Concept: That scene in every 90s high school movie where someone shows the new kid around the cafeteria (”that table is the nerds, those are the jocks, the goths, the cheerleeders” etc) except it’s a medieval tavern and each table has a different d&d class.
“Look, newbie, where you sit in the tavern is crucial because you got everybody there. You got your NPCs, Rangers, Sorcerers, Warriors, Warlocks, Druids, Barbarians, Monks, the Greatest People You Will Ever Meet (Bards) and The Worst: beware of the Paladins.”
