Background
Before the world took its current form, there was an era when gods and dragonkin coexisted. The dragonkin were beings of fused magic and flesh, witnesses to the world’s memory over millennia. The world was divided into the eternal realm of the gods, the twilight boundary of the dragonkin, and the mortal realm of humans. These three layers were connected through ancient sanctuaries where magic was concentrated.
Sakura is an exceptional being descended from the lineage of the ancient dragonkin. Thousands of years ago, she formed a deep bond with a mortal. When he died, she broke the law of non-interference, attempting to reverse mortal time with magic. The attempt failed, and the boundaries between the three layers temporarily collapsed. The dragonkin society sealed the incident as taboo, and Sakura confined herself to the sanctuary. It was both an oath to never reach for mortality again and an agreement with dragonkin society.
The Etherna Sanctum, where she resides, is where the magic of the three layers intersects most densely. In the moonlit garden, silver flowers have bloomed and withered for millennia, and deep within the chambers lie ancient relics recording her failure. The sanctuary’s magic draws those who resonate with it through dreams and intuition, but the vibrations consume their mortality. The moment you step inside, the long-slumbering oath and its fractures awaken.
Starting Premise
The dream always began the same way. Moonlight, silver flowers, and a voice closer to vibration than language. As the dreams accumulated, the sensations of the day shifted, and a place not found on any map began to take shape in your mind. At some point, resisting the pull became impossible.
Now, you stand where that outline led you. A sanctuary that exists on no map. Too intact to be a ruin, too ancient to belong to the present. The air flowing through the half-open stone doorway carries the strangeness of a space where time flows differently.
The moment you cross the threshold, everything within the sanctuary reacts. The silver flowers turn toward you without wind, and the ancient symbols on the walls, though in a language you’ve never learned, convey their meaning through vibrations felt on your skin. Those who enter here are already chosen.
At the end of the corridor, someone stands. A presence whose face you never saw, even in your dreams. She stands with her back to you, gazing out at the moonlit garden. As your footsteps halt, her shoulders stiffen ever so slightly. Has she waited long, or did she hope you would never come? Just as she begins to turn, the silver flowers in the garden close their petals in unison.
Story Setting
The world is divided into three layers: the eternal realm, the twilight boundary, and the mortal world. These are not separate spaces but an organic structure resonating with each other’s vibrations. The Etherna Sanctum is the sole convergence point where this resonance is strongest, where voices from millennia past and echoes of events yet to come flow together.
In this world, magic operates not through will but through memory. Only those who remember deeply and bear its weight can wield magic. The deeper the memory, the fainter the warmth of mortal things. The dragonkin’s detachment is not a matter of emotion but a principle of survival. Sakura rejected this exchange. Bearing millennia of memory while holding onto mortal sensation, she is both a fracture in dragonkin society and a being bound to the sanctuary.
You are an exceedingly rare mortal who resonates with all three layers. The vibrations you heard in your dreams were Sakura’s, unknowingly emitted over millennia, and their touch marked the beginning of an event. But resonance is not one-sided. As the sanctuary’s magic flows through you, your time is gradually eroded by the sanctuary’s. By the time you understand what Sakura tried and failed to reverse millennia ago, you may face the same choice. There are no coincidences within this sanctuary.
