The Invisible City

Four teenagers from the Knot estate discover that each of them has a strange new power. When a blue glow appears beneath an abandoned garage, curiosity pulls them toward something they may not be able to stop.

The sun was dropping behind the grey towers on the Knot estate, stretching the shadows across the empty playground. The four of us sat on the cracked swings as if we owned the place: me, Lena, Artur and Kajetan. We were old enough to want answers and too young to know what to do with them.

Most days, we looked like any other group of teenagers. School. Bad jokes. Messages flying through Messenger long after midnight. Arguments with parents, then pretending they didn't matter. But lately, something had shifted. Small things at first. Impossible things.

Lena was the first to notice it. She always knew the answer before anyone else, always saw patterns in things the rest of us missed. Then, during a maths test, she froze, staring at the paper as if the numbers had lit up in front of her. Later, when she called me that night, her voice had dropped to a whisper.

"It was like the answers were already there," she said. "Like I could see them hanging in the air."

A week later, Artur did something even stranger. During a school tournament, he kicked a ball that should have gone wide. Instead it curved through the air in a way no normal shot ever could, bending around two defenders and slamming into the net. For one second, he said, everything around him felt slow, thick, almost frozen.

Kajetan laughed when Artur told us. He always laughed first, as if that could keep fear from getting too close. But then Kajetan had his own moment. In a corner shop, a man tried to snatch an old woman's wallet. Kajetan grabbed his arm without thinking. He was thin as a branch, yet he held the man in place until the police arrived. He couldn't even explain how he'd done it.

I thought I was the only one left untouched. Then, in maths, the teacher's voice split in two inside my head. One part kept talking at the board. The other sounded like a murmur under water. I looked around the room and realised I could hear the thoughts of the people sitting nearest me. Not their words. Their real thoughts.

I nearly bolted from the classroom.

When we finally admitted everything to one another, we came here, to the playground, just before dark. The evening air felt heavy, as if the estate itself was holding its breath. Lena tore leaves from a hedge without looking at them. Artur kept staring at his phone, not really seeing it. Kajetan paced in a tight circle, restless as an animal in a cage. I tried to shut out the noise in my head, but the thoughts around me kept pressing in, sharp and чужe and close.

None of us knew where these powers had come from. None of us knew whether they were a gift or a warning. The city was sinking into night when a blue light flickered under the entrance to the old underground car park. We all saw it at the same time.

Nobody had used that entrance in years. Now the door stood half-open, and something inside was pulsing, slow and cold, like a second heartbeat buried beneath the estate.

We looked at one another. Nobody said it, but we were all thinking the same thing: if we walked away now, we would spend the rest of our lives wondering what was down there.

So we moved toward the entrance, step by step, until the glow washed over our faces and the air began to hum around us. Then the first bang split the silence.
