Ug the Unreliable was an infamous goblin con artist who organised the Demiguise Derby and then made off with the profits.  At some point in his life he peddled Leprechaun gold, which lead to him being tracked down, and then imprisoned. His imprisonment might have provoked one of the Goblin Rebellions of the seventeenth or eighteenth century.  He is featured on a Chocolate Frog Card.
