The northern edge of the great Yehimal Mountains is known as the Kun-Yen Shan. Here the lofty peaks rise abruptly from the low valley that marks the southern edge of the Katakoro Plateau. Peaks of the Kun-Yen Shan rise up to 23,000 feet. Small glaciers fill the gorges between massifs.
Buried in the jumble of ranges are isolated valleys. These are islands of green hidden from the outside world. Most of these valleys are uninhabited. The deepest are thickly forested, populated by deer, monkeys, leopards, and tigers. Some have a few inhabitants, mostly intrepid humans who have settled in these valleys far from bothersome civilization. A few, however, have more interesting denizens.
