Can even the Legion of Super-Heroes overcome the combined forces of Pulsar Stargrave, Quicksand, and Holdur? And what possible role can the Time Trapper play?

MAD ROOK'S GAMBIT can be played as the third in the four-part Chessman series, following PAWNS OF TIME and KNIGHT TO PLANET 3, in collaboration with the Legion of Super-Heroes Sourcebooks I and II, or as an independent adventure.
