The Aperture in the Hollow

Dr. Fiona MacLeod arrived at the Black Isle in late autumn, hired by Historic Environment Scotland to document a cluster of previously unrecorded standing stones near the Beauly Firth.
The site was unmarked on any OS map: nine weathered monoliths arranged in a rough oval on a peat bog that locals called “the Hollow.” Folklore spoke of it as a place where sheep refused to graze and compasses spun lazily. Fiona dismissed it as superstition. She was thirty-eight, tenured at Aberdeen, and believed in measurable data.

Her first drone survey revealed nothing unusual. The stones were Neolithic, perhaps 4,500 years old, aligned roughly to the midwinter sunrise. But on the second pass the footage glitched: for exactly 7.2 seconds the stones appeared to multiply—twenty-seven instead of nine—before snapping back. She blamed atmospheric interference.

That night in the bothy she had rented (a stone box with a tin roof, no electricity, one oil lamp), she reviewed the raw files on her laptop. The glitch repeated, but slower. The extra stones were not duplicates; they were offsets, existing at slight angles that should have overlapped but did not. The geometry was wrong.

Not wrong in alignment—wrong in dimensionality.

She wrote in her field notebook:

22:47 – Stones exhibit apparent hyper-dimensional projection during low-light imaging. Likely lens artifact or peat gas refraction. Tomorrow: ground survey with total station.

She did not sleep well. The wind sounded like breathing through too many mouths.

Section II: The Hollow Opens

By midday the next day the peat had softened under unseasonal rain. Fiona set up her theodolite amid the stones. The instrument refused to level; the bubble wandered as though gravity were directional here, pulling sideways.

She began measuring angles.
The first reading: 137.4 degrees between stone 3 and stone 7. Reasonable.
The second: the same pair now read 137.4 degrees… but inverted, as though measured from the other side of a surface that did not exist. She recalibrated. The instrument gave 137.4 again—then 222.6, which was 360 minus 137.4 but folded inward. She sketched it: a circle collapsing through its own center into a negative space.

The stones began to hum.
Not sound—vibration felt in the marrow. Low frequency, like distant machinery, but no machinery existed for miles. Fiona’s phone died despite full charge. The drone refused to power on. She felt watched, not by eyes, but by the absence between the stones: voids arranged in logarithmic progression, each gap deeper than the last.

She stepped into the center of the oval.
The peat gave slightly, like walking on skin. Then the ground dropped—not fell, refracted. She found herself standing on the same spot but beneath it, looking up through the bog as though it were glass.

Above her the stones loomed larger, their shadows stretching in directions that ignored the sun. And between them moved shapes: slow rotations of absence, spirals of nothing that pulled light inward without reflecting it.

One shape paused.
It regarded her with the patience of erosion given intent. Fiona understood then that the stones were not markers. They were teeth. The Hollow was a mouth that had waited since the last ice age for something warm-blooded to step inside and remind it what hunger felt like.

She did not run.
Her legs simply forgot how to believe in forward motion.

Section III: The Survey That Never Ended

The search party found the bothy three days later.
Door ajar, laptop open on the table, screen frozen on the last drone frame…

Nine stones, twenty-seven shadows, and one small figure in the center looking directly at the camera—or through it. Fiona’s field notebook lay beside it, pages filled with measurements that began in standard notation and devolved into tight spirals, then single looping lines without end. The final entry, timestamped 14:03 the day she vanished:

It is not a site.
It is an aperture.
We were never mapping it.
It was mapping us back.

No footprints led away. The peat around the stones was undisturbed except for one perfect circle where the grass had withered in a logarithmic pattern. Locals reported the aurora that week had been wrong—ribbons of green folding inward upon themselves, forming doorways that opened onto peat-dark nothing.

The stones remain.
Historic Environment Scotland closed the file as “unresolved anomaly.” Drones sent since return footage with extra stones that disappear on review. Surveyors who approach at dusk feel the vibration first in their teeth.

Somewhere in the Hollow, between angles that should not meet, something patient completes another measurement.

It has adjusted its regard by the smallest increment.

The aperture remembers our shape now.

We were only the brief warmth that allowed it to taste dimension again.
