[[quoteright:200:http://static.tvtropes.org/pmwiki/pub/images/DLODERK_1357.JPG]]
A Young Adult fantasy novel by Creator/DianaWynneJones, set in the world described in her meta-fictional book ''Literature/TheToughGuideToFantasyland''. Except Fantasy Land is not quite what you'd expect; it is not, in fact, a perpetually medieval world of black and white morality, but is instead ruled with an iron fist by Mr Chesney, a businessman who runs tours for very rich people from our world.

After years of oppression, the various rulers, high priests and wizards of the world get together to decide what to do, and visit the two oracles, where they learn that they must appoint the next two people they see as Dark Lord and Wizard Guide for the upcoming tour in order to be rid of Mr Chesney forever.

Unfortunately, though, the next two people they see are the Wizard Derk, who is middle-aged, friendly, and very good at what he does (which happens to be blending genetic engineering with magic to create hybrid animals), and his fourteen-year-old son, Blade.

Hijinks Ensue.

It has a sequel called ''Year of the Griffin'', which, in typical Wynne Jones style, is a little disconnected from the original. It follows one of Derk's [[SpinOffspring children]], Elda, as she attends university for the first time.

----
!!Tropes featured in both works include:

* AllWitchesHaveCats: Querida, the most powerful witch on the continent, owns three cats.
* BewareTheNiceOnes: Derk's children. Never get on the wrong side of a pissed off griffin.
* ColdIron: Iron is much harder to work magic on than other substances, and untrained wizards can't use magic while in contact with iron.
* DeliberatelyCuteChild: Elda knows that her fluffy golden feathers and kittenish demeanor are powerful weapons.
* DragonHoard: Dragons hoard gold because they need its nutrients, which they absorb by sleeping on nests of treasure.
* FantasticScience: Derk's forte.
* GadgeteerGenius: Callette is one of these... and she's a ''griffin.''
* GeniusBruiser: Kit
* MassiveNumberedSiblings: Seven in the first book, [[spoiler: nine in the second]].
* NiceToTheWaiter: Emperor Titus' kindness to animals marks him as a good guy early on.
* SufficientlyAnalyzedMagic
* TrademarkFavoriteFood: Elda loves fresh fruit--oranges especially.
* TrulySingleParent: Only two of Derk's seven children [[spoiler: nine in the sequel]] were born in the natural way. The others were created by him in his magical lab. However, he ''does'' use DNA from his wife in the other children, so they're still "related" to both their parents. This despite being ''griffins.''

!!Tropes featured in ''Dark Lord of Derkholm'' include:

