Summary
When Sophie Mason is told she can wield an ancient power, she does what seems obvious to her: master it and use it for good. The problem is that no one will tell her how.
Alongside Sebastian Sallow and Ominis Gaunt, Sophie navigates power, responsibility, and the danger of institutions that demand action while withholding understanding. Sophie questions the Keepers, interrogates the narrative of “evil goblins,” grounds ancient magic in hermetic and alchemical logic, and asks the question the game keeps circling but never answers: when is the use of power justified — and who gets to decide?
Come for the Sebastian/Ominis/MC polycule and illustrations.
Stay for radical goblin union organizing, ancient magic that actually makes sense, and a protagonist who refuses to accept silence as wisdom (and the polycule). -

Summary
Fresh from a summer of bomb shelters and blackout curtains, Tom Riddle comes back to Hogwarts determined to master the future itself. Yet when mirrors start shifting, whispering, and revealing a version of him he never meant to become, he’s forced to question whether the future he seeks is a prophecy… or a warning.

Summary
In the not-so-distant future, Death Eaters have retaken power in England and want to resurrect Lord Voldemort. Fifty-year-old Hermione Granger decides to take matters into her own hands and go back in time to adopt and raise Tom Riddle. She did her research. She has an evidence-backed plan.
She did not mean to bring Harry Potter along.
Forced to pretend to be married, they now find themselves raising a six-year-old future Dark Lord in the shadow of Gellert Grindelwald’s growing influence, and discovering that changing history is far messier than anticipated.
Expect a Spy Family-esque, crack-adjacent fic with fewer pink bubble-gum telepaths and more haunted Victorian orphan magical prodigies; Hermione leading an aggressively early crusade for Muggle education reform; and a fifty-year-old Dumbledore pining helplessly for a fifty-year-old time-travelling Master of Death Harry Evans.
Featuring Harry/Hermione “widower” romance, one-sided Dumbledore/Harry pining, and baby Tom Riddle being, generally speaking, a very good little menace.

Summary
They were dead, all of them. His wife. His baby girl. His brother, his sisters, his nieces and nephews. Everyone he had called friend. Their bodies were still rotting in the rubble heap of Shambala, somewhere above him now. Duris only hoped that he had completed the ritual correctly. He didn’t fully understand the magic he was using. Only that it had the power to to turn back history… to change the flow of time… that was the only thing he needed… the last hope of a destroyed people… that history could be changed…that things might be different…
“Open… the dragon’s door… Zahras…” his raspy voice echoed through the darkness. “... return to us.”

Summary
"If you had the chance to go back fifty years in the past would you take it?"
Wyatt Whittermore wonders how he lost his brother to propoganda, his parents to his brother, and his country to Death Eaters. Death Eaters!
And how was it that some of the very people who had fought this before, the ones who had taught them the history — the ones he expected to know better — were the ones who had allowed it to happen?
Hadn't they all collectively learned this was wrong decades ago, when Harry Potter defeated Voldemort?
A year ago, he’d have thought it was absurd. Impossible. And yet, as the world ended, the question was offered:
"If you had the chance to go back fifty years in the past would you take it?"How might the timeline change?
If nothing else, Draco Malfoy is going to find out how. -

Summary
Before the fall, the Dark Urge is pure instinct — an unfallen creature of blood and hunger, not evil in the moral sense, but innocent of choice. Violence is his Eden, murder his nature.
Then she arrives — light, warmth, consciousness. Like Eve reaching for the apple, she awakens awareness. And awareness is the first exile.Y'all I just wanted to write a Quentin Tarantino-level gore Baldur's Gate 3 Dark Urge fanfic but 14k words in and now I'm like wading into moral philosophy and exploring my own understanding of spirituality, objective morality, and the soul.
You know. Just normal Baldur's Gate things.

Summary
The new Honmoon was supposed to keep the demons out.
Or did it?
A sequel is on. Huntrix is back, but the rules have changed. New faces enter the fight, old wounds resurface, and the Saja Boys launch the comeback tour no one asked for — except Gwi Ma.This fic is a longform "sequel" to the movie. It expands on the Honmoon, Mira and Zoey, and the Saja Boys’ stories, with ‘new song’ lyrics and new side characters.
Quick hiatus bc I have too many projects. Comment if you want more tho, and I'll reprioritize. -
