the nation Narnia was the final conflict to occur in the World of Narnia, in the Narnian-year 2555, ending at the famous Battle of Stable Hill. The planning of the conquest was, perhaps, the greatest conspiracy in Narnian history. While a "False Aslan" roamed the countryside, a lone ape, Shift, was plotting with Rishda Tarkaan, a relative of the unnamed Calormene Tisroc at the time, to capture Narnia for the Calormene Empire, to enslave its peoples and to exploit its natural resources. Rumours of Aslan's presence pulled Narnia's King Tirian away from his castle at Cair Paravel in the hope of meeting him.
