From the front of the book:
In a land of assassins, djinn, giant birds, and magic lamps, the heroes find themselves pursued all the way to the gates of Almraiven, and quickly discover that there are those who will stop at nothing to prevent Ala'Ammar from getting his hands on the precious artifact that will restore honor to his family and could even deliver freedom to the oppressed people of Calimshan. A Living Forgotten Realms adventure set in Calimshan for characters of the Heroic tier (levels 1-10). This is the third and final part of the Battlecloak Saga (which also includes CALI3-1 and CALI3-2). Playing these three adventures in order with the same character is strongly recommended, but not required.
