The Han languages were a group of languages spoken in Kara-Tur. It comprised a number of languages descended from the root Han language, including Koryo, Kozakuran, and Wa-an, and possibly others. Kozakuran and Wa-an remained closely related; some considered them only different dialects of the same language. There was perhaps 65% comprehension between the two. Thus most folk of Shou Lung, Wa, and even Kozakura found the Koryo language relatively easy to pick up, and most Koryoans in turn found Kao te Shou, Wa-an, and Kozakuran easy to learn as well.
