The Vacuous Grimoire Volume Three

From publisher blurb: Rules for Fantastic Creatures! This bestiary utilizes "modern" accouterments of The World's Most Popular Role Playing Game with an idea to recapture a sense of how the older version of the game rolled from the late 1970s West Coast, San Francisco Bay Area. Along with Volumes One and Two, these new works combine various home brew rules with the Open Gaming License "System Reference Document" into a single system. While this volume does contain some of the more common fantasy creatures, also found inside are foes and accoutrements from a darker and more deadly multiverse along with a bit of modern and science-fantasy.