* AmusingInjuries: Averted early in the book where Querida gets run over by Derk's animals. In what would likely be an Amusing Injuries situation in most works, they instead have her suffering multiple broken bones that lead to her being in a magical coma for a significant portion of the book. In contrast, when Reville gets trampled by horses later, he suffers nothing more than a few painful bruises.
* AttemptedRape: It's unclear how far it goes. [[spoiler: Shona is at the very least molested by an entire gang of soldiers. Scales magically helps her cope, but she can never entirely forget.]]
* TheAtoner: Querida, after she realizes that she has caused actual harm to Derk and his family.
* AutomatonHorses: averted with a vengeance.
* BadBadActing: One of the rulers must pretend, as part of the plot of the Tour, that he is secretly being mind-controlled by the Dark Lord. His interpretation of this involves walking around like a zombie and speaking all his lines in a monotone.
* TheBaroness: Querida is the Rosa Klebb type.
* BatmanGambit: ''Inverted,'' of all the crazy things. [[spoiler: Derk is genuinely clueless. However, everyone around him hopes his cluelessness will convince the odious fellow abusing their world to leave them alone, and so they try to help him be ''more'' clueless than usual. Naturally, this is the exact time Derk decides to get competent, and kicks the bad guy out by doing the ''exact opposite of what everyone thought he'd do.'']]
* BrainlessBeauty: Geoffrey's sister Sukey. [[spoiler: Or so it seems. She's actually just as shrewd as her brother; she plays the part well, though.]]
* CatsAreMagic: Dirk's cats, which he bred to be invisible, are also inexplicably unable to be trapped for long, they always find their way out, even from magical barriers.
* ChewToy: Derk. Oh, heavens, Derk. [[spoiler: his wife leaves him, his house is destroyed, his daughter nearly gets gang raped, his son gets shot and killed in front of him -- is it any wonder that he ends up having a nervous breakdown and hiding in a pigsty? And that was the ''plan''. The planners just weren't expecting him to be so competent...]]
* CueTheFlyingPigs: An elf king hopes [[CorruptCorporateExecutive Mr. Chesney]] will eventually free his son. His other son says "Yea, and that day will come when pigs do fly." Sarcastic, yes, but a prophecy is a prophecy. As it happens, the protagonist, Derk, breeds flying pigs...
* CloudCuckoolander: Derk. He's incredibly brilliant and so awkward, clueless, and spacy, everyone expects him to fail spectacularly as Dark Lord.
* CoolHorse: Beauty and her foal Pretty, Derk's winged horses, are so cool that the elf Prince is willing to pay a year of servitude for.
* CreatingLifeIsAwesome: The titular wizard creates new life forms all the time, including griffins and winged humans. Some of them contain his own DNA and are treated as family members. Although this creates some unusual parent-child tensions, his creative work is treated as a positive thing on the whole.
** This story also subverts CreatingLifeIsBad, by having various characters wrongly believe the protagonist to be evil.
* DeathGlare: Querida has one.
* DisneyVillainDeath: Derk runs out of interesting ways to die and resorts to just making an evil speech while waiting for the tourists to realize that he's been standing directly in front of a bottomless pit the entire time.
* DungeonMaintenance: On a far greater scale than usual.
* EvilVizier: It's ''very'' subtle, but it's implied the Grand Vizier of the Emirate acts this role for the Tours.
* FamilyUnfriendlyDeath: ''Barnabas''. Dear Lord, Barnabas.
* FiveManBand: Derk's seven children in the original:
** TheLeader: Kit.
** TheLancer: Shona to Blade, Blade (frequently the POV character) to Kit, the two humans.
** TheBigGuy: Don and later, [[spoiler: Lydda]] (who was actually created by Derk to be surprisingly tough).
** TheSmartGuy: Callette. Shona can sometimes function in this role as well.
** TheChick: Lydda and Blade.
** TagalongKid: Elda.
* FriendToAllLivingThings: Derk.
