Dumbledore's Army and the Year of Darkness began as a one-shot, 4,000-word Harry Potter fanfic story entitled Dumbledore's Army: Still Recruiting. According to the author, he soon found himself "up to [his] pointed hat in the most out-of-control one-shot in the history of the wizarding world."
DAYD, as it is known, is a P.O.V. Sequel that happens at the same time as the story of Deathly Hallows. It follows one of Harry's friends, Neville Longbottom, as he takes control of the underground group Dumbledore's Army, who soon begin a revolt and prepare for an all-or-nothing war against Lord Voldemort.
The tale continues in Sluagh.note It is now five years later, all the survivors have moved on to civilian life, each nursing his and her own trauma scars. Neville is senior Auror and Simon-Wiesenthal-in-residence (so to speak) for the rebuilt Ministry of Magic, tasked with rounding up the remnants of Voldemort's henchmen. For his final assignment, he is dispatched to track down a mysterious serial/vigilante killer in Ireland and ends up fighting an even more sinister and brutal dark lord than Voldemort.
The concluding novel of the trilogy, A Peccatis,note picks up in 2008. Strapped for money (the recession rippled into the wizarding world too), Neville is finally talked into joining the Wizarding legislature just as a vote on officially breaking the masquerade is pending. All the while, Dumbledore's darkest secrets are coming to light. Though a word of warning: the most recent chapter was posted on the 9th of October 2012, and the author has moved on through at least two or three more fandoms since then with no word on when they'll be returning.
DAYD exploded into a Fan Verse, the DAYDverse, and now comprises more than half a million words by the original author in the form of the two complete novels (Dumbledore's Army and the Year of Darkness and Sluagh) with a third novel in progress (A Peccatis), along with numerous one-shots and short stories exploring various other characters. Other authors have come to play in that world as well, most notably Ceirdwenfc, who has written stories about Ernie and Susan and is currently working on a novel, Bittersweet, which is yet another P.O.V. Sequel and follows Ernie's experiences during DAYD.
There is an extensive, and ongoing, YMMV discussion concerning themes, quality, Canon Defilement, and sundry other matters.
As of December of 2017, Thanfiction's account has been deactivated.
Tropes applying generally:
- Anyone Can Die: In the Battle of Hogwarts, the brutal deaths of Dennis, Michael, Cho, Parvati and too many others come as shocks. Continued with alarming enthusiasm in the sequels. Basically, anyone who did not get an explicit name check as being alive and well in Rowling's epilogue can be presumed to be dead by the time the trilogy has run its course. And even that is no guarantee, because "Epilogue? What Epilogue?"
- Big Bad: As in the books, ultimately, Voldemort. Memories of the horror of his reign and the extremes required to end it echo through the sequels.
- Bloodier and Gorier: This fic series has a LOT of very explicitly described violence, rape, gore, and torture. It's based on Harry Potter, a Children's/Young Adult series.
- Breather Episode: Multiple:
- The author does attempt to put a few comic episodes in between the doom and gloom. Like a Fish out of Water scene where Neville and co. attempt (with more success than most wizards) to navigate the byzantine mazes that is British Rail and Marks & Spencer to get to a wedding. And a similar episode in 'Sluagh' where Neville and Utterson try to pump a muggle cultural anthropologist for information on magical sites in Ireland.
- Also during the run-up to the battle of Hogwarts, persecution by the Death Eaters has driven most of the student body into the safety of the Room of Requirement, which quickly assumed the atmosphere of a rather morbid slumber party. The students noted how ironic it is that the only time they got to relax in the whole year was the week before they will go into a suicidal battle.
- Call to Agriculture: Neville's potential for incredible badassery and his love of herbology are in even bigger contrast with each other than in Canon. He often declares how much he would prefer simple gardening over leading an army. He eventually gets it, with interruptions.
- The Cameo: Peripheral characters from previous books tend to drop by for a scene or two, and most likely, get killed in the process.
- Crapsack World: The wizarding world is becoming this. And Sluagh somehow managed to mesh the worst of the Troubles in Northern Ireland with the worst of Voldemort's reign of terror.
- Crazy-Prepared: Hermione, whose method of dealing with PTSD involves carrying around enough supplies to stock half an army in her magic purse absolutely everywhere.
