The Brass Orrery

Mara had inherited the old brass orrery from her great-uncle, a man she’d barely known but who had left her the entire contents of his cramped Victorian flat in the coastal town of Port Merrow. She’d moved in three weeks ago, hoping the change would heal the rift that had grown between her and her partner, Leo. The flat was a time capsule: dusty books, sepia photographs, and a strange, intricate orrery that sat on a mahogany table in the corner of the living room. She’d never seen anything like it. Its gears were tarnished, and the planets, made of polished obsidian, were held in delicate brass arms. It hummed faintly, even when she was sure she’d wound it down.

One evening, as the tide crashed against the seawall outside, Mara was reading in the armchair while Leo dozed on the sofa. The orrery began to emit a low, grinding sound, like stones shifting deep underground. She looked up, and the planets were moving—not in their usual slow, mechanical orbits, but jerking and snapping, as if trying to align themselves in some forbidden pattern. The central sun began to glow with a sickly, greenish light. Leo stirred but didn’t wake. Mara felt a cold draft, and the smell of brine and rotting seaweed filled the room.

She rose to investigate, and as she approached the orrery, she noticed a tiny, tarnished key lying on the floor beneath it—a key she had never seen before. She bent to pick it up, and as her fingers closed around it, the entire room seemed to lurch. The windows rattled, and the bookshelf behind her toppled, spilling volumes across the floor. Leo snapped awake, shouting her name. But Mara was transfixed. The orrery’s planets had stopped, all pointing toward a single, unmarked spot on the wall. A shadow pooled there, darker than the dim light should allow. It began to swell, taking on a vaguely humanoid shape, but with too-long limbs and a head that tilted at an unnatural angle. It didn’t have a face, but she felt its gaze fixed on her. It took a step forward, and the floorboards creaked.

Mara screamed, and the figure dissolved, leaving behind only the sound of the tide and the hum of the orrery. Leo rushed to her, but she couldn’t explain what she’d seen. The key was still in her hand, cold as ice. That night, she dreamed of the orrery. She saw a man—her great-uncle, she realized—sitting at a desk in this very room, writing furiously. He was muttering to himself about ‘the alignment’ and ‘the gate.’ In the dream, he turned to look at her, his eyes hollow, and said, ‘You must finish the circuit.’

Over the next few days, the orrery began to cast a strange influence. Leo grew irritable, snapping at her over trivial things. He started having nightmares, waking up in a cold sweat, gasping about a ‘black tide’ that swept through the streets. Mara herself felt watched, even in the bathroom, even under the covers. She tried to remove the orrery, to throw it into the sea, but every time she touched it, her hands would go numb and she’d hear a whisper, like the rustle of a drowned man’s lungs: ‘You are the key.’

One evening, while Leo was away at the local pub, she decided to examine the orrery more closely. She turned the key in a small, hidden keyhole she’d discovered on its base. The gears groaned, and the planets began to spin wildly, faster and faster, until they were a blur. The green light intensified, and the shadowy figure reappeared, more solid than before. It now had a face—or rather, a hole where a face should be, filled with tiny, shimmering stars that looked back at her like a thousand eyes. It spoke, not in words, but in images. She saw Port Merrow flooded, its streets swarming with creatures made of seaweed and bone. She saw her great-uncle standing on the shore, his arms outstretched, welcoming the chaos. And she saw herself, holding the key, laughing as the water rose around her.

Mara wrenched the key free, and the orrery fell silent. But the damage was done. The wall where the shadow had stood now bore a black, charred mark, and the books on the shelf were rearranged to spell out a single word: ‘FINISH.’ Terrified, she called Leo, begging him to come home. But when he answered, his voice was oddly calm, almost distant. ‘I’m already here,’ he said. She turned, and the shadow stood in the doorway, wearing Leo’s skin. Its smile was too wide, and its eyes were the same shimmering stars.

‘You’ve opened the door,’ it said, in Leo’s voice but layered with the sound of waves. ‘Now you must close it. But closing requires a sacrifice.’ It held out a knife, the same one that had hung on the wall in her childhood home, a dagger she’d inherited from her grandfather. It was rusted, but the blade glinted with an otherworldly sheen. ‘Choose,’ it said. ‘The town, or yourself.’

Mara looked at the key still in her hand, then at the orrery, which had begun to hum again. She understood. The orrery was a lock, and her blood was the only lubricant that would turn its gears. She pressed the key to her palm, and the blade of the dagger followed. As her blood dripped onto the brass, the shadow screamed, a sound like a thousand gulls. The planets spun in reverse, and the green light flickered and died. The room fell silent. The shadow vanished, and Leo collapsed to the floor, gasping. When he looked up, he was himself again, but his eyes held a haunted look. The orrery was still, its planets now arranged in a pattern she’d never seen before—a spiral that seemed to pull her gaze inward.

She bandaged her hand and helped Leo to his feet. They never spoke of what happened, but they both knew the orrery held its secret. They tried to move, but every time they packed their bags, the orrery would hum, and they’d find themselves unpacking. It was as if it had claimed them. One cold morning, Mara woke to find Leo standing over her, holding the key. His eyes were black, and the stars were back. ‘You tricked me,’ he said, but it wasn’t Leo’s voice. ‘Now you’ll finish what he started.’

She grabbed the dagger from the nightstand, but before she could act, the orrery’s arms snapped forward, pinning her to the bed. The planets spun, and she felt herself being pulled closer, closer to the central sun. She could see her great-uncle’s face in the glow, apologetic and sorrowful. ‘I’m sorry,’ he whispered. ‘But some tides cannot be stopped.’

The last thing she saw was Leo’s face contorting into that star-filled void, and then the green light swallowed everything. Days later, the police found the flat empty. The orrery was gone, but on the wall, burned into the plaster, was a single word: ‘FINISH.’ And in the harbor, the tide came in, higher than it had ever been, and it did not recede for a week.
