I know this is a joke, but what about the Xianzhou characters that are Abundance? There's like three of them.
Lore path with game path is different, lore wise everyone in Xianzhou following Lan, dunno about the dragon kin tho, they sound still worshipping Long.
I actually think thats a mamianqun worn sideways, judging from the thin pleats and large pleats on the sides. Its not an incorrect way to wear it and was actually very common during some dynasties. The red robe also looks like Zhijupao.
