The Widow Harun
Kara-Tur is the eastern third of the largest continental landmass on the surface of Toril, bordered on the west by The Endless Waste and on the southwest by The Utter East, gateway to Zakhara. Kara-Tur is the area in which the Oriental Adventures Campaign Setting takes place. This material is little used in The Widow Harun. However, Kara-Tur occasionally makes a cameo appearance. For example, The Golden Way is a caravan road connecting the empire of Shou Lung in Kara-Tur with the nation of Thesk in The Western Realms of Faerun. In addition, Kara-Tur has exercised a great influence on the ways of life and material culture of The Endless Waste.
Some elements from Kara-Tur are described in much more detail in the Forgotten Realms core books and supplements. Please consult these if you wish to learn more.
