The Infernal Grimoire: Dominion of the Ars Goetia (Octavia X Male Reader)

Version 2 (Extended and improved!)

Title: Dominic's Descent: Chronicles of the Ars GoetiaPart 1: The Mansion of Secrets

Scene Setting & Exploration
We begin with Dominic as an engineering student who spends most of his time on construction sites, fascinated by ancient architecture and forgotten buildings. One of his latest projects takes him to an old, decaying mansion on the outskirts of town, a place long shrouded in rumors of hauntings and hidden treasures. The local townspeople talk about the mansion as if it has a dark history, which piques Dominic's curiosity.

While doing a routine inspection before the demolition, Dominic can't shake the feeling that the mansion holds secrets. During his exploration, he stumbles upon a dusty, forgotten hallway with a large painting of what looks like an upside-down depiction of heaven and hell. The detail in the painting is unsettling—the angels' wings are blackened, and demons crawl upwards toward a light.

Feeling the weight of the painting, Dominic touches it, and the wall behind it gives way slightly. After flipping the painting to its rightful position, a hidden compartment reveals itself, housing a grimoire wrapped in old, cracked leather.

Dominic examines the book, intrigued by the complex symbols on the cover and the aura of mystery it radiates. Despite a slight sense of unease, he decides to take the book with him, thinking it might be valuable or at least interesting to study.

Obsession Begins

Dominic's Academic & Social Life Unraveling
Once Dominic returns to his apartment, the allure of the grimoire grows stronger. At first, it seems like nothing more than an ancient relic, filled with Latin phrases and strange symbols, but Dominic's academic background and keen intellect make him eager to decipher its contents. He begins to study the language, initially using resources from the university library. His professors notice his growing obsession with ancient texts, but Dominic brushes off their concerns, assuring them it's just a hobby.

The more time he spends with the grimoire, the more his regular life starts to unravel. His university assignments are left unfinished. His friends grow concerned about his increasingly erratic behavior, but Dominic dismisses their worries. His world begins to narrow, focusing only on the ancient symbols that dance through his mind, haunting his dreams. He isolates himself, pouring over the pages late into the night, becoming more fluent in the book's language.

As the months pass, Dominic begins to understand the true nature of the grimoire—it's not just a historical artifact but a manual for dark magic. The runes described within are far more than academic—they have real-world power. Dominic experiments by carving small runes into his skin. At first, the effects are subtle: heightened senses, increased stamina, sharper instincts. But soon, the power grows more dangerous. He heals quicker, moves faster, thinks more clearly. The more runes he adds, the more powerful he becomes—and the deeper he's pulled into the grimoire's influence.

Internal Conflict and First Manifestations of Power
As Dominic's power grows, so does his internal conflict. His mind is at war with itself: part of him knows that the path he's walking is dangerous, but the thrill of power is intoxicating. His reflection begins to change; his eyes darken, his skin seems to shift ever so slightly under the weight of the runes. Dominic feels like he's becoming something else.

One day, he notices an inscription at the back of the grimoire that speaks of opening portals to other realms. This ritual, unlike the others, requires a sacrifice. Dominic's moral compass wavers, but curiosity wins out over his hesitation. The darkness calls to him, and he can't resist answering.

The Ritual of Blood

The Criminal's Fate
Dominic spends weeks planning his next move. The book demands a human sacrifice, and Dominic's conscience fights back for a time. But he rationalizes that if he chooses someone who "deserves" to die, it wouldn't be wrong. After a few sleepless nights of guilt and moral deliberation, he settles on a known criminal—a murderer whose actions have hurt countless people.
