From the description: An unofficial Space Age supplement for the Other world's favourite fantasy role-playing game! Within its pages you'll find: The Other galaxy’s favourite space-age roleplaying game. Inspired by, and designed for use with, the innovative TROIKA! Ruleset. Interorbular adventure! 5 brand-new backgrounds, including rubberworld escapees, calculating cabooses, and the OBVIOUS protagonist. Keep the Other world clean. Inspired by the zaniest comedies across time and space, and printed on 100% recycled pulp. I can't believe it's not magic! We used sufficiently advanced technology to formulate 5 imitation spells almost indistinguishable from the real thing!
