History FanFic / TheArithmancer

** In ''Lady Archimedes'', Hermione asks Anthony Goldstein to translate an ominous phrase into Hebrew; 'deplore' in the 'plural imperative intensive form' -- he says deplore doesn't translate and substitutes 'lament'. The answer, "''Qanenu''", is the invocation for the spell she calls [[spoiler:[[GreyGoo The Deplorable Word]]]]. She also asks for a translation for "I cast you out, unclean spirit" -- this one she uses in Biblical Greek, for two different spells -- "''S'ekballoume pneuma akatharon''" for [[spoiler:the de-Horcruxing ritual]] and "''S'ekballo eis to skotos to exoteron, esy pneuma akatharon''"[[note]]Approximate translation: "I cast you into the Outer Darkness, you unclean spirit!"[[/note]] for [[spoiler:destruction of Dementors]].

** Hermione points out that Mandrakes are literally PersonOfMassDestruction due to their lethal scream. If a malicious wizard put an amplifying charm on the plant it would result in the death of thousands. However Professor Sprout points out that the lethal effects are not instantaneous and that the scream cannot be reproduced artificially, such as recording the scream. [[BoringButPractical And that a silencing charm will render the mandrake harmless]].

--->'''Ron:''' Entwined pair of runes, [[LampshadeHanging remember?]] They're good for monitoring. When it breaks, we'll know [[spoiler:Lupin got out]].

* BrickJoke: After Hermione gets sorted a ''third'' time, the Sorting Hat tells her that if she does "manage to appear before me a ''fourth'' time", she'd go to Slytherin. Years later, while going to [[spoiler:Flitwick's office due to troubles her daughter caused]], the Sorting Hat [[ExactWords immediately shouts "Slytherin!" at her.]]

** Hermione deliberately builds a mundane solution into the D.A's contract as its obligatory CurseEscapeClause for the punishment for breaking it, banking that wizards wouldn't be likely to consider trying Muggle acne medicine. Though she acknowledges that [[spoiler:Seamus's father]], who is Muggle, might suggest the idea.
** This recurring belief lasts to the end of ''Lady Archimedes''--[[spoiler:Voldemort is able to use unsupported flight because his robes used flying carpet enchantments, rather than any obscure invented spell.]]

* MySignificanceSenseIsTingling: When a scene in Chapter 76 of ''The Arithmancer'' cut shows Ginny blowing up about Rita Skeeter getting her name wrong, Hermione (in a different country) turns to her friends and asks, "Did you hear something just now?" She concludes that she must have imagined it.

** At first, Harry doesn't think that stealing an egg from a nesting dragon sounds all that bad; at least he doesn't have to fight it. Then Hermione points out how Molly Weasley would react to someone kidnapping Ginny, and Harry decides he's doomed.

* RedBaron: Hermione has had a reputation for being "[[TitleDrop The Arithmancer]]" (with capital letters) since her fourth year, if not earlier. She goes by more 'titles' and aliases later on in the series.

** Professor Vector gets a fairly large one when Hermione reveals that her experiments could potentially [[spoiler:''create '''antimatter'''''. Or at least, she gets one once Hermione ''explains'' what antimatter is]].

* PetTheDog: Hermione helps Filch make a potion using rune clusters as part of her paper. He's so happy that the Twins thought it was the end of times.

* TiedTogetherShoelaceTrip: At the start of third year, Hermione tries to create a charm that would help her tie her shoelaces, as a first active attempt at spellcrafting. It doesn't turn out quite right and only manages to tie her shoelaces together. She later casts it on Draco Malfoy in Chapter 43, [[spoiler:saving him from being attacked by Buckbeak]].
* TitleDrop: In chapter 63, Luna introduces Hermione to her father as "The Arithmancer". Hermione is bewildered to note that [[CapitalLettersAreMagic she's hearing capital letters]].

** Arthur and Molly look over the photos of the Yule Ball, and Molly expresses concern about whether George's carelessness and lack of seriousness will corrupt Hermione. Cue scene change to Hermione working on a list of new hexes, starting with a Tooth Drilling Hex.

* PersonalityPowers: Hermione considers inventing a Tooth-Drilling Hex for Harry to use in the Triwizard Tournament, but eventually decides to save it for herself as the daughter of two dentists.

