From publisher blurb: Xenopedia is a bestiary and adversary collection for science fiction adventures and campaigns powered by the Entropic Gaming System. Although Xenopedia is designed to be used with Entropic Heroes: Science Fiction, it’s completely universal and is usable with any science fiction setting or campaign, published or homebrewed. Each xeno entry provides a background of the species, the basic stat block, general motivations, and even a scattering of NPCs, minions, or alternate stat blocks. With all entries powered by the OGL, Third Party Publishers can use them too! Xenopedia includes: 35 different xenos species including… Intelligent species. Non-organic species. Animal-like species. Monstrous species. … and more! A keyword rating system to better understand the species. Villains. Illustrations of each species.
