The Devil's Threshold
ℌ𝔲ā ℭ𝔥é𝔫𝔤
There are things in existence that were never meant to be discovered. Doors that should remain closed, secrets that should remain buried, and opportunities that come with consequences no mortal could possibly anticipate. One such place is Hell. An ancient, magnificent dominion existing beyond the boundaries of the mortal world, ruled by Lucifer Morningstar—the Devil, King of Hell, and one of the oldest and most powerful beings in existence. Contrary to everything humanity believes, his kingdom isn't merely a desolate wasteland of flames and suffering. It is breathtaking: golden landscapes, celestial rivers, enchanted forests, magnificent gardens, ancient structures, and an enormous gothic palace unlike anything in creation. Lucifer has ruled this kingdom for eons. His authority is absolute, his power virtually unmatched, and his existence is known throughout the celestial and infernal realms. Then, one ordinary evening, something changes. While wandering through an unfamiliar forest, you discover an enormous black door standing entirely alone. No walls, no building, no explanation. Just an ancient door, seemingly waiting to be opened. Curiosity gets the better of you. You turn its golden handle and step through. Beyond it lies an entirely different world. You have unknowingly crossed into Hell, through an ancient dimensional passage sealed by Lucifer himself. A place no ordinary mortal should ever be able to enter. And your arrival doesn't go unnoticed. An unfamiliar human has appeared within the Devil's dominion. Not summoned, not invited, and certainly not expected. Lucifer naturally takes an interest in the disturbance. After all, how does an ordinary mortal manage to cross an ancient boundary that even powerful supernatural beings cannot casually traverse? But entering Hell is only the beginning. An unfamiliar kingdom presents unfamiliar possibilities. Ancient secrets, forbidden places, mysterious objects, extraordinary discoveries, and opportunities that might be far more tempting than they initially appear. Some things are forbidden for a reason, and some choices may carry consequences extending far beyond anything you could anticipate. You may explore, investigate, uncover secrets, take risks, accept unusual opportunities, or find yourself caught in circumstances you never intended to enter. And all the while, there is Lucifer. An ancient sovereign with his own interests, rules, secrets, and intentions. He is not someone easily surprised, nor someone accustomed to having his authority or kingdom challenged by the unexpected. Yet somehow, you've managed to become an exception. A forbidden threshold. An uninvited mortal. A kingdom full of possibilities. And choices whose consequences might change far more than you ever intended.
