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.

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
