The Lantern of Persistent Motion

Marta and I had just settled into our new apartment above a shuttered cannery in the small coastal town of Dunmore. The place was a relic, with peeling paint and a view that stretched across gray rooftops to the restless Atlantic. That evening, we were washing the last of the dinner dishes, the clatter of plates the only sound besides the distant groan of the tide. Our daughter had finally fallen asleep in the cramped bedroom, lulled by the salt air and the steady blink of the lighthouse miles out at sea.

As I wiped a glass, I noticed a light out of the window. It was about four houses down, hovering over the flat, tarred roof of the old Harlow fish-smoking shed. The light was a soft, milky orb, pulsing gently, as if it were breathing. It began to circle the roof—a slow, deliberate loop, like a satellite tracing its orbit. Sometimes it would pause, bob slightly, then resume its endless circuit. I set the glass down and tapped Marta’s arm.

‘Look at that,’ I said, pointing with the towel. Marta squinted, dried her hands, and came to stand beside me. For a long moment, we just watched. The light never changed its pattern—always circling, always the same radius, as if tethered to some invisible center. It was too low and too steady to be a drone, and there were no boats nearby that could cast such a light. I felt a cold knot tighten in my stomach.

‘We should check if it’s something from outside,’ Marta said, already reaching for her coat. I grabbed my jacket, and we hurried down the creaking stairs, out into the damp, salt-laden air. The street was empty, the only sound the crash of waves against the breakwater. We walked to the corner, our breath fogging, and looked up at the shed. Nothing. No spotlight, no construction light, no car with its high beams on. The roof was bare, just wet tar and seagull droppings. But we could still see the orb from this new angle, hovering and circling, impervious to our scrutiny.

We returned to the apartment, our hearts thumping. From our window, the light continued its monotonous dance. Hours passed. The kids woke for water, and we shushed them back to sleep. At midnight, the orb was still there. At three in the morning, it hadn’t stopped. Marta suggested it might be a reflection, maybe from the lighthouse, but the lighthouse beam was white and sweeping, not a contained circle. We tried every rational explanation, but each one crumbled under scrutiny.

Then, without warning, the light stopped. It hung still for a second, then descended, slowly, behind the roof. We held our breath, waiting for it to reappear, but it didn’t. The night was dark again. The rest of the morning passed in an uneasy silence. When dawn broke, the first gray light revealed something new on that roof: a small, circular stain, like a burn mark, perfectly centered where the light had last hovered.

The next evening, as we did the dishes, I couldn’t resist glancing at the roof. The stain was still there, but it seemed larger, darker, almost wet. Marta saw it too. ‘It’s spreading,’ she whispered. We watched as the dark patch grew, inch by inch, until by midnight it had engulfed the entire roof. And then, from the center of that black expanse, the light returned. But this time, it circled not the roof, but the stain itself, as if feeding it.

Over the following week, the stain began to creep down the sides of the building, reaching the windows, turning the glass opaque. Our neighbors, the few who remained, started leaving without explanation. The Harlow shed stood like a monument to something we couldn’t name. One night, the light left the roof and drifted toward our window. We watched, paralyzed, as it hovered just a few feet away. It was close enough that I could see it was not a solid sphere, but a churning mass of tiny, writhing shapes—like maggots made of light.

That was the night the kids started sleepwalking. We’d find them in the kitchen, staring out the window, their small hands pressed against the glass, whispering ‘it wants to come home.’ We tried to leave, but every road out of Dunmore was blocked by fog so thick you couldn’t see your own hand. On the third night, the light pressed against our window, and the glass began to crack, not with force, but with age, as if years were passing in seconds. I knew then we were part of something vast and ancient, a pattern that had been repeating for longer than the town had existed.

The next day, I found an old journal in the building’s basement, written by a fisherman from the 1920s. He described the same light—what he called ‘the persistent orb’—and said that whenever it settled on a roof, the building would ‘sink into the earth, slowly, and the ocean would reclaim it.’ He wrote that it was not a ghost or a spirit, but a kind of beacon, calling something from the deep. The journal ended with a sketch: a spiral, and the words ‘we are its orbit.’

Now, as I write this, the light has circled our apartment for the fifth night. The stain has crept through the walls, and the air is thick with the smell of brine and rot. Our daughter no longer speaks, but she hums a tune I’ve never heard, one that matches the rhythm of the orb’s flight. I look at the window, and I see our reflection—but in the reflection, there is no room behind us, only an endless dark sea. We are no longer watching the light from the outside. We have become the point around which it circles, and I fear we will circle here forever, tethered to a rooftop that no longer exists, as the world forgets us.
