The Watcher of the Mists
Far Tian Xia is a semi-mythical land that lies far to the east. It is also known as the Dragon Empire. Due to its distance, trade with Tian Xia is difficult, and its exotic goods are rare and expensive. There are but two trade routes: the less-traveled goes overland through the trackless deserts of Qadira. The second goes north over the frozen wastes of the Crown of the World.
People of Tian descent are unusual in the Inner Sea region, and are seen as exotic outlanders.
