In the TimeMaster, you play an agent of the Time Corps, dedicated to preserving history as it originally occurred. Unfortunately, time keeps changing, due to the blundering of Time Renegades who travel time to live where, when, and how they want and due to the influence of the alien shape-changing Demoreans, who wish to shape all time parallels to their own hideous concept of perfection. Your main tools: a chronoscooter, a "dink" ring, and your own Paranormal Memory of the way things should be. TimeMaster combines the excitement of traditional roleplaying, the problem-solving of a good mystery, and the educational value of public television.
