KOBOLD

[Folklore] In German (Teutonic) folklore, kobolds are spirits who dwell in mines and who like to torment humans. They are tricksters and not inherently evil. Like Robin Goodfellow, they may either help or harass humans, for unknown reasons. In the 16th and the 17th century, they were usually depicted on paintings as little devils with a conical hat, pointy shoes, a hairy tail, and bald feet instead of hands. In the class of fairy-like beings, they are considered to be the most dangerous and most ugly. Some sources suggest that kobolds are related to the Brownies