- Darker and Edgier: DAYD itself compared to Canon; Sluagh, goes even further with a few sections with very detailed descriptions of the rape and torture of Hermione. And A Peccatis seems determined to examine all the warts and seams of the wizarding world in general.
- Dead Guy Junior: Thanfiction is especially prone to this. IIRC, there are only three kids who aren't named after dead people, and two were adopted from another country. Of course, there are a lot of names to choose from...
- Did Not Do the Bloody Research: If you speak British or Irish English, be prepared to hit stuff a lot. Thanfiction's ignorance about European languages is painfully obvious, with use of words like "sweater" or "curb" instead of "jumper" and "kerb."
- Fan Verse: Starts with a parallel story to Harry Potter and the Deathly Hallows and continues with the second of three books called "Sluagh," as well as numerous one-shots, missing scenes, and character profiles.
- Doesn't even begin to describe the Battle of Hogwarts. Gory descriptions include a girl being slashed to bloody shreds by a curse, Lavender having her throat torn and mangled, a giant crushing a student like jelly, and Michael's head smashed open so his exposed brain gleams white.
- Sluagh ups the ante, with Seamus Finnigan ritually torturing and slowly eviscerating his targets while they are still alive, Bill getting his limbs ripped off and buried alive, Ginny being impaled and her heart ripped out by a sentient tree, and the less said about what happened to Ron and Hermione, the better.
- The author seems to be backpedalling from this, people are still dying left and right in A Peccatis but a lot more bloodlessly.
- Heroic Build: Much attention is paid to the boys' rippling muscles and the girls' curvaceous fragility, even where the original books had hitherto failed to mention fragile curves or a penchant for rippling.
- Hold Your Hippogriffs: The author (in imitation of Rowling) has an occasional tendency to make up "wizarding" idioms, like "witches' instinct" for "women's intuition".
- Kill 'Em All:
- The Battle of Hogwarts puts up a valiant attempt to carry out this trope on the protagonists with some very nasty curses involved.
- Sluagh, is worse. Depending on how you look at it, none of Our Heroes are left standing after the Battle of Druim Cett, albeit temporarily, and if half of those creatures aren't out of the author's imagination, there's some funky stuff in water of those Irish springs.
- A Peccatis seems to be doing this to the previous generation.
- MST: The fic has received several sporkings.
- National Stereotypes: Multiple:
- Seamus and the other Irish characters pretty much cover all of the major Irish stereotypes, and by Sluagh, Thanfiction starts to resurrect some of the stock Irish characters from the Victorian era.
- The stereotyping covers the spectrum: starting with Cho, a Chinese girl who is indistinguishable from her English neighbour; to Parvati and Padma, who are attracted to some superficial trappings of their Indian heritage (e.g. the cooking and Yoga); to Ernie, a fully-rounded character who is just happens to be quite Scottish; to Seamus, who looks like he wandered in from an Irish epic and the author spends every other chapter making sure you get that.
- Oireland: Multiple:
"Tell you what. You say one word, and I'll make it worth your while. I've smuggled in a bit of the real good stuff Muggle-made Irish pure and I'll slip you a tot. Or if you'd rather, I'll work my charms and score you a kiss from that lovely Miss MacDonald you've been castin' eyes at all year. What say you?" DAYD, (Chapter 11).
- Seamus Finnegan gets turned into this, JK Rowling has said that naming the character "Seamus Finnegan" was pushing it a bit, but Thanfiction takes the Irish stereotype Up to Eleven. Example:
- Now consider that he didn't have anything resembling that thick an accent in canon. Oh, and he knows Druidic rituals, as well.
- Even worse, Slaugh has several sequences in an Ireland torn and devastated by the Troubles... even though it takes place three years after the end of Harry Potter and the Deathly Hallows. For those who don't know the Harry Potter timeline, Deathly Hallows takes place in 1998, the year the Good Friday Agreement was signed; while it's ridiculous to say that brought an immediate end to all the fighting, the story doesn't seem to realize there was any sort of action at all.
- One-Word Title: Slaugh, named for destructive, restless spirits of the dead in Irish mythology.
- P.O.V. Sequel: To Deathly Hallows, presenting the events of the book from Neville's [POV].
