Welcome.
You are a member of the Town Council of Anytown, a small close-knit town in the heartland of some country. Which town - heck, which country - isn't really all that important.
A woman stands before all of you. She is wearing a dark blue dress with an entirely white rose in the center. You notice that she is unnaturally beautiful. How'd that happen?
"Hey, guys.
"There is a horrible, dire threat facing this town.
"I have received word that this very 7-person council has been infiltrated by 2 stereotypical mafiosos, who have decided, for some reason, that it would be a really good idea to kill all of the rest of you. You're going to have to start killing each other - some might even say "lynching" - and hope you get them before they get you.
"Their motives aren't really clear to me. It's almost like they were playing a game or something.
"Anyhow, they don't plan to kill anyone in the middle of the night -- don't worry about that stuff. In fact, it's almost as if the night won't even take place.
"However! In exchange for this, beginning tomorrow and every other day, you'll have to lynch one person off a three-person list they choose.
"I hope this makes sense. Save the town! I wish you the best of luck, and URKKKK----"
You all take a look at her -- quite dead. How unfortunate. Looks like the seven of you are going to have to go it alone here.
