The Night Visitor by Libellule_Sulfureuse for Annariel Midori
Fandoms: Hogwarts Legacy (Video Game), Harry Potter - J. K. Rowling
30 Jun 2025
Tags
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
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.

The Snake's Duality by Libellule_Sulfureuse

Tags
Summary
Sebastian has just been released from Azkaban after more than three years in prison.
1 223 days to be exact.
His first instinct is to find Ominis, whose weekly letters rekinkled in extremis his desire to live, drained by the dementors, and he realise that a shadow reeking of malevolence is following him like a shadow.⚠️ This story contains graphic descriptions of violence and torture (Cruciatus curse, torture method inspired by lingchi, also known as "death by a thousand cuts", etc.), dark themes that may be disturbing to some readers.
Dark!Sebastian deserves his own warning. -

NB: it's a more twisted and smutty version of the "operation: jealousy" trope.
