Back cover blurb Rory's Drift is a Traveller one-shot scenario for 1-5 players. Designed to be played in a single session, the PCs find themselves recalled to duty by the Scouting service. It's time to go back to the Kellin system that was recently returned to the Imperium after the Aslan invasion. The party are reactivated by the Scouting service to make a preliminary investigation of the Scout base in Kellin. With a rogue group of Aslan unwilling to leave, pirates operating in the system, and the Imperium administration trying to execute a cover-up, things will not be straight forward for our intrepid party.
