Goblins are earth spirits.

Popular in European folklore, goblins are said to be knee-high, with heavy gray hair and beards.

They inhabit the homes of humans, where they indulge in poltergeist activities.

They are not fond of adults but do seem to like children, as they have been known to protect them and bring them gifts.