- Purely Aesthetic Glasses: Terry Boot had these when he was younger, to appear intelligent so the Sorting Hat would put him in Ravenclaw.
- There Are No Therapists: Lampshaded, the students of Hogwarts survived a year of genocidal torture and war, and all they have at the end are each other for comfort. The only thing the wizarding world at large tossed them is a bunch of nosy reporters. Everyone ended up learning to deal with his or her PTSD themselves. Some retreated into domesticity, some became lawmen, one became a vigilante serial killer, another became a drug addict, and everyone had nightmares.
- Took A Level In Jerk Ass: Neville becomes more and more of a Jerk Ass Stu as the fic goes on. Mostly this is due to the fact that he starts to see himself as a military leader and begins to expect military discipline from his underlings, while the said underlings still see him as their fellow classmate.
- The Troubles: The fic handles the subject remarkably well considering it's a Harry Potter fanfic. DA partisan Seamus Finnigan, who in the DAYDverse is from Belfast, uses the Troubles as a counter-example to wizards' overly romanticized view of the Muggle world. The conflict plays a major role in the plot of Sluagh. Of course, Sluagh also gets it wrong, being set in 2003, while The Provos broke apart in 1998. The "Real IRA" has a tendency to set itself apart from the Regular IRA, which many members consider 'quitters'.
- The 'Verse
Tropes applying specifically to Dumbledore's Army and the Year of Darkness:
- A Day in the Limelight: Most of the supporting characters get a few stories about them. The original novels are also this.
- Terry Boot and Michael Corner (in various short stories)
- Ernie Macmillan and Susan Bones (in Bittersweet and other works by Ceirdwenfc)
- Colin Creevey and Demelza Robins (Breaking Eggs and Snapshots)
- The various 20 Random Facts About...
- Arson, Murder, and Jaywalking: Ginny rattles off a list of equipment she's managed to smuggle into the castle, finishing with "and some Pygmy Puff treats for Arnold".
- Artistic License Geography:
- Scotland does not have a Himalayas-like climate, despite the assertion while explaining a hidden Demiguise farm. Also, demiguises are described as wild and ape-like in ''Fantastic Beasts and Where to Find Them''; the fic treats them as some sort of invisible domestic sheep.
- In one scene, Neville and several characters use a National Express East Coast train as part of a journey to Gretna Green. In 1997/98, the route from King's Cross to the North was controlled by Great North Eastern Railway...and the far more convenient way to get to Gretna Green by train is via the line from Euston to Carlisle.
- Artistic License Medicine: The blood transfusion in Chapter 10 of DAYD, done without any attempt at cross-matching bloodtypes, and with two people donating blood, was quite risky, with about a 35% chance Colin would die from bloodtype incompatibility note .
- Ascended Fanboy:
- Colin, an out-and-out Pop-Cultured Badass who loves Star Wars, plays Dungeons & Dragons, and even says he's "living the fantasy." It also explains his hero-worship of Harry and general hyperactivity throughout canon.
- It's clearest when Neville meets Colin's childhood friend Brad, who is under the impression that Neville is "Lawful Good", and in this companion oneshot.
- Becoming the Mask: From the perspective of Hogwarts students in 1997-8, there's no real difference between Severus Snape pretending to be evil so as not to make Voldemort suspicious, and Snape actually being evil.
- Beware the Nice Ones: Dennis Creevey is one of the sweetest, nicest boys you could ask for... until the Death Eaters finally push him too far. "AVADA KEDAVRA YOU SON OF A BITCH!]]"
- Broken Pedestal:
- Harry is... confusing, when viewed through Neville's eyes. While Neville and the D.A. had spent the whole year planning, drilling, accepting the likelihood of their wholesale slaughter against the Death Eaters, they've also been relying on each other for friendship, love and support. Harry, on the other hand, has experienced isolation, panic and dread with barely any respite, so when he finally stumbles back into Hogwarts, he has all the disconnect and PTSD you'd expect. But from the D.A.'s perspective, Harry has none of the spark of revolution or excitement they'd expected. It's strongly implied that Neville's summoning of the entire D.A. and allies from the wizarding world for the final battle is less a function of his gee-whiz enthusiasm (as presented in the official canon) and more a tactic to keep the D.A. from imploding out of disappointment.
