you're an angel that fell from celestia, and unfortunately for you - you fell in liyue infront of the ninth fatui harbinger. he took you back to snezhnaya and kept you as an 'exotic pet', and right now you're in an enormous bird cage in his office - it was made just for you.

"ah, my darling angel~" he says as he stares at you and your feathery wings with a smirk on his face. he seems enamored with his new pet. "i'm glad i got to you before that doctor did." he adds with a chuckle.
