The Draco Trilogy was an epic ''Franchise/HarryPotter'' FanFic series written by the BigNameFan [[Creator/CassandraClare Cassandra Claire]].[[note]]Yes, ''her'', now a published author of the ''Literature/TheMortalInstruments'' series. She now spells her name Cassandra ''Clare'', [[SpellMyNameWithAnS without an I]]. It's a pen name; she can do that.[[/note]] It used many of the same tropes found in ''The Mortal Instruments'', and deviated wildly from Harry Potter {{canon}} because it was begun before the fifth book was released. The series consisted of three novel-length fanfics: ''Draco Dormiens'', ''Draco Sinister'' and ''Draco Veritas''. It began with a standard FreakyFridayFlip plot and developed into a complicated tale involving all sorts of magical inheritance, the four founders of Hogwarts and more.

Notable for beginning the DracoInLeatherPants phenomenon, the story took Harry's rival Draco Malfoy and turned him into a [[DeadpanSnarker sarcastic]], leather-clad AntiHero best described as a combination of [[Literature/TheChroniclesOfAmber Corwin]], [[Series/BuffyTheVampireSlayer Spike]] and Literature/ArtemisFowl. Became wildly popular in fandom to the point where some fans began to [[BetterThanCanon prefer the Draco Trilogy to the actual canon]].

There was also a good deal of controversy in fandom when the author was blacklisted from Website/FanFictionDotNet for [[UsefulNotes/{{Plagiarism}} plagiarizing]] lengthy passages from a Creator/PamelaDean series without attribution (and, apparently, lying about having permission to use the passages in her fanfiction, although she did sort of get permission after she was caught). This is often confused with the series using a large amount of quotes and scenes from TV series (including ''Series/BuffyTheVampireSlayer'' and ''Series/{{Blackadder}}'') and several published works, which were (eventually) credited at the end of each chapter. Avocado, the person who first discovered and reported the Pamela Dean plagiarism, wrote [[ here]] a recount of the plagiarism debacle.

The author removed her fanfiction from the internet when she became a published professional, but rumor has it the Draco Trilogy can still be found online if you know where to look... for example, [[ here]], [[ here]], and [[ here]]!
!!The Draco Trilogy provided examples of:

* AbusiveParents: Lucius Malfoy, possibly the TropeMaker for Lucius being abusive, which is now considered a cliché in ''Harry Potter'' fanfiction
%%* AppliedPhlebotinum
* AuthorAppeal: The female characters are always excited whenever they get to wear old-fashioned {{Pimped Out Dress}}es which are [[CostumePorn thoroughly described]]--sometimes enough to temporarily overshadow in their minds the life-threatening circumstances they are in. The girls also tend to think a lot about how the boys in their lives smell differently. Apparently this is important in weighing their relative attractiveness--and no, none of them seem to actually smell bad.
* BeAWhoreToGetYourMan: When Harry and Hermione's relationship hits a rut in ''Draco Veritas'', Ginny suggests Hermione try this to get Harry's attention. Subverted in that Hermione tries it, but Harry hardly notices as he's naturally so busy angsting.
* BittersweetEnding: [[spoiler: Voldemort's defeated, Narcissa and Sirius are married, Harry and Draco are off to travel the world--but the two {{Official Couple}}s are (temporarily, at least) broken up]].
* BeautifulAllAlong: Hermione.
%%* CallingTheOldManOut
* CaptainOblivious: Harry. ''Dear God'', Harry. He fails to notice [[spoiler: Ron is having an affair, Hermione and he are having relationship problems, and that Draco (who he shares telepathy with) is ''dying''.]] However, Draco and Snape are pretty much the only ones who seem to be paying enough attention to realise all these things.
* CatchAFallingStar: The Weasleys rescue Harry in this manner at the end of ''Draco Dormiens''
* ClingyJealousGirl: Hermione, not just towards her boyfriend but towards all her guy friends. Lampshaded by various characters as they accuse her of not letting any girl (even Ginny, her friend) get close to 'her boys.'
* ComicallyMissingThePoint: In the third book, Lavender is asking Ginny which boys she prefers over others. She doesn't understand why asking her if she prefers Harry or [[BrotherSisterIncest Ron]] is "just sick" at first, but then remembers that Ginny used to have a crush on Harry.
* DamselInDistress: Hermione in ''Draco Sinister''.
