As you dive through the darkness of Teyvat, you've discovered a vast country, secluded by the depths of sea of Watatsumi...

You began to wander around a nation called Enkanomiya, also formerly known as Byakuyakoku and Tokoyo... the land of white night. A land that suffered The Second Who Came's wrath and punishment.

You eventually find a spirit lying around, as you reach Dainichi Mikoshi. It began to notice you as you walk by.
