This river flows out of the Katakoro Shan on the western border of the Katakoro Plateau. The icy waters start from under the Katakoro Glacier and Nor Zanskra. As the waters descend and wind through the hills they fill Nor Takt. As Nor Takt drains to the east the Takt Muren flows east northeast until it reaches the Yellow Serpent Border Cliffs. Here Takt Muren becomes the Yellow Thunder Falls as it plunges over the cliffs.
Beyond this point Takt Muren joins in with other rivers and create the waterways that crisscross Shou Lung.
