A goblin is a legendary evil or mischievous grotesque dwarf-like Demon or monster that appeared in European stories and accounts during the Middle Ages.
They are ascribed various (sometimes conflicting) abilities, temperaments and appearances depending on the story and country of origin.
In some cases, goblins are little creatures related to the brownie and gnome.
Goblins are mischievous malicious fairies that live in small caves and underground caverns. Sometimes goblins attach themselves to houses or families – they can be heard at night, banging pots and pans, dragging furniture around, rapping at doors and windows, or even snatching the bedclothes off sleeping people.
Sometimes goblins help parents in disciplining their children: they give presents to children who have been good, and punish and play wicked tricks on those who have been naughty.
They are usually small, sometimes only a few inches tall, sometimes the size of a dwarf, and have magical abilities; they are greedy, especially for gold and jewelry.
