The H.P. Lovecraft Wiki

This subject contains information from the "Lovecraft Circle" Myth Cycles, and while guided by HPL are not based on his work alone. The Star Vampire, also known as the Shambler from the Stars, first appeared in 1935 within the Weird Tales pulp magazine in the Robert Bloch short story "The Shambler from the Stars".


Star Vampires are creatures from outer space that are normally invisible. They are voracious blood suckers, becoming visible once their bodies are full of the victim's blood, a vivid red colour. Its form is like that of a jellyfish with neither a head or any visible facial features apart from its huge maw. Their bodies have multiple muscular tentacles, each strong enough to crush a man to death and on the tips are the suckers with which it drains the blood of its victims. From the star vampires comes nonstop eerie horrifying laughter.

It's possible that the Star Vampires might be in some way related to Tsathoggua, since the infamous grimoire De Vermis Mysteriis contains a spell to summon them which mentions "bufoniformis Sadoquae" (i.e. toad-like Tsathoggua). The book's author, Ludvig Prinn, was known to keep a number of Star Vampires as his loyal servants. (CIRCLE: "The Shambler from the Stars")
