Generate a Complete One-Shot Tabletop RPG Adventure

It's Thursday, four people are coming round Saturday, and you're meant to be the Game Master. Pick a genre and a central conflict and it writes a self-contained one-shot: premise, a small cast of memorable NPCs, three to four hours of play, a twist, and a clean ending. Minimal prep on your side.

A one-shot tabletop RPG adventure must be self-contained: it has a clear premise, enough material for three to four hours of play, a satisfying resolution, and minimal preparation burden for the Game Master. Great one-shots have a simple central conflict, a small cast of memorable NPCs, and at least one unexpected twist.
