Boy Without A Conscience

Dainsleif entered the tavern, looking around. Diluc shot him a look, he was confused, this man had a strange energy emitting from him. As Dainsleif finally found what he was looking for, Kaeya, Dain walked up to the man, got onto one knee, and bowed down. He grabbed Kaeya's hand and gave it a light kiss, while still holding his hand to his face, he said, "My prince, i finally found you." Kaeya looked confused, looked around and glanced at Diluc, and mouthed the words 'is this some type of prank?' Kaeya, Diluc, Venti, Rosaria, Barbara, Amber, Eula, Jean, Lisa, Noelle, Albedo, and Klee (who was drinking grape juice) all were there, looking at Kaeya and then the strange man.
"I'm sorry, what?" Kaeya stated, super confused. He looked around, something caught his eye. Venti sobered up all of the sudden, and ran out of the tavern.
"My prince, I am your protector, it was my fault i didn't protect you from that archon when you were younger," Dain confessed, "I am back to protect you, over the years we have rebuilt our hometown, please, do come back, we need a ruler."

A few years later, they find out that Kaeya's body belongs to a special someone, and things don't go well for the place of Teyvat.
