*Cross Posted on Archive of Our Own* An ex-mafia member turned detective, Aether can't catch a break. From his sister's disappearance to the serial killer loose on the streets of New Teyvat City, his first case has proven to be more than he can handle. But when coincidence becomes fate, Aether soon discovers that perhaps there's more to this case than what meets the eye. ........................ WARNINGS: This story will portray violence, gore, and death-especially of major characters. This is a murder mystery with a violent serial killer in a mafia universe. I do not own any characters within the story or the art on the cover (although I edited it together): credit goes to Genshin Impact and Canva. Updates based on a whim, most likely once a week.