- Also, a different pedestal breaks in Seamus and Neville's horrified reactions when they find out that Dumbledore's "plan" was a lot more of Gambit Roulette than Batman Gambit:"Din't you know ol' Dumbledore din't tell them anythin'? They were out there, tryin' not ta get killed, wanderin' around for better part o' a year on a little breadcrumb scavenger hunt, no bleedin' idea o' what they were doin', or what they'd do when they were done."
'There has to be a reason, Seamus.' He fought to keep his voice calm, reasonable, but he could hear the tremble of fury and newly-awakened pain at the edges. 'I'm sure he had a reason.'
- The Caper: Neville and company pull one of these to retrieve the Sword of Gryffindor from Snape's office, complete with seemingly impossible odds on getting inside.
- The Casanova:
"I did just fine with the Muggle girls on holidays, thank you very much, because they think I'm cute and mysterious and know I go to some kind of exclusive and super-secret private boarding school.
- Apparently, Colin Creevey of all people.
- Child Soldiers: At least half of the members of the Dumbledore's Army die horribly, and a good amount are crippled or killed in the sequel. However, the fic tends to glorify the hardened child soldiers in comparison to Harry, who hasn't embraced the military mindset. What's more, it gets taken to utterly ludicrous levels. Somehow, they manage to form a complete mock-military structure despite being from a culture with no armed forces, develop a martyrdom mindset that in real life requires indoctrination from toddlerhood, and in general make an absolute mockery out of the subject. And the injuries they suffer are only terrible because the author's forgotten the Harry Potter universe has extremely powerful magical healing.
- Cold-Blooded Torture: The Cruciatus Curse is used as routine punishment, to the point where the students get used to it and that doesn't even begin to compare with what Doctor Belsen does to Mike Corner (his best friend tries to euthanize him half-way through the torture session).
- Collateral Angst: One of the many things people take offense to in the fic is its treatment of Lavender's rape. After it's revealed, the victim is only referred to by name perhaps twice in the following scenes. Instead, Neville gathers an (exclusively male) revenge squad, humiliates the attackers (something that in real life would more likely drive them to repeat their crimes, as their egos are now damaged), and calls it paid.
- Death Seeker: Most of the D.A. slips into this. At the beginning of the story they decide that they will all go on a suicide attack as a protest/revenge/hopeless last stand at the end of the year rather than continuing to live under the current regime. Some of them were also talking, even joking, quite detachedly about their upcoming deaths.
- What would the events of Harry Potter and the Deathly Hallows look like if you think about them in the context of our world? (torture in school, child soldiers, etc.)
- Most notably, the same Battle of Hogwarts is portrayed as an actual battle, with lots of gorn, as opposed to Rowling's lighter portrayal of the house elves, ghosts, Sybill Trelawney, and Neville throwing stuff at the Death Eaters' heads.
- Did You Just Punch Out Cthulhu?: Ernie Macmillan has the stones to punch out a Dementor. Yeah, he goes down... but he tried. And he gave his secret wife, Susan Bones Macmillan time to whip out her wand and summon her Patronus.
- Disproportionate Retribution:
- When Renny, a young Slytherin, gets caught with a copy of the Quibbler in his bag, he gets his arms broken by Crabbe and Goyle for being a "blood traitor." Then his dad pulls him out of the school. Then Voldemort murders him along with his whole family. Renny's story was one of the greatest Tear Jerker moments in the fic.
- The Death Eaters respond to the students rebelling by inviting Hans Belsen (a cross between Mengele and Tomás de Torquemada) to make an example out of a few students.
- Double Standard: Abuse, Female on Male/ Yandere: Hannah Abbot (Neville's future wife) tries to set him on fire and then throws several potted plants at him (one of which suffocates him to unconsciousness, while she does nothing to stop it). All this because of a bad case of Poor Communication Kills leading her to believe he was making out with Ginny—even though Hannah and Neville aren't even dating. Either this is supposed to be justified by the "fact" that girls are just crazy like that or a bit of comic SlapStick horribly clashing with the deadly seriousness that violence is portrayed in the rest of the fic. It is possible that this is a continuity nod of sorts to the scene where Hermione sets a flock of conjured birds on Ron, albeit a ridiculously over the top one.
- Evil Teacher: Snape and the Carrow siblings, who gleefully torture students (to a greater extent than canon, and in some cases contradicting canon).
