Vuay's Game

From Introduction: The characters are patrolling the border to Gra’bov space when a being of apparently unlimited power arrives and tells them that it is setting up a game between them and the Gra’bovs. The winner gains access to an extremely powerful weapon. If the crew refuses to play the game, they forfeit… and they die. This is an adventure meant to be run with little weaponry, but a lot of craft, wit, and daring.
