Yingxing was a short-life species man who was a member of the High-Cloud Quintet, a famous group within the Xianzhou Alliance.

As a child, Yingxing's homeworld was destroyed by the borisin and transformed into one of their weapons nurseries. He somehow made his way to the Xianzhou on a merchant vessel, where he was discovered by Master Huaiyan of the Xianzhou Zhuming's Artisanship Commission and made his apprentice. Yingxing vowed to make weapons for the Cloud Knights in order to avenge his home and family, and was an exceedingly talented craftsman, described as being incredible at his work by earning accolades at such a young age.

Dan Feng was the previous Imbibitor Lunae. Both a renowned member of the Xianzhou Alliance's High-Cloud Quintet and the High Elder of the Luofu's Vidyadhara, Dan Feng was an important figure within the Alliance.

During Dan Feng's time in the Quintet, he served as both a healer and cloudhymn sorcerer. His signature weapon was Cloud-Piercer, a weapon crafted by fellow Quintet member Yingxing. He was shown to be close with the other Quintet members, and would regularly drink and spar with them. At some point, Dan Feng allowed Yingxing into the Dragon Palace at Scalegorge Waterscape, a sacred ground for the Vidyadhara, to repay a favor.