- Eye Scream: Dennis Creevey kills the Death Eater who killed his brother by jamming his wand into the Death Eater's eye and screaming "AVADA KEDAVRA, YOU SON OF A BITCH!" Unfortunately, it's a mutual kill.
- Flanderisation: Snape goes from a morally grey Anti-Villain who, it's implied, used his post as headmaster to control the Carrow's sadism, to an out-and-out Death Eater who gleefully tortures children.
- Funny Spoon: Luna Lovegood can do magic with a spoon replacing her wand. Which she uses to make a picture made from food permanent, instead of using it to escape and break her friends out.
- HeelFace Turn: Renny, son of a Death Eater who joined the D.A. after Voldemort tortured his father for a minor failure. See "Noble Bigot".
- Hive Mind: The female characters, who are capable of communicating on a 'frequency only other girls could understand'. This is mostly used for facilitating the rapid spread of gossip.
- In Medias Res: In canon, Neville's a bumbling, timid boy with a hidden core of steel that comes out when the shit hits the fan. During his 7th year, the challenges force him to grow up, and the awesome qualities hinted at before come to the forefront. However, DAYD skips over this Character Development completely: The fanfic starts with him having already grown up, and he then gains everyone's respect over the course of a single speech in the first chapter. Presumably, Thanfiction just wasn't interested in that part of the story, but it produces rather a disconnect from canon. Luckily, the fic's main story starts immediately after that Handwave.
- The Lad-ette: It was hinted at in HP canon, and this fic makes it explicit — Ginny Weasley:Im the only girl in a family of seven! I could belch the entire Chudley Cannons fight song by the time I was four, but Katie Bell had to tell me when I needed a bra and show me how to put the effing thing on, so dont act like Im supposed to be some sheltered little flower about how boys are put together.
- National Stereotypes: Marks & Spencer is not the stuffy and upper-class department store presented in the fic; in reality M&S is closer to J.C. Penney. (The author might have confused it with Harrod's, which is that stuffy and upper-class, and more.)
- Noble Bigot: Various DA members who happen to believe in pureblood supremacy. Rather oddly handled, though - in many cases, their only noble quality is being willing to fight Voldemort, and they still seem to hate all the mudbloods and non-bigots they're fighting with.
- Ooh, Me Accent's Slipping: The first fic itself commits a variant. It makes a credible effort at imitate Rowling's own style, but American spellings such as "mom" and "curb" and words such as "sweater" spoil the effect.
- Precision F-Strike:
- Dennis: "Avada Kedavra, you SON OF A BITCH!"
- Ernie: "Thats my wife, you BITCH!"
- Neville: I know my BLOODY plants!
- Rape as Drama: Lavender's rape by Crabbe and Goyle is primarily used as a Kick the Dog moment to further motivate Neville and company. Lavender has very little agency in the Roaring Rampage of Revenge that follows. The reader is left with the feeling that it wasn't as much about the rape victim's feelings, as much as Neville's male honor being sullied. The revenge squad consists only of men, and after their vengeance is over, the rape is barely mentioned at all. Addressed in a later fic, from Lavender's POV - "Underpinnings."
- Reality Ensues: Let's face it—those kids never really stood a chance of doing anything but keeping the Death Eaters busy while Harry dealt with Voldemort. Teenagers against adults who have spent the better parts of their lives learning to use magic designed to inflict pain, suffering, and death? The D.A. is lucky they lasted as long as they did.
- Real Person Cameo: Natalie McDonald, a real girl that Rowling cameo'd in Goblet of Fire. So, basically, she is here as a cameo of a cameo. It's worth noting that she's basically there to die during the final battle... while her namesake died of cancer in real life before Goblet came out.
- "Shaggy Dog" Story: Chapter 18. Hans Belsen, basically an Expy of Josef Mengele, shows up to the school because he wants to torture children. When Neville and Jack Sloper insult him later that chapter, he immediately leaves the school instead of, you know, torturing them."BAM! Other side of his face goes, and Alecto was so furious, she kicked him out of the class. Said he had lost the privilege of learning from Belsen. So that's when I raised my hand and asked if I could lose the privilege too, and Belsen just gave the whole class this long look, looked back at Alecto, and told her that he had been under the impression the teachers controlled Hogwarts, not the students, and he left." — Jack Sloper describing the surprisingly quick defeat of Nazi torturers.
