From the publisher's website:
Who would be so foolish as to travel from one end of the world to the other without a trusty map to lead the way? With this map folio, you'll find three invaluable maps for running the Jade Regent Adventure Path—yet these maps can serve any campaign that heads beyond the borders of the Inner Sea into the northern continent known as the Crown of the World or the vast continent of Tian Xia—the so-called Dragon Empires.
Within this map folio, you'll find three huge 8-panel poster maps—one of the city of Kassai (the capital city of the empire of Minkai), one of the frozen reaches of the Crown of the World, and one of the entire continent of Tian Xia from the chill steppes of Hongal to the north to the trackless monster-infested Valashmai Jungle far to the south. Even if you aren't running the Jade Regent Adventure Path, the maps inside reveal for the first time two more of Golarion's continents—realms filled with countless opportunities for exotic new adventure!
