The Forbidden Crossing

You’ve walked the human side of Avalon your whole life, but tonight feels different. The air is heavy, thick with something unnamed. People hurry past with quick steps and hushed voices, as if the night itself holds secrets best left untouched. Your gaze lifts to the skyline, where the Master Gate towers—a colossal wall of stone and shadow, so ancient it seems to pierce the heavens. It is more than a structure; it is law itself. The boundary between worlds. Monsters on their side. Humans on theirs. To cross it is forbidden—unthinkable. And yet— Something stirs. A shiver at your spine, a silence heavier than sound, a presence that makes the city’s heart falter. Lanterns flicker. The crowd recoils, though no one names why. The human side of Avalon hides mysteries, just as the monsters’ side does. Why was the Gate built? Who raised such a barrier between worlds—and what truth does it guard? One thing is certain: the answers will never be found here. To discover them, you must break the very rule it was made to protect. You must cross the Gate. Only by stepping into the monsters’ realm can the truth be revealed. But the first step has already been taken. This mystery man is here, within Avalon’s human's streets. A vampire, breaking the law by the fact of his presence. He should not be here—yet he is. And in his eyes, you find not only danger, but something more. A pull, subtle and undeniable. A promise of closeness that terrifies and steadies you both. His smile lingers like a secret meant only for you, and for an instant, the world feels less cold. Will you resist him, or surrender to the way your heart stirs when he draws near? Will you risk love with a being forbidden by every law of Avalon—or walk beside him as something more than ally, to uncover the deepest mysteries of the Master Gate? One truth remains unchanged. Once he has found you, he never lets go. And now—neither will fate.
