->''Eric is the Discworld's only demonology hacker. Pity he's not very good at it. All he wants is three wishes granted. Nothing fancy - to be immortal, rule the world, have the most beautiful woman in the world fall madly in love with him, the usual stuff. But instead of a tractable demon, he calls up Rincewind, probably the most incompetent wizard in the universe, and the extremely intractable and hostile form of 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 (quite fervently) again - this time that he'd never been born.''

Sometimes counted as the ninth ''Literature/{{Discworld}}'' novel, although this is where numbering gets tricky as some prefer to count ''[[strike:Faust]] 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 wasn't all that fond of writing, 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:

* AccidentalHero: Eric had intended to summon a demon to grant his every wish. He ends up rescuing Rincewind from the Dungeon Dimensions instead.
* AliensNeverInventedTheWheel: Human example: the Tezumen can make wheels, they just never figured out how to ''use'' them. People wear them as hats, and complain that they don't roll when you lay them flat and give them a push.
* BadassFingersnap: How Rincewind appears to grant wishes, to his own immense astonishment. [[spoiler: It's just Vassanego using ''his'' demon powers in synch with Rincewind's finger-snapping.]]
* BaitAndSwitchComparison: When an attempt to travel to Ankh-Morpork by magic lands Rincewind and Eric at the gates of Hell, Rincewind notes that he can tell this isn't Ankh-Morpork by such subtle clues as the distant screaming -- in Ankh-Morpork the screaming is usually much closer.
* 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 Eleanor 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]].
* [[BigLittleMan Big Little God]]: Quetzovercoatl has only appeared to the Tezumen priests in dreams, based on which they'd carved a giant statue of their demonic patron. When he actually has to ''manifest'', it turns out he's six inches tall.
* BilingualBonus: Lavaeolus' name is CanisLatinicus for "Rinser of Winds".
* BrickJoke: Rincewind still can't remember how to pronounce 'eon'.
* ChekhovsGunman: [[spoiler:Near the beginning of the book, it's mentioned that a demon named Vassenego was standing by to be summoned by Eric, but happened to be distracted at the crucial moment, so the summoning somehow latched on to Rincewind instead. Vassenego turns up again near the end, and it's revealed that in fact he went to considerable deliberate effort to divert the summoning to Rincewind, and has been masterminding the whole thing to distract Astfgl while he arranges a coup.]]
* 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".
** Rincewind and Eric find themselves in the middle of the Tsortean (= Trojan) War, which the Ephebians and Tsorteans in ''Discworld/{{Pyramids}}'' are still rather sore about ... even though neither side seems to remember ''which'' side did what, anymore.
* 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 bacterial life on the Disc was given a kick-start by Rincewind (who had gone back in time) tossing away the Egg-and-Cress sandwich given to him by The Creator.
* DeadAllAlong: Baffled by his apparent new-found demon powers, Rincewind speculates that he might have died in the Dungeon Dimensions and been sent to Hell as one. Considering how terrified, and how busy running, he'd been during his sojourn among the Dungeon Things, he supposes he might not have noticed the difference. [[spoiler: He's wrong, his "magic" finger-snaps are Vassenego's doing.]]
* 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.
* EpiphanicPrison: Of a sort. The demons traditionally inflict all sorts of physical torture on the souls of the dead, but as soon as they realize they have no actual physical body to be tortured, they stop feeling any pain and the whole thing goes on mostly out of habit.
* EternalRecurrence: Death watches the final end of the universe and is about to hang up his scythe when he notices matter spontaneously popping into existence and has a HereWeGoAgain realization.
* 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.)
** They also consider [[spoiler: Vassengo's]] [[KickedUpstairs scheme to get rid of him]] a bit much, and are amazed that humans came up with something like that on their own without any "hints" from them.
** 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.
* ExpectingSomeoneTaller: Eric, the demonologist who summoned Rincewind back to the material world and proceeds to order him around, turns out to be a thirteen-year-old boy.
* 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.
* FeatheredSerpent: Quezovercoatl is depicted as a feathered boa, [[spoiler:he actually looks nothing like that]].
* ForHalloweenIAmGoingAsMyself: Inverted by Astfgl, who dresses in royal diabolic regalia of his own design ... which is, basically, a kid's cheap Halloween devil-costume, complete with silly hood-mounted hornlets and a trident that keeps falling apart.
* 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.
* LiteralMetaphor: While climbing out from hell, Rincewind notices the stairs are made of stone letters spelling common well meaning justifications for actions with undesirable results. He figures out that te road to hell really is paved of good intentions.
* {{Mayincatec}}: The Tezumen.
* MindRape: The sheer unmitigated ''boredom'' of Hell under Astfgl's administration is so very abusive to the psyche that even Rincewind, who normally craves being bored as an alternative to his usual terrifying ordeals, is repelled by the place.
* 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.
* {{Parody}}: As well as the titular parody of ''Literature/{{Faust}}'', the sequence in Tsort mercilessly sends up UsefulNotes/TheTrojanWar.
* PlaceBeyondTime: Gods and demons exist outside of time, and Astfgl travels to the heat death of the universe and back without too much difficulty. It's mentioned that in theory this should make them omniscient, but the universe is so huge and complicated that it's simpler for them to just pick a starting point and watch from there.
* 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.
-->It would be a lazy use of language to say that the thing that answered the door was a nightmare. Nightmares are usually rather daft things and it's very hard to explain to a listener what was so dreadful about your socks coming alive or giant carrots jumping out of hedgerows. This thing was the kind of terrifying thing that could only be created by someone sitting down and thinking horrible thoughts very clearly.
* SelfInflictedHell: It turns out that this is the literal case on the disc. ''Only'' those who deep down believe they deserve hell end up in it, people who don't believe or know about it are safe. Which is why the narrator suggessts shooting missionarys on sight.
** Another instance is the demons inflicting the newly designed tortures. Since they consist mostly in inflicting inhumane ammounts of boredom, and the demons have to be there to inflict them, it's just as bad for them as for the victims.
* 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.
* SurprisinglyHappyEnding: Absolutely every single character gets their happy ending, this includes the demon king that gets effectively dethroned and imprisoned and, most surprising of all, the souls in the eternal torture of hell.-
* ThreatBackfire: Breaking into the Tsortean citadel via a secret passageway, Laveolus at once recites a prepared speech demanding the enemy's unconditional surrender. As the only person in the room is a small child on a potty, his well-rehearsed demand rather falls flat.
* 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.
* WorldsMostBeautifulWoman: Elenor of Tsort. Eric wishes to meet her, and [[spoiler: he does, but she's well past her prime, married, and the mother of several small children]].
* 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."
