A routine watch on the edge of the Orion Nebula turns unsettling when Julia and Vex detect an impossible signal that may be answering them back.
Night on Orion Station had a way of refusing to settle into anything as ordinary as darkness. The twin suns beyond the nebula still painted the station in fractured colour, stretching the shadows into strange, skewed shapes and turning the dust outside from violet to green to a deep, metallic blue. Tonight, though, even the familiar strangeness felt wrong.
The station seemed to hold its breath.
Julia sat alone in the main observation room, her hair pinned into a loose knot that had already come undone at the nape of her neck. The marks of her goggles still lingered on her cheeks. Across the console, indicator lights pulsed in patient rows, and the monitors threw cold bands of light over her hands. Beside her stood Vex, the android assigned to the station's night systems, silent and watchful in the way only machines could be. The rest of the crew were asleep. They had spent the day testing the H-9 gas fields, and the station had finally gone quiet a few hours ago.
Quiet, except for the signal.
It had started as a faint irregularity in the radio astronomy feed, then sharpened into a pattern so clean it made Julia's skin prickle. Not static. Not interference. Repetition. A code repeating itself with the kind of insistence that felt less like data and more like intent.
She leaned closer to the display. The waveform blinked again, identical to the last three pulses.
"What do you make of this, Vex?"
The android turned his featureless blue-lit face toward the screen. "Several explanations remain possible, Julia. A plasma disturbance. A reflected transmission. An unknown natural phenomenon." A pause. "The repetition suggests structure. It may be a message."
Julia let out a slow breath she had not realised she was holding. She had spent her life measuring the universe in numbers and noise, in spectra and probabilities, in things that could be named and filed away. This was not supposed to feel like being watched.
Vex projected the signal into the air above the console. Lines of binary code unfolded in pale light, then shifted, aligning themselves into a pattern neither of them recognised. Julia stared at it until the symbols began to feel less like data and more like a shape trying to form itself inside her head.
Outside the armoured glass, the nebula flashed.
Julia looked up so fast her chair scraped back. A bright ripple had moved through the dust clouds, not random, not distant. Intentional. It passed behind the station's outer frame and vanished, leaving behind a thin afterimage that pulsed once in the dark.
"Did you see that?" she whispered.
Vex was already checking the feed. "Yes. The source has shifted closer to the platform."
The signal in Julia's headset changed at the same moment. The cadence tightened. Faster now. Sharper. As if whatever was sending it had noticed them listening.
She stood. "We need to look outside."
Vex did not answer at once. When he finally did, his voice had the faint metallic edge it only showed when he was running too many calculations at once. "That would be unwise, given the current readings."
"Which means it's probably the only way to understand them."
For a second, the room was still except for the soft electronic hum of the console. Then Vex gave a single, precise nod.
They suited up in silence and crossed the airlock together. Julia's pulse hammered hard enough to blur the edges of her thoughts. The exterior platform opened onto the nebula's vast, bruised glow, and the cold reached through her suit as soon as the outer door sealed behind them.
The sky ahead of her shivered.
In the centre of the dust cloud, something was forming. Not a comet, not a flare, not any natural thing Julia could name. It was gathering itself piece by piece, as if a shape hidden in the nebula had begun pressing outward, trying to force a path through the dark.
Then the signal came through her headphones again, no longer a pattern but a rhythm. Close. Measured. Precise enough to make her stomach turn.
The platform gave a sudden, violent tremor.
Julia gripped the rail and looked at Vex. His blue-lit face reflected the growing brilliance in the sky, but for the first time since she had known him, he looked uncertain.
The light surged higher, burning white at the centre, and the shape inside the nebula moved as if it had heard them.
Julia raised her eyes to the glare, and when the darkness split open before her, she saw....
