Eric
by Terry Pratchett
The story is a parody of the tale of Faust, and follows the events of Sourcery in which the Wizard Rincewind was trapped in the Dungeon Dimensions. The Discworld version of Hell or Pandemonium exists simply because some people believe that it exists for them. In other Discworld stories, such as Small Gods, the afterlife is different or non-existent, according to the various beliefs.
Rincewind wakes in a strange place, having been summoned to a house in Pseudopolis by the 13-year-old demonologist, Eric Thursley, who wants the mastery of all kingdoms, to meet the most beautiful woman who ever existed, and to live forever. He is disappointed when Rincewind tells him he is unable to deliver any of these things, and embarrassed when Rincewind sees through his disguise. Rincewind is disheartened to learn that the spells to confine the demon summoned are working on him; Eric's parrot tells him that because he was summoned as a demon, he is subject to the same terms.
The arrival of Rincewind's Luggage causes Eric to suspect deceit on Rincewind's part. Eric's demands are renewed; he makes three wishes of Rincewind. Rincewind insists he cannot grant wishes with the snap of a finger, and discovers to his horror that snapping his fingers really does work.
* 'To be Ruler of the World'. Eric and Rincewind find themselves in the rain forests of Klatch, in the Tezumen empire, a parody of the Aztec Empire. The local people come forward to pay tribute to Eric and declare him Ruler of the World. During this tribute, Rincewind and the parrot explore the temple of Quezovercoatl (a parody of Quetzalcoatl), where they find a prisoner, Ponce da Quirm (a parody of atheist, "which still allowed them to kill anyone they wanted, but they didn't have to get up so early to do it".
They discover hell steeped in bureaucracy, the Demon King Astfgl having decided that boredom might be the ultimate form of torture. Rincewind uses his university experience to confuse the demons, so he and Eric can try to escape. While crossing through the recently reformed levels of hell (satirical forms of Dante's Inferno) they encounter da Quirm and the parrot, as well as Lavaeolus, who tells them where the exit is.
The source of Rincewind's demonic powers is revealed to be Lord Vassenego, a Demon Lord leading a secret revolt against Astfgl. Using Rincewind to keep Astfgl occupied while gathering support amongst the demons, Vassenego confronts his king just as Astfgl finally catches up to Rincewind and Eric. Vassenego announces the council of demons has made Astfgl "Supreme Life President of Hell", and that he is to plan out the course of action for demons. With Astfgl lost in the bureaucratic prison of his own making, Vassenego takes over as king and lets Rincewind and Eric escape, so that stories about hell can be told.
