In 1981, TSR released its second “Tome of Creatures Malevolent and Benign.” Edited by Don Turnbull, Managing Director of TSR UK, this folio full of fiends had a significantly different feel than TSR’s first manual full of monsters. F&F poses the question, what if this collection of creatures was not the second, but the first? How different would FRPGs be and the worlds that they implied?
The result is quite different from what one might expect from an FRPG. Gone are the world elves, dwarves and halflings. In their place is a world, not from some mythical past, but from an apocalyptic world of the distant future where The Sons of Cyn, Fiends of Entropy and Beastmen battle each other over what remains of a Civilization long in decline. This is due to the fact that the monsters presented could comfortably be found in the pages of science fiction stories as they could in pure fantasy.
Thus, this game is unapologetically science-fantasy and both players and referees are strongly encouraged to see magic and magic items not just from the lens of fantasy and the arcane, but as various strange sciences and technologies from a distant future.
