Kobold

The Kobold is a form of household spirit from Germany and Switzerland. They test the house and its occupants early on. It carries a pouch containing dust and dirt and will sprinkle some in the family’s milk. If this goes unnoticed, then the Kobold decides it is welcome in the home. They settle in the house, often under the stove. They assist when cleaning if not being watched and keep other spirits from the house. They move on only after the last of the family dies. If any servants were employed at the house, they would have to be taught how to not anger the Kobold, or suffer bad luck as a consequence.
