Description:

A fin taken from a defeated Xuanwen Beast's back.

The soft, moonlight-esque glow on the fin gives off a sense of serenity. There's a saying that goes "jade flows through the void as the Xuanwen lights the shadows." No matter how much time has passed, the beasts roaming the mountains will always remember the moonlight, just as they do their secrets, hidden within the shadows and the night breeze.
