The Unyielding Ravenclaw of Birmingham by sunkissedtrampolin3

CURRENTLY BEING REWRITTEN. She's a Shelby. Trouble runs in her blood. Dragged from Birmingham to Hogwarts, Larissa Shelby carries more than her family's notorious name-she carries ancient magic the wizarding world thought was long buried. But Hogwarts is not all as it seems. Curses whisper through the shadows, relics hunger for blood, and every choice drags her closer to the edge. Enter Sebastian Sallow: clever, infuriating, impossible to ignore. He's as reckless as she is sharp-tongued, and together with Ominis Gaunt, they're pulled into a spiral of secrets Hogwarts was never meant to reveal. As Larissa flirts with power-and danger-she has to ask herself: is she carving her own path, or stepping into the darkness her family was born to rule? Because at Hogwarts, survival isn't about following the rules. It's about rewriting them. Trigger Warnings: Dark and mature themes Sexual content (characters aged 18+) Graphic descriptions of death Violence and physical harm

No Choice But You // Ominis Gaunt x Reader by c0nfring0

HOGWARTS LEGACY SPOILERS AHEAD!! Ominis x Reader fanfiction is based in their seventh year. All characters have been aged up to 18 years of age where explicit content is involved. Written from the perspective of fem Slytherin y/n. ---------- Sebastian has been sent to Azkaban. Of course, Ominis blames you--it's only natural after everything that happened in your fifth year. For the entirety of your sixth year, Sebastian was at Azkaban. While Ominis understood that it was a necessary action to take considering what Sebastian did, he didn't forget that you encouraged it, or that you partook in the dark arts yourself. It was against everything he stood for. He warned you every step of the way, and neither you nor Sebastian listened to his warnings. By a stroke of luck, the ministry has decided to give Sebastian a second chance. He gets to come back to Hogwarts for his seventh year of schooling. Ominis is still Sebastian's friend, but he wants to keep you away from him at all costs. He hates you for what you did to his best friend. On a happy note, St. Mungos finally found a cure for Anne Sallow's curse, and she's back at Hogwarts for her seventh year as well. Your friendship with her blossoms, and makes it even harder for Ominis to stay away from you. Even though he hates you, he can't deny the attraction between the two of you. Everything changed one night at a party in the Slytherin common room when you two come in close contact. But can he fight his feelings and stay away from you? ---------- TRIGGER WARNINGS: Sexual Content: 5/10 Mental Illnesses: 7/10 Violence: 3/10 Self Harm: 6/10

for the hope of it all // Sebastian Sallow x reader by incendio22

''You seriously need to stop calling me your friend,'' Sebastian tells me in a low voice. ''Then what should I call you?'' I ask curiously. My stomach is fluttering like never before. ''I haven't quite figured it out just yet. But 'friend' is not it.'' He says as he squeezes my hand harder. ---- Sebastian Sallow x reader, a love story. When the summer between Y/n's 5th and 6th year at Hogwarts, she cannot stop thinking about Sebastian Sallow, despite the horrible things he did last year. She knows that what happened should have been the end of their relationship, but for some reason she does not consider it to be over. In fact, Y/n is unsure of her feelings towards him. Something about him just makes her feel like home. During their 6th year their relationship develops further, while facing new obstacles. One night Y/n discovers something that could mean the end of the wizarding world that requires help of Sebastian as well as Ominis. This is a story about love, friendship, betrayal and sacrifices. ---- Note: This takes place after the end of the game Hogwarts Legacy, but uses characters from the game. I do not own any of the characters. In this story Y/n was put in Slytherin and chose to become a keeper. This fanfiction also takes some inspiration from the Harry Potter-books, I do not own these characters either. Spoiler warning: Contains spoilers from the game Hogwarts Legacy as well as some potential spoilers from the Harry Potter-books.

Sub Rosa by moonxcandy

A story made of vows, duty, old debts, and the quiet war between mercy and guilt. In the Gaunt family, secrecy is an heirloom - and no secret stays buried for long. When they discover Dominique Novell's link to ancient magic, they decide to bind her to their bloodline. A marriage is arranged and for Dominique, the choice is no choice at all. The Gaunts hold leverage - omniscient of Sebastian's sin. To protect him, she signs her name. Now bound by law and silence, she must navigate a marriage written in clauses and consequence - one that blurs the boundary between protection and possession, mercy and guilt, duty and love. ⚠️ Content warnings and disclaimers: - this story contains spoilers for the game Hogwarts Legacy - I do not own the characters, world setting, places and names of the Hogwarts Legacy - and Wizarding World universe - chapters with explicit content will be marked with a 🌶. please consume at your own responsibility - I'm an ESL writer. I do my best proof-reading, but be prepared for possible errors.

Enjoy! SPOILER WARNING: THERE WILL BE SPOILERS FOR THE HOGWARTS LEGACY GAME THROUGHOUT ALL MATURE WARNING: THERE ARE ADULT THEMES AND CONTENT SPRINKLED THROUGHOUT ALL You have been warned ;)
