Guhua

Guhua (Chinese: 古华 Gǔhuá, "Ancient Splendor") is a historical and mythological figure in Liyue. It is believed he was an adeptus who, at the end of his journey, ascended and became a star in the midst of a purple haze at Huaguang Stone Forest.
While the Guhua Clan is named after him, he has no direct relation to it; its original form, the Guhua Brotherhood, was established by someone close to Guhua to honor him.