* AccidentalKiss: Harry and Ginny's lips touch by accident when [[spoiler:he's rescuing her from the Lake and sharing a Bubble-Head Charm with her]]. She has the presence of mind to linger for a moment.

* MySignificanceSenseIsTingling: When a scene cut shows Ginny blowing up about Rita Skeeter getting her name wrong, Hermione (on a different continent) turns to her friends and asks, "Did you hear something just now?" She concludes that she must have imagined it.

** Lampshaded by Hermione when her research and experimentation into magical extraction and purification of elements, making use of a suite of existing spells and new ones she's invented, plus modern technology like a Bunsen burner, results in a usable bronze knife.

* AdaptationalVillainy: In ''Lady Archimedes'', the author manages to pull this off with Umbridge -- who was already a villain in the original novels, by having her release even ''more'' Educational Decrees than canon (a full list by the end of fifth year is available in the ending footnote of Chapter 29), be openly racist to students in class, and actively do things that she only ''threatened'' to do (but got stopped) in canon, e.g. [[spoiler:Crucioing a student and enforcing corporal punishment]].

* AfterActionHealingDrama: The end of Chapter 67 to Chapter 69 of ''Lady Archimedes'' take place in the aftermath of the raid on Malfoy Manor, and primarily deal with several medical emergencies in the Weasley (extended) family that occurred either during or after the raid [[spoiler:and later the Death Eater attack that ensues.]]

** One of Ginny's nightmares, after surviving being taken into the Chamber of Secrets, is of Harry getting bitten by the basilisk, after having to slay it alone because Hermione has been petrified and Ron has been blocked by a cave-in, just like what happened in canon... [[DownerEnding except without Fawkes saving him]]. [[LampshadeHanging Hermione gets a feeling that this is exactly what Harry would've done had he actually been in this situation]].

*** [[spoiler:Tilly]] died to protect the younger students when [[WouldHurtAChild the Death Eaters went for them]] after Voldemort's fall.

** Hermione, in the aftermath. Everyone knows that attacking her is a deadly mistake. And this is especially true [[HorrifyingTheHorror among Dementors]], whom she has made a personal project to [[DefeatingTheUndefeatable eradicate]]. [[RedBaron They call her, among other epithets, "the Angel of Death" and "The Destroyer", and the American Aurors call her "the Demonslayer".]]

** Either this Trope or DiesDifferentlyInAdaptation: [[spoiler:Fenrir Greyback]] is [[OffWithHisHead beheaded]] with Snickersnack in the Death Eater attack on [[spoiler:the University of Nottingham Hospital]], while his canonical fate is ambiguous (either death or post-war imprisonment in Azkaban).

*** Either this Trope or DiesDifferentlyInAdaptation: [[spoiler:Antonin Dolohov]] is killed by [[spoiler:the Weasley Twins with their prank products]], when he is defeated by [[spoiler:Professor Flitwick]] in canon with his fate (life/death) left ambiguous.

** The Hogwarts house elves are mistrustful of Dobby's desire to remain free, and assign him to the most menial tasks like cleaning the boys' toilets. Hermione starts to think about pushing for laws to protect him, and then realises that she wants anti-discrimination laws to ''protect the free workers from the slaves''.

* TrappedTheWrongTarget: Played for laughs when Hermione plans a prank on Fred and George involving runes set up to activate a waltzing jinx (of her own invention) on the next pair of twins to enter the Gryffindor common room. Unfortunately, she doesn't count on Padma Patil picking that day to come by for a visit....

* BadassBoast: There are a number throughout the series, including a direct reference to [[Literature/TheLordOfTheRings Galadriel's "All Shall Love Me And Despair" speech]] in Chapter 47 of ''Lady Archimedes''. But perhaps the most impressive is when she snares a curse out of the air, deconstructs it while giving commentary, and collapses it harmlessly, just before the aforementioned LOTR ShoutOut.

** In first year, Professor Vector pales in shock when Hermione tells her that Harry is going after the Stone by himself... and then pales further and ''bolts'' when she adds that he knows how to get past Fluffy, since that means he's going to encounter the Devil's Snare, which is much more dangerous. [[spoiler:And both Vector and Harry are "chalk white with fear" when they see that Vector's trap, which she had thought arithmantically impossible for ''Hermione'' to bypass much less an ordinary person, has somehow been defeated.]]

