In the northwest reaches of Calin Mountain, there was a natural mountain valley. The entrance of the mountain valley faced the north and spanned a thousand feet.
As it extended inwards, it became increasingly narrow. The entire mountain valley was shaped like a funnel, and it continued into the hillside until the width was only about 10 feet or so.
When gale winds blew from the north of Calin Mountain, they were blocked by Calin Mountain and formed a tremendous wind pressure and air current that flowed down the funnel-shaped valley. As it went inwards and the mountain valley became narrower, the speed and pressure of the wind increased with each step!
Before the Seven Profound Martial House was established, this mountain valley had been named Gale Valley. Inside the valley were large rolling stones that blew everywhere, and humans and livestock found it hard to stand firm.
