Fic Masterlist
Hello! I'm thistlecat on ao3. I've been reading Harry Potter fanfiction for over 20 years (!!) and started writing in 2020. I find myself drawn to writing messy, dark, political, taboo, and niche fics and whatever I feel like is missing in fandom, but my interests are very much all over the place. The Noble and Most Ancient House of Black has most of my focus. I also run @blackcestfest every other year which is returning for its third run 2025-2026.
I strive to treat other people in fandom well and fictional characters very, very poorly :)
** marks personal favorites
**Andromeda Liberata (160k+, M, Andromeda/genderbent!Ted Tonks, 3 part series)
In which Andromeda Black cruelly betrays her sisters and sets in motion the total destruction of the Noble and Most Ancient House of Black because she fell in love with a lesbian muggleborn.
(do please mind the tags, particularly sexual violence, bigotry & prejudice, suicidal ideation, and alcohol abuse/alcoholism)
Book 1: Andromeda Vincta Catenis (6th year) - 77k, Complete
Book 2: Andromeda Ausa Ire (7th year) - 55k, Complete
Book 3: Andromeda In Bello (Graduation-1981) - 30k+, WIP

love handmade for someone like me with diamondmeadows (James/Sirius, 19k, E)
In November in year 13, Sirius skips James’s rugby match, and they don’t exactly fight about it.
Or - James is not gay. Sirius is a little drunk. Those facts balance each other out.
guard down for you (prongsfoot, 4k, E)
A month after their confusing encounter, James finds himself confused with Sirius. At least this time it’s just a dream. They can just say it was a dream.
I'm a self-destructive landslide if you want to be the hill (wolfstar, 5k, M)
Walburga Black is dying, and, even if he’ll admit he’s drinking a bit more than he ought to at the moment, Sirius doesn’t care at all. He does, however, need to apologize to Remus.
By the end of the night, he owes a few more apologies.
Copying Wandwork (1.5k, E, wolfstar + Peter)

A Rat in the Drawing Room (1.6k, M, Peter/Regulus for @wormtailweek)
Peter’s first task for the Death Eaters is a familiar one. He has years of practice watching over self-destructive Black men.
A Marriage Declined (1k, M, Remus/Sirius)
On top of the old oak desk, next to a stack of books on unions and promissory magic, crisp white parchment announced, “An invitation to the marriage of Lord Sirius Black to Lady Narcissa Black.” One drop of blood stained the white of the parchment, plotting out the “N” of Narcissa, two on the oak of the table, and then countless more on the rug.
**Alphard’s Favourite (5k, M, Peter/Sirius, past Alphard/Sirius, @blackcestfest)
Peter tries to find out why Sirius is so upset over Alphard’s inheritance. Then he tries to make sure Sirius doesn’t fall off the roof. Then he tries to ensure Remus doesn’t hear them.
Till Tomorrow and Till Death (11k, E, Regulus/Remus for @hprarepairfest)

Eight years after Voldemort’s defeat, as the illegal potions trade ravages England and the government intensifies lycanthropic restrictions in response, Fleur and Tonks join forces to uncover corruption in the Ministry.
As they discover a scandal deeper than they could imagine, Fleur contends with her complex legal status, Tonks contends with her mother, and they do their best to avoid contending with their feelings for each other.
**Icarus (20k, M, Pansy/Parvati/Millicent for HP Triad Fest)
A year after the war, Parvati runs into Pansy and Millicent at a club in Ibiza and finds herself embedded in their debauchery. None of it’s healthy, and it works until it doesn’t.
Icarus Before the Fall (2k, M, Pansy/Millicent)
August after the Battle of Hogwarts, as most of the Slytherins gather together in the Nott Castle, trying to find ways to forget, Millicent worries about Pansy’s new liquid love.
A prequel, unfortunately, as much as Millicent attempts to convince herself otherwise.
if you built yourself a myth (7.5k, E, Dorcas/Narcissa for Rare Pair Fest)

Only One Bed at the Three Broomsticks
(2k, M, Andromeda/Augusta for Sapphic Bingo)

**Acting Out (2k, M, Molly/Narcissa for shipuary/kinkuary)
Narcissa’s to-do list for the evening: -Drink enough champagne she forgets she ever had more than one sister. -Make someone cry. (Does not count if it’s herself.) -Be told she is the most beautiful woman at the party. (Preferably by multiple people.) -Have sex that would scandalise her parents. (If they would even pay attention.)
Two Quaffles Pub (9k, M, Cho/Ginny for @hpqueerfest)

