From publisher blurb:
Terror from Beyond the Stars!
Mythos Monsters brings over 40 eldritch abominations from the dark places beyond the stars to your Black Flag Roleplaying campaign, with beautiful artwork for every one! Unleash the mind-bending majesty of the Lovecraft mythos on an unsuspecting world, with mythos minions like the deep ones, faceless stalkers, and the hideous hybrid blood of Yog-Sothoth and inhuman horrors like shantaks, gugs, nightgaunts, and the hounds of Tindalos, or terrifying titans like bholes, primal shoggoths, and flying polyps. Their unfathomable plots are guided by monstrous masters like the mi-go, elder things, and denizens of Leng, or even two of the Great Old Ones themselves in dread Cthulhu and Hastur the Unspeakable. Plus, you’ll find tools and templates to turn ordinary monsters into pseudonatural xenoid monstrosities, with options for epic variants!
