Thunder Granite Valley was considered as a rather unique place in the Thunder Granite Mountain Range. In the depths of the mountain range, mountain peaks criss-crossed and the topography was fairly complex. It was said that a long time ago, lightning had descended and forcefully ripped apart that mountain peak continuously, before it gradually formed into the Thunder Granite Valley today.
Perhaps because of the lightning’s descent, the entire Thunder Granite Valley was filled with an lightning aura. Numerous Demonic Beasts within the mountain valley mutated due to this. Not only could they come and go like the wind, they could also spit out thunder bolts. Compared to the Demonic Beasts outside, they were far more difficult to deal with.
Thunder Granite Valley was fairly large and even after the sudden influx of such a huge number of humans, it was still tremendously spacious. However, the thick mist that permeated the valley was an extremely major obstruction to one’s sight.
