Winters have been getting colder and longer the past few years, posing mounting problems for the people of the valley of Rin.

When the Bukshah are fenced, they cannot go up the mountain to eat the seals on the ice creeper nests, preventing the numbers from growing and the habitual spreading.

When the Bukshah are free to roam, they make an annual pilgrimage to the mountain and keep the ice creepers under control, preventing the rise of a cold time.

Fearing other attacks the three followed the Bukshah into the heart of the mountain where they were trapped by the landslide that destroyed the Valley as they knew it.