* DancesAndBalls: Seem to happen a lot, including the [[FandomSpecificPlot usual and inexplicable re-staging of the Yule Ball]], although this series may be the TropeMaker there (well, aside fom ''[[Literature/HarryPotterAndTheGobletOfFire Goblet of Fire]]'', obviously). The weirdest instance of this: a formal ball is thrown for Harry's seventeenth birthday party in ''Draco Sinister''. Because Harry would have enjoyed that ''[[SarcasmMode way]]'' more than the low-key seventeenth birthday party he later had with the Weasleys in ''[[Literature/HarryPotterAndTheDeathlyHallows Deathly Hallows]]''. And whose idea was this? Sirius'! Because it's so in character for Sirius Black to throw a Creator/JaneAusten ball to usher his godson into wizarding adulthood.
* DeadpanSnarker: Initially Draco, but most of the main cast has this to some extent.
* DoorStopper: In terms of word count, the full trilogy is longer than the first six ''Harry Potter'' books. That's nearly twice the length of the original Russian version of ''Literature/WarAndPeace''. ''Literature/AtlasShrugged'' is less than two-thirds the length of ''The Draco Trilogy''.
* DefrostingIceQueen: Blaise and Draco.
* DrivenToSuicide: [[spoiler: Lucius Malfoy, with some help from Ron.]]
* FandomSpecificPlot: As noted above, the Yule Ball plot. In ''[[Literature/HarryPotterAndTheGobletOfFire Goblet of Fire]]'', the Yule Ball only happens during the Triwizard Tournament, takes place on Christmas day and is important enough to be attended by Ministry officials, with the most popular wizarding bands providing the music. In the Draco Trilogy, the Yule Ball is an annual event, takes place weeks before Christmas Break and is treated as little more than a high school prom. Seventh years actually regard the Yule Ball as beneath them, [[PartySchedulingGambit trumped]] by something called the Seventh Year Pub Crawl.
* FreakyFridayFlip: What the story starts off as.
* FunctionalMagic: Obviously present in ([[TransplantedCharacterFic most]]) ''Harry Potter'' fanfics, but notable here due to the considerable liberties the fanwork took with how magic works in the Potterverse, such as Lucious Malfoy getting his power from actual demons. Most of this is because Cassie started writing the trilogy between ''[[Literature/HarryPotterAndThePrisonerOfAzkaban Prisoner Of Azkaban]]'' and ''[[Literature/HarryPotterAndTheGobletOfFire Goblet of Fire,]]'' before the rules of magic were clearly established.
* "GravityIsAHarshMistress, but we have to work with her."
* HeelFaceTurn: Draco's character arc in the first story. Yes, present-day Draco fanfic writers, this trilogy actually ''bothers to explain why Draco is on the good side,'' instead of just taking it for granted that we'll buy Draco hanging out with the Golden Trio.
* GoodAdulteryBadAdultery: When Ron [[spoiler: sleeps with Hermione, who's actually Pansy in disguise, under dark magic]], then it's an unforgivable sin. When Hermione makes out with Draco and cuddles in bed with him for several nights, it's barely glossed over.
* HeroesWantRedHeads: Draco spends a great deal of the story involved with [[spoiler: Ginny Weasley]] and Ron with [[spoiler: red-haired Slytherin girl Blaise Zabini, who in canon was later revealed to be male, black, and not red-haired]].
* HeterosexualLifePartners: Harry and Draco. And Ginny and Blaise, by the end.
* HeyCatch: {{Lampshaded}}. Draco's horrified that he automatically caught the thing thrown at him.
* HookedUpAfterwards: Ron and Blaise, in the epilogue.
* HoYay: Loads and loads of Harry/Draco {{subtext}}. About halfway through ''Draco Veritas'', we get this little gem (paraphrased):
-->'''Harry:''' I love you.\\
''Draco:''' Whaaaaat?\\
(they get [[ChandlersLaw attacked by random mooks]], are understandably distracted, and it is never mentioned again.)
** There's even an in-universe kiss. Granted [[spoiler: it wasn't really Draco, just a Polyjuice hooker]] but Harry didn't seem to be complaining.....
** Also, Ben Gryffindor and Gareth Slytherin.
* IdenticalGrandson: The plot of ''Draco Sinister'' focuses on certain characters that are descendants and/or possibly reincarnations of the Hogwarts founders.
** Harry and Draco also look almost exactly like previous heirs Ben Gryffindor and Gareth Slytherin, to the point where Ron mistakes the latter for the former [[spoiler: in his vision.]]
* IHaveYouNowMyPretty: Salazar Slytherin's rather {{squick}}-inducing efforts to drug Hermione with love potion.
* InformedAbility: We're told that Draco can keep his emotions in check at all times, but he rarely does.
