Within this top-secret dossier, you'll find a dozen otherworldly foes both bizarre and familiar, from the asteroid-dwelling sarcesians who ride solar winds on wings of light to technomagical undead horrors capable of ruling forever as the sinister Bone Sages of Eox. While all the creatures in this book are designed for use with Starfinder, all can be easily converted for use with Pathfinder, so there's no need to wait until August to start battling invaders from space!
