On the edge of known space, Perseus Station picks up a signal that should not exist. When the message changes, Stella and her team realise something in the dark is listening back.
Perseus Station drifted above the black curve of the gas giant like a wound of light, its outer panels blinking against the void. Inside the Discovery Chamber, Stella hovered with one hand braced against the console, watching a string of readings that refused to make sense.
A week earlier, during a routine sweep of the sector, the station had caught a pulse from empty space.
Not debris. Not static. A pulse.
Raul slid into position beside her, his eyes fixed on the live feed scrolling across the display. "It’s still there," he said. "And it keeps changing. Not random, either. It almost feels deliberate."
"Feels?" Stella asked.
He gave her a sharp look. "Look at the pattern. It repeats in layers. Like a message being rewritten while we listen."
Anya arrived a moment later, carrying a tablet crowded with translations, symbol sets, and half-finished notes from every language archive Earth had ever sent up the well. She took one look at the waveform and said nothing, which unsettled Stella more than any alarm.
For hours they worked in shifts of sound and light, replaying the signal, isolating fragments, comparing frequencies, hunting for anything that might mean intent. The station seemed to lean into the silence around them. Even the ventilation hum felt too loud.
Then Perseus slipped into the shadow of the planet.
The signal cut out mid-breath.
Every monitor in the chamber blinked once, hard and white. A crackle shivered through the speakers, low and close, as if someone had brushed a fingertip across the inside of the hull. Stella straightened. Raul froze over the chart. Anya’s hand stopped above her translator.
A symbol flashed onto the central screen.
It was nothing like the alphabets they had been testing. It was sharp, geometric, and gone almost before her eyes could fix on it. The chamber fell into a silence so complete Stella could hear her own pulse hammering in her ears.
Outside the panoramic window, something moved in the darkness beyond the station - slow, thin, and unmistakably real.
