A vargouille is a hideous, disgusting, and vile creature that is little more than a severed head with bat wings. The creature is slightly larger than a human head with a foot-long wingspan. These creatures from the Abyss flap through the air in search of prey to infect with potent diseases that perpetuate their abominable kind. They delight in causing pain and live to bestow a demonic curse on their victims. Those so cursed develop demonic features, and soon die as their head rips itself away from their body and unfurls its own bat wings.
