Goblins are small, grotesque, and malevolent creatures. They are knee-high to men and have thick grey hair and beards. They prefer to live in human homes, and act like Poltergeists, causing much trouble and making a general nuisance of themselves. Unlike Poltergeists, however, they will protect and give gifts to children. Goblins generally dislike adults.
Goblins often have misshapen features, though they are generally human-looking. When they talk it is said to sound like dust travelling through cracks in the rocks or like mud being squished under a rock. Goblins are generally not very bright, but they are excellend thieves.
