Along the inner wall, a hundred niches hold objects of ambiguous purpose: a bell that rings only when held by someone lying, a pair of spectacles that show memories instead of the present, a dried octopus preserved in a crystal sphere. Each object was left here by a previous occupant of the upper floor. None of them are labeled. Curators long ago gave up trying to catalog them, concluding that the upper floor chooses what to reveal to whom. Beyond the gallery, a short corridor slopes subtly downward — disorienting, because you know you are still on the upper floor. The study is a circular room with a domed ceiling painted to resemble the inside of a skull. A single desk dominates the center, carved from petrified wood. On it: an inkwell that never empties, a quill that writes in whatever language the user thinks in, and a half-finished letter dated “the day after tomorrow.”
Those who spend a full night in the observatory report strange effects: their watches run backward, their hair grows an inch, and they remember dreams they haven’t had yet. Some refuse to leave. Those who do leave can never find the upper floor again, even if they return to Yhivi. None of this is accessible without permission. A single door at the top of the spiral stair is guarded by no lock, no key, no guard — only a small brass plaque that reads: The upper floor of Yhivi is not a place. It is a state of having forgotten what you came for. If you remember your purpose, turn back. If you have already forgotten, enter, and be welcome. Thus, the upper floor is less a physical space and more a riddle. It holds the archives of decisions never made, the echoes of conversations that healed or ruined, and the scent of that extinct jasmine — which, if you breathe it long enough, makes you forget your own name, but remember everyone else’s.

Halfway up, the air changes. It grows cooler, drier, and carries the faint scent of old paper, metal dust, and something floral — extinct jasmine, if the old texts are to be believed. The upper floor unfurls first as a long gallery, its ceiling lost in shadow. No windows face outward; instead, the outer wall is a single pane of smoked obsidian, polished to a mirror finish on the inside. By day, visitors see only themselves. By night, if the moon is right, the obsidian turns translucent and reveals a sky that does not exist anywhere else in the world — stars in impossible constellations, and sometimes a second, smaller moon. Along the inner wall, a hundred niches hold
Whoever lives on the upper floor of Yhivi uses this study. But no one has seen the current resident in seventy years. Letters left on the desk vanish overnight; new ones appear in their place, written in a looping, impatient hand, answering questions no one asked. The final chamber of the upper floor is an observatory, though its roof does not open to the sky. Instead, a massive bronze orrery hangs from the ceiling, its planets and gears moving to the rhythm of a world that is almost this one. In the center of the floor, a telescope points not up but down — through a shaft that plunges through the lower floors of Yhivi, through bedrock, into a cavern where a sleeping creature’s breath creates the tides.
