Kara-Tur: The Eastern Realms

Kara-Tur: The Eastern Realms details a Forgotten Realms campaign setting for use with Oriental Adventures, which describes the eastern land of Kara-Tur and its geography, population, society, government, history, languages, and opportunities for adventure. Like the original Forgotten Realms Campaign Set, this set only lightly details the vast land of Kara-Tur, leaving room for the DM's creativity. 

"Volume I" covers the lands of Shou Lung, T'u Lung, Tabot, the Plain of Horses, and the Northern Wastes (analogs of China, Tibet, Mongolia, and Siberia), while "Volume II" covers the Jungle Lands, the Island Kingdoms, Koryo, Kozakura, and Wa (analogs of Southeast Asia, Malaysia, Korea, and Japan).
