Sometimes counted as the ninth ''Literature/{{Discworld}}'' novel, although this is where numbering gets tricky as some prefer to count ''Eric'' as a special. It's shorter than most Discworld novels, was published by a different publisher, and was originally intended to be an illustrated work. The title is officially simply ''Eric'', but on most covers it is preceded by the struck-through title ''Faust'', a reference to how the title character is a [[TwiceToldTale parody]] of ''Theatre/DoctorFaustus''.

Rincewind was trapped in the Dungeon Dimensions at the end of ''{{Discworld/Sourcery}}'', but is now summoned back to the Disc by Eric, a young demonologist who was trying to summon a demon with a similar name. (For much of the book he's convinced Rincewind ''is'' a demon.) The story follows the two of them as they inadvertently travel through space and time to grant Eric's ThreeWishes.

Meanwhile, the King of Hell, the demon Astfgl, is trying to find them, but is always one step behind. His subordinates are mutinous thanks to his attempts to instil modern business practices in Hell--prior to his rule, the damned souls had worked out that pain was purely subjective and thus all the whippings and flayings were purely for the look of the thing, but Astfgl instituted project planning, health and safety and so on and now Hell torments both the damned and its own demons.

This was the last Discworld novel to feature Rincewind (a character whom Terry Pratchett somewhat dislikes, though the fans like him) until the retrospective ''Discworld/InterestingTimes''. It is also the last to feature the early conception of Unseen University, with the staff changing with each book thanks to the wizards' practice of KlingonPromotion.

Preceded by ''Discworld/GuardsGuards'', followed by ''Discworld/MovingPictures''. Preceded in the Rincewind series by ''Discworld/{{Sourcery}}'', followed by ''Discworld/InterestingTimes''.

Was adapted by Creator/TheBBC as a short radio play in 2013.

!! ''Eric'' ontains examples of:

