Modern AU: Years have passed and Dunwall has survived past it's Steam Age. It's been a long time since Corvo prowled these streets. But it's said that those with the Outsider's mark will return for as long as they are deemed amusing. Maybe it's time Corvo makes his comeback. (Corvo reincarnated! I've taken some liberties. Corvo/Outsider, suggested Corvo/Jessamine.T for gore maybe?)