In order to protect Lily from the Death Eaters, Narcissa offers her a version of kindness.
Like Fiendfyre (1.5k, T, Hermione/Pansy for @careofmagicalshippers Fall Fest)
"She apologizes, and maybe it’s the shock that Pansy Parkinson actually apologized for something (as if Pansy had done anything other than apologize for her existence for the past five years), she agrees, and Pansy is frightened by the thrill of hearing Hermione Granger say yes."
Blackcest:
Mirror (I'd want to fuck me too) (Sirius/Fanon Sirius selfcest, 5k, E)
In 1999, Sirius returns through the Veil. Unfortunately, another Sirius also comes through the Veil.

sunlight, held together by water with @blackstarkink (Draco/Regulus, 10k, E)
Hidden away in a small French town, Regulus has survived in secret for decades on a diet of mostly wine. Two years after the war, Draco goes to visit his newly revealed cousin, and, while the conversation is excellent, Draco’s favourite part is what happens after Regulus passes out.
insatiable since I tasted you (Draco/Regulus, 6k, E) with @blackstarkink
Regulus invites Draco for a particularly indulgent tea at Grimmauld Place, and their ambiguous, drunken flirtation from the summer escalates quickly.
a lesson in manners with @diamondmeadow (Sirius/Draco, 7k, E)
Despite the very clear wishes of the master of the house, Grimmauld Place keeps letting Draco inside. It doesn’t help that Harry keeps inviting him over too. It certainly doesn’t help that Draco and his godson have… something going on. Sirius needs to teach him some manners.
house discipline with @diamondmeadow (Sirius/Draco, 11k, E)
Draco arrives at Grimmauld Place with a copy of ‘Warming Charms for the Wintering Wizard’ and a plan for getting what he wants out of Sirius Black for a second time.
Folgers Coffee, Black (modern Blackcest series)
**Merry Christmas, Please Don’t Call (25k, E, Sirius/Regulus)
The Black family has plenty of secrets, and Sirius has his own – like how he really got the concussion derailing his fall semester at Hogwarts University. When Regulus surprises him on campus during winter break and a sudden snow storm forces him to stay for Christmas, the secrets Sirius has been hiding from himself are revealed.
Oh Golden Boy, Don't Act Like You Were Kind (9k, E, Sirius/Regulus/James)
James walks in on Sirius and Regulus. Sirius knows this could go very, very badly or be the best Christmas present he has ever received.
Running Through the Halls of Your Haunted Home (10k, E, Andromeda/Bellatrix & Andromeda/Ted)
When Bellatrix shows up at her door with an invitation to Narcissa’s wedding, Andromeda does not shut it in her face. She does not kick her out of her house. She does, eventually, tell her no, though it comes a little too late.
Would Rather Burn Forever (Sirius/Regulus/James, 10k, E)
James is getting married, and Sirius is not sad about it. Drunk at his bachelor party, James suggests one last night between the three of them, and Sirius and Regulus jump at the opportunity and take things much farther than James may remember. (or, what may be a tipping point in a corruption arc)
what if he's written "Mine" on my upper thigh only in my mind? (1k, E, Sirius/Regulus) for @torturedpoetsflashfest

Bellatrix Black Lestrange was survived by her husband, sister, nephew, and me, whatever I could be considered, if I could even be considered someone who survived her.
**Nymphadora, Nymphet (20k, M, Bellatrix/Tonks) for @womenofthehouseofblack
Dear Nymphadora, I’ve been informed of a temporary Defence professor this year, and you may have gathered she is (was) my sister. Be careful. If she attempts to harm you in any way, report straight to Professor Sprout. We shall talk more at Christmas; it may be time for you to learn more about my side of the family. Please watch your potions work – I know you can do better than last year. -Mum
A Swan’s Son (Or, Caring for Bellatrix) (7.5k, E, Bellatrix/Cygnus, Bellatrix/Andromeda, Bellatrix/Sirius) for @hpcestfest
Cygnus will have a son - even if it means killing his wife and dosing his daughter with arousal and fertility potions until she gives him one. But an inclination towards murder and incest runs in the Black family, and Cygnus isn’t the only one with ideas.
