From publisher blurb:
Thrilling Powers offers you lots of inspiration for your next campaign of Worlds in Peril. This supplement features dozens of pre-made powers for you to use as presented or to tweak to your own preference. Following the powers section there's a team of four pre-generated heroes, each with a fully-fleshed nemesis as well as an arch-villain to defeat.
A time travel-themed campaign outline gives you, the EiC, a place to start with a group of new players. This book is designed to provide enough inspiration for you to take the story in whichever direction you desire!
Thanks to the intuitive nature of the powers from Worlds in Peril, GMs of virtually any game system can use this book for their own supers game.
