From the back of the book:
Here they are, up from the slime and in from the dark, ready to make life in your campaign just a little bit more uncertain! SCORPION MEN AND BROOS is a collection of 45 Scorpion Men and 54 Broos, all different and all pre-rolled by computer program (right down to the hit locations). Meet 'em in groups or singly, or run a quest right through a Scorpion Men Nest!
Individual background notes on both Scorpion Men and Broos, including advice to Referees on their game deployment, by Greg Stafford.
Campaigners will save hours of preparation: the 99 crafty creatures summarized within provide material for dozens of adventures!
SCORPION MEN AND BROOS is based entirely upon the role-playing game RUNEQUEST! You must have that rulebook to use these characters.
