Hellspawn Flutterer

Source: Harker's Guide to Vampire Hunting

When a fiendish spirit is pulled out of Hell and forcibly bound into the corporeal form of a corpse, the ensuing result is a hellspawn, a creature of hideous proportions that resembles a humanoid with monstrous characteristics. No two hellspawn are exactly the same, but they can broadly be sorted into different categories based on their outward appearance and function. Typically, hellspawn are created by hellcrafters, occult magic users that specialize in the creation of these creatures.
