Pawns: The Opening Move (1992)

From the back cover:

Even in divine games of chess, the action begins with a clash of pawns. In Pawns: The Opening Move, the first supporting product for The Primal Order, you will find a collection of powerful minions, monsters, and other entities waiting to help you add some extra excitement and challenge to your game world. Whether you're searching for divine servants to intercede between your PCs and their distant deities, mighty beasts to defy even your strongest party, or just a few fascinating creatures for your adventurers to glimpse and wonder about, you need look no further.
