You've taken over a tavern that's existed for centuries now, one whose every owner must agree to an accord: four nights in a month, the tavernkeep must play host to a group of extraordinary clientele. They always arrive at dusk, they don't give out their names freely, and they expect to be entertained.
Easy enough, right? Up until the party is crashed by your childhood best friend who can't ever learn the truth.
So, tavernkeep, keep the drinks flowing, do your best to keep your friend in the dark, and—most importantly—don't make deals lightly.
