Dear UncleSam,
You are John Edward Gammel.
You were the cop assigned to Leonard Shelby’s case when two men broke into his house, raped his wife and smashed his head against a mirror, causing him to develop anterograde amnesia. Though Leonard shot one of the invaders, you, sympathetic to his quest for revenge against the second man (known only as “John G”), helped him track down the man and kill him…but he didn’t remember it. So, ever since you have been appearing and disappearing (almost like a ghost, which happens to be invisible, HEH) in Leonard’s life, leaving false clues framing others for the crime in order to satiate Leonard’s unending desire for vengeance, and to make a few bucks on the side.
At night you may PM askaninjask and Daenym “NX - Investigating <user>.” You will utilize your police connections to track down everyone who has targeted <user> during previous nights, and will also uncover what each perpetrator was targeting <user> with. You may investigate dead users.
<Snip>
You are allied with the Invisibles. You win if the Invisibles outlast the Assassins, the Alchemist, and the Stalinist Coalition for a Better Tomorrow.
