In neon-lit Aurora, three strangers with hidden powers collide in an underground station as a strange signal and a voice from nowhere pull them into a dangerous test.
Aurora never really slept. Its glass towers caught the neon and threw it back in restless colours, while the streets below stayed busy with late-night crowds, shuttered cafés, and doors that only opened for people who knew exactly where to knock. On a humid June night, the underground SkyLine station hummed beneath it all, bright, cold, and almost empty.
Lena stood near the platform edge with her notebook tucked under one arm, pretending to read the arrival board. Bioengineering by day, sleeplessness by habit, and a gift she had never dared to name in public. Her hands could knit skin and muscle back together faster than any treatment she had ever studied, as if her body had decided rules were optional.
Across the platform, Michael crouched beside a service pillar with a portable decoder balanced in both hands. He worked IT contracts for the kind of clients who paid in unmarked transfers and asked no questions. Tonight he was chasing a signal that kept breaking through the city network like a pulse under the skin of the wires. Every time he got close, the display twisted into static.
Iga lingered near the ticket machines, a paper cup cooling in her fingers. At the café where she worked, she had learned to read people by the pauses between their words. One accidental touch had taught her why. She could pull memories to the surface with frightening ease, and lately she had been feeling the edge of someone else in her mind, patient and watchful.
They would have stayed strangers if the lights had not failed.
A sharp flicker ran through the station. The platform dropped into darkness. For three heartbeats, the city vanished.
When the lights snapped back, Lena was staring at Michael, Michael was staring at the decoder, and Iga had turned toward the wall where a luminous symbol burned into the concrete: a spinning wheel ringed by three stars. Ozone stung the air. Somewhere behind them, footsteps moved where there had been no one a moment before.
Lena took a slow breath. "Tell me I'm not the only one seeing this."
Michael's screen flared red. His voice came out thin. "That signal isn't coming through the network. It's coming through something else."
Iga felt the chill before she saw them. Dark shapes were gathering at the far end of the platform, cloaks swallowing the light, faces hidden, their movements too smooth, too precise to belong to ordinary commuters.
Then the symbol on the wall pulsed once, hard as a heartbeat, and a voice rolled through the station, metallic and calm:
"You have been chosen. The city is running out of time. Prepare for the test."
The shadows around them began to move.
