Grey mountains and the Rebel within rebellion

Somewhere else in the Southern Continent, one could see vast chains of complex mountains. Each mountain in the chain was tall to the point that they almost touched the clouds. People called this chain of mountains, the grey mountains because at night, the trees blanketing the mountains glimmered a silver light. The scholars of the Southern continent studied the trees and their leaves, coming to the conclusion that the leaves had a property that absorbs moonlight and produces a vapor that radiates in silver color. In addition to the silver light, the vapor produced by leaves had a cooling effect. The scholars and blacksmiths of the Southern continent were able to create a device that absorbs this vapor, store it within and release it slowly to cool down a room or a hall depending on the device's size.