* GeniusBruiser: Scales
* HeroicBSOD: Derk after [[spoiler: he believes Kit is dead]].
* InstantAwesomeJustAddDragons: Scales.
* KillerRabbit: Derk's flock of sheep was accidentally bred to be carnivorous, and is frightening enough to keep hardened criminals in line.
* KingIncognito: [[spoiler:Scales]] is actually [[spoiler: Deucalion, king of the dragons.]]
* KnightTemplar: Querida's only priority is to rid the world of Mr. Chesney. [[spoiler: The gods acknowledge her basic intentions by giving her the task of ''finishing'' the job.]]
* LoveAtFirstSight: Geoffrey and Shona.
* MedievalStasis: Subverted. While the denizens of Derk's world have to make their world ''look'' permanently medieval for the tourists, they actually have many kinds of technology. Some houses in the nearby village have electricity, to Mr. Chesney's chagrin.
** Also, modern technology is being smuggled in--Derk's children think their new GameBoys are amazing.
* MessyPig
* MrViceGuy: Querida. She is one of the good guys, but some of her actions--like trying to kidnap Callette for a pet, and her abusive attitude toward Derk, make her downright despicable at times.
* MyGodWhatHaveIDone: Querida, on realizing what she's done to Derk's family.
* OffingTheOffspring: Chesney to his step-son.
* OurDragonsAreDifferent: Although they, too, have to pretend to be the same for the sake of the tourists.
** Turns out, the real reason dragons hoard gold is because [[spoiler:they get "vital vitamins" from sitting on it.]]
* [[OurElvesAreBetter Our Elves Aren't That Bad]]: The most prominent elf character is a ProudWarriorRaceGuy, and quite decent. The rest probably the same, but they don't get as much attention as he does. They do make you feel like you suck after they leave, but they don't actually ''say'' anything about it -- it just seems to come naturally to them.
** Dragons pick up much of the slack in the holier-and-wiser-than-thou department, an aloof attitude which Scales (who has claim to being a wiser dragon than any of them) both lampshades and criticizes.
* OurMermaidsAreDifferent: Throughout the book, the hero, Derk, attempts to figure out what to make his next project. He spends a lot of it mulling over making mermaids [[spoiler: in the hopes that collaborating to carry and raise a mermaid child will help bring him and his wife closer together.]]
* ObfuscatingStupidity: [[spoiler: Think Sukey is just a BrainlessBeauty? Think again.]]
** In fact, [[spoiler:most of Blade's tour group is working for some government agency or another.]]
* ParentsAsPeople
* ProudWarriorRaceGuy: Elf Prince Talithan, and Scales. Talithan is at one point highly upset because the city [[DesignatedVillain he was going to sack]] [[spoiler: didn't have any people in it]].
* PunchClockVillain: Derk is perhaps the ultimate example. He isn't even ''evil.'' He ''has'' to play the Dark Lord because his boss sucks.
* TheGenericGuy: Don, who is, for the most part, normal.
* StarSpangledSpandex: Derk's original cape as Dark Lord has a lining made of a miniature universe.
* {{Stripperiffic}}: Some of Mara's Glamorous Enchantress costumes.
* SupremeChef: Lydda is the only griffin who really likes cooked food--in fact, she's a ''master'' of it.
** Mmm... godlike snacks.
* UpliftedAnimal: Derk's specialty.
** SapientSteed / TalkingAnimal: The winged horses (although the first generation has a bit of trouble with vowels).
** AscendedToCarnivorism: The carnivorous sheep.
* TwoLinesNoWaiting: The later half of the book ping-pongs between the adventures of Derk and those of his children, Blade, Shona, and Kit, as they lead a party through the "game."
* UglyGuyHotWife: Everyone wonders how Derk managed to score a babe like Mara.
* WingedHumanoid: [[spoiler: What Derk decides to make at the end of the book. We see these two children in the sequel.]]
* AYearAndADay

