Hideous Creatures: Star Vampires (2014)

From publisher blurb:

In this series, Kenneth Hite looks at the creatures, species, and monsters of the Cthulhu Mythos from every non-Euclidean angle. Alternate versions and new explanations provide the same jolt of mythic bisociation that the gods and titans receive in the TRAIL OF CTHULHU corebook. Hite traces these foul things through their legendary history, and provides further clues for any Investigator to follow. Horrific scenario seeds burst and bloom, story spines protrude and deform, in a blasphemous garden any Keeper can harvest.

“The human blood on which it had fed revealed the hitherto invisible outlines of the feaster.” Invisible outlines that shall be expanded upon, extended even, into all sorts of dimensions. Are they summoned demons or feral predators? Are they kindred or competitors to Colin Wilson’s Space Vampires? Herein we trace the Shambler From the Stars, with bonus Night’s Black Agents statistics and a scenario seed.

Hideous Creatures: Star Vampires is the eleventh installment of the Ken Writes About Stuff subscription, or it’s available as a stand-alone product.
