Hödekin - Always wearing felt hats that obscure their faces, these German faeries are related to brownies, and guard households viciously, sometimes even shapeshifting into monstrous forms to frighten away intruders. They are usually compliant and happy to serve the human residents of their habitats, and are known to keep watch overnight and warn people of problems and toils in the future. When they are angered, they will rapidly become murderous and excessively violent, and must be exorcised.