* BatmanGambit: [[spoiler:Vassenego's plan against Astfgl.]]
* BeCarefulWhatYouWishFor: Eric's wishes are (1) to rule all the kingdoms of the world, (2) to meet the most beautiful woman ever, and (3) to live forever. He and Rincewind first visit the Tezumen Empire [[spoiler: who try to sacrifice him out of revenge for their absolutely abysmal living conditions]], then meet Helen of Tsort [[spoiler: about 20 years past her prime]], and finally get to live forever [[spoiler: starting from the Creation of the Discworld, meaning it will be quite a few millenia before any people show up]].
* BrickJoke: Rincewind still can't remember how to pronounce 'eon'.
* TheChessmaster: [[spoiler:Vassenego.]] Which is appropriate, as [[spoiler:he's a parody of Vassago, generally considered the wisest demon in Hell.]]
* ContinuityNod: The Creator briefly worries that he's forgotten something immediately after creating the Discworld. As revealed in ''Discworld/TheColourOfMagic'', he's left the ''[[TomeOfEldritchLore Octavo]]'' behind in "a characteristic bout of absent-mindedness".
* CoolAndUnusualPunishment: Astfgl's use of boredom as torture.
* CoolTank: Not spelled out, but at the end, Lavaeolus' soul in Hell has the idea for using one of the conveyor belt treadmills as the basis for a new war machine.
* CosmicEgg: It turns out that life was created by Rincewind (who had gone back in time) tossing away the Egg-and-Cress sandwich given to him by The Creator.
* DealWithTheDevil: Eric was shooting for one of these, but accidentally summoned Rincewind instead of the demon who was going to make a deal with him.
* DelegationRelay: Happens to a chain of soldiers trying to find someone to look after a lost child during the Tsortean War.
* DoorOfDoom: Hell has an impressive one, except the new regime adds a badly-installed doorbell and a jaunty sign.
* EarlyInstallmentWeirdness: Old Tom, Unseen University's bell, is stated to be made of bronze, and used to be normal until its clapper fell out, causing it to toll silences instead. Later books retcon it so that the quirk is a result of being made of the magical metal octiron.
* EvenEvilHasStandards: Most of the demons are unhappy because Astfgl found the ultimate torture weapon: [[spoiler:boredom.]] (This could just be because it affected them as well.)
** This has hints of a MythologyGag, considering it echoes Crowley's own attitude to being a demon. ''Literature/GoodOmens'' and ''Eric'' were published in the same year, which suggests that they were written at roughly the same time.
* FalseReassurance: Lavaeolus, an [[Literature/TheOdyssey Odysseus]] parody, asks Rincewind if he'll get home all right. Rincewind figures that YouCantFightFate and tells him yes, and they'll write stories about him getting home.
* FountainOfYouth: What Ponce da Quirm is searching for. In a typically Pratchett subversion, he actually finds it - but [[spoiler:his soul in Hell muses that someone should've told him 'boil the water first']].
* GoodOldWays
* HumansAreTheRealMonsters: Astfgl recommends learning from humans in order to inflict really horrible torment.
* IdenticalGrandson: In an extreme example, Rincewind's distant ancestor Lavaeolus bears a passing resemblance. He also shares Rincewind's keen survival instinct as well as, judging by his ten-year journey home, Rincewind's bad luck. Not to mention his name, [[BilingualBonus if you speak]] Latin... Er, Latatian.
* KickedUpstairs: [[spoiler: Astfgl]]'s final fate. Subverted in that he's quite happy there.
* TheKidWithTheRemoteControl: PlayedWith with Eric himself, whose attempt to summon a fearsome demon that will grant him his every desire lands him with the ineffectual and very human Rincewind instead.
* {{Mayincatec}}: The Tezumen.
* MindRape
* NamesToRunAwayFromReallyFast: Astfgl is just the first one.
* ObstructiveBureaucrat: and King of Hell.
* OneDimensionalThinking: Justified due to "sheer idiot terror" with the jaguar that gets eaten by the Luggage.
* PunnyName: Quetzovercoatl, a pun on the Aztec god Quetzalcoatl and 'overcoat'.
* RealDreamsAreWeirder: {{Discussed}} in the narration when describing the demon guarding the gates of hell.
* SelfInflictedHell
* ShoutOut: Astfgl's summary of Tezumen history paraphrases UsefulNotes/AbrahamLincoln's Emancipation Proclamation.
* TheStarscream: [[spoiler:Vassenego.]]
* TheStrategist: Lavaeolus, who uses his cowardice to help him develop plans with a low chance of getting him (or anyone else) killed.
* TooManyHalves: Quezovercoatl is described as "half-man, half-chicken, half-jaguar, half-serpent, half-scorpion and half-mad", making him three homicidal maniacs.
* TooManyMouths: Urglefloggah, although where they are isn't specified.
* TranquilFury: Astfgl provides a page quote.
* [[TrojanHorse Tsortean Horse]]: DoublySubverted. The Ephebians build a wooden horse and leave it outside the Tsortean city gates. The Tsorteans bring the horse inside their walls... Except they saw right through the ruse, and when night falls, they're wide awake and waiting outside the horse to ambush whoever comes out... ''Except'' the horse was only a distraction so that the Ephebians could sneak in a different way.
* UnderNewManagement: Hell has recently come under new management, so the traditional punishments get scrapped in favor of mind-numbing eternal boredom.
* TheUnpronounceable: Most demonic names are this. When Astfgl tries to look up Rincewind's name in the registry of demons, he notes that "Rincewind" has far more than the usual number of vowels in it.
* VerbalTic: Eric's parrot, who constantly substitutes the catchall metasyntactic variable "wossname" for random words, along with, to a lesser extent, "Polly want a biscuit," described in the narration as being in the same tone that a human would say "Err..."
* WeHaveReserves: The usual attitude of the Ephebian and Tsortean generals--Lavaeolus is considered a bit of a cheater because he actually tries to win battles without huge casualties.
* WhatHappenedToTheMouse: We don't see the pair actually emerge again on the Discworld after their foray into Hell, and only Rincewind appears in later books, so it's left unstated what became of Eric.
* ZergRush: "The consensus seemed to be that if really large numbers of men were sent to storm the mountain, then enough might survive the rocks to take the citadel. This is essentially the basis of all military thinking."