* {{Jerkass}}: Godric Gryffindor, despite being (supposedly) a good person. When you're smugly happy that a sixteen-year-old is dead, you're kind of a bastard.
* JerkWithAHeartOfGold: Snape and Draco.
* KissingCousins: The romance between [[spoiler: Sirius and Narcissa]], who were later shown to be cousins in the books but were not related in the Draco Trilogy. To be fair, though, virtually all the main characters end up being related.
** Technically there was a hint; at one point, Arthur Weasley mentions that the lengths blood purists go to to keep Muggles out of the bloodline means that all remaining pureblood families are related to one another, and the Weasleys, for example, are distant cousins to the Malfoys.
** Also, in Order of the Phoenix, it hints on pure-blood families marrying their cousins, which is part of the reason the Gaunt family was the way it ws. And, it's better than Sirius/Bella at any rate.
** An in-universe example: Ben and Gareth, who are heavily implied to be together despite being (second) cousins.
* KryptoniteFactor: Something called "adamantine" is basically kryptonite for wizards. Mainly it's there to stop Harry and Draco from resolving every plot in two seconds after they become [[UselessSuperpowers uber-powerful mega-wizards who don't need wimpy wands]]. Of course, even when adamantine isn't there, it's {{Lampshaded}} how thoroughly bad Harry and Draco are at being Magids, since they know very few spells and mostly have their wands anyway. In fact, Harry can barely do anything at all unless he's very, very angry.
* LostInImitation: A kind of fanfic version with the character of Draco Malfoy. Not portraying Draco as a two-dimensional bully was [[SeinfeldIsUnfunny actually a rather novel idea at the time]] and even after he turns good, doesn't stray too far (most of the time) from what a hypothetical redeemed version of the character might be like. Of course, only the positive aspects of her version of Draco were picked up on and years later fanfic!Draco had decayed from snarky anti-hero to misunderstood [[TheWoobie Woobie]] who wouldn't hurt a fly.
%%* LoveMakesYouCrazy
* LoveMakesYouEvil: Pansy.
* LoveTriangle: several. Namely: Harry/Hermione/Draco, Ron/Hermione/Harry, Draco/Ginny/Seamus, Ginny/Draco/Blaise.....
* MalevolentArchitecture: It's practically impossible to enter Malfoy Manor without getting killed at least three times.
* MissingEpisode: The author tried to [[InvokedTrope invoke]] this trope with regards to the whole fic, but the Internet has proved a WorthyOpponent.
** She seems to be winning, as of late. While ''Draco Dormiens'' is still fairly easy to find, the next two parts are becoming increasingly difficult to locate.
* NotListeningToMeAreYou: Sirius tells Harry he's changed his mind and decided to marry Remus instead of Narcissa. Harry, predictably, is too busy with his own problems to notice.
* OnlyAFleshWound: Characters constantly get wounds which could cause them to bleed to death in real life and having them completely shake it off.
** Averted when Draco is badly hurt by an arrow to the shoulder, and nearly dies. Also, when Ron's hand is badly burned, he's out of it for a considerable time.
* PowerPerversionPotential: Features a Polyjuice brothel!
* SealedEvilInACan: Salazar Slytherin.
* SheIsAllGrownUp: Ginny.
* ShoutOut: ''Draco Dormiens'' places Malfoy Manor near Chipping Sodbury, the birthplace of {{Creator/JK Rowling}}. The {{canon}} later placed it in Wiltshire.
** There's actually one to the EvilOverlordList. In ''Draco Sinister'', Draco notices Salazar Slytherin's personal library includes a book called ''The Handbook for Evil Overlords'', which "didn't look as if it had been read much."
* TakeThat: an unintentional one, given that it was written before the series finished, but happened when Hermione described how she believed she and Ron would end up together, and Harry and Ginny would too, and they'd spend ever Christmas together. Draco's response? "[[TastesLikeDiabetes How revolting]]."
** Actually, Draco delivers quite a few of these to the original series. For example, when Harry asks if being in love always feels like [[Literature/HarryPotterAndTheHalfBloodPrince having a huge, scary monster in your chest]], Draco responds "No, I think you have indigestion. I'd see a medi-wizard if I were you."
* {{Tuckerization}}: The character Rhysenn Malfoy is named after the author's friend, who wrote under the pen name of Rhysenn.
* UnbuiltTrope: As noted, this story named and brought prominence to the DracoInLeatherPants trope. It also spent a good deal of time showing how Draco would go from bad guy to good guy and the challenges he would face along the way.
* {{Yandere}}: Pansy Parkinson and, to an extent, Ginny Weasley.