!!Tropes featured in ''Year of the Griffin'' include:

* {{Adorkable}}: Pretty much all of Elda's male friends in the sequel are rather endearingly awkward. Lukin is probably the ''most'' confident (it's hard to say whether Ruskin's is this or bravado), but Felim is the most obviously awkward-sweet. Not to mention Derk himself.
** [=Flurian Atreck/Flury=] in spades. Elda hates it because she's used to Kit's overbearing attitude.
* AscendedExtra: Corkoran in the sequel. One-off in the original book; main teacher in the sequel.
* [[spoiler: AssassinOutclassin: The seven assassins sent by the Emir of Ampersand fail resoundingly to kill Felim, thanks to the extensive protective spells and even more extensive traps that he and his friends set up before they got there.]]
* BalefulPolymorph
* BigDamnHeroes: [[spoiler: Kit and Blade running off the primal griffins from Callette and Elda.]]
* BigBrotherInstinct: Titus to Claudia. He adores her, and threatening her well-being is pretty much the only way make him really, truly mad. [[spoiler: When he learns that the Senate has plotted to murder her, he throws the lot of them in jail, declares martial law, and rushes off to make sure she's all right.]]
* BrainlessBeauty: Nicely subverted with Melissa.
* CainAndAbel: [[spoiler: The Emir, who has sent assassins to kill Felim, turns out to be his older brother.]] The strange thing is that, while they seem to spend a lot of time yelling at each other, they're actually fond of each other; [[spoiler: The Emir actually wants Felim to be his heir,]] he just felt honor-bound to go through with the threats he made in a moment of rage.
* CallingTheOldManOut: Happens all through the book...as the students' tuition letters reach their homes. Olga has the most notable example.
* CoolAndUnusualPunishment: The spells that Elda and her friends inflict on the would-be assassins are quite... unusual. They involve turning them into roosters, ash, and... making them drown in pits full of orange juice.
* [[CoolVersusAwesome Pirates vs Ninjas]]: When Olga's father and his crew (pirates) encounter the Ampersandian assassins (ninjas). They team up.
* DemotedToExtra: Don, the most normal and least quirky of Derk's griffin children, hardly appears in this book, on account of spending most of it on another continent.
* FreudianExcuse: For Corkoran. He was kicked out of his home at age fifteen, and the University is the only home he has.
* HonorBeforeReason: Felim has a mild case of this- he often feels compelled to do things by his honor, but his friends talk him into sensible behavior when necessary.
* LoveAtFirstSight: Rather a ''lot'' of it, with [[spoiler:Lydda and her new husband, Blade and Claudia, Titus and Isodel, seemingly Lukin and Olga, and Flury and Elda.]]
* MixedAncestry: Claudia has such a background, and she suffers for it rather a lot.
* MouseTrap: After Elda turns the pirates into mice, every student in the school gets busy trying to design one.
* MustHaveCaffeine: Olga. She gets everyone else addicted to coffee too, as befits a bunch of college students.
* NoKillLikeOverkill: Elda and her friends engage in ''defensive'' overkill to protect [[spoiler: Felim from assassins]].
* TheNondescript: Flury goes to some trouble to be this way.
* ObfuscatingStupidity: Flury doesn't go out of his way to show it but he's actually one of the strongest wizards in the world.
* OffscreenMomentOfAwesome: Kit and Blade have been busy adventuring in the meanwhile. Aside from a brief mention of serving in the war, this is not brought up at all.
* OurFounder: Subverted. [[spoiler: The statue of the wizard Policant actually turns out to ''be'' Policant, who apparently turned himself into a statue as part of a prophecy, to be revived in the titular Year of the Griffin.]]
* OurDwarvesAreAllTheSame: Despite his full beard, the dwarf is about twelve years old (in human terms; he's actually thirty-something) and embarrassingly pubescent.
* ParentExMachina: not literally; but the return of Querida and the older wizards to the University plays with this.
* PromotionToParent: This is the backstory of Lukin; it caused him great frustration when his father came back and tried to treat him like a child again.
* PutOnABus: Shona, although Elda does mention her towards the beginning.
* SixStudentClique: The students.
** The Head: Lukin
** The Muscle: Ruskin
** The Quirk: Felim
** The Pretty One: Olga
** The Smart One: Claudia
** The Wild One: Elda (Though Elda is TheHero, in the story)
* SiblingTeam: Kit and Blade work as one.
* SoBeautifulItsACurse: In the sequel, everyone is surprised when seeming BrainlessBeauty Melissa sticks up for Olga against [[spoiler: her horrifying misogynist father]]. She brings up how everyone thinks that just because she's pretty, she can't be a good wizard.
* SpellBook: The six students' main way of learning magic, since so many of their tutors are incompetent.
* StealthPun: The Emir's kingdom, Ampersand.
* TwoTeacherSchool: Not quite, but almost. There are about five teachers mentioned, but only two of them seem to have a role in teaching the six main characters- Corkoran (their tutor, who also gives lectures to them) and Wermacht (who teaches almost all the first-year classes). Neither is terribly competent. (One character mentions attending Myrna's lectures as well, but this comes up only once.)
** This is actually something of a plot point. When Chesney's reign ended all of the senior wizards took the opportunity to retire, leaving the school with a SkeletonGovernment.
* VolleyingInsults: In marked contrast to his behavior in the rest of the book, Felim engages in this with [[spoiler: his brother the Emir.]]
* WriterOnBoard: [[spoiler: Olga's horribly misogynistic father, and the backlash against him.]] However, while it does make a very clear point about sexism, it ''does'' also help build sympathy for Olga.
