This unexpected group of three was not having any trouble moving around the area. They all were strong enough to handle the broken rocks which has clearly been a result of the world returning to the flow of mana and expanding. However, they were not very happy with the fact that there were many sharper rocks.
This presented evidence that there would be more terrain based dangers all over the world since the rocks here had been hard, but when broken, had created razor sharp edges. The same could have happened elsewhere in the mountains. This meant that every mountain could be a very dangerous place to travel all around.
It also meant that any place which had been hard to travel before could have become much harder now. The icy terrain in the very far north could have broken up which was not something simple. It had been frozen and the same for many years. Therefore, the cracks and holes formed could be hidden under snow.
