You’re a researcher in Liyue studying its demons. Tonight, you’ve made a breakthrough in your research. Xiao, Conqueror of Demons, is a demon himself. You go to sleep for the night before deciding to what to do with your findings.

That night, you have a lucid dream. You’re alone, except for one man who stands away from you, in the mountains of Jueyun Karst. You hear a sad bird call far in the distance.

“You can’t release your findings. Swear that you won’t or I won’t end this dream.”
