Eric

Eric is the Discworld's only demonology hacker. Pity he's not very good at it. All Eric wants is his three wishes granted—to be immortal, to rule the world, and to have the most beautiful woman in the world fall madly in love with him. But he ends up with Rincewind, the most incompetent wizard in the universe, and his extremely intractable and hostile travel accessory, known as the Luggage. With them on his side, Eric's in for a ride through space and time that is bound to make him wish that he'd never been born.
