In a thousand-year winter, praying for spring.
The wind that was supposed to herald the end of winter ceased to blow, and the snowmelt no longer nourished the earth.
Spring-awaiting summer never arrived, and the autumn that follows summer forgot its turn in the cycle.
Thus, the world was locked in a never-ending winter.
No one now remembers that at the beginning of that winter, there was a single white snake.
People have learned to live with the snow, building cities on the frozen earth and finding their own lives within the winter.

Where crimson plum blossoms bloom in the snow, there lives a Xianjun who has watched over the imperial family since ancient times.
An ayakashi in the form of a white snake, given his name by the first emperor. Ruilan, the Xianjun who has lived a thousand years and knows spring, and Guest, the heir to the throne born without ever knowing it.