* OnlyKnownByTheirNickname: Sonya the House Elf's full given name is Sonnitt, but is only called that by her grandmother, Tilly, and the Hogwarts Professors.

** As Snape is still alive during the Battle of Hogwarts, [[spoiler: he uses the Killing Curse to instantly take down an attacking giant. This immediately makes him a target for several Killing Curses from death eaters.]]

* SoulJar: As per canon, Voldemort creates Horcruxes as safeguards for his immortality, but they are destroyed throughout the series. [[spoiler:In the late chapters of ''Lady Archimedes'', Harry and Ginny become light-oriented Horcruxes (later named "Miracruxes") in the rituals used to remove Voldemort's soul fragment from Harry.]] And later in ''Annals'', [[spoiler:Barty Crouch Jr is revealed to have created his ''own'' Horcrux to safeguard his life from capture by Light forces.]]
* SparedByTheAdaptation: There's a fair list of them--[[spoiler:Cedric, Sirius, Remus, Tonks, Fred, Astoria (using non-magical medicine and a fortifying elixir from Hufflepuff's Chalice/Cup to treat her blood curse), and possibly others.]]

* GodzillaThreshold: Hermione crosses this during the final battle. [[spoiler:She ultimately kills Bellatrix with her invention, [[GreyGoo The Deplorable Word]], which she spent most of the book trying to keep secret.]]

* SoulJar: As per canon, Voldemort creates Horcruxes as safeguards for his immortality, but they are destroyed throughout the series. [[spoiler:In the late chapters of ''Lady Archimedes'', Harry and Ginny become light-oriented Horcruxes (later named "Miracruxes") in the rituals used to remove Voldemort's soul fragment from Harry.]] And later in ''Annals'', [[spoiler:Barty Crouch Jr is revealed to have created his ''own'' Horcrux to safeguard his life from capture by Light forces.]]

* {{Hypocrite}}: PlayedForLaughs when Sirius and Remus are cleaning out Grimmauld Place and doing battle with the pest species living there.

* AintNoRule: One of Hermione's most common tricks against Dolores Umbridge throughout her fifth year, though the bureaucrat quickly adopts new rules to close what is, in her power-addled mind, LoopholeAbuse. Later {{inverted|Trope}}, as Hermione discovers that there ''is'' a rule specifically stating that Hogwarts students are allowed to carry swords, one which is centuries old but still entirely viable.

* AsTheGoodBookSays: As she studies soul magic in order to understand Horcruxes (including the one in Harry), Hermione purchases religious books in Chapter 64 of ''Lady Archimedes''. She later "borrows" a Bible in Chapter 71 while on the run from the Death Eaters, and [[spoiler:bases one of the de-Horcruxing rituals on a passage from the ''Book of Job'']]. Oh, and she also makes emergency rations based on Manna--down to the taste, even--from natural resources (e.g. dirt and wood), and goes out of her way to make it fulfill the nutritional requirements to survive.

** Umbridge bans teachers from giving students any information that isn't related to the subjects that they're paid to teach -- so Hermione hands Professor Vector a coin and they continue discussing advanced Arithmancy as usual. When Umbridge finds out and bans teachers from teaching any classes outside the approved curriculum, ''Professor Vector'' starts paying ''Hermione'' a sickle per week to teach her "Advanced Topics in Mathematics", of which she is qualified to do so by Fifth Year. Umbridge ends up having to ban Hogwarts ''teachers'' from pursuing an active education while working as a professor at the school.

* EvilCounterpart: Voldemort's traitor Unspeakable Augustus Rookwood, who is a spellcrafter almost as good as Hermione and can use a Pensieve to recreate her best work.
* ExactWords: Hermione doesn't like lying, but freely makes use of this.

* EvilCounterpart: Voldemort's traitor Unspeakable Augustus Rookwood, who is a spellcrafter almost as good as Hermione [[OhCrap and can use a Pensieve to recreate her best work]].

* GreyGoo: Hermione worries that this is possible with the use of transfiguration and runecraft. [[OhCrap It is]] -- though fortunately it's hard to make it fully self-sustaining by accident.
