Searching in the Mountain

According to Gelton and Ophra, this bizarre mountain path could sense approaching outsiders as if it was conscious of its surroundings. Even if only one knight stepped on the mountain road, it could cause the road to collapse. Plus, the spot where it collapsed was very accurate: only the stones below the outsider's foot would collapse. According to the soldiers fleeing back, a landslide like this was as strange and unnatural as the appearance of the Sky Road. It was as though the mountain rock was consciously shaking insects and ants off its body, so the soldiers were terrified. The whole Sky Road kept changing shape, therefore the locals were unable to figure out the collapse as well as the bizarre miasma that filled the air in the area. These were the reasons why the knights had not been able to capture the place. Although there was no "enemy" stationed there, it was more impregnable than any pass.
