What can one truly know about a place until he or she has experienced it firsthand? Calimport is a place of many truths, each more disturbing than the last. It is also the most influential trade city in souther Faerûn, whether its detractors admit it or not. Building on materials from Empires of the Shining Sea, this supplement expands tremendously on what we know about the city that has been the seat of Calishite power since the arrival of the djinni lord Calim eight millennia ago. What can be found inside? The history of Calimport on a broad scale, showing the ebb and flow of power surrounding the city across time. A sweeping look at the city itself, including all of its landmarks, wards, and sabbans (districts), providing for the first time the key to finding ways through a city of more than two million people. A close-up view of the Eraré Sabban and its Taorahl Drudach, a waterfront district and neighborhood designed to be a central base in your own Calimport campaigns. Numerous magical items and artifacts, many of which hide among Calimport's shadows, from the Battlecloak of Vycaena and the Codex Thealnakkar to the Staff of Shoon and the Tome of Secrets.
