This book is a supplement for Qalidar: Resistance. It has lots of monsters. Some of them were in previous Qalidar books and some of them are new. You need the Qalidar: Resistance RPG Basic Book to use them, unless you just want to look at the pictures. The Qalidar: Resistance RPG is based on a streamlined set of d20-based rules for a quick start and fast action in play.
