So far, in When the Sea Turned to Silver, Pinmei and Yishan are on their way to the City of Bright Moonlight to get the Luminous Stone. On their way there, they see a red butterfly, which is strange in the heavy snow, but think nothing of it. Then, a lady falls off of her snow white horse. They find out she is on her way to the City of Bright Moonlight, and they continue their journey together.
