Terra Year 775, January 16th.
The New Year holidays are over. It's better to say that this era is still not quite accustomed to the so-called seven-day break. People feel restless when not working. City dwellers might gather to chat or play games, while mountain dwellers continue their tasks.
A small team of mountain people is advancing on a vast icy plateau, over four thousand meters above sea level, in the core area of the Bison Mountain Range.
The Bison Snow Peak once—at least during the previous civilization era—was a plateau.
In the time when 'Terra Continent' was not the only continent on this planet, it faced an immense island on another tectonic plate. The Bison Mountain Range was the result of plate collision.
Due to the Calamity of Heavenly Fall, the plateau collapsed, the mountains descended, the continent submerged in roaring great waves, and the Bison Mountain Range rose once more from such an impact.
The past plateau turned into mountain peaks.
