The party is group of retired adventurers who manage a tavern, they have to make it through while keeping their tavern running, and the town in one piece.
The party shouldn't be magic heavy or muscle heavy. And hopefully have at least a good CHA based character. No other requirements.
This can be inserted in any world with a sufficiently big and rowdy town or city. But by default it uses my own, The Floating Lands, a short excerpt about it is included.
