A dark reimagining of Hogwarts Legacy, nothing is about magic, but with lots of adult contents, enjoy.

Summary
The agent from America that's been sent to assist the British Ministry of Magic in a snallygaster smuggling case is one of the most detestable characters that esteemed Wizengamot member Ominis Gaunt has ever had the misfortune to meet. She's loud, crude, and frequently enters his office to scream at him for doing his job without any kind of fear of him.
He begins to rather unfortunately fall in love with her because of this.

Summary
Sebastian has convinced his two friends to enter Slytherin's Scriptorium, and has taken the book with him, determined to find a cure for Anne. Delphine and Ominis find themselves working together to disrupt Sebastian's plans, trying desperately to stop him following a dark magical path that they can never return from.
But they have their own problems to contend with.
Delphine is traumatised by the events of her fifth year. Losing her mentor and the guilt that plagues her every waking moment.
Ominis has lived his entire life resisting the pull of dark magic, constantly repelling its tormenting allure.
And the biggest temptation they face is each other. Delphine longs to surrender the control and responsibility that's been thrust upon her, and Ominis' raw power draws her in like nothing she's ever felt before. Ominis is sure that Delphine is bringing out the worst in him, as his dreams are filled with images of holding her down and making her beg for him.
They can't give in to their desire, not when Sebastian's path is leading him further and further astray, and they might be the only ones who can pull him back.

When Marvolo strongarms him into attending another Pureblood's stag party, Ominis runs into the last person he would ever want to find working at a Burlesque Theater.

Summary
When Ominis begins to dream of lives vastly different from the one he leads in the present, something shifts in the fabric of time and space.
Questions arise. What is happening to him? Who or what exactly is he? What is real, and what isn’t? Can mere dreams hold such formidable power over everything he thought he knew, feared and loved?

The Night Visitor by Libellule_Sulfureuse for Annariel Midori

Summary
Ominis has nothing human left in him. All that remains is that glacial hunger which drives him, night after night, to feed on the ecstasy of women with virgin bodies and minds infested with unspeakable fantasies.
☆☆☆☆☆
This OS is a deliberately dark and smutty reinterpretation of the Zburătorul, a supernatural being from Romanian folklore, often likened to an incubus. He visits young women in their sleep, seduces or torments them sexually, causing a sickly languor, a gradual wasting away, and a consuming sexual obsession.

Summary
Twelve years ago, Sebastian Sallow was betrayed by those he trusted most and sentenced to Azkaban. Now free, he returns to a world that feels foreign, only to find Ominis Gaunt unrecognizable, molded into a shadowy enforcer of his family’s dark legacy.
Both men have been shaped by betrayal and survival, their bond fractured and buried beneath layers of guilt and resentment. As their paths cross once more, the ghosts of their past rise to suffocate them, forcing them to confront the men they’ve become and the darkness they can no longer outrun.

Summary
Even though Ominis grew up with his family at the manor, always surrounded by people, he often felt lonely and isolated. That all changed the day he met you. But now that he has got you, he finds it difficult to control his fear of losing you. Well, in all honesty, he doesn't even try to control it - he just curses anyone who dares go near you. But now you've simply had enough, and decide to teach him a lesson.
The method? Not granting him release until he proves he can control his actions. -

Summary
She didn’t think her birthday mattered. He took it as a personal offence. So no cake, no candles. Just Ominis, velvet, and a few bites from a serpent that’s anything but natural. Happy birthday, Evelyne!
⚠️: Use of a magical serpent in an erotic, and symbolic context;
A_N: This OS was published on 25 November 2024 before being made private 3 days later. In fact, I realised too late that I wasn't happy with it. So I reworked it. I hope you like it.

What started as a delightful morning, led to the discovery of an illegal poaching operation. It should've been business like usual. However this time, Ominis has a vested interest and you cannot help but oblige.
Between sensual touches and the impending danger of poachers with volatile magical creatures. You both must crack down the black market business before it gets out of hand. Delving into the depths of corruption and greed under the sea. (Heh, a pun!)