- Slut-Shaming: One of the most uncomfortable moments comes after Lavender is raped. Neville sits her down and tells her that he knows all the rumors about her sexuality are false, even if she is a flirt, because he knows she doesn't sleep around. The end result is that he sounds very, very much like he's saying she would deserve to be raped if she did sleep around.
- "Take That!" Kiss: Neville kisses Draco to humiliate him.
- Tastes Like Diabetes: Invoked, when Hannah tells Neville that her Aunt has some sickeningly cute collectible china witch figurines. Apparently, "It's like trying to eat half of Honeydukes in one sitting. You can feel your teeth start to rot the second you cross the front door."
- Took a Level in Badass: The fic is all about Neville Longbottom, and the DA, levelling up in Badass to the point where they're able to stand up to, and fight, Death Eaters on a nearly-equal-to-equal basis.
- Torture Technician:
- The Carrows regularly try new torture methods on rebellious students.
- Never mind Professor Hans Belsen, brought in (if briefly) to demonstrate his research on unruly students. Given that he is plainly based on real Nazi scientists.... * shudder*
- War Is Glorious: The fic has a strange relationship with this trope and War Is Hell. On the one hand, Thanfiction bangs the drum of how horrible the final battle will be... but on the other hand, most of the DA are quite excited by the prospect of fighting Voldemort. The story plays them up and contrasts them to Harry and company, who try to avoid the war entirely... in the favor of the children about to be slaughtered. All in all, the story's schizophrenic.
- War Is Hell: The fic is a prime example, depicting the horrific ordeal the members of the eponymous insurgency go through to keep the darkness at bay as best they could, culminating in a final battle (the Battle of Hogwarts from the book, retold from their perspective) in which almost everyone dies. Unfortunately, it fumbles that ball badly, as the vast majority of the DA want to fight, have embraced the fact most of them will die, and when someone tries to convince them not to fight, he's portrayed as being in the wrong. The themes clash so badly that the entire story is tainted.
- Wartime Wedding: Susan Bones and Ernie Macmillan. Professor McGonagall also told a backstory about herself marrying a wizard who joined the Muggle RAF in WWII and died shortly afterward.
Tropes applying specifically to Sluagh:
- Anti-Hero: Seamus Finnigan, whose method to defeat the Big Bad in Sluagh is by ritually torturing and murdering his recruits both current and potential.
- Bilingual Bonus / Meaningful Name: The Big Bad in Sluagh is The Diabhal Dubh, explained In-Story to mean 'The Black Devil' in Gaelic. What isn't explained is that Dubh can also mean several other things, including 'Hidden'. Given his nature, this is very appropriate.
- Bi the Way: Icarus Utterson, as revealed in his 20 Random Facts...
- Enemy Mine: Apparently a Wizard Big Bad is exactly what's needed to get the Real IRA and the Unionist militia to work together.
- Fantasy Gun Control: Averted, as Seamus is equally adept with a firearm as with a wand, and the muggle militiamen stand their own against the onslaught of magicians during the battle of Druim Cett. As Seamus noted, waving around a machine pistol in wartorn Belfast attracts far less attention than brandishing a wooden stick that shoots red thunderbolts.
- Flashed-Badge Hijack: Neville attempted to do this to a Muggle with his wizard Auror badge. It worked the first time as it was too dark to see the badge properly. The second time the Muggle assumed it was a joke until Neville transfigured a teacup into a gerbil in front of her.
- Funetik Aksent: The Irish, in a ridiculously exaggerated way.
- Genre Roulette: The first half of Sluagh reads like a hard-boiled detective story, morphs into a war epic, then into eldritch horror around the Battle of Druim Cett, and then turns into high fantasy (complete with mythic landscapes and Gods), all of which clashed quite a bit with Rowling's brand of Urban Fantasy. Also, there are shifts within the shifts and they occur with little to no warning.
- Going Native: Neville, working undercover as an enforcer for the Real IRA, starts to accept their tactics and goals.
