Goblins are a product of European myth. They are members of the Orc family.
Many people confuse goblins with demons.
This is inaccurate. Goblins are said to be somewhat like Orcs in appearance, with gray to green shiny, slippery skin. They are small er that Orcs, elves, and gnomes, with large pointed ears. Like orcs, elves and gnomes, they are said to be miners who spend most of their time underground. They are referred to as being unliked by the other little people which is the reason for their ill tempered, antisocial behavior.