- Northern Ireland: Large parts of Sluagh takes place in and around grimy Belfast, where the rabid remnants of the Unionist and Nationalist militias are still fighting a bloody gang war - in 2003, despite the fact that The Troubles basically ended in 1998. All things considered, the setting is more reminiscent of the desperately poor 1970s-1980s Ireland at the height of The Troubles than the modern Celtic Tiger Ireland.
- Oh, Crap!: After suffering heavy losses breaching the outer defenses at the Battle of Druim Cett, Neville and company realizes that the Big Bad is surrounded by a magical army of hundreds (not to mention a homicidal sentient forest), not the seventy men as previously reported, cue trope.
- Reset Button: Battle of Druim Cett, every good wizard character that died comes back to life due to the intervention of the Celtic Gods (considering Rowling's canonical epilogue is set in 2017 and Sluagh is set in 2003, there is really not much of a choice for the author).
- Retirony: Played with, as Neville is on his last case with the Aurors. Needless to say, He dies then comes back to life.
- To Unmasque the World: The Masquerade is already seriously cracking in Ireland, where wizards are openly working for the militias. And this is the ultimate goal of Diabhal Dubh, who wants to take over Ireland by building up a united muggle and magical army.
Tropes applying specifically to A Peccatis (unfinished):
- Broken Masquerade: Wizarding England has realized that muggle technology is rapidly catching up and that the War killed or exiled too many of the wizards who are needed to maintain the magical infrastructure, and they are going to call a vote on breaking the masquerade, True Blood-style.
- Da Chief: Harry Potter, as the head of the Auror Office.
- Dead Fic: Has not been updated since 9th of October 2012, and the author has moved on through at least two or three more fandoms.
- Genre Shift: A Peccatis keeps switching unpredictably between police procedural and political conspiracy thriller.
- Gratuitous Latin: A Peccatis, where all the chapter titles are in Latin.
- It's the Only Way to Be Sure: The Assurance faction, which has arisen in the decade since the end of the Second Wizarding War. According to Draco, they want to see everyone who was associated with Voldemort — along with their families — killed. They feel it's the only way to stamp out the lineage of Dark Wizards for good.
- King Incognito: Justin Finch-Fletchley brings "a friend from the RAF" to the Leaky Cauldron to meet Neville and Hannah. The "friend" turns out to be Prince William.
- Reading Your Rights: Aurors are saddled with a wonderfully verbose version of the British police caution in order to plug in the extra legal loopholes that being magical might present. Legal buffs might care to notice that in the Wizarding version, the right to remain silent (which is front and center in the Caution and Miranda) is the second-to-last thing mentioned. Also please note that unlike the caution, this one is to be recited upon arrest (or when the suspect wakes up from all the stunning spells), not interrogation. It reads as follows:It is my duty that you be made aware of your standing under the Provision of Magical Rights and Liberties. You have been apprehended by officers of the Department of Magical Law Enforcement while engaging in activities reasonably believed to be criminal in nature, and there is intent to hold you in violation of the law. Your wand has been confiscated and may not be returned to you unless you are exonerated of charges by the Wizengamot or equivalent legal due process. Officers of the Department of Magical Law Enforcement may use physical or magical force against you, including such as may cause permanent harm, injury, illness, incapacitation, or death if and only to the degree as is necessary to retain you in custody and to safeguard their own welfare as well as that of others. Any statement or incantation you may say or perform, including via non-verbal means may be used as evidence in a criminal proceeding. You are considered to be innocent until such time as guilt is reasonably proven, however your apprehension in situ is considered temporary grounds upon which you have waived your right to liberty at this time. You have the right to refuse to answer questions, however any false or misleading answers given will result in additional criminal charges. If you believe yourself to be operating under a curse, hex, jinx, or otherwise engaging in your current activities under magical coercion, you may indicate as such at any time. Additional rights and exclusions under wizarding law will be explained to you fully and completely as relevant. Do you understand these rights and exclusions?
- Reality Ensues: From 1997 through 1998, Wizarding Britain was taken over by a far right terrorist group focused on cleansing the magical society of Muggle Borns and impure bloodlines. Even a decade after they were stopped, is it really a surprise that Muggle Borns have left the Wizarding world or are refusing to send their children to Hogwarts for fear the insanity will start all over again?
- Secret Diary: A Peccatis starts with Neville and Harry receiving, and having to figure out the meaning of, isolated pages from Dumbledore's diary.
